Can analogue devices such as Group 3 fax machines be used over Mobile ISDN?
The 3.1kHz audio service enables high-quality analogue connections. Group 3 fax machines for example can be plugged in via the analogue (RJ-11) port on the GAN terminal or an external ISDN terminal adapter (TA) and used to send and recieve faxes at the full Group 3 rate (up to 14.4 kbit/s). Similarly computers running fax software are also compatible with 3.1 khz audio. A number of analogue devices can be connected to a single terminal, each with its own unique telephone number.
