Programming - Toshiba Strata DK 280 Installation Manual

the RMDS and the IMDU operate with full-duplex
communication for remote maintenance (seven bits,
even parity, one-stop bit). If the IMDU is employed, a
dedicated CO line or standard telephone port is not
required. Connection of the remote maintenance
terminal is through existing system CO lines by
transferring the call by dialing # 19 or via Direct
Inward Dial (DID) CO lines (see Program *09 or 71-l
(l-3) to program RMDS or IMDU, DID extension
number). Refer to the RSIU, RSSU, PIOU or PIOUS
portion of Chapter 4-Printed Circuit Boards for
hardware installation and programming requirements.
External Maintenance Modem Installation:
Refer to
Figures 13-2 or 13-3, as applicable, and install the
external modem in accordance with the following
steps:
Note:
The Toshiba PPTC RS-232 modular-to-D925
adapter is factory configured for ASCII
terminal connection. Pins 2 and 3, and Pins 8
and 20 of the adapter must be reversed for
external modem connection (see Table 13-l).
1. Connect the modular cord from the RSIU, RSIS,
RSSU, PIOU, or PIOUS TTY port to the PPTC
adapter and then to the external maintenance
modem RS-232 25-pin connector.
2. Connect the external maintenance modem line-
side to a dedicated CO line (tip and ring) or to a
dedicated standard telephone port, tip and ring.
Refer to Chapter 7-Wiring Diagrams for
wiring/interconnecting details.
3. Set the PIOU or PIOUS SW2 switch to match the
modem or terminal baud rate:
Push in for 300 bps (baud rate indicator CD4 is lit);
let out (by pushing again) for 1200 bps (CD4 is not
lit).
4. Set the PIOU or PIOUS SW3 switch to the TTY
position.
Note:
The PIOU or PIOUS SW3 switch is set to the
MODEM position for IMDU operation only.
5. Set the P13 jumper plug on the PIOU to the BELL
configuration, or cut the W4 jumper on the PIOUS
(also for BELL configuration).

7.
Note:
The P13 (PIOU) and W4 (PIOUS) CCITT
configurations are not normally used in the
USA.
The communication parameters for the terminal
that will be used to communicate through the
external modem connected to the TTY port should
be set to seven-bits, even parity, one-stop bit.
Programming and system testing, via the external
maintenance modem, is described later in this
section. To access to the external maintenance
modem:
n If the modem is connected to a dedicated CO
line, call the CO line number to establish
modem communication.
4 If the modem is connected to a standard
telephone port, call a Strata DK280 CO line
that can be transferred to (or programmed to
ring) the standard telephone modem port to
establish modem communication. It is also
possible to establish communications by
calling in on a Strata DK280 DNIS, DISA, DID,
or Auto Attendant, CO line and dialing the
Directory Number of the modem connected to
the standard telephone port.
RMDSAMDU Maintenance Modem Installation:
If
RMDS or IMDU is used, install the RMDS unit per the
instructions provided in the RSIU section of
Chapter 4-Printed Circuit Boards.
13.4.4 Programming
If an IMDU or RMDS and/or 280Admin/Backup is
used, enable the IMDU or RMDS and/or
280AdmitVBackup in Program 77-l and Program 76
for RMDS.
If Remote Administration and Maintenance calls are to
connect to the IMDU or RMDS automatically, assign
the designated ground/loop start CO lines to ring the
IMDU or RMDS intercom or directory number (#19) in
Program 78 as required or assign DID/tie/DNIS CO
lines in Program *09 or 71-1 (1 - 3) (use standard
Strata DK280 programming procedures).
Program the security codes for Levels 1 and 2 as in
the Chapter g-programming Instructions. Reference
Program 00.
