A circuit line is the physical line that carries frame relay, data, voice, or ATM traffic between customer equipment and an IPX, IGX, or BPX node. Each piece of customer premises equipment is attached to a node through a circuit line. After a card has been "upped" with the upcd command, a circuit line on that card can be "upped" and configured.
This chapter:
The following table shows the permissible card combinations for CPE-to-IPX and IGX lines.

Frame relay, data, and voice connections require an active line. Use the commands in the following steps to establish a line. The card must be in either the active or standby state before you enter these commands.
Step 1 Use upln to activate a circuit line in a slot that contains the appropriate circuit line card set.
Step 2 Use cnfln to configure the circuit line.
The upln and cnfln commands establish the general parameters for the line but do not establish specific frame relay, data, or voice parameters. Refer to applicable chapters for details on a particular service. For example, "Data Connections" describes specific commands for data connections, and "Frame Relay Connections" describes specific commands for frame relay connections.
The following describes related commands.
Figure 5-1, Figure 5-2, Figure 5-3, Figure 5-4, and Figure 5-5 show the command sequence for setting up lines for voice, serial data, frame relay, ATM, and FastPADs, respectively. A yes/no decision branch for "Other Side?" and the vt command in the sequence indicates command sequences on local and far nodes. "Multiplex" refers to channelized streams.
Table 5-3 shows the full command name and starting page for each line command description.

Configures a UVM to convert channel associated signaling (CAS) and dual-tone multi-frequency (DTMF) tones to common channel signaling (CCS) call control messages. This conversion is necessary for voice networks in which a Voice Network Switch (VNS) uses SVCs to route calls from a CAS-based PBX through a WAN. Model B or later firmware on the UVM is necessary.
Before you can execute cnfcassw, note the following:

Configures a line to be compatible with the device to which it connects. The cnfln command applies to voice, data, frame relay, and ATM lines. See Table 5-2 for a list of the front and matching back cards. Because of the variety of line types and characteristics, the parameters section of this description has three tables to describe the parameters. The system automatically presents the correct options on the command line for each line type. If a parameter is not applicable to a card type, the system displays the parameter in half-tone or the value field of that parameter with dashed lines. Table 5-5 describes the parameters for voice, data, and frame relay parameters. Table 5-6 describes the parameters for the ATM Line Module (ALM/A). Table 5-7 describes the parameters for the ASI line card (BPX node). Table 5-8 describes the ATM parameters for the UXM card (IGX node).
For an ALM/A, the cnfln command lets you configure the receive rate and header type and enable payload scrambling. For more details on the features and configurable parameters of the ALM/A, refer to the Cisco IGX 8400 Series Reference and the Cisco IGX 8400 Series Installation manuals. Note that, although the cnfln display shows the transmit rate, you cannot configure it because the ALM/A transmit rate is always the maximum line rate.

Parameter | Description |
---|---|
slot.port | Specifies the BXM card slot and port number. |
Maximum PVC Channels | The maximum number of LCNs allocated for AutoRoute PVCs for this port. The range is 1 to 256. 256 is the default. For trunks, there are additional LCNs allocated for AutoRoute that are not configurable. You can use the dspcd <slot> command to display the maximum number of LCNs configurable by using the cnfrsrc command for the given port. For trunks, "configurable LCNs" represent the LCNs remaining after the BCC has subtracted the "additional LCNs" needed. For a port card, a larger number is shown, as compared with a trunk card. Setting this field to "0" would enable configuring all of the configurable LCNs to the VSI. Note that you must specify a value greater than 0 for the Maximum PVC Channels, Maximum PVC Bandwidth, and Maximum VSI LCNs parameters. Otherwise, you will not be able to create more than two PVCs on a BXM card. Also, if these parameters do not have values greater than 0, you will be unable to change the connection channel amount when you configure the BXM trunk using cnftrk. |
Maximum PVC Bandwidth | Specifies the maximum bandwidth of the port allocated for AutoRoute use. The range is 0 to 352207. 0 is the default. Note that you must specify a value greater than 0 for the Maximum PVC Channels, Maximum PVC Bandwidth, and Maximum VSI LCNs parameters. Otherwise, you will not be able to create more than two PVCs on a BXM card. Also, if these parameters do not have values greater than 0, you will be unable to change the connection channel amount when you configure the BXM trunk using cnftrk. |
Configure Partition | Answer yes or no to begin configuring resources for the partition. |
Partition ID | Specifies the ID number of the partition. The range is 0 to 255. 0 is the default. Always use 0 in Release 9.1. |
Enable Partition | Answer yes or no to enable your configured partition. |
Minimum VSI LCNs | The minimum number of LCNs guaranteed for this partition. The range is 1 to 256. 0 is the default.The VSI controller guarantees at least this many connection endpoints in the partition, provided there are sufficient free LCNs in the common pool to satisfy the request at the time the partition is added. When a new partition is added or the value is increased, it may be that existing connections have depleted the common pool so that there are not enough free LCNs to satisfy the request. The BXM gives priority to the request when LCNs are freed. The net effect is that the partition may not receive all the guaranteed LCNs (min LCNs) until other LCNs are returned to the common pool. You may not increase this value dynamically. However, this may cause the "deficit" condition described above. The command line interface warns the user when the action is invalid, except for the "deficit" condition. To avoid this deficit condition, which could occur with maximum LCN usage by a partition or partitions, it is recommended that all partitions be configured ahead of time before adding connections. Also, it is recommended that all partitions be configured before adding a VSI controller using the addshelf command. |
Maximum VSI LCNs | The total number of LCNs the partition is allowed for setting up connections. The minimum VSI LCNs is included in this calculation. If maximum LCNs equals minimum LCNs, then the maximum VSI LCNs are guaranteed for this partition. Otherwise, (max - min) LCNs are allocated from the common pool on a FIFO basis. If the common pool is exhausted, new connection setup requests will be rejected for the partition, even though the maximum LCNs has not been reached. You may increase this value dynamically when there are enough unallocated LCNs in the port group to satisfy the increase. You may not decrease the value dynamically. All partitions in the same port group must be deleted first and reconfigured in order to reduce this value. Different types of BXM cards support different maximum values. If you enter a value greater than the allowed maximum, a message is displayed with the allowable maximum value. Note that you must specify a value greater than 0 for the Maximum VSI LCNs, Maximum PVC Channels, and Maximum PVC Bandwidth parameters. Otherwise, you will not be able to create more than two PVCs on a BXM card. Also, if these parameters do not have values greater than 0, you will be unable to change the connection channel amount when you configure the BXM trunk using cnftrk. |
Start VSI VPI | By default the TSC (for example, the 7200 or 7500 series router) will use either a starting VSI VPI of 1 or 2 for tag switching, whichever is available. If both are available, a starting VSI VPI of 1 is used. The VPI range should be 2-15 on a BPX 8260 VSI. The VSI range for tag switching on the BPX 8620 is configured as a VSI partition, usually VSI partition number 1. VSI VPI 1 is reserved for AutoRoute PVCs, so the VSI partition for tag switching should start at VPI 2. If VPI 2 is not to be used, the tag switching VPI interface configuration command can be used on the TSC to override the defaults. The range is 2 to 4095. Always set to 2 for trunks. |
End VSI VPI | Two VPIs are sufficient for Release 9.1, although it may be advisable to reserve a larger range of VPIs for later expansion, for example, VPIs 2-15. The range is 2 to 4095. |
Minimum VSI Bandwidth | The minimum port bandwidth allocated to this partition in cells/sec. (Multiply by 400 based on 55 bytes per ATM cell to get approximate bits/sec.) The range is 0 to 352207. 0 is the default. |
Maximum VSI Bandwidth | The maximum port bandwidth allocated to this partition. This value is used for VSI QBIN bandwidth scaling. The range is 0 to 352207. 0 is the default. |

Next Command:
Use the dsptsmap command to display the channel to timeslot mapping usage information on a UVM card on an IGX node or a CDP/CVM card on an IPX node. The dsptsmap command is for use with the SVC caching feature which speeds up call setup for most VNS controlled calls. The SVC caching feature avoids some of the call setup/tear-down operations associated with addcon and delcon as a call originates or terminates. The SVC caching feature reduces the connect time for many switch calls over a busy network.
To use the dsptsmap command, the line must have SVC caching enabled on it. You can find out if a channel is disabled by using the dsptsmap command.
The cnfln command is used to configure the SVC caching parameter setting.
The dspcons command is used to view disabled connections provided the SVC has not been deleted.
The dsplncnf command will show the value (On/Off) of the SVC caching mode feature.
Refer to the VNS Installation and Configuration Manual for more information on SVC caching.

A circuit line is the physical line that carries data, voice, frame relay, or ATM traffic between an IPX, IGX, or BPX node and customer premises equipment (CPE). Each piece of customer premises equipment is attached to a node through a circuit line. After a card has been "upped" with the upcd command, a circuit line on that card can be "upped" and configured.

Frame relay, data, and voice connections require an active line. Use the commands in the following steps to establish a line. The card must be in either the active or standby state before you enter these commands.
Step 1 Use upln to activate a circuit line in a slot that contains the appropriate circuit line card set.
Step 2 Use cnfln to configure the circuit line.
The upln and cnfln commands establish the general parameters for the line but do not establish specific frame relay, data, or voice parameters. Refer to applicable chapters for details on a particular service. For example, "Data Connections" describes specific commands for data connections, and "Frame Relay Connections" describes specific commands for frame relay connections.
The following describes related commands.
Figure 5-1, Figure 5-2, Figure 5-3, Figure 5-4, and Figure 5-5 show the command sequence for setting up lines for voice, serial data, frame relay, ATM, and FastPADs, respectively. A yes/no decision branch for "Other Side?" and the vt command in the sequence indicates command sequences on local and far nodes. "Multiplex" refers to channelized streams.

Configures a line to be compatible with the device to which it connects. The cnfln command applies to voice, data, frame relay, and ATM lines. See Table 5-2 for a list of the front and matching back cards. Because of the variety of line types and characteristics, the parameters section of this description has three tables to describe the parameters. The system automatically presents the correct options on the command line for each line type. If a parameter is not applicable to a card type, the system displays the parameter in half-tone or the value field of that parameter with dashed lines. Table 5-5 describes the parameters for voice, data, and frame relay parameters. Table 5-6 describes the parameters for the ATM Line Module (ALM/A). Table 5-7 describes the parameters for the ASI line card (BPX node). Table 5-8 describes the ATM parameters for the UXM card (IGX node).
For an ALM/A, the cnfln command lets you configure the receive rate and header type and enable payload scrambling. For more details on the features and configurable parameters of the ALM/A, refer to the Cisco IGX 8400 Series Reference and the Cisco IGX 8400 Series Installation manuals. Note that, although the cnfln display shows the transmit rate, you cannot configure it because the ALM/A transmit rate is always the maximum line rate.

Parameter | Description |
---|---|
slot.port | Specifies the BXM card slot and port number. |
Maximum PVC Channels | The maximum number of LCNs allocated for AutoRoute PVCs for this port. The range is 1 to 256. 256 is the default. For trunks, there are additional LCNs allocated for AutoRoute that are not configurable. You can use the dspcd <slot> command to display the maximum number of LCNs configurable by using the cnfrsrc command for the given port. For trunks, "configurable LCNs" represent the LCNs remaining after the BCC has subtracted the "additional LCNs" needed. For a port card, a larger number is shown, as compared with a trunk card. Setting this field to "0" would enable configuring all of the configurable LCNs to the VSI. Note that you must specify a value greater than 0 for the Maximum PVC Channels, Maximum PVC Bandwidth, and Maximum VSI LCNs parameters. Otherwise, you will not be able to create more than two PVCs on a BXM card. Also, if these parameters do not have values greater than 0, you will be unable to change the connection channel amount when you configure the BXM trunk using cnftrk. |
Maximum PVC Bandwidth | Specifies the maximum bandwidth of the port allocated for AutoRoute use. The range is 0 to 352207. 0 is the default. Note that you must specify a value greater than 0 for the Maximum PVC Channels, Maximum PVC Bandwidth, and Maximum VSI LCNs parameters. Otherwise, you will not be able to create more than two PVCs on a BXM card. Also, if these parameters do not have values greater than 0, you will be unable to change the connection channel amount when you configure the BXM trunk using cnftrk. |
Configure Partition | Answer yes or no to begin configuring resources for the partition. |
Partition ID | Specifies the ID number of the partition. The range is 0 to 255. 0 is the default. Always use 0 in Release 9.1. |
Enable Partition | Answer yes or no to enable your configured partition. |
Minimum VSI LCNs | The minimum number of LCNs guaranteed for this partition. The range is 1 to 256. 0 is the default.The VSI controller guarantees at least this many connection endpoints in the partition, provided there are sufficient free LCNs in the common pool to satisfy the request at the time the partition is added. When a new partition is added or the value is increased, it may be that existing connections have depleted the common pool so that there are not enough free LCNs to satisfy the request. The BXM gives priority to the request when LCNs are freed. The net effect is that the partition may not receive all the guaranteed LCNs (min LCNs) until other LCNs are returned to the common pool. You may not increase this value dynamically. However, this may cause the "deficit" condition described above. The command line interface warns the user when the action is invalid, except for the "deficit" condition. To avoid this deficit condition, which could occur with maximum LCN usage by a partition or partitions, it is recommended that all partitions be configured ahead of time before adding connections. Also, it is recommended that all partitions be configured before adding a VSI controller using the addshelf command. |
Maximum VSI LCNs | The total number of LCNs the partition is allowed for setting up connections. The minimum VSI LCNs is included in this calculation. If maximum LCNs equals minimum LCNs, then the maximum VSI LCNs are guaranteed for this partition. Otherwise, (max - min) LCNs are allocated from the common pool on a FIFO basis. If the common pool is exhausted, new connection setup requests will be rejected for the partition, even though the maximum LCNs has not been reached. You may increase this value dynamically when there are enough unallocated LCNs in the port group to satisfy the increase. You may not decrease the value dynamically. All partitions in the same port group must be deleted first and reconfigured in order to reduce this value. Different types of BXM cards support different maximum values. If you enter a value greater than the allowed maximum, a message is displayed with the allowable maximum value. Note that you must specify a value greater than 0 for the Maximum VSI LCNs, Maximum PVC Channels, and Maximum PVC Bandwidth parameters. Otherwise, you will not be able to create more than two PVCs on a BXM card. Also, if these parameters do not have values greater than 0, you will be unable to change the connection channel amount when you configure the BXM trunk using cnftrk. |
Start VSI VPI | By default the TSC (for example, the 7200 or 7500 series router) will use either a starting VSI VPI of 1 or 2 for tag switching, whichever is available. If both are available, a starting VSI VPI of 1 is used. The VPI range should be 2-15 on a BPX 8260 VSI. The VSI range for tag switching on the BPX 8620 is configured as a VSI partition, usually VSI partition number 1. VSI VPI 1 is reserved for AutoRoute PVCs, so the VSI partition for tag switching should start at VPI 2. If VPI 2 is not to be used, the tag switching VPI interface configuration command can be used on the TSC to override the defaults. The range is 2 to 4095. Always set to 2 for trunks. |
End VSI VPI | Two VPIs are sufficient for Release 9.1, although it may be advisable to reserve a larger range of VPIs for later expansion, for example, VPIs 2-15. The range is 2 to 4095. |
Minimum VSI Bandwidth | The minimum port bandwidth allocated to this partition in cells/sec. (Multiply by 400 based on 55 bytes per ATM cell to get approximate bits/sec.) The range is 0 to 352207. 0 is the default. |
Maximum VSI Bandwidth | The maximum port bandwidth allocated to this partition. This value is used for VSI QBIN bandwidth scaling. The range is 0 to 352207. 0 is the default. |

Last Command: dsplns
Next Command:
Use the dsptsmap command to display the channel to timeslot mapping usage information on a UVM card on an IGX node or a CDP/CVM card on an IPX node. The dsptsmap command is for use with the SVC caching feature which speeds up call setup for most VNS controlled calls. The SVC caching feature avoids some of the call setup/tear-down operations associated with addcon and delcon as a call originates or terminates. The SVC caching feature reduces the connect time for many switch calls over a busy network.
To use the dsptsmap command, the line must have SVC caching enabled on it. You can find out if a channel is disabled by using the dsptsmap command.
The cnfln command is used to configure the SVC caching parameter setting.
The dspcons command is used to view disabled connections provided the SVC has not been deleted.
The dsplncnf command will show the value (On/Off) of the SVC caching mode feature.
Refer to the VNS Installation and Configuration Manual for more information on SVC caching.
Display the channel to timeslot mapping usage for a UVM on an IGX node, or a CVM line on the IPX.

dsptsmap 7.2
Display channel to timeslot mapping for a specified line.
Parameter | Description |
---|---|
line_number | slot.line for UVM or line for CVM/CDP |
interval_number | Interval in seconds between screen updates. The default value is controlled by "Screen Update Time" in the cnfuiparm command. |
dsptsmap 9 1
Enabled channels are shown on the screen underlined and in reverse video. Disabled (cached) channels are shown with the channel number underlined and in reverse video, while the timeslot is shown in normal video. Channels that have no connection are shown in normal video for both channel number and timeslot.
For example:
The line_number parameter is specified in slot.line format for UVM and line format for CDP/CVM.
Use the optional update_interval parameter to control how often the screen gets updated. If no value is entered through the CLI, the value of the "Screen Update Time" parameter set using in the cnfuiparm command is used.

Activates (ups) a line. Use the upln command to make the line available for configuring and to start statistics gathering. You must activate ports at both ends of the line by executing the upport command before running upln. You must execute upln at both ends of the line. Executing upln at only one end of the line eventually causes an alarm. Once both ends of the line are active, you can add connections with the addcon command or optionally configure the line's signal characteristics for the data you intend for the line. See cnfln for information on defining the line characteristics.
A line consists of a cable for transmitting data and the interface circuitry for the line. The cable can be a coaxial wire, fiber optic, or a twisted pair. See Table 5-2 for information on card combinations.
