Terminals for internal and external calls. The MIC ON/OFF key or Feature

Two relays are provided on the ECR-U( ) ETU to use as an application
dictates. These relays are either off or on, and do not change state until a
station user manually makes the change.

GROUND START TRUNKS
Ground Start Trunks can be connected to the system. Assignment of trunks
as Ground Start is per trunk (by switch settings) at the associated
COI(8)-U( ) or COIB(4)-U10 ETU. Ground and Loop Start Trunks can be
mixed in the system per trunk. Ground Start Trunks are provided with line
supervision to reduce call collisions.

room can listen to a conversation over the built-in speaker of a Multiline
Terminal. While Group Listening is active, the Multiline Terminal user can
continue to talk on the handset or headset.

Handset Mute is provided to most terminals connected to the Electra Elite
IPK system. While talking on the Multiline Terminal handset, a station user
can dial a feature code or press the MIC button to mute the transmit speech
path. The station user can still hear the outside (or intercom) voice.

HANDSFREE ANSWERBACK
Each Multiline Terminal has a microphone for Handsfree Answerback during
internal voice calls. Microphone status is indicated by the MIC LED located
on each Multiline Terminal. The MIC key or Feature Access Code mutes the
microphone to ensure privacy.
