Data commands apply to the setting up, configuring, and statistical reporting on data connections. For descriptions of the data commands on a FastPAD, refer to the FastPAD User's Guide. Examples of the tasks described in the chapter are:
The nodes and card sets to which the commands in this chapter apply are:
To set up a data connection:
| · cnfdclk | Specifies the clocking for the data channel |
| · cnfcldir | Sets the control leads for bidirectional pins 11 and 23 on an RS-232 data channel. The default is input |
| · tstport | Use sixth lead feature to provide test port loopback |
| · addyred | Enables optional card redundancy. This step requires extra hardware. |
| · cnfict | Configures an interface control template that determines output lead behavior for data channels. Output leads can be either configured as steady state (on or off) or programmed to follow an input lead. Five types of templates exist for channels in active, conditioned, looped, near, and far states. |
| · cpyict | Copies interface control template information from one channel to another. This step is optional. |
Step 2 Add the connection with the addcon command. The above configuration must have been completed at each end before the connection can be added.
You can configure redundant data channels by installing two identical card sets in adjacent slots and connecting the cards to the customer's line through a Y-cable. Applicable commands are"
Data channels have an associated default interface control template for each of the active (normal), conditioned, looped, near and far states. The templates define how the control leads at the data interface are to be configured (asserted, inhibited, follow a local source or follow a remote source). The interface control template can be changed by using the cnfict command. Each template and each control lead must be configured individually. The cpyict (copy interface control panel) can be used to apply (copy) the settings of a template for one data channel to those of a template for another data channel.
DFM (Data Frame Multiplexing) is a feature on the IPX and IGX 8400 series in which repetitive data patterns (such as IDLE codes) are suppressed at the source and regenerated at the remote node. This feature has the effect of approximately doubling the bandwidth of the data channel.
The command for changing the DFM enable-status for individual data channels is cnfchdfm. Before you execute this command, make sure the DFM feature has been activated on each applicable node by the Cisco WAN Switching Technical Response Team (TRT). You can check the DFM configuration for a channel by using the dspchcnf command. When the DFM feature is first activated at a node, it has the following default values:
The EIA feature encodes the status of the CTS or RTS lead as the eighth bit in each data byte. The byte subsequently is processed in accordance with the DFM algorithm, which remains unchanged.
Any DCE and DTE combination at each end is valid. A typical configuration might have the LDP at one end of a connection as DCE (normal clocking) and an LDM at the other end as DTE (looped clocking). RTS is transmitted in encoded form from the remote end to the local end, and CTS is transmitted in the other direction. Other EIA leads use the non-interleaved format.
The EIA feature is allowed for all legal baud rates 19.2 kbps and below and is activated by typing encoding type 7/8E followed by an *Z when adding a connection using the addcon command. Different channels on the same card may be set up with or without the feature, but all ports on the card must be configured at or below 19.2 kbps for EIA to be active. Note that you do not have to enter *Z after 7/8E on the command line because the system automatically enters it.
DDS Trunks normally operate at 56 Kbps. Cisco IPX and IGX 8400 series switches can provide a direct interface to a DDS line and provide limited distance access to Data Service Units (DSUs) by using the DDS format over private lines. The LDI4/DDS back card and LDP (Model B) or LDM front card support DDS. Each LDI/DDS supports four DDS trunks in DSU or OCU modes.

Establishes data channel connections between nodes in a network. After you add a connection using the addcon command, the node automatically routes the connection. The node where you execute addcon is the "owner" of the added connections. The concept of ownership is important because you must enter information about automatic rerouting and preferred routing at the node that owns the connection. See the cnfpref and cnfcos commands for more information on automatic rerouting. Before the node adds the connection, the proposed connection appears on the screen with a prompt for you to confirm the addition.
When applied to data connections, the addcon command adds a synchronous data connection to the network. You can add synchronous data connections to any node slot equipped with either an LDP or SDP card in an IPX or an LDM or HDM in an IGX 8400 series switch. Before you add a connection, determine the desired data rate. To find the data rates that individual cards support, refer to the card descriptions in the IGX 8400 Series Reference Manual or the IPX Reference Manual.
When connecting sets of data channels, you do not have to specify the full channel set for the local end of the connection. You have to designate only the first channel in the range. For example, to add connects 27.1-4 at local node alpha to channels 9.1-4 at beta, you can enter "addcon 27.1-4 beta 9.1". If Y-cable redundancy has been specified, you can add data connections at only primary card slots (not at the secondary card slots). See the addyred description for more information. Standard Data Connection RatesTable 8-2 lists the data rates. The following notations appear with some data rates:
· * | Must be used with 8/8 or 8/8I coding. |
· /n | Specifies a partially filled packet type: the /n allows partial packets to be sent and so avoid the delay incurred by waiting to build a full packet |
· f | Entered after the data rate, an f specifies "fast EIA" (interleaved EIA) for the connection. |
· t | Indicates "transparent" (CDP or CVM subrate DS0A): if you include the t-option, the IPX or IGX 8400 series switch does not check for supervisory or control information. |

In "fast EIA" signalling mode, an interleaved byte of EIA signalling information is associated with every byte of data in a packet. This format is appropriate for applications where EIA lead transitions must closely synchronize with user data. Fast EIA can apply to data rates up to 512 Kbps.
When user-data arrives with the 7/8 coding format, 7-bit bytes are used to build a packet. The user-data can have any format and can contain any pattern, including all "0"s. The single "1" inserted in the final bit position ensures that no more than seven consecutive "0"s occur in a byte. The 7/8 coding format is the safest mode to use when the data protocol is unknown.
When user-data arrives with the 8/8 coding format, 8-bit bytes are used to build a packet. The 8/8 coding format is more efficient than the 7/8 format, but the end-user equipment is responsible for meeting the T1 requirement of no more that 7 consecutive "0"s in a byte. If this requirement is not met, the IPX or IGX 8400 series switch inserts a "1" to invalidate the data. This mode can be used if the data or line protocol avoids long strings of zeros. An example line is a T1 trunk that uses B8ZS encoding.
When the arriving user-data has the 8/8I coding format, all 8 bits are used to form the bytes in a packet. The data is inverted so that 1s are changed to 0s, and 1s are changed to 0s. The end-user equipment must guard against data that contains over 7 consecutive "1"s in a byte, which (when inverted) would violate the T1 transmission requirement. This violation of the T1 transmission requirement would cause the IPX or IGX 8400 series switch to insert a "1" to invalidate the data. This format can be used for data protocols in which the idle codes are long strings of 0s, and the data bytes are scrambled.
If the data protocol requires an acknowledgment and is delay-sensitive avoid routing the connection over a satellite line (*s for avoid). If 8/8 or 8/8I coding is the selected format, Cisco suggests avoiding the use of trunks with zero code suppression (*z for avoid) because it could corrupt the last bit in the byte.

Enables or disables DFM for individual channels and sets the DFM parameters for the channels. The default state when the (purchased) DFM feature is activated on a card is enabled. Because DFM is a purchased option, the WANSwitching TRT must activate on the applicable nodes before you use the cnfchdfm command. The cards that support the use of cnfchdfm are the SDP and LDP on the IPX and the LDM and HDM on the IGX 8400 series switch.
The DFM feature must be both installed and enabled. The DFM feature must be installed through software control at each node terminating the connection. If DFM is not installed for a pertinent node in the network, the cnfchdfm command has no effect at that node. Furthermore, you must use cnfchdfm at both ends of the connection to enable DFM.

Sets the sampling rate for the updating EIA control leads. This rate can be set from 0 (no sampling) to 20 updates per second and defaults to 2 seconds. This rate governs the polling interval and packet generation rate for the EIA leads associated with the channel.
At 20 updates/sec, the control leads are polled for changes every 50 msec. Therefore, changes occurring more rapidly than that may not be detected. If there is no change in EIA lead status, no packet is sent. A minimum of one update per second is sent if the maximum update rate chosen is from 1 to 20. If the connection is configured in such a way that an implied isochronous clock is detected, the update rate is always 20/sec in the same direction as that of the clock signal. For 1.544 Mbps data connections, this defaults to 0.

Configures a CDP, CVM, or LDP or LDM DDS port interface type to OCU or DSU. When configuring DDS operations, this command returns an error if executed on a slot with an RS-232 back card. It forces a back card slot from RS-232 mode to DDS mode if a back card is not installed and there are no connections. Any Y-cable association is deleted in this case. The clocking tracks the DDS port interface type. OCU type interfaces are configured as "looped", and DSU type interfaces are configured as "normal". The default interface is "DSU".
When configuring CDP or CVM operation, this command configures DCE types as "normal" clocking and DTE types as "looped" clocking. The default type is DCE. For T1 lines, DS0A on T1 unassigned signalling is configurable. When a connection is not present, voice channels are converted to data channels.

Configures the clocking for a data channel. In general, the clock configuration may be normal, split, or looped for an SDP or HDM (fewer options for an LDP or LDM). The clock configuration of each channel of a connection determines how the clock will be propagated through the network, and how external equipment should be synchronized.
If clocking is not set correctly, there may be no synchronization, and the connection will operate in a plesiochronous mode. Each data port can be configured independently to act as either DCE or DTE by adjusting the jumper (SDI card) or changing the adapter cable (LDI card) on the data interface card. The effect of the clocking type designated depends on whether each data port is configured as DTE or DCE. The following data clocking configurations are possible with the cnfdclk command:
When the data port is configured as DCE, selecting a clocking type of "n" (for normal) results in clocking as illustrated below. The IPX or IGX 8400 series switch, acting as DCE, provides both the transmit and receive data clocks to the user equipment.
When the data port is configured as DCE, selecting a clocking type of "s" (for split) results in clocking as illustrated below. In "split" clocking, TT may be generated independently of RxC. The maximum data rate for split clocking is 112 kbps.
When the data port is configured as DCE, selecting a clocking type of "l" (for looped) results in clocking as illustrated below. The "Terminal Timing" signal, called TT or XTC, is simply RxC looped back from the user equipment. In this configuration, it is important that the two clocks (RxC and TT) be frequency locked. This clocking configuration is supported for all data rates.
When the data port is configured as DTE, selecting a clocking type of "n" (for normal) results in clocking as illustrated below. The IPX, acting as DTE, receives both the transmit and receive data clocks from the user equipment. When the user equipment is not referenced to the network clock, the maximum data rate for this configuration is 112 kbps. The two clocks must be frequency-locked for proper operation.
When the data port is configured as DTE, selecting a clocking type of "s" (for split) results in the clocking as illustrated below. When the user equipment is not referenced to the network clock, the maximum data rate for this configuration is 112 kbps. The two clocks must be frequency-locked for proper operation.
If you specify clocking type of "l" (looped) when the data port is in DTE mode, the result is the clocking arrangement shown in Figure 8-6 . The RxC clock signal is the TT(XTC) signal looped back to the IPX or IGX 8400 series by the user equipment. The network supports this clocking configuration for all data rates. The restrictions to the data clocking schemes are:

Sets the interface control template signals. The signals that can be set using cnfict depend on the type of back card used and whether the hardware is configured for DCE or DTE. On an IPX, the applicable front cards are the SDP, LDP, FRP, CDP (for data), and FTC (for data). On an IGX 8400 series, the applicable front cards are the LDM, HDM, FRM, CVM (for data), and FTM (for data). Each data channel has a default interface control template for its active, conditioned, and looped near and far states. The cnfict command is used to change a control template. Each interface control lead in each template is individually configured.
When Y-cable redundancy is in effect, the control template configuration for the data channels terminating at the primary slot is also applied to the data channels of the secondary slot. Any configuration information for the secondary slot is ignored. The list below shows the configurable leads. The leads are configurable for each type of data interface supported by the IPX or IGX 8400 series switch. The entries under the "IPX/IGX Name" column indicate the abbreviations to use when specifying input or output leads on the command line. The leads listed below show the equivalence between RS-232C, RS-232D, RS-449,V.35, and X.21 interfaces. The IPX treats leads impartially for non-interleaved connections. Any signal received on an EIA pin at one end may be transmitted to any pin at the other end, up to the maximum of 12 EIA leads on any interface type. For interleaved EIA connections, refer to the "Fast EIA" column. The column shows which leads are carried in the interleaved bytes in the data packets. All remaining leads are carried in standard control lead packets.

Note that pins 11 and 23 on an RS-232 port are bi-directional, and their default direction is input. See the cnfcldir command for information on changing the direction of these pins. The cpyict command can be used to copy an interface control template from one data channel to another. It can then be edited using the cnfict command. The dspbob command displays the state of leads at specified intervals.

Parameter | Description | |||
---|---|---|---|---|
port | Specifies the data channel or frame relay port whose interface control template is to be configured. Entered as <slot.port>. On an IPX, the applicable cards are the SDP, LDP, FRP, CDP, and FTC. On an IGX 8400 series switch, the applicable cards are the LDM, HDM, FRM, CVM, and FTM. | |||
template | Specifies which interface control template to configure for the channel and has the format <a/c/l/n/f>. Valid entries are listed below: The only valid template for a frame relay port, X.21 or V.35, is the ACTIVE template. Also, all the output leads have steady state values and do not follow local or remote inputs | |||
| Entry | Template | Description |
|
| a | Active | The "active" control template is in effect while the data channel is active (normal operation) i.e. when the connection is routed and not failed. | |
| c | Conditioned | The "conditioned" control template is in effect when conditioning is applied to the data channel. The conditioned template is used when the network detects that it cannot maintain the connection because of card failures or lack of bandwidth (The connection is failed.) | |
| l | Looped | The "looped" template is in effect when the data channel is being looped back in either direction. The looped template is used when addloclp or addrmtlp has been used to loop the connection within the network. | |
| n | Near loopback | The "near" template is in effect when running a tstport n or an addextlp n on a port. The port is configured such that the external near modem is placed in a loopback. | |
| f | Far loopback | The "far" template is in effect when running a tstport f or an addextlp f on a port. The port is configured such that the external far-end modem is placed in a loopback. | |
output | Specifies the output lead to configure. Refer to the Configurable Lead information in the command description for valid abbreviations. Configurable output leads vary depending on the type of data interface: RS-232, V.35, X.21, or RS-449. | |||
source | Specifies how the lead is to be configured and has the format | |||
| Source Options |
|
| |
| on | The output lead is asserted. | ||
| off | The output lead is inhibited. | ||
| l | (for local) indicates that the output follows a local lead. | ||
| r | (for remote) indicates that the output follows a remote lead. | ||
| input | The name of the local or remote input lead that the output lead follows. | ||
| delay | The time in milliseconds that separates the "off" to "on" lead transitions. Delay is valid only when the output lead is CTS and the input lead is local RTS. "On" to "Off" lead transitions are not subject to this delay. |
Copies all control template information associated with a given channel: the active template information, the conditioned template information, and the looped template information for near and far ends. Once copied, the control template information may be edited with the cnfict command. See the cnfict command for more information on interface control templates.
On an IPX, the applicable front cards are the SDP, LDP, FRP, CDP (for data), and FTC (for data). On an IGX 8400 series switch, the applicable front cards are the LDM, HDM, FRM, CVM (for data), and FTM (for data).

Removes connections from the network. After entry of the channel or range of channels to delete, a prompt requests confirmation of the selection. Connections can be deleted from the node at either end of the connection. Do not delete a connection when the node at the other end of the connection is unreachable. The unreachable node does not recognize the deletion. It is especially important not to delete a connection to an unreachable node and then connect that channel to another node.
