SBA for Microsoft Lync 29 December 2010
2.1.2.5 Connecting to E1/T1 Trunks
The procedure below describes the cabling of the device's TRUNKS module interfaces (i.e.,
E1/T1 trunks).
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 digital trunk interfaces:
1. Connect the E1/T1 trunk cables to the ports on the device's TRUNKS module(s).
2. Connect the other ends of the trunk cables to your PBX/PSTN switch.
RJ-48c trunk connectors are wired according to the figure below:

2.1.2.6 Connecting to Power
The device can house up to two extractable power supply modules (Power 1 and Power 2), each
providing an AC power connector on the device's rear panel. The dual power option provides the
device with power redundancy.
Warnings:
Units must be connected (by service personnel) to a socket-outlet with a protective
earthing connection.
Use only the AC power cord supplied with the device.
¾ To connect the device to the power supply:
On the device's rear panel, connect the left (active) 100-240V~50-60 Hz power socket to a
standard electrical outlet using the supplied AC power cord.
The front panel of the power supply module provides a LED (labeled POWER) that is lit green
when the device is powered up. If this LED is off, a power supply problem may be present.
Notes:
If both power units are used (for load sharing - failure protection / redundancy),
ensure that you connect each power supply unit to a different AC supply circuit.
The two AC power sources must have the same ground potential.
