Real-Time Fax to Fax

Companies who have a high volume of fax trafﬁc with

partners or suppliers can reduce costs by deploying solutions

such as this. In Figure 6, a partner uses a standard fax

machine and sends a fax through a Cisco 3600 over a WAN

to another fax machine connected to a Cisco AS5300/Voice

Gateway through a PBX. A supplier uses a standard fax

machine and sends a fax through a Cisco 2600 over a WAN

to another fax machine connected to a Cisco AS5300/Voice

Gateway through a PBX.

The fax relay feature automatically determines when an

incoming call is a fax transmission, signals the receiving fax

machine over the IP network, and then accepts the fax

transmission for delivery only when the receiving fax

machine is on line. The end user can, therefore, be sure that

the fax is delivered.

The AS5300/Voice Gateway voice/fax feature card

interfaces with the source and target fax machines by

appearing to be a fax machine, using T.30 spoofing.

Incoming fax transmissions are demodulated before relay so

thatthe64K pulse-codemodulated faxcallconsumes only9.6K

or 14.4K of bandwidth across the data network per second of

fax transmission.
