Adding DS1/E1 Lines

This procedure explains how to add DS1/E1 lines to BSC or NSC cards. NSCs support either T1 or E1 lines, but the whole chassis must be configured for one mode or the other. DS1 channels within a DS3 line have the following mapping:

DS 3 Line Number DS1 Line Number

501

1-28

502

29-56

503

57-84

504

85-112

505

113-140

506

141-168

Note   Before adding DS1 lines to a DS3 line, ensure the corresponding DS3 line exists.

To add DS1/E1 lines, follow these steps:

Step 1   Enter the addds1ln command and optional parameters (see "addds1ln" section.

The following example adds two DS1 lines with AMI line coding at slot 11 lines 6 and 7:

addds1ln 11.6 2 # 5

This example assumes the chassis is configured for T1 lines and that DS3 line number 501 already exists in slot 11.

Note   The system stops adding lines on the first failure, even if later additions are valid.

Step 2   Add other DS1/E1 lines, as required.

Step 3   Verify the configuration for the new lines using the lsds1ln command, specifying the logical number of the slot in the MGX 8260 chassis and the number of the DS1/E1 line, delimited by a period (slot.line). The display identifies the associated DS3 line, if appropriate.

Changing DS1/E1 Lines

Warning Changing a DS1/E1 line interrupts service. Perform this operation during light traffic periods or in a pre-arranged maintenance window.

To change the configuration of a DS1/E1 line, enter the chds1ln command and optional parameters. Unspecified parameters, designated by a # symbol, retain their current settings.

For example, the following command activates a local diagnosis loopback on line 6 of logical slot 11:

chds1ln 11.6 # # # # 4

Deleting DS1/E1 Lines

Warning Deleting a DS1/E1 line interrupts service. Perform this operation during light traffic periods or in a pre-arranged maintenance window.

To delete a DS1/E1 line, enter the delds1ln command, specifying the slot.line and number of lines.

The system deactivates the DS1/E1 line and removes its configuration from the database.

Note   The MGX 8260 inhibits deletion of a line with an active connection.

The following example deletes 2 DS1 lines beginning at line 6 of slot 11:

delds1ln 11.6 2

Configuring DS3 Lines

From the command line interface, you can add, change, delete, and view DS3 lines. These procedures apply to all DS3 lines, regardless of the card type.

Viewing DS3 Configuration and Status

To view detail information for a single DS3 line, enter the lsds3ln command, specifying the location (slot.line) of the DS3 line.

The system displays all DS3 settings for the specified line:

======================================================================= DS3 Line Entry (lsds3ln) ======================================================================= DS3 Line : 16.501 Line Type : dsx3M23 Line Coding : dsx3B3ZS Send Code : dsx3SendNoCode Line Status : 464 Time Elapsed : 12 Valid Intervals : 0 Cable Length : 1 Transmit Clock Source : localTiming Circuit Identifier : PMC-PM8313-D3MX Alarm : Yes Rcv RAI Failure : No Xmit RAI Failure : Yes Rcv AIS : No Transmit AIS : No Loss of Frame : Yes Loss of Signal : Yes Loopback State : No Rcv Test Code : No Other Failure : No LED Status : Solid RED

Adding DS3 Lines

When adding DS3 lines that contain DS1 channels, add the DS3 lines first.

To add DS3 lines, follow these steps:

Step 1   Enter the addds3ln command (see "addds3ln" section).

The following example adds two new DS3 lines with default settings to slot 11 lines 501 and 502:

addds3ln 11.501 2
Note   The system stops adding lines on the first failure.

Step 2   Add other DS3 lines, as necessary.

Step 3   Check the configuration, using the lsds3ln command, specifying the location (slot.line) of the new line.

Changing DS3 Lines

Warning Changing a DS3 line interrupts service. Perform this operation during light traffic periods or in a pre-arranged maintenance window.

To change the settings of a DS3 line, enter the chds3ln command as described in the "chds3ln" section.

For example, to activate a line loopback on DS3 line 501 in logical slot 11:

chds3ln 11.501 # # # # 3

Deleting DS3 Lines

To delete a DS3 line, enter the delds3ln command, specifying the logical number slot and line number (slot.line), and the number of lines to delete. Valid slot values: 7 or 8 for the DMC card; 11 -16 for the BSC card. Valid line values are 1-6.

The system deactivates the DS3 line and removes its configuration from the database.

The following example deletes two DS3 lines beginning at line 501 in slot 11:

delds3ln 11.501 2

Mapping DMC Lines

The DMC maps source DS1 channels from the DS3 interface to destination DS1 channels on the NSC. The mapping is one-to-one and can connect any source DS1 to any destination DS1 (see Figure 4-1).


Figure 4-1: Example of DS3 to DS1 Mapping from DMC to NSC


A single DS3 can map to multiple NSCs or multiple DS3s can map to a single NSC. Map definitions can be organized or arbitrary, but often occur in contiguous groups because you can define a range of mappings with a single command. The MGX 8260 Media Gateway stores map definitions in a map table, as follows:


Table 4-1: DMC Map Table
Source DS3 Line Source DS1 Line Destination NSC Slot Destination DS1 Line

You can initialize or alter the map table from any of the management interfaces or from the command line. This section describes how to add, change, or delete entries from the command line.

Adding Map Table Entries

You can add map entries individually or within a range. When adding individual map entries, the following restrictions apply:

You simplify the process of mapping DS3 to DS1 lines by mapping a range of DS1s rather than individual lines. A map range is added in a sequential and contiguous manner, and can cross either source or destination boundaries.

The entire range of source and destination lines must be contiguous. The system stops mapping lines if it encounters a source or destination that is already assigned, leaving map pairs before the contiguous break assigned and the rest unassigned.

To add map table entries, enter the addm13 command as described in the "addm13" section.

For example, in an MGX 8260 Media Gateway without any existing mapping, specify the maximum number of mappings as follows:

addm13 1 1 1 1 168

To add three map entries, enter the following command:

addm13 1 3 1 1 3

This example creates the following map table:

Changing Map Tables

You change map table entries one at a time. A change removes an existing mapping and replaces it with a map between the old source and new destination. To apply a change, the following must be true:

Changing a map entry interrupts service to a large number of subscribers. Perform this task on inactive lines or during light traffic periods.

To change an existing map entry, enter the chm13 command. For example the following command sequence adds three map table entries and then changes one of them:

addm13 1 3 1 1 3 chm13 1 3 1 4

The example creates the following map table:

Deleting Map Table Entries

You can delete map table entries individually or in a range. When deleting a range of entries, the entire number of source and destination lines should be contiguous. The system stops deleting lines if it encounters a break in source range, deleting only those lines before the break.

Deleting map entries discontinues or interrupts service to a large number of subscribers. Perform this task only on lines that are out of service.

To delete map table entries, enter the delm13 command. The following example deletes three sequential map table entries, starting at DS3 line 1, DS1 line 1:

delm13 1 1 3

Viewing Map Tables

You can view the map table for the system as a whole or for individual source DS1 lines.

To view map tables for a single source DS1, enter the lsm13 command, specifying the number of the source DS3 line and number of the DS1 line within the DS3 line. Valid entries are 1 through 6 for the DS3 and 1 through 28 for the DS1.The system lists map table entries for the specified line.

To view all DS3 to DS1 mappings, enter the lsm13s command. The system lists all map table entries:

================================================================== DMC T3-T1 Mapping Entries (lsm13s) ================================================================== Src T3 Line Src T1 Line Dst Slot Dst T1 Line ============= ============= ============= ================ 1 3 1 1 1 4 1 4 1 5 1 3

Configuring Fast Ethernet Lines

The SCC has four Fast Ethernet lines. This section explains how to configure and manage these lines.

Adding a Fast Ethernet Line

To add a Fast Ethernet line, follow these steps:

Step 1   Enter the addethln command as described in the "addethln" section.

The following example adds a Fast Ethernet line to slot 9 line 2 with an IP address of 10.15.26.98, a gateway of 10.15.26.1, a target state of active, RDP disabled, a subnet mask of 255.255.255.0, and full duplex mode:

addethln 9.2 10.15.26.98 10.15.26.1 1 1 255.255.255.0 2

Step 2   Add other Fast Ethernet lines, as necessary.

Step 3   Verify the configuration using the lsethlns command.

The system displays the line configuration.

Changing a Fast Ethernet Line

Warning Changing a Fast Ethernet line interrupts service to a large number of users. Perform this operation during light traffic periods or in a pre-arranged maintenance window.

To change the configuration of a Fast Ethernet line, enter the chethln command as described in the "chethln" section. For example, the following command enables RDP but leaves other parameters unchanged on Fast Ethernet line 1 in slot 9:

chethln 9.1 # 2

The system enables RDP on the specified line.

Deleting Fast Ethernet Lines

To delete Fast Ethernet lines, enter the delethln command, specifying the slot and line number of the SCC. Valid values for the slot number of the SCC are either 9 or 10. Valid values for the Fast Ethernet line is a number from 1 to 4.

The following example deletes Fast Ethernet line 1 in slot 9:

delethln 9.1

Setting the Fast Ethernet Administrative Status

To enable a Fast Ethernet, enter the upethln command, specifying the slot and line number of the SCC (slot.line). The system enables the Ethernet line. The corresponding front panel ACT LED changes to green.

The following example enables Fast Ethernet line 1 in slot 9:

upethln 9.1

To disable the a Fast Ethernet, enter the dnethln command, specifying the slot and line number of the SCC (slot.line). The system disables the Ethernet line. The corresponding front panel ACT LED changes to red.

The following example disables Fast Ethernet line 1 in slot 9:

dnethln 9.1

Configuring Static Routes

You can configure static routes for the MGX 8260 routing table. These routes apply to lines that utilize an IP network. You can configure static routes for empty slots or non-existing lines, but the changes have no effect without the necessary hardware.

Adding Static Routes

To add a static route, enter the addsrt command, as described in the "addsrt" section. The system adds the static route to the routing table.

Deleting Static Routes

To delete a static route, enter the delsrt command, specifying the IP address of the static route you want to delete and the slot and line number (slot.line) for the static route interface. The system deletes the static route from the routing table.

Viewing Static Routes

To view a specific static route, enter the lssrt command, specifying the IP address of the static route and the slot and line number (slot.line) for the static route interface. The system displays the static route information:

Configuring OC-3 Lines

The OC-3 SCC and back card supports four OC-3 lines. This section explains how to configure and manage these lines.

Multi-chassis Considerations

In a multi-chassis application, each MGX8260 needs a common reference clock for all TDM lines. You can accomplish this by synchronizing the clocks of each chassis to the common ATM switch clock (See Figure 4-2).


Figure 4-2: Multi-chassis Timing


To synchronize clocks, follow these steps:

Step 1   Set the primary clock source for each chassis to an OC-3 line. Use the chpcklsrc command for this purpose.

Step 2   Set the clock source for DS3 and DS1 lines to local using the chds3ln or chds1ln commands. This is the default configuration for these lines.

Viewing OC-3 Configuration and Status

To view information for a single OC-3 line, enter the lssonetln command, specifying the slot and line number of the SCC (slot.line).

Adding OC-3 Lines

To add OC-3 lines, follow these steps:

Step 1   Add one or more lines using the addsonetln command. Optionally, customize the line using the command line arguments. See the "addsonetln" section.

The following example adds one line to slot 9 line 1 with default parameters:

addsonetln 9.1

Step 2   Verify the configuration using the lssonetln command.

Changing OC-3 Lines

Warning Changing an OC-3 line interrupts service to a large number of users. Perform this operation during light traffic periods or in a pre-arranged maintenance window.

To change OC-3 lines, follow these steps:

Step 1   Change SONET lines using the chsonetln command, specifying the parameters to change. See the "chsonetln" section.

For example, the following command enables Payload Scrambling but leaves other parameters unchanged on OC-3 line 1 in slot 9:

chsonetln 9.1 # # # # # 2

Step 2   Verify the configuration using the lssonetln command.

Deleting OC-3 Lines

To delete OC-3 lines, enter the delsonetln command, specifying the slot and line number of the SCC. Valid values for the slot number of the SCC are either 9 or 10. Valid values for the OC-3 line is a number from 1 to 4.

The following example deletes OC-3 line 1 in slot 9:

delsonetln 9.1

Viewing E-RDI Configuration and Status

Understanding E-RDI and Trace Parameters

Path and trace labels help identify particular SONET line. The trace label is a text string carried in a 16-byte or 32-byte message carried in the SONET overhead. The system alters or reserves some of the bytes for synchronization or other purposes.

Using 16-Byte Messages

When using 16-byte messages, consider the following points:

Using 64-Byte Messages
Forming Hex Messages

You use two hexidecimal numbers to represent each ASCII character in a trace message. For example, you represent an ASCII space with the hex pair 20. The following table shows a few additional examples.

Trace Message Hex String

The system takes the following actions on error on bad hex strings:

Configuring E-RDI and SONET Trace

To change E-RDI parameters, follow these steps:

Step 1   Change extended rdi parameters for SONET lines using the chsonetperdi command, specifying the location and E-RDI parameters. See the "chsonetperdi" section.

Step 2   Change path trace parameters for SONET lines using the chsonettrace command, specifying the location and path trace parameters. See the "chsonettrace" section.

Step 3   Change expected path trace parameters for SONET lines using the chsonetexptrace command, specifying the location and path trace parameters. See the "chsonetexptrace" section.

Configuration Tasks for Ports

See the following sections for port configuration tasks.

Configuring Voice Ports

Voice ports use voice over IP or ATM. The MGX 8260 Media Gateway identifies a voice port by a logical port number that is independent of the port's physical location. The following parameters describe the physical location:

When you add or change a voice port, you associate a logical port number with these physical descriptors.

Adding Voice Ports

To add a voice port, enter the addvport command as described in the "addvport" section. For example, to add logical voice port 4 using DS0 4 of DS1 line 1 in slot 13, type the following command:

addvport 13 4 1 4 1

Changing Voice Ports

You can change any of the optional parameters for an existing port. To change a voice port, use the chvport command, specifying the same parameters as required to add a voice port. For example, to change the echo tail while leaving other parameters unchanged, type the following command:

chvport 13 1 # # # # # 2

The system changes the echo tail for logical port 1 in slot 13 to tail24ms.

Deleting Voice Ports

To delete a voice port, enter the delvport command, specifying the logical slot number of an NSC and the logical port number for an existing voice port. For example, this command deletes port 4 of slot 13.

delvport 13 4

About the Announcement Service

The MGX 8260 Media Gateway can store and play announcement messages when configured for the IPDC call control protocol. This service is useful when informing callers about a telephone number change or other voice messages. The system can store up to 100 announcement files, with a total play duration of 30 minutes.

File Encoding

The MGX 8260 Media Gateway supports the following encoding formats:

File Types

The MGX 8260 Media Gateway supports the following file types:

File Names

The Announcement Service uses a file identifier that it learns from the name you assign. Construct the file name as follows:

fileName_ID.ext

The file name is the alphanumeric string before the underscore and the file identifier is the number after the underscore. The id is a number from 1 to 100 and the file extension is either au or wav. The file name can contain up to 20 characters total.

Configuration Tasks for Announcement Services

See the following sections for Announcement Service configuration:

Adding and Activating an Announcement

To add and activate an announcement, follow this procedure:

Step 1   Download the announcement message using tftp.

tftp ipAddress bin put sourceFile announceFile

Step 2   Activate the message using the acannfile command, identifying the file by ID rather than by name. You can view file IDs using the lsannfiles command.

Step 3   The system copies the file from the download location on the SCC to all NSCs in the chassis.

Deactivating and Removing an Announcement

To deactivate and remove an announcement, follow this procedure.

Step 1   Deactivate the file using the deacannfile command, specifying the file ID. You can view file IDs using the lsannfiles command.

Step 2   Optionally, remove the file using the rmannfile command, specifying the file ID. Since the system has limited file capacity, you should remove announcements you no longer plan to use.
