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

asynchronous modem, communicate in ASCII code at 300 or 1200 bps (1200 only for DK8), have a standard typewriter-type keyboard, and display data via a CRT display or printer. A personal computer capable of emulating the described ter- minal with a communications software package (such as PROCOMM) may also be used. (See Paragraph 15 for compatible personal computers).

6.02Modem: For either system, the modem must be full-duplex asynchronous, operate at 300 or 1200 bps (1200 only for DK8) and have an RS-232 interface to connect with a terminal or PC (as described in Paragraph 6.01). It must interface with the public telephone network and be compatible with Bell 103 or 212 modem specifications.

6.10Set-up

6.11Refer to Figures 2, 3, and 4, and verify that the remote terminal is connected and set-up as follows:

1)Connect the terminal and modem together with the RS-232 cable.

NOTE:

If a personal computer is being used, connect the cable to the serial “COM” port.

2)Connect the modem line input to a CO/PBX line for access to the public telephone net- work.

3)Set the terminal and modem baud rate to match the DK16 PIOU(S) setting (300 or 1200 bps) or DK8 QSMU setting (1200 bps).

4)Set the terminal and modem for “Full Duplex” operation.

5)Set the terminal parameters to: Word length: Seven bits Stop bits: One

Parity: Even

6.20Remote Operation

6.21Automatic connection via ringing assign- ments: To establish communication between the

remote terminal and the IMDU or an external modem connected to a dedicated CO line, call the number of the system CO line assigned to ring the IMDU or the external modem via the remote termi- nal/modem set-up:

1)Observe the following:

When the CO line rings-in, it will connect to the IMDU or the external modem and the IMDU or external modem will respond by returning modem answer tone to the remote modem.

The remote modem will return modem tone to the IMDU or external modem and communication will be established.

When communication is established, the terminal will display: CONNECTED or COMMUNICATIONS (see Note in Para- graph 6.22).

2)To continue, Press CR and enter the security code per Paragraph 6.30.

6.22Manual connection via call transfer:

1)Using a telephone (at the remote location) that can switch to the terminal/modem, dial the number of a system CO line.

2)When the call is answered, request that it be transferred to station 619 if an IMDU is being used. For applications where an external mo- dem is connected to a dedicated standard telephone port, ask to be transferred to the intercom number assigned to the modem.

3)After the call is transferred and you hear modem tone from the IMDU or external mo- dem, switch the call from the telephone to the terminal/modem.

4)Observe the following:

When the CO line is transferred, it will connect to the IMDU or external modem.

The IMDU or the external modem and the remote modem will respond to each other with modem tone and communication is established.
