Cisco NM-2CE1T1-PRI= Network Module - 2-port channelized E1/T1/ISDN-PRI - Brushes

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. \n\nThis 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, 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.
