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).
