System & Station

Program 20 – Computer and Data Interface Unit Configuration

LED 06: DTR Pulse

LED 06 should always be Off.

LED 06 should be off for all PDIU-DS, RPCI-DIs, or PDIU-DIs. (Refer to Chapter 10 – Peripheral Installation for more PDIU-DS/modem pool information).

LED 05: Auto Pause Behind PBX

Turn LED 05 On to enable Auto Pause Behind PBX. This inserts the Auto Pause after a Centrex or PBX access code is dialed by a DIU or RPCI. A CO line must be assigned in Program 42-0, and must have an access code assigned in Program 42 (1~8). Pause time is determined by Program 12-

3.Also, when Auto Pause Behind PBX is enabled, the Auto Pause is inserted after the CO line access code is dialed (by the DIU).

If the system CO lines are connected to a PBX, Centrex, or a Central Office that is slow to return dial tone after seizure, enable Auto Pause Behind PBX to insert a pause before and after the PBX or Centrex access code is dialed by the DIU or RPCI. Also, light LED 05 to automatically insert a pause before network telephone numbers are autodialed by DIUs or RPCIs.

LED 04: PDIU-DS or PDIU-DI/RPCI-DI Connection

Set LED 04 On if a PDIU-DS is connected to the digital port.

Important! If LED 04 is turned on for a telephone port, that telephone cannot be called.

Set LED 04 Off if a PDIU-DI or RPCI-DI or any type of telephone is connected. In this case, the digital telephone supporting this PCB may require the Data Call (DATA), Data Release (DRLS), and/or Modem buttons assigned in Program 39. Also, if an RPCI-DI is used in the Application Program Interface (TAPI) mode only, and not the Data Switching mode, set LED 04 Off.

Note The pause length is set in Program 12-3, and lines behind PBX/Centrex are assigned in Programs 42-0 and 42-1~8.

LED 03: RPCI/PDIU-DS to Modem Connection

If a PDIU-DS is connected to the digital port, identify whether the RPCI/PDIU-DS is connected to a modem (LED 03 On) or not connected to a modem (LED 03 Off). If not connected to a modem, the connected device can be a DCE or DTE. This feature is not necessary for RPCI/PDIU-DIs, because they are not normally connected to modems.

LED 02: AT Commands and Result Codes

Enable this feature (LED 02 On) if the RPCI or DIU must respond to AT commands and return result codes in the Data Switching command mode. RPCI/DIU “AT” dialing commands and “result” codes are listed in the RPCI-DI and the Data Interface User Guide.

If the DIU is connected to a modem, LED 02 should be On. If the RPCI/DIU is connected to a printer, LED 02 should be Off. If an RPCI-DI is used in the Application Program Interface (TAPI) mode only, and not the Data Switching mode, this option is not applicable.

If the feature is not enabled (LED 02 Off), the RPCI/DIU only responds to AT dialing commands (ATDT, ATD, and ATDD) and does not return result codes. If the DIU is connected to a terminal or a personal computer with communication software, LED 02 should be On.

LED 01: RPCI and PDIU Connection

Enable this feature (LED 01 On) if there is a PDIU-DI, RPCI-DI or PDIU-DS connected to the digital port. Each RPCI-DI or PDIU-DI uses the same digital port as the telephone it is attached to. This feature is not applicable if an RPCI-DI is used only in TAPI, and not DIU mode.
