Avaya S8700-series Media Servers
Note:
modem relay is needed primarily for secure SCIP telephones (formerly
known as Future Narrowband Digital Terminal (FNBDT) 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
Note:
Note: The path between endpoints for modem tone transmissions must use Avaya
telecommunications and networking equipment.
See TN2302AP IP media processor on page 256 or TN2602AP IP Media Resource 320 on
page 267 for more information. See also Administration for Network Connectivity for Avaya
Communication Manager, 555-233-504, for more information.
The software duplication feature of the S8720 eliminates the need for the DAL1 or DAL2
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:
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 or DAL2 board is available as an option for connections to the duplicated server. If
purchased, the DAL1 or DAL2 memory duplication cards and the dual fiber cable linking the
DAL1 or DAL2 cards are installed in the S8720 media servers separately.
Note:
Note: DAL2 cards are required for the extra large configuration of the S8720 media
server.
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
