dard (PP) has to be subscribed again to the CT-DECT device base (FP) according to the subscription

procedure.

Once the subscription procedure has been successfully concluded, the identity of the communication

participants is stored in the data memory of the device. The CT-DECT device standard (PP) stores one

CT-DECT device base (FP). The CT-DECT device base (FP) stores the last four successful subscribed

CT-DECT devices standard (PP).

8.3 On-air subscription

The on-air subscription procedure is performed on the CT-DECT Case and the CT-DECT Multi Stan-

dard (PP) manually by means of operating elements.

The CT-DECT Case is equipped with up to max. two digital transceiver modules (one in each CT-DECT

Conference (4)).

Each module is allocated a subscription button (Subscription „1“ and „2“) at the outside of the case

(Fig.3). The CT-DECT Case is able to control max. eight CT-DECT Multi Standard (PP). Maximal four

CT-DECT device standard (PP) are allocated in pairs to each transceiver module (= each subscription

button).

The CT-DECT Multi Standard (PP) should be divided into two groups of devices; around errors

when subscribed to avoid:

• Example group 1 – The four CT-DECT Multi Standard (PP) are allocated to subscription button »1«

(Fig. 3/e) at the CT-DECT Case. The subscription of the four CT-DECT Multi Standard (PP) to the

CT-DECT Case is carried out in groups but always one CT-DECT Multi Standard (PP) after the

other.

If a fifth

CT-DECT Multi Standard (PP) would be subscribed with the subscription button »1« (Fig.

3/e), the CT-CT-DECT Multi Standard (PP) of group 1 that was subscribed in first would be deleted

from the data base of the CT-DECT Case.

A CT-DECT Multi Standard (PP) that is deleted from the data base of the CT-DECT Case cannot

communicate any longer with the CT-DECT system. In this case the CT-CT-DECT Multi Standard

(PP) has to be subscribed again to the CT-DECT Case according to the subscription procedure.

Principle of subscription see section 8.2

• Example group 2 – The four CT-DECT Multi Standard (PP) are allocated to subscription button »2«

(Fig. 3/g) at the CT-DECT Case.

In the case that the CT-DECT Case is equipped only with one CT-DECT Conference (4) is only

the subscription button »1« active.

In the case that the CT-DECT Case is equipped with two CT-DECT Conference (4) are both sub-

scription buttons active.

Î Note

For the CT-DECT Multi Standard (PP) of the group 2 the subscription procedure is same like the

subscription procedure for the CT-DECT Multi Standard (PP) of group 1. The subscription pro-

cedure for the CT-DECT devices standard (PP) is described in sections 8.4...8.4.2.

Time Out

If no successful subscription was achieved after maximally 2 minutes, a »Time Out« occurs. The »Time

Out« is signalized by a tone sequence of 4 short deep tones in the CT-DECT communication set, which

repeats itself every 4 seconds.

After a »Time Out« all

CT-DECT Multi Standard (PP) of a group have to be subscribed again to the CT-

DECT Case. With a single CT-DECT Multi Standard (PP) only this single device has to be subscribed

again.
