The telephone system can be operated as follows:

The telephone radio signals are transmitted and received by the telephone antenna (A2/22) and amplified with the portable CTEL antenna amplifier (A28/2). The display of the COMAND operating, display and control unit (A40/3) shows when the telephone is in its ready status the destination field strengths in 5 grades.

All control signals and useful signals (e.g. sound signals with hands-free system activated) are transmitted via the Media Oriented System Transport (MOST). For this reason, the portable CTEL (A34/6) requires the Universal Portable CTEL Interface (UPCI [UHI]) control unit (N123/1) as an interface to the Media Oriented System Transport (MOST).

The COMAND operating, display and control unit (A40/3) has the following telephone functions:

  Telephone antenna, location/task   GF82.62-P-4105PP
  UPCI control unit (Universal Portable CTEL Interface), location/purpose with code (388) portable cellular telephone, UPCI system GF82.70-P-5100PM
