Connecting Fax to the ISDN (Digital Line)( DC440/432 )
Page 4-50
The Xerox DC440/432 is capable of working at a maximum
speed of 33.6Kbps across a good quality, analogue telephone
line to another fax machine with the same speed capability.
This speed is dependant upon the quality of the connection;
the poorer the quality, the slower the speed.
ISDN (Integrated Services Digital Network) is a digital
alternative to the analogue network.
To connect the Xerox DC440/432 to the ISDN requires the use
of a Terminal Adapter (TA) to interface between the machine's
analogue modem and the digital network. Once connected to
the TA, the machine will operate in the same way as if it were
connected to an analogue telephone system. Fax documents
can be sent or received in exactly the same manner as before.
Currently, a standard ISDN line is capable of providing two
separate telephone connections, each of which can have its
own telephone number. The Xerox DC440/432 can take full
advantage of this feature and improve its productivity by being
fitted with a second fax option and connecting both fax ports to
a TA that supports two analogue ports. It will then be capable
of simultaneously sending and/or receiving two faxes at the
same time over the same ISDN line.
Terminal Adapters are available on the open market from a
variety of suppliers. Contact your chosen supplier to arrange
purchase and installation if required. In view of the number of
alternative suppliers available, exhaustive testing of every
available TA has not been undertaken by Xerox and therefore,
Xerox does not recommend any particular supplier. Some
products have, however, been tested by Xerox and have been
found to be compatible with the DC440/432 fax. The local
Xerox representative will be able to supply details of these
products.
