Hardware installation
The following hardware is needed for Teleservice:
– An ELSA high-speed modem
– A 9-pin serial cable
– A 25/9-pin adapter
– A telephone cable
– A plug-in power supply unit
With most systems it is sufficient to connect the modem and system with the
serial cable. You should do this with the devices turned off. The following figure
shows where the connectors are located at the rear of the modem. To avoid con-
tact problems you should fasten the screws attached to the cable using a small
screwdriver.

Use the Western <-> TAE cable for the modem/telephone connection. The
Western connector is inserted in the modem and the TAE connector in the tele-
phone connection socket. Note that the TAE connector will only fit in a TAE
socket that has an N interface. A telephone is normally connected to an F inter-
face and is coded differently. There are also TAE sockets to which a telephone
and a modem can be connected. In this case, the modem is connected on the
left and the telephone in the middle.
