2.4.7 Connecting to E1/T1 Trunks
The procedure below describes the cabling of the device's E1/T1 trunk.
Warning: To protect against electrical shock and fire, use a 26 AWG min wire to
connect T1 or E1 ports to the PSTN.
¾ To connect the E1/T1 trunk interface:
1. Connect the E1/T1 trunk cable to the device’s E1/T1 port.
2. Connect the other end of the trunk cable to your PBX/PSTN switch.
RJ-48c trunk connectors are wired according to the figure below:

2.4.8 Connecting the OSN Server
The device may (see Note below) be ordered with an embedded, Open Network Solution
(OSN) platform for hosting third-party services (such as an IP PBX). The OSN server
features an Intel® Atom™ 1.6 GHz processor, with 1GB or 2GB RAM (depending on
Mediant 800 model), and a single storage hard disk drive (SATA storage).
The OSN server's port interfaces are located on the device's rear panel. These ports
include three USB ports for connecting computer peripherals such as a mouse and
keyboard, one VGA port for connecting to a monitor, and two Gigabit Ethernet ports for
connecting to Ethernet interfaces such as LAN and/or WAN.
Notes:
• The OSN server platform is a customer ordered feature. The OSN
interface ports on its rear panel are available only when the OSN is
ordered.
• The OSN server also provides an internal interface connection to the
Mediant 800 LAN switch. In other words, instead of using the two Gigabit
Ethernet ports on the rear panel, you can use one of the LAN ports
located on the front panel for connecting to the OSN server.
• If your device is shipped with an OSN server, you can obtain the latest
OSN drivers from http://www.audiocodes.com/downloads.
