The cursor is located in the Enter Selection field. Type the letter that precedes the function you want and press Enter. To return to the Administrator Main Menu, press the Prev Menu, Main Menu, or Exit key. The functions that can be accessed from this menu are discussed in the remainder of this chapter.

Card Maintenance

Use Card Maintenance to add cards to or delete cards from the database and change the status of a card, a port on a card, or a span on a card.

Accessing the Card Maintenance Screen

Complete the following steps to access the Card Maintenance screen:

Step 1 Access the Maintenance Menu screen (refer to the "Accessing the Maintenance Menu Screen" section).

Step 2 Type A and press Enter.

The Card Maintenance Menu screen appears (see Figure 5-3). The cursor is located in the ADD, DELETE, CHANGE STATUS (A,D,C,P) field.

Figure 5-3: Card Maintenance Screen

Card Maintenance consists of up to 15 screens. Each screen lists 11 card entries, ordered according to their location within the system. A message towards the bottom of each screen states the number of time slots for which your system is licensed (actual number of purchased time slots) and how many time slots are currently in use (allocated).

Note In the example in Figure 5-3, 1152 time slots were purchased for that switch, of which 272 have already been allocated. The time slot information on the Card Maintenance screen should match the time slot information displayed on the main menu and License Configuration screens.

Use the Prev Screen and Next Screen keys to page through the listings. Use the Print Screen key to obtain a hard copy of any of these screens.

Card Maintenance Screen Field Definitions

The Card Maintenance screen contains the following fields:

R L S—Display only. The Rack-Level-Slot/Group/Span hardware address (physical location) of the card.

CARD TYPE—Display only. Shows the kind of card in that location. You can change this field using the ADD, DELETE, CHANGE STATUS AND PORT DEFINITION (A,D,C,P) field.

V.RV—Display only. The version and revision level of the firmware installed on the card. Use this field to verify that firmware revisions for all network interface and service circuit cards are at the current level. The information in this field appears only if the status (S) of the card is other than Out of Service (O). For a listing of current firmware version/revision levels, refer to the current customer release notes.

Note If you are running a customer patch, you may see an inconsistency in the SPC.DWN and ICC.DWN file version revision numbers listed in this column. The inconsistency is due to the two character field length; customer patch version revision numbers are greater than two digits and the system converts them to binary coded digits for display purposes. Formal releases always contain two digits and do not experience this inconsistency.

S—Display only. The current status of the card. You can change this field using the ADD, DELETE, CHANGE STATUS AND PORT DEFINITION (A,D,C,P) field. Valid values are:

: A—Active. Ports on this card can be involved in active calls and can be allocated to new calls.
: O—Out of service. No ports on this card can be involved in active calls; no ports are allocated to new calls.
: S—Standby. Valid for one of the two NBC3s in redundant systems only, one of the two DTG or DTG-2s in redundant systems, redundant BRCs, or redundant Subrate Switching Cards (SSCs).
: M—Maintenance. One or more ports on this card may be involved in active calls; no ports are allocated to new calls.
: D—Diagnostics. No ports on this card are involved in calls or allocated to new calls.
: C—Camped on. Status change to Diagnostics mode was attempted while ports on this card were still involved in calls; no ports are allocated to new calls; card remains in this mode until you take further action.
: R—Remote Loopback. Valid only for PRI and programmable trunk cards.
: P—Payload Loopback. Valid only for programmable trunk cards.

ADD, DELETE, CHANGE STATUS AND PORT DEFINITIONS (A,D,C,P)—Data entry via main keypad. Specifies the function to perform.

Note You can add or delete Four Span T1/E1, MVDC T1, and ICC cards while the change state and port options are performed on a span. Operating on a span requires an interface identifier (i.e., 1 1 4-3, or 1 1 4-3-1 for ICC and SPC cards).

Note You have the option of changing the status of all spans of an MVDC T1 or ICC card with a single command, or specifying a particular span. For example, to activate a card, type 1 1 4 and all spans in slot 4 are activated.

Adding a Card

You can add a card to the system database from the Add function of the Card Maintenance screen. The card does not have to be installed in the system before it can be added to the database.

Consider the following when adding a card to the database:

When a card other than a programmable trunk card is added, its initial status is O (out of service). Use the Change Status function to bring the card on line and make it available for use by the system. Refer to the "Changing the Status of a Card" section for information on the Change Status function.
When you add a programmable trunk card (Four Span T1, Four Span E1, MVDC T1, and ICC), all ports are allocated. When a programmable trunk card is deleted, all spans must be OOS. Ports are displayed one span at a time. The download occurs when the first span is activated.
When adding an NBC3 card, the card location must have an R-L-S of either 1 1 1-1 or 112-1. No other hardware address is valid for an NBC3.
A BRC can reside in Slots 3 to 16 of the Master Port Subrack or Slot 1 or 2 of an Expansion Port Subrack.

Note BRCs are only supported in VCO/80 and SDS-1000 systems.

Deactivate individual ports on a card or span when you add a card by combining the Add command with the Port Definition command. Directions for this operation are included in this subsection. Refer to the"Changing the Status of a Port" section for more information on the Port Definition command.
Except for DRC 24, DRC 48, and SPC-DTMF, each port on a card consumes one time slot of the total time slots licensed. When you add a new card to the database, the number of available time slots is reduced by the number of ports on the card. When you are within 64 time slots of your Time slot Allocation Capacity, you are warned with a message. When adding a new card causes the number of ports to exceed the timeslot capacity, an error message is displayed and you are unable to add this or other cards to the system until you remove existing cards or upgrade your Timeslot Capacity License. (Contact your Cisco Systems Sales Representative for information on upgrading your license.)

Note Each SPC-TONE, DTG-2 or DTG consumes 64 time slots. These time slots are "free," that is, provided at no charge by Cisco. The number of time slots available is adjusted upward to reflect the free DTG time slots, as displayed in the Card Maintenance, License Configuration, and main menu screens. Sixty-four time slots in the range of 0x4C0 to 0x4FF are reserved for each service engine configured as SPC-TONE.

You can adjust the number of time slots required for a 64- or 128-port IPRC card by modifying the PLAYBACK PORTS field on the IPRC Card Configuration screen.
When adding a Subrate Switching Card (SSC), you must first allocate the ports. To allocate SSC ports, go to Database Administration, then to the Subrate Configuration screen. Type the number of ports to be allocated, in multiples of 8, in the Timeslots Allocated for Subrate field.

Complete the following steps to add a card to the database:

Step 1 Access the Card Maintenance screen (refer to the "Accessing the Card Maintenance Screen" section).

The Card Maintenance screen appears. The cursor is located in the command field.

Step 2 Type A and press the Next Field key. The cursor moves to the first R-L-S field.

Step 3 Type the physical location: rack/cabinet number, level number, and slot number, and press the Next Field key after each entry.

The cursor moves to the Card Type field and the "Hit 'Select' Key To Select Card Type..." message appears.

Step 4 Use the Select and Reverse Select keys to scroll through the values until the correct card type is displayed.

Note The Announcement and Primary Rate/DSS1 card types, although selectable, are not supported.

Step 5 Deassign ports as required:

If no ports are to be deassigned (marked as unavailable) at this time, proceed to Step 6.
To deassign individual ports, use the Next Field key to advance the cursor to the port(s) to be placed out of service. Use the space bar to eliminate information in that field and deassign the port(s).

Step 6 Press Enter.

The "Card Is Added, But Out Of Service!" message appears as the database is automatically updated. The screen display is updated to show the addition of the card to the list. The Status field indicates the card is out of service, and all ports are shown as available. The cursor returns to the command field.

Step 7 Repeat Step 2 through Step 6 for all cards you want to add.

Step 8 Press the Exit key to return to the Maintenance Menu screen, or remain at this screen to change the status of the new cards.

To exit the Card Maintenance screen without making any changes, press the Exit, Prev Menu, or Main Menu key. No changes are made to the database unless Enter is pressed.

Changing the Status of a Card

You can place cards and spans in Active, Out of service, Diagnostics, Maintenance, Remote Loopback, or Payload Loopback mode using the Card Maintenance screen.

Consider the following when making card and/or span status changes:

A card must be in the database before its status can be changed.
When you change a card to Active, the screen is not updated until the card is brought into service.
If you place a card into Active or Maintenance mode, you must first physically install it in the system.
To reset an active card, change the status from Active to Out of Service then back to Active.
You can place a card into Diagnostics mode only if it is already in Active or Maintenance mode.
When you change a card to Out of service, any calls linked to the ports on that card are torn down. If any ports on the card are involved in active calls, a message indicating the number of ports on the card that are involved in active calls is displayed, along with a prompt to continue or abort the process. If you continue, the calls are torn down and the card status is changed. If you abort the process, there is no change to the card status or the active calls.
You can change a card with ports involved in active calls from Active to Maintenance or Diagnostic mode without affecting calls in progress (except for programmable trunk cards; refer to the next item in this list). When the card mode is changed from Active, ports on the card are no longer hunted for call allocation.
You can change cards other than programmable trunk cards to Active, Maintenance, Out of service, Diagnostics, or Remote Loopback mode. (Remote Loopback only applies to PRI/N cards.)
You can change programmable trunk cards to Active or Out of service mode. When a programmable trunk card is active, each span can be changed to Active, Maintenance, Out of Service, Diagnostics, Remote Loopback, or Payload Loopback. (Payload Loopback applies only to programmable trunk cards in ESF mode. In this mode, the T1 stream is looped back to the network with a new frame.)
When a programmable trunk card changes from Active or Maintenance to Diagnostics mode, any calls linked to the ports on that card are torn down. If any ports on the card are involved in active calls, a message indicating the number of ports on the card that are involved in active calls is displayed, along with a prompt to continue or abort the process. If you continue, the calls are torn down and the card status is changed. If you abort the process, there is no change to the card status or the active calls. On programmable trunk cards the T1 signal is looped back to the card while it transmits a signal consisting of all unframed ones. This causes a loss of carrier on Rev. B T1 cards.
The status of an NBC3 cannot be changed from this function. BRC switchover is caused by changing one of the active BRCs to Out of Service. The redundant pair then automatically transitions to active while the first pair is reset and is placed in standby mode. A BRC can be changed to Out of Service only if there is a redundant BRC pair for the affected subrack, and that pair is in standby mode. BRCs cannot be placed into Maintenance, Standby, or Diagnostic mode; only Active or Out of Service. BRCs are Active only in pairs; if one card in the pair goes out of service (such as when it is physically removed from the rack), the other card transitions to standby causing immediate loss of service to the port subrack in systems with nonredundant BRCs.
You can take DTG or DTG-2 cards out of service only if another DTG or DTG-2 in standby mode exists in the subrack.
When an IPRC is changed to Active mode, the voice announcement application is downloaded to it automatically from hard disk, if necessary. IPRCs are only downloaded following a power-up reset or if the application on the card does not match the download file on the system disk. If a download is not successful, the card remains in Maintenance mode. If the download is successful, the voice prompt information is downloaded and the IPRC goes to Active.

Note Any active IPRC that has not had prompts downloaded to it has a status of Maintenance.

When a CPA is changed to Active mode, the tone detection application is downloaded to it automatically from hard disk, if necessary. CPAs are only downloaded following a power-up reset or if the application on the card does not match the download file on the system disk. If a download is not successful, the card remains in Maintenance mode (any active CPA that is downloaded has a status of Maintenance). If a download is successful, the CPA goes to Active. When a status change to Diagnostic mode is performed, the system checks if any ports on the card specified are linked to a call. If one or more ports are active, the card is placed into Camped On mode. Diagnostic routines can now be run; the system skips any ports linked into a call. If, later, you attempt to change from Camp On to Diagnostics, the system again checks if any ports on that card are still linked into a call. If so, the "Ports Still Active, Left In Camp On" message is displayed.
Remote Loopback mode applies only to PRI and programmable trunk cards. This mode allows you to run diagnostics on the total loop (trunks from the far end interface to the VCO and back to the far end). The card must first be Active before its status can be changed to Remote Loopback. Refer to the Cisco VCO/4K ISDN Supplement and the Cisco VCO/4K Technical Descriptions for more information on the ISDN PRI option.
Do not change the status of a DTG to out of service if the VCO/4K is configured with both DTG and SPC-OUTP outpulsing resources, unless you first verify that the SPC-OUTP is in service and added to a resource group.

Complete the following steps to change the status of a card:

Step 1 Access the Card Maintenance screen (refer to the "Accessing the Card Maintenance Screen" section).

The cursor is located in the ADD, DELETE, CHANGE STATUS AND PORT DEFINITION (A,D,C,P) field.

Step 2 Type C and press the Next Field key.

The cursor moves to the first R-L-S field.

Step 3 Type the physical location: rack/cabinet number, level number, and slot number, and press the Next Field key after each entry.

The display is updated to show the card type, current status, available ports, and the screen that contains the selected card's listing, if not already displayed. The cursor moves to the State field and the "Type Status, Then Depress Enter!" message appears.

Note For Four Span T1/E1 and MVDC T1 cards, you must specify the span, otherwise the message "Interface Required" appears. For ICC and SPC cards, you must specify the group and interface.
When changing the status of a multi-span card, you do not need to specify a particular span, although this option is still available. For example, to activate all spans of a multispan card, type 1 1 14 and all spans in slot 14 become active.

Step 4 Type the appropriate character in the Status field and press Enter. Refer to "Card Maintenance Screen Field Definitions" section for field descriptions.

If you type O, or if the card type is a programmable trunk card and you typed D, proceed to Step 5.
If you type A, D (other than a programmable trunk card), M, or R, the database is automatically updated and the screen display is updated to indicate any additional status messages and the change of status when it occurs. The cursor returns to the ADD, DELETE, CHANGE STATUS AND PORT DEFINITION (A,D,C,P) field and the "Card Status Is Changed" message appears.

If no ports on the specified card are involved in active calls, the database is automatically updated and the screen display is updated to show the change of status when it occurs. The cursor returns to the command field and the "Card Status Is Changed" message appears.

If ports on the card specified are involved in active calls, the "xx ports active, Continue/Abort (C/A)" message appears.

Step 5 Perform the status change in one of the following two ways:

To perform the status change now, type C and press Enter.

: All ports on this card involved in active calls are detached and the calls are torn down. The database is automatically updated and the screen display is updated to show the change of status when it occurs. The cursor returns to the ADD, DELETE, CHANGE STATUS AND PORT DEFINITION (A,D,C,P) field and the "Card Status Is Changed" message appears.

To abort and attempted later, type A and press Enter. The "Operation Aborted" message appears. (There is no effect on any call in progress and the card status is not changed.)

Step 6 Repeat Step 2 through Step 5 for all status changes you want to make.

Step 7 Press the Exit key to return to the Maintenance Menu screen.

To exit the Card Maintenance screen without making any changes, press the Exit, Prev Menu, or Main Menu key. No changes are made to the database unless you press Enter.

Deleting a Card

Use the Delete function on the Card Maintenance screen to delete a card from the system database. Consider the following when deleting a card from the system database:

A card must be out of service to be deleted, and all ports on that card must be removed from their resource group. Refer to the "Changing the Status of a Card" section for information on changing the status of a card.
Refer to "Database Administration," for information on the Resource Group Summary and Configuration functions.

Complete the following steps to delete a card from the database:

Step 1 Access the Card Maintenance screen (refer to the "Accessing the Card Maintenance Screen" section).

The cursor is located in the ADD, DELETE, CHANGE STATUS AND PORT DEFINITION (A,D,C,P) field.

Step 2 Type D and press the Next Field key.

The cursor moves to the first R-L-S field.

Step 3 Type the physical location: rack/cabinet number, level number, and slot number, and press the Next Field key after each entry.

Note You can delete an MVDC T1, ICC, or SPC by card or by span. To delete by card, type the rack, level, and slot numbers. To delete by span, type the rack, level, and slot/group/span or interface.

The display is updated to show the card type, current status, available ports, and the screen that contains the selected card's listing, if not already displayed. The "To Delete Card, Depress Enter!" message appears.

Step 4 Press Enter.

The "Are You Sure? Then, Depress Enter!" message appears.

Step 5 Press Enter.

Step 6 The database is automatically updated and the screen display is updated to show the modifications. The cursor returns to the ADD, DELETE, CHANGE STATUS AND PORT DEFINITION (A,D,C,P) field, and the "Card is Deleted" message appears.

Step 7 Repeat Step 2 through Step 5 for all cards you want to delete.

Step 8 Press the Exit key to return to the Maintenance Menu screen.

To exit the Card Maintenance screen without making any changes, press the Exit, Prev Menu, or Main Menu key. No changes are made to the database unless you press Enter twice.

Changing the Status of a Port

You can mark individual ports on an internal service circuit or network interface card as unavailable (0) from the Port Definition function on the Card Maintenance screen. Ports previously marked as unavailable can also be returned to use (1) with this function. This function is also known as activating or deactivating a port.

Consider the following when changing the status of a port:

If you use the Diagnostics Set Up Path function, first deactivate the port for which a path is to be set by entering P. While the port is deactivated, it cannot be allocated to a call. To make the port available for use, enter P to activate it.
Use the P command to reset a port. First deactivate the port, then reactivate it.
Because the NBC3s and BRCs have no ports, you cannot use this command for those cards. If you use this command for these cards, the system displays an error message.
When you deactivate one or more ports, the system checks to see if any are involved in active calls. If so, a message indicating the number of ports involved in active calls is displayed, along with a prompt to continue or abort the process. If you continue, the calls are torn down and the ports are deactivated. If you abort the process, there is no change to the port or the active calls.
When you deactivate a port, call processing no longer attempts to allocate it to any call; you do not need to remove the port from its resource group. This allows maintenance personnel to minimize the effects of a single port failure on the system.
Outgoing ports that were deactivated by the Auto Makebusy feature are displayed in the same way that ports were deactivated from this screen: the port field contains 00. Ports deactivated by Auto Makebusy can be reactivated from this screen. (The Auto Makebusy feature monitors alarm thresholds for outgoing ports. When the alarm threshold for a port is exceeded, Auto Makebusy automatically deactivates that port.)

Complete the following steps to change the status of a port:

Step 1 Access the Card Maintenance screen (refer to the "Accessing the Card Maintenance Screen" section).

The cursor is located in the ADD, DELETE, CHANGE STATUS AND PORT DEFINITION (A,D,C,P) field.

Step 2 Type P and press the Next Field key.

The cursor moves to the first R-L-S field.

Step 3 Type the physical location: rack/cabinet number, level number, and slot number, and press the Next Field key after each entry.

The display is updated to show the card type, current status, available ports, and the screen that contains the selected card's listing, if not already displayed. The cursor moves to the first Port field and the "Type Port Numbers, Then Depress Enter!" message appears.

Note For Four Span T1/E1 and MVDC T1 cards, you must specify the span or the message "Interface Required" appears. For ICC and SPC cards, you must specify the group and interface.

Step 4 Use the Prev Field, Next Field keys, and the main keypad, to move the cursor to the desired port. Ports are organized sequentially, in clusters of eight.

a. To remove a port from service, move the cursor to the port and type 0.

b. To make a port available, move the cursor to the port and type 1.

Step 5 After you change the status of a port, press Enter.

Step 6 Complete one of the following options, which are dependent upon your configuration requirements:

If no ports are being deactivated or if none of the ports specified to be deactivated are involved in active calls, the "Adjusting Ports" message appears while the database is being updated.

: When completed, the display is updated and the "Done!" message appears.

If any of the ports specified are involved in active calls, the "xx ports active, Continue/Abort (C/A)" message appears. Proceed to Step 7.

Step 7 Complete one of the following options, which are dependent upon your configuration requirements:

To perform the status change now, type C and press Enter.

: All ports specified that are involved in active calls are detached and the calls are torn down. While the database is being updated, the "Adjusting Ports" message appears.
: When completed, the display is updated and the "Done!" message appears.

To abort the status change and try again later, type A and press Enter.

: The "Operation Aborted" message appears.
: The cursor returns to the ADD, DELETE, CHANGE STATUS AND PORT DEFINITION (A, D, C, P). There is no effect on any call in progress and the card status is not changed. Proceed to Step 8.

Step 8 Repeat Step 2 through Step 7 for any cards on which you want to change port status.

Step 9 Press the Exit key to return to the Maintenance Menu screen.

To exit the Card Maintenance screen without making any changes, press the Exit, Prev Menu, or Main Menu key. No changes are made to the database you press Enter.

Disk Utilities

The Disk Utilities menu provides access to the DOS-based utilities that allow you to perform the following functions:

View directory listings for the hard and floppy disks
Copy files between the hard and floppy disk or to another directory on the hard disk
Delete files from the hard or floppy disk
Rename files
Store all database files on floppy disk (database backup)
Retrieve all database files from a floppy disk
Display the contents of a file (in hex)
Show how much free space exists on the hard or floppy drive
Format the hard disk
Install and remove multiple tone plan feature tone plan files

The system hard and floppy drives use the same DOS disk format as IBM-compatible PCs. The system floppy disk drives require 3.5-inch double-sided, high-density (DS, HD) diskettes. Floppy disks formatted or copied on a DOS PC are compatible with the system. There are some differences between PC-DOS and system DOS; refer to the "Filename Conventions" section.

Filename Conventions

To move system files, use the same basic filename conventions as standard PC-DOS, with the exception of the backslash (\) character. Files are identified by a drive specifier (A: for floppy drive and C: for hard drive), a filename of between one and eight alphanumeric characters, and a three-character filename extension following a period (.ext). In addition, you can specify a file as part of a directory path. The VCO/4K file system requires you to use a forward slash (/) character to separate directories and filenames (similar to UNIX) rather than standard PC-DOS backslash (\) character.

Two wildcard characters can also be used within filenames and extensions:

A question mark (?) is a single-character wildcard.
An asterisk (*) is a multi-character wildcard.

When you use a question mark (?) in a filename or extension, it indicates that any character can occupy that position. For example, the filename AB?DE.XYZ specifies all filenames with five characters, begin with AB, have any next character, are followed by DE, and end with the extension XYZ.

When you use an asterisk (*) in a filename or extension, it indicates that any character can occupy that position. It also indicates that any characters can occupy the remaining positions in the filename or extension. The asterisk wildcard is commonly used to specify all files with the same extension (*.XYZ) or all files with a common filename (ABCDE.*).

Two terms are used to describe the relationship of files during a Copy File operation:

Source file—the original file being copied (Copy From? field).
Destination file—the original file being copied (Copy From? field).

Note These terms appear both in this text and in messages written to the screen and system log file.

Accessing the Disk Utilities Menu Screen

Complete the following steps to access the Disk Utilities Menu screen:

Step 1 Access the Administrator Main Menu screen.

Step 2 Access the Maintenance Menu screen (refer to the "Accessing the Maintenance Menu Screen" section).

Step 3 Type B and press Enter.

The Disk Utilities Menu screen appears (see Figure 5-4). The cursor is located in the Enter Selection field.

Figure 5-4: Disk Utilities Screen

Use the Print Screen key to obtain a hard copy of this screen.

The Disk Utilities Menu screen options are described in the following sections:

Show Directory

Use the Show Directory option to view a list of all directories and files contained in a specified directory on either the system hard drive (C:) or floppy drive (A:). To view a directory on the floppy drive, insert the floppy disk into the drive before you press Enter. The system displays the following information:

File/Directory name—The name of the file. Directories are indicated by the characters <DIR> following the directory name.
File Extension—The three-character file extension for that file. Directories do not have a file extension.
File Size—The size of the file in bytes. Directory sizes are not displayed.
Creation Date—The date the file or directory was created or altered.
Creation Time—The time (in HH:MM:SS format) at which the file was created or altered. A 24-hour clock format is used, for example, 15:30:00 is 3:30 p.m.

Complete the following steps to view a directory listing:

Step 1 Access the Disk Utilities Menu screen (refer to the "Accessing the Disk Utilities Menu Screen" section).

Step 2 Type A and press Enter.

The Disk Directory screen appears (see Figure 5-5). The cursor is located in the data entry field.

Figure 5-5: Disk Directory Screen

Step 3 Perform one of the following actions, which is dependent upon your needs:

To list a hard drive (C:) directory, proceed to Step 4.
To list a floppy drive (A:) directory, insert the floppy diskette into the drive and proceed to Step 4.

Step 4 Type the complete directory name you wish to display (including the drive designation), and press Enter.

The "Reading Directory" message appears while the system accesses the specified directory. The screen then clears and displays a directory listing similar to that shown in Figure 5-6. The number of files in the directory is shown on the message line.

Step 5 To view another directory, press the Exit key and return to Step 3.

Figure 5-6: Hard Disk (C:) Directory Sample

To return to the Disk Utilities Menu screen before viewing another directory, press Enter.

Copy Files

Use the Copy Files option to copy files from one disk to another, and to copy files from one directory to another on the same disk.

If the file already exists on the destination disk, it is overwritten by the source file. A system status message shows the number of files copied. Use of wildcards in specifying filenames is supported as described in the "Filename Conventions" section.

Copy a single file by specifying the source and destination filenames. This process is especially useful when updating card download files, such as NBC or ICC downloads (NBC.DWN and ICC.DWN, respectively). The following example specifies to copy the ICC download file from the top-level directory on the floppy disk to the top-level directory on the hard disk. The destination filename in this example is the same as the source filename:

Source file—A:ICC.DWN
Destination file—C:/BOOT/ICC.DWN

You can copy all Trace files on the system hard disk to a Trace directory on a floppy disk by specifying the following source and destination files:

: Source file—C:/TRACE/*.*
: Destination file—A:/TRACE

Complete the following steps to copy one or more files:

Step 1 Access the Disk Utilities Menu screen (refer to the "Accessing the Disk Utilities Menu Screen" section).

Step 2 Type B and press Enter.

The Copy Files screen appears (see Figure 5-7). The cursor is located in the Copy From? field.

Figure 5-7: Copy Files Screen

Step 3 Complete one of the following steps, which is dependent upon your configuration needs:

To copy a file from one directory to another on the hard drive (C:), proceed to Step 4.
To copy a file between the floppy drive (A:) and the hard drive (C:), insert the floppy disk into the drive and proceed to Step 4.

Step 4 Type the filename you wish to copy and press the Next Field key.

The cursor moves to the Copy To? field.

Step 5 Type the destination filename and press Enter.

The "Copying Files" message appears while the system copies the specified file. When copying is complete, the "X Files Copied" message appears, where X indicates the number of copied files. The system automatically returns to the Disk Utilities Menu screen after several seconds.

Delete Files

Use the Delete Files option to delete files from either the hard or floppy disk. A system status message shows the number of files deleted. Use of wildcards in specifying filenames is supported as described in the "Filename Conventions" section.

Delete a single file by specifying its filename. The following example specifies to delete the ICC download file from the hard disk:

: Filename to delete—C:ICC.DWN

Delete all system log files on the hard disk by specifying the following filename:

: Filename to delete—C:/LOG/*.*

Complete the following steps to delete one or more files:

Step 1 Access the Disk Utilities Menu screen (refer to the "Accessing the Disk Utilities Menu Screen" section).

Step 2 Type C and press Enter.

The Delete Files screen appears. The cursor is located in the Delete What Files? field—the only field on the screen.

Step 3 Complete one of the following steps, which is dependent upon your configuration needs:

a. To delete a file from the hard drive (C:), proceed to Step 4.

b. To delete a file from a floppy disk (A:), insert the floppy disk into the drive and proceed to Step 4.

Step 4 Type the filename you need to delete and press Enter.

The screen is refreshed and displays a list of the files to be deleted. The "OK TO DELETE FILES <Y/N>?" message appears.

Step 5 Type Y and press Enter to delete the files indicated.

Note If you type N and press Enter, the display to returns to the Disk Utilities Menu screen and the operation is aborted.

When deleting is complete, the "X Files Deleted" message appears, where X signifies the number of files that were deleted. The system automatically returns to the Disk Utilities Menu screen after several seconds.

Rename Files

Use the Rename Files option to change the name of a file. If the device is also changed as part of the rename operation, the source file is deleted.

Note Use of wildcards in specifying filenames is not supported for the Rename Files function.

Uncompress File

Use the Uncompress File option to expand a compressed file to its original size and content. Refer to the previous section, "Compress File" section for information on compressing files. Consider the following when uncompressing files:

The file to be uncompressed must have a .Z filename extension). If the file to be compressed does not have a .Z extension, rename the file.
When a file is uncompressed, the filename is the same as the compressed filename but without the .Z extension. You can rename the file with an extension.
Any file compressed on the VCO, on a UNIX workstation, or other computer with a utility based on the BSD 3.2 UNIX implementation, can be uncompressed on the VCO/4K.

Note You can enter the filename with or without the .Z extension. If you enter the filename without an extension, the software assumes the .Z extension.

Step 4 Press Enter.

The file is uncompressed.

Split File

Use the Split File option to split a large file into a series of smaller files. This may be required if you need to copy a large file on to a floppy disk.

All files accessible to the VCO switch can be split into a series of smaller files. The algorithm used requires an output filename and the number of bytes for each segmented file. The split function then produces the required number of file parts, each a segment of the original file. The sum of the files produced from the split comprises the total size of the original file.

Consider the following when splitting files:

The recommended split size for floppy disks is 1,440,000 bytes.
There is a maximum of 512 files that may result through the split operation. This should be taken into consideration when indicating the split file size.

Complete the following steps to split a large file into a series of smaller files:

Step 1 Access the Disk Utilities Menu screen (refer to the "Accessing the Disk Utilities Menu Screen" section).

Step 2 Type O and press Enter.

The Split File screeen appears (see Figure 5-11).

Figure 5-11: Split File Screen

The cursor is located at the Split What File? field.

Step 3 Type the drive (C:/ or A:/) and filename of the file to be split.

Step 4 Press the Next Field key to move the cursor to the Split File Size field.

Step 5 Type the size (number of bytes) of each split file segment.

Step 6 Press Enter.

The file has been split into several smaller files.

An example of a split file is described as follows:

File drive and filename—C:core1
Size of files to create—1440000

The resulting file segments are each 1,440,000 bytes. The total of the file segments in bytes equals the original file size. The last file segment may be less than the indicated size, depending on the size of the original file.

The output of the Split File operation results in a series of files with the designated output filename and an extension, as shown below.

filename.xaa
filename.xab
filename.xac
filename.xad

The file extensions increase in alphabetic order as necessary to accommodate the full contents of the original file. For example, if the original core1 file to be split is 8.4 MB, the following split filenames and sizes would result:

core1.xaa—1440000
core1.xab—1440000
core1.xac—1440000
core1.acd—1440000
core1.xae—1440000
core1.xaf—1200000

The total of all split files, core.xaa through core.xaf, is 8,400,000 bytes (or 8.4 MB) which is the size of the original core file.

Join Files

Use the Join Files option to reassemble split files back into the original file. Refer to the "Split File" section for information on splitting files. Joining files requires you to understand the concepts of source and destination files. Refer to the "Joining FilesSource and Destination Files" section.

Joining Files—Source and Destination Files

The source files (the files associated with the Join From? field) are the files that will comprise the new file. The source files are the file segments that resulted from the split file operation.

You can specify the source file by filename with no extension. If the filename is designated without an extension, all files with that filename are joined. The files are joined as if the extension was designated with the multicharacter (*) wildcard. The order is based on the alpha character ordering of the file's extension.

The join operation supports alphabetic ordered wildcard symbols. You can specify the source file with the single-character wildcard—the question mark (?), or the multi-character wildcard—the asterisk (*). The join operation automatically appends the split files in alphabetic order to the destination file.

You may also initiate the join operation for each individual split file by indicating the specific filename with the full extension. Note however, that if this method is used, you must specify the files in the correct order by file extension (alphabetic order) to accurately reproduce the original file.

The destination file (the file associated with the Join To? field) is the file which is to be the composite of all the split files. After joining all file segments, the destination file is identical to the original file before the split process occurred.

Note If the destination filename already exists, the source files are appended to it.

Complete the following steps to join split files:

Step 1 Access the Disk Utilities Menu screen (refer to the "Accessing the Disk Utilities Menu Screen" section).

Step 2 Type P and press Enter.

The Join Files screen appears (see Figure 5-12).

Figure 5-12: Join Files Screen

The cursor is located in the Join From? field.

Step 3 Enter the drive and filename of the source file. Consider the following when entering data into this field:

Note Enter the complete source file path name and filename, with extension, in the Join From? field.
Only one filename can be specified in the Join From? field. However, wildcard characters can be used to join several files. Refer to the next section, Source Files for information on the use of wildcard characters.

Step 4 Press the Next Field key to move the cursor to the Join To? field.

Step 5 Enter the desired name of the destination file—the file which is to contain all source file(s).

Step 6 Press Enter.

The files are joined.

Master Timing Link Selection

Use the Master Timing Link Selection option to select the system T1 or PRI timing source. Timing can be derived from system internal clocking or from an incoming T1 or PRI bit stream. If, when incoming timing is used, the incoming reference is lost, the system automatically tries to resynchronize using the internal clock. Synchronization is discussed further in "T1/PRI Synchronization to Master Timing Link."

You can change T1 synchronization from the Master Timing Link Selection screen or by using the T1 Synchronization Control ($C0 02) command; refer to the Cisco VCO/4K Standard Programming Reference and the Cisco VCO/4K Extended Programming Reference for more information. Both methods allow you to do the following:

Switch to internal synchronization
Switch to external synchronization
Change Master Timing Link for incoming synchronization

Primary only
Secondary only
Both primary and secondary

If you select incoming synchronization from the Master Timing Link Selection screen, you must enter the primary and secondary link values. The link values correspond to the hardware address of the digital trunk card to be used as the timing reference. (If you use the host command, specify a port address residing on that card.) The system verifies that the card specified is on-line, a digital trunk card, and that the primary and secondary values are not the same card. If these conditions are met, the database is updated on both the active and standby sides before the system attempts to synchronize to the new values. Refer to "T1/PRI Synchronization to Master Timing Link," for a flowchart detailing the synchronization process.

Core Dump

The Core Dump option results in the automatic storage of detailed information following a system failure, or at your request (see Figure 5-22).

The information in the core file contains data sets with information regarding the reason(s) the file is being created and why the system failed. The core file contains the following information:

System version, revision, field service release (FSR) number, and PUN number.
Failure mode.
Context of failed task.
Register information.
Time and date.
Memory image (volatile and nonvolatile).

Core Dump Functionality

The system automatically creates a core file when there is an exception, a watchdog timeout, or at your request.

Note the following considerations with automatically created core files:

The core file includes the reason for failure, system data, context data (if appropriate), and memory contents.
Exception data includes system and stack data at the time of the failure.
Failure data is not written to the log file.
A watchdog enhancement allows for the specification of which task failed in the event of a watchdog time-out.
There is a switchover in the case of a shutdown (redundant systems only) at which time the core file is created.

Initiating a Core Dump

Complete the following steps to initiate a core dump:

Step 1 Access the Maintenance Menu screen ("Accessing the Maintenance Menu Screen" section).

Step 2 Type K and press Enter.

The Core Dump options does not present you with a new screen. The Maintenance Menu screen remains displayed, and the "SHUTDOWN following Core Dump (Y/N)?" message appears at the bottom right of the screen (see Figure 5-22).

Figure 5-22: Maintenance Menu Screen—Core Dump Option Selected

Step 3 Complete one of the following options, which is dependent upon your needs:

To shut down the system after a core dump type Y and press Enter.

: The "ENTER To Confirm Core Reboot" message appears. Press Enter to confirm the shutdown.

To be keep the system in operation after a core dump type N and press Enter. This is the default option.

Note If you press Enter and do not indicate a SHUTDOWN option, the system remains in operation after a core dump.

The core file is generated after you press Enter in response to the "SHUTDOWN following Core Dump (Y/N)?" message.

The system automatically writes the core file to the C:/ directory. When a system is initialized, it checks to make certain there is enough disk space for the largest core file. If there is not enough space, a message is issued indicating a problem. Refer to Cisco VCO/4K System Messages for a description of messages related to the core dump feature.

When a core file is generated, the file is named core1. Note that core1 is the current core file. If an older core file already exists in the directory, the existing (older) file's name is increased by one and is saved with the new filename. For example, if a core1 file exists, the file is renamed to core2 and the new core file is named core1. If there is a core1 and a core2 file on the system, the core1 file is renamed core2, and the core2 file is renamed core3. The new core file is named core1. The system maintains up to four core files.

Sending a Core Dump File for Analysis

You may be asked to send a core dump file to Cisco for analysis. Use one of the following methods that to copy the file from the VCO/4K. A Cisco TAC representative can assist you with copying and sending the file to Cisco.

1. Use FTP, the Remote File Transfer feature, on your VCO/SDS system and transfer the file to a workstation. Refer to the "FTP Password Configuration" section for information on FTP.

2. Split the core dump (core1) file and copy the resulting file segments on to floppy disks, and mail them to Cisco Systems. Refer to the "Split File" section for more information on splitting files.

3. If you have the Ethernet option and NFS, mount the F: drive (the network drive) and move the file to the F: drive. After the file is on the network drive, use one of the following methods to send the file to Cisco:

A file transfer method with which you are familiar.
Contact a Cisco TAC representative to assist you.

Live Upgrade Control

Use the Live Upgrade Control option to update software on a redundant system without loss of calls, and with a minimum reduction in capacity. The process consists of converting the system controller to a new release, then switching over the port and service cards that need to be upgraded.

Refer to the Cisco VCO/4K Software Installation Guide for detailed information regarding the Live Upgrade procedure.
