ISDN Voice Terminals

The dial pad keys can also be used as memory-dialing locations. By pressing the
PROGRAM button to enter program mode, the user can store a programmed
number or access code on each of the 12 dial pad keys (memory-dialing
locations). With the MEMORY button, the user can dial these programmed
numbers.
Ringing
The 8503T voice terminal has electronic tone ringing with eight possible
personalized ringing patterns that can be selected by pressing the PROGRAM
button and then the CONF/RING button, while on-hook. Ringer volume is
controlled by the Volume “arrow” button when the voice terminal is on-hook.
Jacks
The 8503T voice terminal housing contains three jacks. The Handset cord jack,
for connecting the handset to the voice terminal, is located on the bottom of the
housing, near the front of the voice terminal. The Line jack, for connecting the line
cord to the voice terminal, is located on the bottom (left center) of the voice
terminal. The Adjunct jack, which is located on the bottom of the voice terminal
directly below the Line jack, is used for connecting optional adjunct equipment
such as an S201A Speakerphone or a 500A Headset Adapter to the voice
terminal.
Cords
Two cords are supplied with the 8503T voice terminal: a coiled 9-foot modular
Handset cord and a 7-foot Line cord. An optional 12-foot Handset cord is
available.
ROM cartridge
A ROM cartridge is installed in each voice terminal, but is easily removed and
replaced so that the firmware can always be updated. The cartridge can be
removed from the bottom of the housing by pressing the tab on the cartridge and
then lifting it from the housing. The cartridge can be inserted into the housing by
pressing the tab on the cartridge and then pressing it down into the bottom of the
housing.
Mounting Options
The 8503T voice terminal comes equipped with a desk stand. However, the desk
stand can be removed, and the voice terminal can be mounted on the wall.
Color Options
The 8503T voice terminal is available in black or in white.
