Standard Local Survivability (SLS)

Standard Local Survivability (SLS) provides a local Branch Gateway with a limited subset of
MGC functionality when there is no IP-routed WAN link available to an MGC, or no MGC is
available.
SLS is supported on IPv4 only.
SLS is not a replacement for ELS or SRS (Survivable Remote Server) survivability, which offer
full call-feature functionality and full translations in the survivable mode. Instead, SLS is a cost-
effective survivability alternative offering limited call processing in survivable mode. Although
the Branch Gateway can host an S8300 Server in ICC or SRS mode, SLS offers both local
survivability and call control.
In contrast to the server-based survivability features, SLS operates entirely from the Branch
Gateway and requires a data set comprised of Avaya Aura
translations (survivable ARS analysis and configuration data). This data set is compiled and
distributed to a group of devices using the Provisioning and Installation Manager (PIM). In the
absence of the PIM, the data set can be configured manually from individual Branch Gateways
using CLI commands. For instructions on configuring SLS, see
page 120.
