LM-2E3 Module
The E3 Line Module for the ASI-1 Front Card is a backcard used to provide a physical interface to
the service interface (see Figure 5-6). The Line Module connects to the ASI-1 through the StrataBus
midplane. Two adjacent cards of the same type can be made redundant by using a Y-cable at the port
connectors.
Except for using two ports instead of three, the LM-2E3 back card operates similarly to the BNI back
cards, described previously.
