Information About Serial Interface Module
The serial interface module supports pseudowire transport over MPLS and raw socket for Async and Sync tranffic. The Serial IM interfaces monitor and detect cable connections, cable types and also monitors modem control signals periodically.
The A900-IMASER14A/S interface provides a direct connection between the Cisco ASR 920router and external networks.

We recommend that you use a smart serial or 4-port octopus cable to connect the A900-IMASER14A/S with the external network. |
