Group IV (G4) fax is an application that enables the system to use the advanced
Group IV fax equipment, one of the services accessible with Primary Rate
Interface (PRI) facilities. Group IV fax equipment provides several advantages:
■ High-speed transmission
■ High-quality laser reproductions
■ High-speed, high-capacity printing
■ Virtually error-free transmission
■ Office copying on a fax machine
Documents received from Group IV fax equipment are virtually perfect
reproductions of the original document. Therefore, any company involved in
graphic media (such as detailed engineering or architectural drawings or
advertising graphic layouts) is an ideal candidate for this application.
Depending on the fax machine’s interface, you can connect the Group IV
equipment in the following ways:
■ Direct RS-232 (the recommended method)
■ V.35 interface connecting to an ExpressRoute 1000 RS-232D interface
■ V.35 interface connecting to a ExpressRoute 1000 ISDN terminal adapter
Each configuration requires additional equipment.
