Limited-distance modem

553-3202-210 Standard October 1998
Modems are used to connect peripheral devices (terminals and printers) to
the IPE Module or the Application Module over long distances. Modems
are always DCE.
If a peripheral device is to be installed more than 15 m (50 ft) away from
the IPE Module or the Application Module, you will need to use a self-
powered limited-distance modem. The added range depends on the modem
you obtain. Limited-distance modems are recommended for use inside
buildings only. Nortel neither supplies nor recommends a particular make or
model of modem for this purpose. If diagnostic activities indicate that
problems exist with the modem, Nortel support personnel will recommend
that the customer call in service representatives for the modem equipment.
The following standards should be used when selecting a limited-distance
modem:
¥ 9600 bps
¥ 8 bits, no parity, 1 stop bit
