LED 14: RMDS or IMDU Modem

DK424 and DK424i: This program enables the built-in maintenance modem function: RMDS or IMDU. If LED 14 is off, the RSIU Port (1~4) which is set for TTY operation (Code 1 in Program 76-1) will operate as a local RS-232 maintenance port. If RSIU is not configured as TTY, then the PIOU/PIOUS/RSSU that has code 41 set in Program 03, will operate as a local TTY maintenance port.

Only one built-in modem RMDS or IMDU can be used in the DK424 or DK424i; if both are installed, RMDS will be accessed when a CO line direct rings the modem or is transferred to the modem by dialing &QI￿7UQ+￿￿￿.

♦DK40i: Turn LED 14 On if the optional PIOU or PIOUS has Remote Maintenance from the IMDU modem subassembly. If an IMDU is installed on a DK40i PIOU or PIOUS, it can be accessed by dialing station #19 (unless the access code prefix has been changed with Program 05).

Other system Programs that are related to the system modem are: Program 76, RMDS/TTY assignments on RSIU PCB; *-51~53, system CO line to modem ringing assignments; Program 71-1, DNIS line to modem ringing assignments; Program *09, DID line to modem ringing assignments; Program 77-1, LED 15, RMDS modem Protocol/speed assignments.

If a modem unit (RMDS/IMDU) is installed, it can be accessed by dialing Station #19 and can be assigned a DID extension number in Program *09 or in Program 71 (1~3). See Program 79 and Program *79 for door phone ringing assignments.

LED 10: DKi Admin/Backup

Enables the system to Upload/Download the RCTU RAM data base using Toshiba DKi Admin and/or DKi Backup software program. DKi Admin/Backup will automatically turn LED 10 On when the DKi Admin/Backup PC communicates with the DK424. LED 10 should be Off if the maintenance PC is using standard communication software (such as Procomm™) to program the DK424.

LED 08: Door Phone Ring On External Page

If a door phone button is pressed, a ring tone can be enabled or disabled to external paging when the system is in the Night mode. Activation of a Tenant 1 1LJKW￿7UDQVIHU￿ button is required to activate this feature. The Tenant 2~4 1LJKW￿7UDQVIHU￿a￿ buttons do not apply to door phones.

CO lines must be assigned to night ring over External Page (Program 78-1) to allow the NT relay to operate when incoming CO lines ring. See Programs 79 and *79 for door phone ringing assignments.

LED 07: Door Lock Relay/External Page Relay

A relay on the PIOU, PIOUS, or PEPU can be assigned to operate with the Door Lock function or with External Page for mute control. The door lock button (8QORFN￿'RRU￿a￿) is assigned in Program 39; the door lock activation time is assigned in Program 77-1. This door lock function is not associated with the DDCB or HDCB door lock, but is an addition to them.

This option applies to the PIOU/PIOUS/PEPU Door Lock Control 0 assigned to electronic or digital telephone buttons using Code 471 in Program 39; it does not apply to DDCB or HDCB Door Lock Control.
