Survivability
You can configure Standard Local Survivability (SLS) to enable a local media gateway to
provide a degree of MGC functionality when no link is available to an external MGC. SLS is
configured on a system-wide basis using the Provisioning and Installation Manager (PIM).
Alternatively, SLS can be configured from the individual media gateway itself using the CLI. SLS
supports all analog interfaces, ISDN BRI/PRI trunk interfaces, non-ISDN digital DS1 trunk
interfaces, IP phone, and IP Softphone.
