Options key
(continued) • Key Click Enable – provide audible feedback when using the dial pad (no
feedback is given when the option is off)
• Headset Port On Call – enable or disable the call in progress indication feature.
This feature requires a lamp-type accessory to be connected to the headset port
of the terminal, which is signaled by the terminal while a call is in progress. The
terminal turns on the accessory lamp while calls are in progress, and turns the
lamp off once the call is terminated.
• Headset Port External Alerter – enable or disable the external alerter feature.
This feature depends on connecting an external alerter to the headset port of
the terminal. If enabled, the terminal signals the external alerter when the
system has turned alerting on. Both the on call and external alerter features can
be enabled simultaneously.
Note: This feature is reserved for future third-party equipment.

Message key This is a fixed feature key that corresponds to feature/option key 17. You must
program this key using SERVORD commands. Although it is permanently labeled
as message, it does not have to be datafilled as such. In order to access voice mail
without a message waiting, Nortel Networks recommends assigning Message to
Key 1 and Autodial to the message key (Key 17.) The Autodial key should be
programmed with the voice mail system DN.
