Survivability
The G250 Media Gateway supports Standard Local Survivability (SLS). SLS is a configurable
software module that allows a local G250 to provide a core set of Media Gateway Controller
functions when no link is available to the server, an LSP, or an Enterprise Survivable Server
(ESS). SLS is configured on a system-wide basis using the new Provisioning and Installation
Manager (PIM), or SLS can be configured on an individual G250 using the command line
interface (CLI).
SLS is supported as follows on the G350:
● G250-Analog: SLS supported for all analog interfaces, IP phone, and IP Softphone
● G250-BRI: SLS supported for all analog interfaces, ISDN BRI trunk interfaces, IP phone,
and IP Softphone
● G250-DCP: SLS supported for all analog and DCP interfaces, IP phone, IP Softphone, and
DCP phone
● G250-DS1: SLS supported for all analog interfaces, ISDN PRI trunk interfaces, non-ISDN
digital DS1 trunk interfaces, IP phone, and IP Softphone
