Overview
Introduction
Each modem supplied with Meridian Mail needs to be
configured before use. Modems must be configured so that the
baud rate matches that of the terminal and the CPU’s non-
volatile random access memory (NVRAM).
Connection speed
The modems are configured so that the connection from the
modems to Meridian Mail operates at a speed that is independent
of the telephone line connection. Therefore, an older 2400 bps
modem (such as the Ven-Tel 2400-33) can be set to communicate
with Meridian Mail at 9600 bps, while the telephone connection
operates at the maximum modem speed of 2400 bps.
Configuration
All modems, with the exception of UDS, need to be connected to a
terminal for configuration. If you wish, you can connect a modem
temporarily to the Meridian Mail administration terminal for
configuration, and move it to its permanent location afterward.
To configure a modem, you must
1. Temporarily connect the local administration terminal to
the local modem.
– For 2400 bps access, set the terminal to 2400 bps.
– For 9600 bps access, set the terminal to 9600 bps.
2. Send the appropriate commands to the modem.
Note: The UDS modem can be configured from its front panel
if you prefer.
Configuration of modems can vary slightly from one model to
the next. When you configure a modem, refer to the manual that
accompanies it as well as the procedures in this chapter.
ATTENTION
Use a remote modem or terminal that is operating at the
same speed as the Meridian Mail local administration
terminal you are accessing to prevent flow control problems.
