Features

External Device Alarming

Allows you to assign analog ports to alarm interfaces for external devices. You can specify a port location, information to identify the external device, and the alarm level to report when a contact closure occurs.

Facility Busy Indication

Allows users of multi-appearance telephones to see which lines, trunk groups, terminating extension groups, hunt groups, or paging zones (called resources or facilities) are busy. When the lamp associated with the resource is lit, the resource is busy.

You can store extension numbers, trunk group access codes, and Loudspeaker Paging access codes in a Facility Busy Indication button. The Facility Busy Indication button provides direct access to any of the facilities.

Facility Test Calls

Allows telephone users to make test calls to access specific trunks, dual tone multifrequency receivers, time slots, and system tones. The user dials an access code and makes the test call to make sure the facility is operating properly. Secu- rity measures are included to prevent unauthorized use.

Fiber Link Administration

Port cabinets are connected via direct fiber links or through fiber links to a center-stage switch to provide the connections required for voice and data infor- mation transfer. The center-stage switch is composed of switch node carriers that are interconnected by fiber links. It provides both circuit-switched and packet-switched connections. Fiber Link Administration creates the translation data defining these links by identifying the endpoint pairs for each link. Endpoints can be an expansion interface or a switch-node-interface circuit pack.

Go to Cover

Allows users who call another internal extension to send the call directly to cover- age.

Group Listen

Simultaneously activates your speakerphone in listen only mode and your hand- set or headset in listen and speak mode. This allows you to serve as spokesper- son for a group. You can participate in a conversation while everyone else in the room is listening to what is said.
