3.1.2 On-air subscription of the CT-DECT device (PP) to the CT-DECT Case (8) (FP)
Î NOTES
● The on-air subscription is not part of the normal commissioning and operating procedure
for the system. It must be performed again only in the case a CT-DECT device (PP) that isn't
subscribed to the CT-DECT Case (8) has to be used in conjunction with the CT-DECT Case
(8).
● CT-DECT devices (PP) can be subscribed to only one CT-DECT Case (8), never to two or
more CT-DECT Case (8) units simultaneously.
Î NOTES
z Two ore more CT-DECT devices (PP) can never be simultaneously subscribed to the CT-
DECT Case (8), they must always be subscribed one after the other.
With two ore more CT-DECT devices (PP) it is recommendable to subscribe all devices one
after the other to the CT-DECT Case (8), because a device can be deleted (see 3.1.2.1 »Princi-
ple of subscription«).
z Comply with the instruction step sequence.
z After subscription all
new subscribed devices have to be switched off again.
The on-air subscription procedure is performed on the CT-DECT Case (8) and the CT-DECT devices
(PP) manually by means of operating elements. The CT-DECT Case (8) is the unit to which the maxi-
mum eight (8) CT-DECT devices (PP) of a system need to be subscribed to.
The CT-DECT Case (8) is equipped with two transceiver modules, the both subscription buttons (Fig.
3/b,c,i) and is able to control max. eight CT-DECT devices (PP). In each case max. four CT-DECT de-
vices (PP) are allocated to one transceiver module. Every four CT-DECT devices (PP) are assigned in
groups to the subscription buttons (figure 4/b, c). The function of the outside button (figure 4/i) is identi-
cal to that of the subscription button shown in figure 4/b.
3.1.2.1 Principle of subscription
Four CT-DECT devices (PP) can be assigned to each transceiver module in the CT-DECT Case (8).
The four CT-DECT devices (PP) assigned to a transceiver module should always be subscribed in
groups, but of course individually one by one.
Should a fifth CT-DECT device (PP) be subscribed to one and the same transceiver module, then the
CT-DECT device (PP) subscribed first would be deleted from the transceiver module’s memory (see
example in figure 5).
Î PLEASE NOTE:
The subscription procedure for a group of maximum four CT-DECT units (PP) which are sub-
scribed with the help of button “2” (figure 4/c) differs from the procedure when subscribing CT-
DECT devices (PP) with the “1/external” buttons (figure 4/b, i). The subscription procedure can
be performed while communicating without any need to switch off and open the CT-DECT Case
(8).
The procedure, applicable for subscribing maximum four CT-DECT devices (PP) with button “2”
(figure 4/c) is described in chapter 3.1.2.2 and for subscribing the other maximum four CT-DECT
devices (PP) with the help of buttons “1/external” (figure 4/b, i) in chapter 3.1.2.3.
