AT&T Remote Port Security Device Other, Modems, RPSD Lock or Key Administration Terminal

Other

Other dial-up port applications may be supported. To install an RPSD Lock device for these applications, locate the CO line used to service that port and install the Lock as you would for the remote maintenance and administration application.

Modems

The RPSD Lock works with any modem that may be used with the PBX. Similarly, the RPSD Key works with any modem that may be used with a terminal. Generally it is assumed that the modems in use are AT&T DATAPHONE® II 212 or 2224 modems.

RPSD Lock or Key Administration Terminal

The administration terminals for both Lock and Key are customer supplied. Any administration terminal for the RPSD Lock or for the RPSD Key must meet the following requirements:

■Asynchronous

■Full or half-duplex

■Standard RS-232 interface for connection to a DCE interface

■Any baud rate in the range 300-19.2K

■Any word size and parity

Connect the administration terminal to the Aux. Port of the RPSD Lock or Key via a standard RS-232 cable. Cabling is not supplied. The Aux. Port is the same port used if a printer is installed. You may wish to install a switch to make changing the Aux. Port connection easier.

The terminal should be initially set to 9600 baud and 8 bits, no parity. These are the factory default settings of the Lock and the Key. These parameters may subsequently be changed on both Lock, Key, and administration terminals.

RPSD Lock Administration Printer

The RPSD Lock requires a serial printer with XON/XOFF flow control.

Connect the printer to the Aux. Port of the RPSD Lock. Cabling is not supplied. This is the same port used by the administration terminal. You may wish to install a switch to make changing the Aux. Port connection easier.
