REMOTE ADMINISTRATION AND MAINTENANCE PROCEDURES
SECTION 100-816-600
MARCH 1993
-7-
CD4 is lit); let out (by pushing again) for
1200 bps (CD4 is not lit).
NOTE:
The DK8 QSMU baud rate is always 1200 bps.
4) For DK16, 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) For DK16, set the P13 jumper plug on the
PIOU to the BELL configuration, or cut the W4
jumper on the PIOUS (also for BELL configu-
ration).
NOTE:
The P13 (PIOU) and W4 (PIOUS) CCITT
configurations are not normally used in the
USA.
6) The communication parameters for the termi-
nal 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. (300 or 1200 bps, see step 3
above).
7) Programming and system testing, via the ex-
ternal maintenance modem, is described later
in this section. Access to the external mainte-
nance modem is accomplished as follows:
If the modem is connected to a dedicated
CO line, call the CO line number to estab-
lish modem communication.
If the modem is connected to a standard
telephone port, call a STRATA DK CO
line that can be transferred to (or pro-
grammed to ring) the standard telephone
modem port to establish modem commu-
nication. It is also possible to establish
communications by calling in on a
STRATA DK DISA CO line and dialing the
intercom number of the modem connected
to the standard telephone port.
4.40 Programming
4.41 If an IMDU is used on DK16, enable the IMDU
in Program 77-1 (LED 14). If using an external
modem with STRATA DK16 or DK8, skip LED 14 in
Program 77-1.
4.42 For DK8 only, turn LED 04 “ON” in Program
10-3 to activate the QSMU for external modem
operation.
4.43 For DK16 only, if Remote Administration and
Maintenance calls are to connect to the IMDU
automatically, assign the designated CO lines to
ring the IMDU intercom number (619) in Program
78 as required (use standard STRATA DK16 pro-
gramming procedures).
4.44 For all cases of Remote/Local Maintenance
with a PC or ASCII terminal for either STRATA DK8
or STRATA DK16 program the security codes for
Levels 1 and 2 as in the Programming Procedures,
Section 200-816-300. Reference Program 00.
NOTE:
The security codes are initialized as “0000”.
These codes may also be changed via a local
or remote terminal.
4.50 DK16 IMDU On-site Testing
4.51 From any working station, test the functioning
of the IMDU for DK16.
1) Press the Intercom button.
Receive intercom dial tone.
2) Dial 6 1 9.
Receive modem tone from the IMDU after
a two-second delay.
3) Press the Speaker button to release.
4) Make an incoming call over each CO line that
is programmed to ring the IMDU (station 619).
Receive modem tone from the IMDU after
a two-second delay with each call.
NOTE:
This test checks basic programming and IMDU
operation, and should be completed before
