The Raven Digital Orderwire, 61610, allows voice communication through a 64kb/s digital service channel by including voice codecs in the Orderwire Terminal. The Digital Bridge module provides four 64kb/s RS-422 (V.11) ports for connection to the service channel equipment, as well as two analog VF ports, or one VF port and one or two RS-232 data ports, and the drop to the Orderwire front panel. The Digital Bridge performs the conference bridge function for all these signal paths digitally, eliminating additional quantizing noise at repeater and hub sites.

Orderwire decodes one to 20 unique DTMF address codes to ring the Orderwire and/or an optional Telephone Interface.
