MAINTENANCE SUPPORT
for S8720, S8710, & S8700 Servers with Avaya Communication Manager Software and G700, G650, G350, G250, CMC, SCC, or MCC Media Gateways

Overview

The Avaya S8720, S8710 & S8700 media servers use a standard microprocessor engine on a commercial server. The S8710 and S8720 media servers are very similar in architecture, components, and functionality. Both servers support Communication Manager. The main differences between the two are:

  • The S8720 has greater call processing performance than the S8710
  • The S8710 uses a Pentium 4 processor, whereas the S8720 uses an AMD Opteron processor.
  • Software duplication is available on the S8720. The S8720 is ordered without the DAL1 card used for hardware duplication. Hardware duplication, and the DAL1 card, can be purchased as an option for the S8720.
  • The S8720 has a third USB port, which is located on the front panel.

The S8700-series media servers use high-speed connections to route voice, data, and video between the following trunks and lines:

  • Analog and digital trunks
  • Data lines that are connected to host computers, data-entry terminals, personal computers, and internet addresses

The S8700-series media servers use a Linux platform on a commercial server. The S8700-series media servers are derived from the Avaya processor. But the S8700-series media servers have fewer physical components, and provides most of the same features and functionality with increased capacity.

Configuration information
Both the S8710 and S8720 Media Servers support two types of port network configurations, or a combination of both:

  • Voice bearer over IP (IP-Connect): An all-IP configuration that carries both control and bearer information.
  • Voice bearer over fiber connections (Multi-Connect) with direct-connect expansion interface circuit packs, Center Stage Switch (CSS), or Asynchronous Transfer Mode (ATM).

In fiber-connected configurations, the bearer paths and control paths are separate. The control information for port networks travels over a control network. The control information terminates on the S8710 or S8720 Media Server at one end and an IP Server Interface (IPSI) circuit pack on the other. The control network can be of one of the following networks:

  • A dedicated control network in which an Ethernet switch is used only for the control network and therefore creates a private LAN
  • A nondedicated control network in which control data passes through an Ethernet switch that is also connected to the customer LAN

S8720 Media Server
The S8720 server’s dimensions are (HxWxD) 3.38 in. (8.6 cm.) x 17.50 in. (44.5 cm.) x 25.75 in. (65.4 cm.). The S8720 Media Server has a 2U form factor.

Characteristics of the S8720 Media Server include:

  • AMD Opteron processor
  • 1 GB memory
  • 72GB 10,000 RPM SCSI hard disk drive
  • 2 10 / 100 / 1000 Ethernet ports on the motherboard to support IPSI network control links, services access, and administration
  • Three USB ports, for modem connection, Compact Flash drive connection, and other connections
  • External (USB) Compact Flash
  • 4-port (10 / 100BaseT) network interface card (quad NIC)
  • A SCSI CD / DVD-ROM
  • Supports software duplication. Hardware duplication is available with the optional DAL1 Duplication board.
  • A distance limitation of 10 km between the S8720 Media Servers in the pair
  • Support for global power ranges from 100V to 250V AC
  • Active / standby status LED for easy in rack server identification
  • Supports secure HTTP server for IP phone file downloads.
  • Transport, using Communication Manager and an appropriate media processor (T2302AP or TN2602AP), of the following messages:
    • Fax, Teletypewriter device (TTY), and modem calls using pass-through mode
    • Fax, V.32 modem, and TTY calls using proprietary relay mode

Note:
V.32 modem relay is needed primarily for secure SCIP telephones and STE BRI telephones.

    • T.38 Fax over the Internet, including endpoints connected to non-Avaya systems
    • 64kbps clear channel transport in support of firmware downloads, BRI secure telephones, and data appliances

The software duplication feature of the S8720 eliminates the need for the DAL1 memory duplication card. If software duplication is used, the functions of the Eth0 and Eth2 interfaces are reversed with respect to the hardware duplication functions. Memory duplication messages are sent over the server duplication TCP / IP link.

Note:
Using software duplication may reduce system performance. Avaya recommends a dedicated duplication link for software duplication. If the duplication is routed or switched, the link should have a bandwidth of 1 Gigabit per second.

A DAL1 board is available as an option for connections to the duplicated server. If purchased, the DAL1 hardware duplication cards and the dual fiber cable linking the DAL1 cards are installed in the S8720 media servers separately.

The S8720 Media Server is usually mounted in a 4-post rack with square holes. It can, however, also be mounted in a 2-post rack if you use an adapter kit. In either case, the server must slide out using rails or a slide-out shelf.

The power supply of the S8720 Media Server has the following input requirements:

  • Line Voltage Range: 90 to 132 VAC / 180 to 265 VAC
  • Nominal Line Voltage: 100 to 120 VAC / 220 to 240 VAC
  • Rated Input Current: 6A (110V) to 3A (220V)
  • Rated Input Frequency: 50 to 60 Hz
  • Rated Input Power: 600W

See the following figures for an example of the S8720 Media Server. Figure 17 shows a front view.

S8710 Media Server
The S8710 server’s dimensions are (HxWxD) 3.38 in. (8.6 cm.) x 17.50 in. (44.5 cm.) x 25.75 in. (65.4 cm.). The S8710 Media Server has a 2U form factor.

Characteristics of the S8710 Media Server include:

  • 3.06 GHz P4 processor
  • 512 MB memory
  • 72GB 10,000 RPM SCSI hard disk drive
  • 2 10 / 100 / 1000 Ethernet ports on the motherboard to support IPSI network control links, services access, and administration
  • Two USB ports, one of which you use for a modem connection and the other to connect the Compact Flash drive
  • External (USB) Compact Flash
  • 4-port (10 / 100BaseT) network interface card (quad NIC)
  • A SCSI CD / DVD-ROM
  • A DAL1 Duplication board for connections to the duplicated server.

A DAL1 board resides in a PCI slot on both the active server and the standby server. The DAL1 operates in either active or standby mode to match the mode of its server. The active server saves data to its DAL1 board. Then, the data is also sent over the fiber link to the DAL1 board on the standby server.

  • A distance limitation of 10 km between the S8710 Media Servers in the pair
  • Support for global power ranges from 100V to 250V AC
  • Active / standby status LED for easy in rack server identification

See the following figures for an example of the S8710 Media Server.

S8700 media server control complex
Both configurations, voice bearer over IP and voice bearer over direct-connect, CSS or ATM, use the following components and software:

  • Two media servers. S8710 Media Server or S8720 Media Server.

Note:
Both media servers must be of the same type, either S8710 or S8720 Media Servers. You cannot have a server pair with an S8710 and an S8720 Media Server.

● Media gateways for main locations, which individually or as stacks serve as port networks and include one or more of the following types:

    • Avaya G650 Media Gateway (default for new systems), which is always sold with new systems
    • G600 Media Gateway, with a migration system only
    • CMC1 Media Gateway, with a migration system only
    • SCC1 Media Gateway, with a migration system only
    • MCC1 Media Gateway, with a migration system only

Note:
The Avaya G700 Media Gateway, the Avaya G350 Media Gateway, the Avaya G250 Media Gateway, and the G150 Media Gateway are supported through the C-LAN circuit pack. The C-LAN circuit pack can be mounted in any of the gateways previously listed.

Note:
Media Gateway types cannot be mixed within the same port network (PN).

  • TN2312BP IP server interface, which provides control signaling from the media server to the port networks (PNs). At least one PN in a fiber-connected configuration must contain a TN2312BP circuit pack. In an IP-connect configuration, each PN must contain one or two TN2312BP circuit packs.
  • TN2302AP IP media processor or TN2602AP IP Media Resource 320, which provides TDM-to-IP conversions of audio signals. At least one of these circuit packs is required in each PN that uses the IP-connect connection method to the media server.
