1 PA-MC-T3 Multi-Channel T3 Synchronous Serial Port Adapter Enhancement This feature module describes the PA-MC-T3 Multi-Channel T3 port adapter (PA-MC-T3 [=]), which can now be configured as either customer equipment or network equipment. This document includes the following sections: Feature Overview, page 1 Supported Platforms, page 2 Supported Standards, MIBs, and RFCs, page 2 Configuration Tasks, page 2 Configuration Examples, page 3 Command Reference, page 6 Feature Overview The addition of the equipment {customer network} loopback command enables you to configure the PA-T3-MC as network equipment or customer equipment so it can operate based on the ANSI T1.403 standard. When a PA-MC-T3 is configured as Customer Equipment, all loopback requests are honored. When configured as network equipment the PA-MC-T3 ignores the following DS-3 and DS-1 loopback requests: Far-end alarm control (FEAC) code requests for the DS-3 line 1-28 DS-1 line loop-up or loop-down Payload loop-up or loop-down Line loopback full rate patterns of 0001 and 001 loop-up or loop-down Extended Superframe data link (ESF-DL) line loop-up or loop-down ESF-DL payload loop-up or loop-down ESF-DL SX.25 payload loop-up or loop-down When configured as network equipment, the PA-MC-T3 recognizes router network loop commands as line loopback commands. Simple Network Management Protocol (SNMP) requests for loopbacks are always honored, whether the PA-MC-T3 is configured as customer equipment or network equipment. 1

With the addition of the ability to configure the PA-MC-T3 as network equipment or customer equipment, the PA-MC-T3 no longer responds to in-band control-line loopback codes when configured as customer equipment. The PA-MC-T3 can now disable network (line and payload) loopbacks on both the T3 and T1 connections. This prevents customers from setting loopbacks at the network end. This feature is useful for all router equipment deployed as network equipment that interfaces with customer equipment.

3 PA-MC-T3 Multi-Channel T3 Synchronous Serial Port Adapter Enhancement Configuration Examples Configuring the T3 Controller A T3 Controller must be selected before other configuration commands can be enabled. Command Router(config)# controller t3 slot/port-adapter/port Purpose Selects a T3 controller. Configuring the T1 Lines Perform the following steps to configure each logical channel group: Step Commands Purpose Step 1 Router(config)# controller t3 slot/port-adapter-port Selects a T3 controller. Step 2 Router(config-controller)# t1 line channel-group number timeslots range Configures the T1 line with a value of 1 to 3 in a logical channel group (values are 0 to 23) and specifies the timeslots (values are 1 to 24). Verifying the Configuration To verify the interface, T1 line and T3 controller configurations, perform the following steps: Step 1 Enter the show interfaces serial command in privileged EXEC mode to display information about the newly configured interfaces. show interfaces serial [slot/port-adapter/port/t1-line] [:channel-group] (for Cisco 7500 series routers) show interfaces serial [slot/port/t1-line] [:channel-group] (for Cisco 7200 series routers) Step 2 Enter the show controllers t3 command to in privileged EXEC mode to display information for all 28 T1 lines within each T3 port adapter in the router.

6 Command Reference PA-MC-T3 Multi-Channel T3 Synchronous Serial Port Adapter Enhancement Command Reference This section documents the new command that configures the Equipment feature. All other commands used with PA-MC-T3 are documented in the Cisco IOS Release 12.0 command reference publications. In Cisco IOS Release 12.0(1)T or later, you can search and filter the output for show and more commands. This functionality is useful when you need to sort through large amounts of output, or if you want to exclude output that you do not need to see. To use this functionality, enter a show or more command followed by the pipe character ( ), one of the keywords begin, include, or exclude, and an expression that you want to search or filter on: command {begin include exclude} regular-expression Following is an example of the show atm vc command in which you want the command output to begin with the first line where the expression PeakRate appears: show atm vc begin PeakRate For more information on the search and filter functionality, refer to the Cisco IOS Release 12.0(1)T feature module titled CLI String Search. 6

To return to the default setting, use the no form of this command. equipment {customer network} loopback no equipment {customer network} loopback Syntax Description customer network Configures the PA-MC-T3 as customer equipment. Configures the PA-MC-T3 as network equipment. Defaults Customer equipment Command Modes Configuration controller Command History Release 12.0(7)XE1 Modification This command was introduced. Usage Guidelines Use this command to configure the PA-MC-T3 as network equipment or customer equipment so it operates according to the T1.403 ANSI standard, allowing equipment configured as network equipment to disregard network loopback commands.
