Connecting Fax to the ISDN (Digital Line) - Embedded Fax (DC440/432/430/425)

Fax

The Xerox DC440/432/430/425 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 DC440/432/430/425 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 DC440/432/430/425 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 DC440/432/430/425 fax. The local Xerox representative will be able to supply details of these products.
