Chapter 14: Configuring contact closure
You can use contact closure to control up to two electrical devices remotely. With contact
closure, you can dial feature access codes on a telephone to activate, deactivate, or pulse
electrical devices such as electrical door locks. You can also activate and deactivate contact
closure using CLI commands. You can only use feature access codes if you configure the
Avaya G250/G350 Media Gateway to use a server with Avaya Communication Manager
software. For more information, see
Configuring the Media Gateway Controller (MGC) on
page 92.
It is recommended that you use an Avaya Partner Contact Closure Adjunct™ for contact
closure. For more information, see
Overview for the Avaya G250 and Avaya G350 Media
Gateways , 03-300435. An Avaya Partner Contact Closure Adjunct™ contains two relays, one
for each electrical device. You can control each relay in any of the following ways:
●
When you dial the contact closure open access code, the relay opens (no contact)
●
When you dial the contact closure close access code, the relay closes (contact)
●
When you dial the contact closure pulse access code, the relay closes (contact) for the
pulse duration and then opens (no contact)
●
You can control each contact closure relay manually with CLI commands or with Avaya
G350 Manager
Note:
Note:
Configuration of the feature access code is performed through the Avaya
Communication Manager. For more information, see
Administrator Guide for
Avaya Communication Manager , 03-300509.

on both the G250 and the G350 front panels. Use a telephone cable with standard RJ-11
connectors.

Partner Contact Closure Adjunct™. For information on contact closure specifications, see
