Avaya S8700 Media Server configurations
The following hardware products are components of Communication Manager:
■ Avaya S8700 Media Server for IP Connect Configurations comprises an
Avaya S8700 Media Server with an Avaya™ G600 Media Gateway.
■ Avaya S8700 Media Server for Multi-Connect Configurations comprises
an Avaya S8700 Media Server with an MCC1 or SCC1 Media Gateway.
The single-carrier cabinets and multi-carrier cabinets are existing Avaya
products enhanced for use in these configurations for the media servers.
■ Avaya S8700 Media Server also may be configured to control a remote
Avaya G700 Media Gateway. This configuration also typically features an
Avaya S8300 Media Server in the G700 Media Gateway, with the S8300
serving as Local Survivable Processor (LSP), rather than primary call
controller.
S8700 Media Server with G600 Media Gateway
The S8700 Media Server with G600 Media Gateway (called “IP Connect”)
configurations is an all-IP, 19 inch data rack component. The S8700 IP Connect is
always comprised of two duplicated S8700 Media Servers running the Linux
operating system, at least one Ethernet switch within the customer’s own local
area network (LAN) or one provided by Avaya for the customer’s LAN, and up to
64 Port Networks (PN) using G600 Media Gateways.
Each server is backed-up by a duplicated uninterruptible power supply (UPS). It is
strongly recommended that the Ethernet switch is also backed up by a UPS. This
duplex reliability scheme is the only supported configuration. Also note that
mixing of G600 Media Gateways with traditional expansion port network
cabinets, CMC1, SCC1 and MCC1, is not supported.
The S8700 IP Connect provides the advantage of IP connectivity between PNs.
Utilizing customer’s existing IP infrastructure, the S8700 Media Server for IP
Connect configuration saves customers the cost of building a separate telephony
network. As an all-IP configuration, traditional forms of bearer network direct
connect, Center Stage Switch (CSS) connect, and ATM PN connectivity are not
supported. Also, traditional survivability options are not supported such as the
Survivable Remote Processor or the ATM WAN Spare Processor.
S8700 IP Connect supports as many as 12,000 IP endpoints and 4,000 traditional
endpoints such as DCP, Analog and ISDN. However, DMI Mode 2, Data
Modules, and Mode 3 data or BX.25 links are not supported.
The two S8700 Media Servers, commercial servers with Intel Pentium III
processors, can be located anywhere in the network and can be physically
separated by up to 100 meters of cable distance.
