Toshiba DK8, DK 16 manual Programming, 50 DK16 Imdu On-site Testing

REMOTE ADMINISTRATION AND MAINTENANCE PROCEDURES SECTION 100-816-600 MARCH 1993

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.

4.40Programming

4.41If 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.

4.42For DK8 only, turn LED 04 “ON” in Program 10-3to activate the QSMU for external modem operation.

4.43For 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).

4.44For 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.

4.50DK16 IMDU On-site Testing

4.51From 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
