RS-232 AND DCP AT SEPARATE LOCATIONS

Figure 7-4 shows a case where one of the customer’s AUDIX systems is tied to a DCP switch and the other
tied to a non-DCP switch. The system located with the non-DCP switch is brand new, running R1V5 or
later software and equipped with a TN539 or TN539B for RS-232 access. The other system is running
R1V4 software and equipped with a TN366B (no RS-232 access). Since the DCP switch is equipped with
modem pooling, the modem pools are used to convert DCP into analog (t/r) for transmission to the other
AUDIX system. If the DCP switch did not have modem pooling, the customer should upgrade to R1V5 or
later software.
