The TN799DP Control-LAN (C-LAN) circuit pack provides firmware download functionality while
the TN2501 Voice Announcement over LAN (VAL) circuit pack provides announcement
functionality.
The S8400 Server provides a Voice over Internet Protocol (VoIP) based integrated messaging
capability for up to 450 light duty users. This option requires that 8 ports of VoIP resources be
provisioned with the S8400 Server. The hard disk drive stores the messages and a TN2302AP
IP Media Processor circuit pack usually provides the VoIP resources.
An external messaging system is required when an S8400 Server based system is configured
for more than 450 light duty users that requires messaging.
The S8400 Server supports a single port network (PN), which can be composed of:
● up to 5 G650s
● up to 4 CMC1s
● up to 3 G600s
The S8400 also supports up to 5 H.248 media gateways, including:
● G700
● G450
● G350
● G250
The S8400 can support up to 80 G150 Media Gateways.
The S8400 Server cannot be configured as an Enterprise Survivable Server (ESS) or Local
Survivable Processor (LSP). But a G700, G450, G350, or G250 Media Gateway connected to
an S8400 Server can have an LSP installed. In the event that the media gateway can no longer
communicate with the S8400, the LSP takes over all call processing functions for that gateway.
However, the LSP does not take on any of the call processing functions for those trunks and
endpoints that are directly connected to the S8400.
The S8400 Server consists of three separate TN circuit packs; two required and one optional:
● TN8400AP circuit pack that provides
- Avaya Communication Manager call processing
- coresident voicemail
- on board diagnostics
- autonomous alarming
● TN8412AP S8400 IP Interface (SIPI) that provides
- low-level control functions and services for a TN port network
- tone detection and generation
- carrier maintenance and diagnostics
- input/output of alarm leads
