Survivable Remote Gateway
The Survivable Remote Gateway (SRG) extends CS 1000 features from a
main office to one or more remote SRG locations (branch offices). The
SRG50 Release 1.0 operates with the CS 1000 running Release 4.5 and is
backward compatible to Release 3.0 and Release 4.0. SRG does not operate
with CS 1000 Release 1.0 and Succession 1000 2.0 systems.
In addition to the SRG 1.0 model, which is positioned as the lower cost
alternative to the Media Gateway 1000B product, there is a new “mini” model
for the smaller branch office, known as the SRG50. The SRG50 is optimized
for the 5-32 user branch office.
