APPENDIX A REMOTE PROGRAMMING

Remote programming capability has been incorporated in the NX-SERIES via the R-MMC serial port on the SMDR/R-MMC board option mounted on the base unit. This port is configured as a programming port only. The remote programming capability of the NX- SERIES can be used to add, delete, or modify a customer database. While remote programming gives added flexibility to the NX-SERIES, it is not possible to UP/DOWN load from or to a disk or tape. All NX-SERIES MMCs may be accessed via remote programming.

1. SITE REQUIREMENTS

1.1 CUSTOMER SITE REQUIREMENTS

Before using remote programming, the following requirements must be met at the customer site:

●Install the optional NX-SMDR/R-MMCboard in the base unit.

●MMC 80 Change Baud Rate: This MMC will set the baud rate of communication R-MMC port to match the customer site's modem. Baud rate selections are 300, 600, 1200, 2400, 4800, and 9600. 8 Data bits, No parity, 1 stop bit is default.

●MMC 80 Assign Remote Port: When remote programming is used,it must reference an installed NX24E keyset at the customer site. This keyset will be disabled for the duration of the remote programming session. When remote programming is not in use, this assigned keyset will function normally. The keyset port selection should be made considering minimal inconvenience to site personnel during programming sessions.

NOTE: There are no physical connections between the keyset and modem or keyset and communication port. The assigned keyset is used as a software reference point only.

●A customer-provided modem and cable connected to R-MMC comm port, as shown below:

●A voice grade dial-up line on which the modem may be called.

1.2REMOTE SITE REQUIREMENTS

●Personal computer (PC) with communication software that can emulate

VT-102 terminal.

NOTE: Since communication software can vary, no assurance can be made that every communications software package will work properly.

●Internal or external modem able to match baud rate speed with the modem at the customer site

●Voice grade dial line to call customer modem.
