Configuring Line Attributes for an E&M Interface
This section describes how to configure line attributes for an E&M interface.
Pre-configuration Tasks
Before configuring an E&M interface, complete the following tasks:
- Registering a 6E&M interface card successfully.
- Ensuring that the 6E&M interface card works in correct line mode.
The 6E&M interface card supports the 4-wire mode and 2-wire mode, and works in 4-wire mode by default. If the line mode is incorrect, manually adjust the DIP switch to change the line mode. For the DIP switch adjustment method, see DIP Switch Usage Instructions in the NetEngine AR Hardware Description - Card.
Follow-up Procedure
After configuring line attributes for the E&M interface, you need to configure time division multiplexing (TDM) pseudo wire emulation edge-to-edge (PWE3) and an MPLS tunnel for data transmission between E&M devices. For details about the TDM PWE3 configuration, see PWE3 Configuration in the NetEngine AR Configuration Guide - VPN.
