AUDIX SYSTEM REQUIREMENTS FOR DCP MODE 1
Each AUDIX system requiring access to a switched 56 network must be running R1V5 or later software.
Each AUDIX system must also be equipped with a TN539 or TN539B ACCE circuit pack, the AUDIX
Networking Breakout cable (H600-331, Group 1 or Group 2). Also, if the RS-232 ports are to be used for
DCP Mode 1 transmission, an MPDM/M1* with an RS-232 interface card is required. If loopback testing
is to be conducted for an R1V5 or R1V6 AUDIX system, an MPDM/M1* with a V.35 interface card is
required. In addition, each AUDIX system must be within 5000 cable feet (1525 meters) of the switch’s
DCP interface.
