ISDN 8503T Voice Terminal

Used with the CONF/RING button to select one of eight possible personalized ringing patterns

Used with the DROP/TEST button to initiate a self-test of the voice terminal lights and ringer.

Note: If the user picks up on an incoming call while the voice terminal is in program mode, the voice terminal will automatically exit program mode.

MEMORY button

When the user presses the MEMORY button and one of the 12 dial pad keys (memory-dialing locations), while off-hook, the voice terminal automatically dials the number or access code stored on that dial pad key.

The user can clear a memory-dialing location by entering program mode, and then pressing the MEMORY button and the appropriate dial pad key on which the number or code is stored.

REDIAL button

With the Redial feature, the user can redial the telephone number last dialed from the dial pad. (The handset must be off-hook.) Up to 37 digits can be redialed.

MUTE button

While on a call, the user can press the MUTE button (the red light next to the button goes on), so the user can converse with someone in the same room without the other party hearing the conversation. The user is placed in listen-only mode. To disable the feature, the user presses the MUTE button a second time (the red light goes off).

Volume control button

When the user is on a call, the Volume ‘‘arrow’’ button raises or lowers the volume on the handset. When the handset is on-hook, this button raises or lowers the ringer volume.

Self-Test

The 8503T voice terminal is equipped with a Self-Test feature. When the user presses the PRO- GRAM button and then the DROP/TEST button, while on-hook, the user can test the button lights and the ringer.
