Connecting the modem to the administration terminal
Introduction
Before use, configure the local and remote modems. The local
modem is the one connected to the Meridian Mail system. You
need to connect the modem to a VT220 terminal (the Meridian
Mail administration terminal) and send commands to the
modem as described. The remote modem is the one used by
offsite personnel to dial in to a Meridian Mail system.
Note: Before configuring the modem, you must first configure
the terminal to the desired speed. This determines the modem’s
default speed when resetting or powering up.
• For modem 2400 bps access, set the terminal to 2400 bps.
• For modem 9600 bps access, set the terminal to 9600 bps.
The baud rate of the Meridian Mail CPU can be set at either
2400 bps or 9600 bps. You must configure modems so the baud
rate matches that of the terminal and the CPU’s NVRAM using
the Change Speed utility. Access this utility through the System
Installation and Modification menu on the Install/data tape (on
the System Operation Utility menu), or in the System and
Feature Dependent Utilities on the TOOLS menu. After you set
the speed, reset the terminal and remote modem to match the
baud rate of the CPU card.

2 Plug the modem power cord into an AC receptacle.
3 Power on the modem.
4 Temporarily disconnect the administration terminal from the A/B
switchbox.
5 Connect the free end of the modem cable to the terminal so
you can configure the modem.
