Dialing Out
1. The SROS determines to place an outbound call when either the Layer 1 or Layer 2 has a failure.
2. When placing outbound calls, the SROS matches the number dialed to a PPP interface.
3. When placing the call, the SROS uses the configuration of the related PPP interface for authentication and IP
negotiation.
4. If the call fails to connect on the first number dialed, the SROS places a call to the second number if
configured. The second number to be dialed references a separate PPP interface.
Dialing In
1. The SROS receives an inbound call on a physical interface.
2. Caller ID is used to match the
backup number
command to the configured PPP interface.
3. If a match is found, the call connects and the SROS pulls down the primary connection if it is not already in a
down state.
4.If no match is found from Caller ID, the call is terminated.
