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 this illustration) to the LAN switch or switched hub.

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.

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.

To resolve the conflict, assign a different Unit ID each of the units. Pick up a telephone handset connected to one of the extension ports on the TalkSwitch unit you want to assign a different Unit ID to. You immediately hear a system prompt indicating that there is a conflict and a new Unit ID needs to be chosen. Select an available Unit ID between 2 and 4.

The system indicates that the update was successful and the front panel lights stop flashing after several seconds. When none of the front panel ‘Line’ lights are flashing, all the units are ready for network use.

Note: No IP information is required to configure TalkSwitch since it does not use the TCP/IP protocol for voice traffic over the LAN.

IP configuration is required for remote management or VoIP once the system has been configured.
