2. Overview
The TDM Headset Adapter (TDMHA) converts TDM digital data to analog audio data for use
with Standard type 2500 telephone headsets.
The TDMHA connections consist of one TDM 8-pin modular connector, one power
connector for an external power supply, and three 25-pair Amphenol connectors for headset
connections.
This is a conceptual wiring diagram for reference only. Each customer site will differ,
depending on existing wiring.
Note: To reduce noise interference induced into the analog wiring (the connections between
the TDMHA and the mod jacks for the operator's headset) keep the total length of this wiring
as short as possible. If you need more length, it is preferable to extend the length of the
cable between the DCP and the TDMHA (digital cable #883275R) up to the limit of 2000
feet. The standard length of the digital cable (#883275R) is 20 feet. Please contact your
Aspect Sales Person if you need a different length.

Each unit can be placed up to 610 meters away from the DCP
Note: The TDMA-00 Headset Adapter is intended to be used within the same building as

2.3 Switch Settings
Switch 1 (FREER) is used for factory testing only and must be set to the down position for
normal operation.
The up position will set the unit in a free-run (non clock extract) mode. This is useful for
testing the units without using a DCP. By connecting two of the units together, one in normal
mode and the other in free-run mode, the two units can communicate with each other. The
unit running in normal mode will extract the required synchronizing clocks from the free-
running unit and the two units will remain synchronized.
Headsets connected to the units will then function properly allowing audio communications
between the two corresponding headsets of each unit. For example, the headset connected
headset port # 5 on the normal unit will communicate with the headset connected headset
port # 5 on the free-running unit.
Switch 2 (A - U) is used to select between A-law and u-law compression. In the down
position A-law is selected and in the up position u-law is selected.
Switch 3 (BIAS) is used to select the bias voltage to the headsets. In the down position the
bias voltage is approximately 3.3 volts. This position is only used for headsets requiring
reduced bias voltage to function or for headsets that do not require external power. In the up
position the bias voltage is approximately 9.4 volts. The up position is the default setting for
the currently recommended Plantronics headset/amplifiers.

4-22-2008 3205-10084B Page 6
Switch 4 (SIDTN) is used to enable and disable the sidetone feedback. In the up position, a
small amount of the user’s voice is returned to the user’s ear. The down position will
disable* the sidetone feedback.
Note: *This switch can be disabled with the internal enable/disable switch jumper.
Switches 5 and 6 (XSET2, XSET1) are used to set the transmitted output audio level from
the headset microphones to the CODECs. This is useful for headset amplifiers that do not
have an adequate range of adjustment. Caution should be exercised with the settings of
these switches. Crosstalk and noise, from the cabling, may be noticeable in longer cables
with the higher level switch settings. For the best results, adjust the headset amplifier
microphone gain adjust to the highest usable setting and then adjust the (XSETx) switches
for the lowest usable level. This will reduce the cable noise and crosstalk to a minimum.
Note: This switch can be disabled with the internal enable/disable switch jumper.
XSET2 XSET1 AUDIO GAIN
UP UP = + 4 DB
UP DOWN = 0 DB default *
DOWN UP = - 5 DB
DOWN DOWN = - 10 DB
* Note: This is the value that will be observed when the internal jumper is in the disable
switches position.
Rotary switch (RSET) is used to set the receive input audio level to the users headsets. This
is useful for headset amplifiers that do not have an adequate range of adjustment. Caution
should be exercised with the settings of these switches. Crosstalk and noise, from the
cabling, may be noticeable in longer cables with the higher level switch settings. For the
best results, adjust the headset amplifiers earphone volume adjust to the highest setting
and then adjust the (RSET) switch for the lowest usable level. This will reduce the cable
noise and crosstalk to a minimum.
Note: This switch can be disabled with the internal enable/disable switch jumper.
RSET AUDIO GAIN
0 = - 4 DB
1 = - 2 DB
2 = 0 DB default *
3 = + 2 DB
4 = + 4 DB
5 = + 6 DB
6 = + 8 DB
7 = + 10 DB
8 = + 12 DB
9 = + 14 DB
* Note: This is the value that will be observed when the internal jumper is in the disable
switches position.

Headset Adapter Installation Guide
3. Enable Switches Jumper
This jumper is used to enable or disable the externally accessible audio gain and side tone
switches. This is useful for countries that restrict end user accessible adjustments to the
audio levels over their Telco networks. This is a 3 pin header with a movable shunt
connector. When the shunt is placed across pins 1 and 2, the SIDTN, XSET2, XSET1 and
RSET switches are disabled and serve no function. In this state there is no side tone and
the transmit and receive gains are set to 0 DB (the default settings). When the shunt is
placed across pins 2 and 3, the SIDTN, XSET2, XSET1 and RSET switches are enabled
and will function as described in the SWITCH SETTINGS section of this document.

4. Rules for Cabling the TDM Headset Adapter
The TDM Headset Adapter shall be placed as close as possible to the agent positions
where headsets are employed. The recommended cable length between the TDMHA-00
Headset Adapter and the Agent Position is approximately 110 feet. The maximum length of
all combined cables between the TDMHA and the agent position where the headset is
employed shall be no more than 310 feet. The stated distance limitations are required for
good reliable agent position headset audio.
Category 5 (or better) twisted pair cables shall be used between the TDMHA and the agent
position headset.
The use of flat non-twisted silver satin telephone cables shall be avoided. They offer poor
isolation between transmit and receive pairs. If flat silver satin telephone cables are
employed, the physical length shall be no longer than 6 ft. If coach mode is intended, the flat
silver stain cords shall not to be used.
Category 5 (or better) twisted pair cables shall be used between the DCP and the TDMHA.
The maximum length of this cable shall be 2000 feet.
All TDMHA cables shall be isolated from other electrical wiring such as fluorescent lighting
fixtures; power transformers, transmitters and other electrical appliances that might cause
interference with the functionality of the TDMHA.

The total wire length shown shall not exceed 310 feet. All items are customer supplied.
Note: To reduce noise interference induced into the analog wiring (the portion of the wiring
between the headset adapter and the mod jack for the agent’s headset) keep the total
length of this wiring as short as possible. If you need more length, it is preferable to extend
the length of the cable between the DCP and the TDMHA (digital cable # 883275R) up to
the limit (2000 feet).
