TALKSWITCH INSTALLATION 9
1.5 USING 2 OR MORE TALKSWITCH UNITS ON A LAN
If you have one TalkSwitch unit, ignore this section and proceed to
Chapter 2: TalkSwitch Configuration.
1.5.1 Connecting 2 or more TalkSwitch units to a LAN
TalkSwitch 48-CA and -CVA units can be networked together on the same
LAN. Ensure you have the appropriate firmware on all units before adding
units to the LAN. Check www.talkswitch.com/support/ for the latest
updates.
We recommend integrating your phone system and your existing LAN with an
Ethernet switch. A switch provides direct communication between
TalkSwitch units, thus keeping the TalkSwitch voice-over-LAN data isolated
from other data on the network.
Connect up to four TalkSwitch units (2 are shown in the diagram above) to
the LAN switch or switched hub.
1.5.2 Setting the Unit ID for the first time
When TalkSwitch units are shipped from the manufacturer, they are
programmed with Unit ID 1. If two or more units are placed on the same LAN
with the same Unit ID number, it causes a conflict. TalkSwitch indicates this
by flashing all the line lights on the front panel of the units that have the
conflict.
Note: TalkSwitch unit enclosures are not designed for stacking. We
recommend wall-mounting units in a horizontal row to maximize airflow
and keep the units from overheating.
