Cisco 7304 6-Port Clear Channel E3 Line Card Installation and Configuration

OL-5061-01

Chapter 4 Configuring the 6E3 Line Card

Configuring the Interfaces

Table 4-4 shows the default values for the 6E3 line card serial interfaces.

Customizing the 6E3 Line Card Configuration

There are two sides to the network, a local network side and a remote customer side, or near and far ends.

The 6E3 line card supports third-party data service units (DSUs), Internet Service Provider

(ISP)-provided E3 lines, and so on. The configuration parameter default values in the 6E3 line card port

interfaces must match the remote DSUs on your network. Table 4-5 shows the configuration parameters.

Note The local port and the remote port must have matching configurations.
