5.2.5 Call-note

As soon as the code protection against unauthorized access to the data terminals is

activated, a call-note can be made. At the call-note, instead of the code during Login, the

command for call-note including indication of the telephon register number 0-3 of the

device, as well as a 8-digit acknowledgement recognition is transferred. Then the

ComuCont Dual automatically hangs up and, at the earliest after 5 seconds, starts the

recall to the telephon number of the selected register.

5.2.6 11bit Data transmission

Besides the standard settings of 10 bits per signal (8.1,None or 7,1,Odd) signals of 11 bits

can be transferred, too. Thus, the settings such as 8 Data, 1Stopbit and Even Parity to the

data terminal are possible. The transmission via the radio path/permanent net path is

however only possible with 10bits. Therefore reaching 11bit signals without Parity with

8.N,1 are retransmitted by the radio-module.

5.3 Working mode conditions of the device

Information on the below indicated descriptions:

Disconnect: There is no phone connection to another modem.

Connect: There is a connection to another modem.

Transparent: Data are directly (with conversion of the Baudrate and data-, Stop-, and

Paritybits) retransmitted.

Parameterize: All data are intercepted and evaluated by the processor.

5.3.1 Disconnect-Transparent-Mode

After the net-on, the ComuCont Dual is in the Disconnect-Transparent-Mode, which

means, that all signals transferred to the local digital trunk interface are automatically

retransmitted to the integrated modem of the ComuCont. In the same way, the Modem-

response is again transmitted via the interface.

Thus, the modem can be additionally parameterized with AT-commands. This function

may only be done by trained personnel!

The parameters (Baudrate, Data bits, Parity, Stopbits) of the serial digital trunk interface

can be variable adjusted (see parameterization-mode).

Note: In the Disconnect-Mode no codes are active.

Via the signal sequence „$$$“, which has to be entered within one second and a signal stop

of more than one second before this sequence, you get into the Disconnect-

Parameterization-Mode.
