The NM-1CE1T1-PRI (1-port) and NM-2CE1T1-PRI (2-port) network modules provide support for T1, E1, and ISDN primary rate interface (PRI) network connections in a network module form factor. This feature (referred to in this document as NM-xCE1T1-PRI) offers attachment of one T1, E1, or ISDN PRI line on the 1-port module and two T1, E1, or ISDN PRI lines on the 2-port version.

This new feature (NM-xCE1T1-PRI) enables you to configure a single network module as either a T1 interface or an E1 interface on the same card. The configuration of a T1 or E1 interface and the change from one to the other is controlled by the card type command. Additionally, when in E1 mode, the module can be configured between channelized E1, ISDN PRI, E1-CAS-R2 (for modems, not for voice), balanced and unbalanced, and structured (G.704) versus unstructured (G.703) modes. In T1 mode, the module can be configured for channelized T1, T1-CAS, and as a CSU/DSU.

Note After you insert the NM-xCE1T1-PRI feature network module into the router chassis, you must use the card type command in the command-line interface (CLI) to configure the NM-xCE1T1-PRI feature. The controller will not be detected and cannot be configured until you use the card type command.

Configuration of the T1 or E1 interface can be customized using command-line interface (CLI) commands. In E1 mode, each port can be individually set to 120-ohm or 75-ohm termination. Each port has RJ-48C connectors, and there is one bantam jack that is shared by each port (for 2-port cards) for monitoring.
