S8300 primary controller architecture
The S8300 Media Server has the same form factor as the Avaya media modules. The S8300 is
installed in slot V1 of the G700 or G350 Media Gateway. The S8300 can be configured as either
a primary controller (a.k.a. “ICC”) or as a local survivable processor (LSP).
Configured as a primary controller, the S8300 provides Communication Manager call control.
The controller targets the small-line-size, cost-conscious portion of the market, and as such,
must be cost competitive with other solutions. The controller is based on standard Intel IA32
architecture, and runs the industry-standard Linux operating system.
The S8300 runs the following co-resident applications:
●
H.248 Media Gateway Controller
●
H.323 GateKeeper
●
Communication Manager Feature Server
●
INTUITY AUDIX Messaging system (installed in the G700)
The S8300 primary controller, when installed in the G700, can be ordered both with and without
INTUITY AUDIX support.
The S8300 faceplate provides connectivity for two USB devices, and an Ethernet port for
technician access. The faceplate also has operational LEDs and a shutdown switch. The media
module backplane connector provides the interfaces for the internal 10/100 Ethernet bus and
the TDM Bus.
An S8300 primary controller can control up to 50 G700 or G350 Media Gateways, 450 stations,
and 450 trunks.
S8300 as the Local Survivable Processor (LSP)
The LSP is an S8300 Media Server installed in a G700 or G350 Media Gateway. The LSP
provides survivability when the primary controller, either an S8300 ICC or an S8700 External
Communications Controller (ECC), is inaccessible. Each system can have multiple LSPs. Each
LSP has a copy of the primary controller’s translations. The translations are updated regularly
from the primary controller b way of a virtual link through an IP network. Typically, all LSPs are
in idle mode, where the LSPs are not processing any calls. When the Media Gateway's
Processor (MGP) or individual IP endpoints perceive the primary controller to be unreachable,
the MGP or the IP endpoints attempt to register with an LSP. The LSP does not actively take
over when the primary controller becomes unreachable, but waits for MGPs and IP endpoints to
register with it. Each LSP runs in license-normal mode until IP Telephones or MGPs register
with it, which triggers the LSP to move into a license-error mode. Each LSP can run in active
mode for a maximum of 10 days per outage before it must be reset manually. A “reset 3”
command on the LSP forces devices registered with it to return to their primary controller. When
the customer resets the LSP, the 10-day license timer is reset after it contacts the primary
controller.
