What to Do Next
Channelized E1 and T1 Primary Rate Interface (PRI) Integrated Services Digital Network (ISDN) port adapters (PA-2CE1/PRI-75, PA-2CE1/PRI-120, and PA-2CT1/PRI) are available on Cisco 7200 series routers, Cisco 7500 series routers, and on Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI).
The PA-2CE1/PRI-120 (balanced 120-ohm) and PA-2E1/PRI-75 (unbalanced 75-ohm) provide up to two channelized E1 interfaces to connect to channel service units (CSUs), and can transmit and receive data bidirectionally at the E1 rate of 2.048 Mbps. The PA-2CT1/PRI provides up to two channelized T1 interfaces to connect to CSUs, and can transmit and receive data bidirectionally at the T1 rate of 1.544 Mbps. The interfaces use a 15-pin, D-shell receptacle. The PA-2CE1/PRI-75 and PA-2E1/PRI-120 use G.703 serial interface cables, and the PA-2CT1/PRI uses standard serial cables (null-modem and straight-through).
This feature is supported on these platforms:
- Cisco 7200 series
- Cisco 7500 series
- Cisco 7000 series with the RSP7000 and RSP7000CI
For information on how to configure a basic channelized E1 controller on the PA-2CE1/PRI-75 and PA-2CE1/PRI-120 port adapters, refer to 'Configure Channelized E1' section in the 'Configuring Interfaces' chapter in the Configuration Fundamentals Configuration Guide. For information on how to configure a basic channelized E1 ISDN PRI, refer to the 'Configure Channelized E1 ISDN PRI' section in the 'Configuring ISDN' chapter in the Wide-Area Networking Configuration Guide.
For information on how to configure a basic channelized T1 controller on the PA-2CT1/PRI port adapter, refer to the 'Configure Channelized T1' section in the 'Configuring Interfaces' chapter in the Configuration Fundamentals Configuration Guide. For information on how to configure a basic channelized T1 ISDN PRI, refer to the 'Configure Channelized T1 ISDN PRI' section in the 'Configuring ISDN' chapter in the Wide-Area Networking Configuration Guide.
Note When a channelized E1 or T1 port adapter is used for ISDN PRI, it can support dial-on-demand routing (DDR). For more information on DDR, refer to the 'Configuring DDR' chapter in the Wide-Area Networking Configuration Guide.A channelized E1 controller can have up to 31 serial interfaces (numbered 0 to 30), and a channelized T1 controller can have up to 24 serial interfaces (numbered 0 to 23). After you define the channel groups or PRI groups, you can configure each group as a serial interface. For information on how to configure a serial interface, refer to the 'Configure a Synchronous Serial Interface' section in the 'Configuring Interfaces' chapter of the Configuration Fundamentals Configuration Guide.
For information on other commands that can be used by the PA-2CE1/PRI-75 and PA-2CE1/PRI-120 interfaces, refer to the Cisco IOS Release 11.2 configuration guides.
The following example shows how to configure a basic channelized E1 PRI ISDN port adapter. In this example, the controller is enabled, timeslots are assigned to the PRI group, and the ISDN switch type used on all ISDN interfaces on the router is a switch for the European community (primary-net5). The PRI group timeslots of 1, 3, 4, 5, and 7 (the B channels) are selected to map to timeslot 16 (the D channel), which is recognized by the system as timeslot 15.
The following example shows how to configure a basic channelized T1 PRI ISDN port adapter. In this example, the controller is enabled, timeslots are assigned to the PRI group, and the ISDN switch type used on all ISDN interfaces on the router is for the United States switch (primary-5ess). The PRI group timeslots of 1, 3, 4, 5, and 7 (the B channels) are selected to map to timeslot 24 (the D channel), which is recognized by the system as timeslot 23.
Note You might also need to enter other configuration commands depending on the requirements for your system configuration and the protocols you plan to route on the interface. For more information, refer to the Cisco IOS Release 11.2 configuration guides.Note For additional examples, refer to the 'Interface Configuration Examples' section of the 'Configuring Interfaces' chapter of the Configuration Fundamentals Configuration Guide.This section documents modified commands. All other commands used with this feature are documented in the Cisco IOS Release 11.2 command references.
