2. Description
2.1 General
This duplex communication system (see example Fig. 1) is used for aircraft push-back. The tug driver,
two wing walkers and marshalling agent wear headsets in conjunction with Transmitter/Receiver Units
»CT-GateCom II.24/Multi«. The four headset wearers outside the aircraft can communicate with one
another. The tug driver is able to communicate with the flight deck via the Aircraft Interface that is
connected to the aircraft intercom on the outside of the aircraft.
The Aircraft Interface contains the Transceiver Module CT-DECT-I24.
The range depends on the local circumstances. Protection against eavesdropping is ensured by the
digital design. Channel selection is effected automatically.
2.2 Communication circuits
Wing walkers
The two wing walkers can communicate with each other, with the marshalling agent, and with the tug
driver. The wing walkers are not able to speak to the flight deck. But they are able to hear the
communication between the flight deck and the tug driver.
Marshalling agent
The marshalling agent can communicate with the two wing walkers and with the tug driver. He is able to
hear the communication between the flight deck and the tug driver. When the tug driver speakes to the
flight deck the marshalling agent can also speak to the flight deck as long as the microphone switch at
the left headset muff of the tug driver is in position »PTT« or »HOT«.
Tug driver
The tug driver can communicate with the two wing walkers, with the marshalling agent, and with the
flight deck. When he communicates with the wing walkers and/or with the marshalling agent the flight
deck doesn‘t hear this communication. When the tug driver communicates with the flight deck the two
wing walkers and the marshalling agent will hear this communication also.
The tug driver is the only person who is able to control the communication with the flight deck.
Flight deck
The flight deck can only communicate with the tug driver. The two wing walkers and the marshalling
agent can hear this communication as well. When the tug driver speakes to the flight deck the
marshalling agent can also speak to the flight deck as long as the microphone switch at the left headset
muff of the tug driver is in position »PTT« or »HOT«.

knob).
After Switching on the connection synchronization between Transmitter/Receiver Unit and Aircraft
Interface is effected automatically.
Synchronization: A click is audible in the headset connected to the Transmitter/Receiver Unit
approximately 10 seconds after switching on. The synchronization procedure then begins, i.e. the
previously switched on Aircraft Interface seeks its Transmitter/Receiver Unit. This synchronization
procedure can last approx. 30 seconds. Upon completion of synchronization – i.e. the Aircraft
Interface has found its Transmitter/Receiver Unit – a high double-beep P-tone sounds in the
headset, indicating that the Transmitter/Receiver Unit and the Aircraft Interface are ready for
operation.
c. At the Transmitter/Receiver Unit set the On/Off switch and volume control (rotary knob) to mid-
position. Later, on voice reception, adjust the desired speaker volume for your headset. Do not set

7. On-air subscription
7.1 General
Î NOTES
zThe on-air subscription is a procedure which has to be performed once only ex-works.
It must be performed again only in the case of an error or if another Transmitter/Receiver Unit
CT-GateCom II.24 will be used in conjunction with the Aircraft Interface. The Aircraft Interface
contains the Transceiver Module CT-DECT-I24.
zIn the following the on-air subscription is described for the Aircraft Interface in conjunction
with Transmitter/Receiver Units CT-GateCom II.24/Multi. The on-air subscription for the
Aircraft Interface in conjunction with Transmitter/Receiver Headsets CT-GateCom II.24 is
carried out analogous and in the sequence as described in sections 7.2...7.4.
The subscription procedure is performed on the Aircraft Interface and the Transmitter/Receiver Units
manually by means of a procedure carried out by the operator.
The Aircraft Interface is equipped with two radio modules. The four Transmitter/Receiver Units are
equipped with one radio module each. Each unit (radio module) has its own identification number.
A max. of four Transmitter/Receiver Units (in two groups) is allocated to the two radio modules in the
Aircraft Interface. The Aircraft Interface is the base unit and the Transmitter/Receiver Units are
subscribed to the Aircraft Interface. First of all an allocation must always take place between the Aircraft
Interface and the Transmitter/Receiver Units.
Ex-works the four Transmitter/Receiver Units are divided in two groups as follows
(Fig. 2/i and h):
yGroup 1 – Transmitter/Receiver Units with red colored push-button bank for tug driver and
marshalling agent. The subscription is carried out by means of the red subscription button
»T« (Fig. 2/i) for group 1 at the Aircraft Interface
yGroup 2 – Transmitter/Receiver Units with black colored push-button bank for wing walkers.
The subscription is carried out by means of the black subscription button »W« (Fig. 2/h) for
group 2 at the Aircraft Interface
Other allocations in pairs can be carried out later by the customer. Please heed that the subscription of
the Transmitter/Receiver Units in conjunction with the Aircraft Interface is always carried out in pairs.
If a third Transmitter/Receiver Unit is subscribed to one of the two groups of the the Aircraft Interface,
the Transmitter/Receiver Unit that was subscribed first is deleted from the data base of the Aircraft
Interface.
Once the subscription procedure has been successfully concluded, the identity of the communication
partners is stored in the data base of the Aircraft Interface and of the Transmitter/Receiver Units. A
Transmitter/Receiver Unit stores one Aircraft Interface, the Aircraft Interface stores in pairs up to four
(2 x 2) Transmitter/Receiver Units.
Time Out
If the Aircraft Interface or a Transmitter/Receiver Unit is set to subscription mode and this is terminated
or not completed after 2 minutes without the subscription procedure having been successfully
concluded a »Time Out« occurs. The »Time Out« effects that in the Aircraft Interface the available data
bases for a max. of two stored Transmitter/Receiver Units of a group and in the case of the
Transmitter/Receiver Unit the available data base for the stored Aircraft Interface are deleted. After a
»Time Out« the subscription procedure for the Aircraft Interface and for both Transmitter/Receiver Units
must be restarted.
11
7.2 On-air subscription of the first Transmitter/Receiver Unit of group 1
Î NOTE
zThe Transmitter/Receiver Units are subscribed in pairs (group 1 and 2 see section 1), but one
after the other, to the Aircraft Interface. First the two Transmitter/Receiver Units of group 1
are subscribed one after the other to the Aircraft Interface and then the two
Transmitter/Receiver Units of group 2 are subscribed one after the other to the Aircraft
Interface.
zTwo Transmitter/Receiver Units can never be simultaneously subscribed to the Aircraft
Interface. The Transmitter/Receiver Units must always be subscribed one after the other to
complete a group.
zFor subscription the Aircraft Interface must always be switched on before the
Transmitter/Receiver Unit.
a. Connect the first headset of group 1 to the first Transmitter/Receiver Unit of group 1 (identifiable by
the red colored push-button bank) via the connecting cable and plug of the headset. Open the
carrying bag for the Aircraft Interface by means of the zip.
b. At the Aircraft Interface press the red subscription push-button »T« (Fig. 2/i) for group 1, keep the
red push-button »T« pressed and switch on the Aircraft Interface by means of the green push-button
ON (Fig. 2/e). The control lamp (Fig. 2/f) illuminates. After switching on keep the red subscription
push-button »T« pressed for at least 10 seconds. Than immediately carry out step »c«.
c. At the first Transmitter/Receiver Unit group 1 with red colored push-button bank press the
subscription button 1 simultaneous with subscription button 5 located at the begin and end of the
push-button bank. Keep the two push-buttons pressed and switch on the Transmitter/Receiver Unit
by means of the On/Off switch and volume control (rotary knob). After switching on keep the two
push-buttons pressed for at least 10 seconds.
The subscription procedure on the Transmitter/Receiver Unit has to be started within 2
minutes after the subscription procedure on the Aircraft Interface was started, otherwise a
»Time Out« may occur (see section 7.1).
After approx. 30 seconds a high double-beep tone can be heard in the headset. This indicates that
the on-air subscription has been successfully completed. A second high double-beep tone finally
reports that the Transmitter/Receiver Unit has synchronized itself with the Aircraft Interface.
7.3 On-air subscription of the second Transmitter/Receiver Unit of group 1
a. Switch off the Aircraft Interface with the red push-button OFF (Fig. 2/g). The control lamp (Fig. 2/f)
extinguishes.
b. Connect the second headset of group 1 to the second Transmitter/Receiver Unit of group 1
(identifiable by the red colored push-button bank) by means of the connecting cable and plug of the
headset. Ensure that the Transmitter/Receiver Unit is switched off. The on/off switch and volume
control (rotary knob) must be set to OFF .
c. Repeat the subscription procedure for the Aircraft Interface and the second Transmitter/Receiver
Unit of group 1 as described in section 7.2, steps »b« and »c«, for the Aircraft Interface and for the
first Transmitter/Receiver Unit of group 1.
7.4 On-air subscription of the first and second Transmitter/Receiver Unit of group 2
The subscription procedure for the Aircraft Interface and the two Transmitter/receiver Units of group 2
(identifiable by the black colored push-button bank) is carried out as described in sections 7.2 and 7.3
for the two Transmitter/Receiver Units of group 1. At the Aircraft Interface the black subscription push-
button »W« (Fig. 2/h) for group 2 is used instead of the red push-button »T« for group 1 (Fig. 2/i).
