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 media server with Avaya Communication Manager
software. For more information, see
page 71.
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:
Configuration of the feature access code is performed through the Avaya
Note:
Communication Manager. For more information, see Administrator Guide for
Avaya Communication Manager, 03-300509.

Contact closure hardware configuration

1. Connect an Avaya Partner Contact Closure Adjunct to the Contact Closure port on the
Avaya G250/G350 Media Gateway front panel. The Contact Closure port is labeled CCA
on both the G250 and the G350 front panels. Use a telephone cable with standard RJ-11
connectors.
2. A qualified electrician should connect the electrical devices to the relays on the Avaya
Partner Contact Closure Adjunct. For information on contact closure specifications, see
Overview for the Avaya G250 and Avaya G350 Media Gateways, 03-300435.
