Program 77-1 – Peripheral Options (Door Phones)

Program 77-1 Overview

This program performs the following functions:

♦Programs door lock relays

♦Assigns door phones/lock control units

♦Enables RMDS/IMDU built-in maintenance modems

♦Sets RMDS communications standard type

♦Enables DKi Admin Communications Protocol

♦Enables/disables door phone ring tone to external paging when system is in Night mode

♦Assigns a relay to operate with door lock function or external page for mute control

♦Assigns a relay to operate in one of two Night Transfer modes

♦Assigns a relay to operate in one of two applications

LED 20: Door Lock Time

The Door Lock Relay contact may be programmed to operate for either three or six seconds (applies to PIOU, PIOUS, PEPU, DDCB, and HDCB door lock controls).

LEDs 16~19: Port Number/Door Phone/Lock Control Units

Door phone/lock existence is defined by this program. The door lock option is set via Program 77-2.

♦DK424 and DK424i: Door phone/lock controllers (DDCBs and/or HDCBs) can only exist at Ports 004, 012, 020 and 028, and can only be installed on Circuit 5 of a PDKU, RDSU, PEKU and/or PESU. PDKUs and RDSUs support DDCBs, but not HDCBs. PEKUs and PESUs can support HDCBs, but not DDCBs. After assignment of a DDCB or HDCB, door phone numbers (#151~#159, #161~#163) effectively replace the station number assignment in Program 04.

Up to four DDCBs/HDCBs can be installed in a system with RCTUB, RCTUBA/BB and C/D, E/F and all BCUs; only 3 are allowed with RCTUA. They must be assigned a PDKU, RDSU, PEKU or PESU port number to operate (DDCB to PDKU or RDSU, and HDCB to PEKU or PESU). (See Program 79 and *79 for door phone ringing assignments)

Station PCBs that are connected to HDCB/DDCB door phones control boxes must be installed in lower slot numbers than Tie, DID, or Attendant Console PCBs.

♦DK40i and DK14: See port information on record sheet.

LED 15: RMDS Protocol

This program sets the RMDS communications standard type to CCITT/V.22bis (2400bps) or Bell 212A (1200bps). The standard set in this program must match the standard of the modem that will be used to communicate with the Strata DK RMDS.

♦If the RMDS modem standard should be 2400bps/CCITT/ V.22bis, turn LED 15 on; if the RMDS standard is a 1200 bps/Bell 212A, turn LED 15 off. Most Hayes compatible modems will function with either standard; check with the modem manufacturer’s documentation to verify which protocol should be used. When the system is initialized the Bell 212A (1200 bps) standard is set (LED 15 off).

♦IMDU can be 1200 bps or 300 bps as set by SW2 on the PIOU or PIOUS PCB; RMDS can be 1200 bps or 2400 bps as set in Program 76-2 and Program 77-1 LED 15.
