to the terminal, is located on the bottom (left center) of the 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 terminal.
NOTE:
When an ADB (board) is installed in the 8510T terminal for data operations,
the RS232 jack is visible on the rear of the set for connecting data
equipment. When a TMI board is installed in the 8510T, two jacks are visible
on the rear of the set: the RS232 for the data connection and an 8-pin round
connector for connection of a video cable.
Cords
Two cords are supplied with the 8510T: a coiled 9-foot modular Handset cord and
a 7-foot Line cord. An optional 12-foot Handset cord is available.
ADB and TMI Boards
An Asynchronous Data Board (ADB) can be installed in the 8510T for data
applications. A TMI (Telephone Multimedia Interface) board can be installed if the
8510T is to be used as a video terminal.
Mounting Options

Power Requirements
Phantom or Auxiliary Power
The 8510T can receive power from the switch or from an auxiliar y power supply.
NOTE:
A voice/data set should be auxiliary powered only.
The installer can select the type of power used by placing the two power jumpers
over the correct set of pins.
The power option jumpers are located at the bottom center of the terminal. On the
right side of the pins, on the plastic housing, you will see the labelPOWERand a
diagram of the correct settings. The jumpers are labeledPHAN(phantom power)
andAUX(auxiliary power). The terminal is shipped in the AUX position. You must
verify that the jumper settings are set correctly for your configuration.
NOTE:
The power jumpers must be setonlyby qualified service personnel.
nPHAN (phantom power) should be selected when power is provided by the
PBX. When the jumpers are set to PHAN, in idle condition, less than one
Watt of power will be drawn from the switch. The power option resistors are
set to PHAN if each of the two jumpers covers the two top pins in each set.
(The bottom pin in each set is left uncovered.)
nAUX (auxiliary power) should be selected when power is provided in the
closet. When the jumpers are set to AUX, the 8510T will operate on a
nominal 40 or 48 Vdc, UL-listed Communications Circuit Power source.
The power option resistors are set to AUX if each of the two jumpers covers
the two lower pins in each set. (The top pin in each set is left uncovered.)
NOTE:
It is a requirement that 8510T voice only terminals in a multipoint
configuration (two or more terminals per por t) be auxiliary powered. If
used ONLY in a point-to-point configuration (one terminal per por t),
8510T terminals may be phantom powered. When used in a mixed
point-to-point and multipoint configuration, all 8510T terminals MUST
be auxiliary powered.
If a phantom powered 8510T is moved from an existing point-to-point
to a multipoint configuration, the power jumper must be changed from
PHAN to AUX, and the terminal connected to an auxiliary power
source. The terminal will still work in the PHAN mode, but the power
jumper must still be changed. Exceeding the phantom power capacity
will trip the breaker in the carrier, causing a loss of service.
