6 Remote Access and Control
Overview
Ports The ES648 control unit provides remote access ports that can be used in
different ways:
• With a Lucent Technologies proprietary modem that plugs into the
control unit card, i.e., the Internal Modem – Circuit Pack EMC1
(ES648BZ)
• With an External Modem – RS-232 Connector
• To communicate with a terminal device, such as a computer, using
either an RS-232 or RS-485 connection.
The following list is the order of precedence for the port types:
– RS-232 Local
– RS-232 External Modem
– Internal Modem (Lucent Proprietary Modem – EMCI, available
in North America only)
– RS-485
If a terminal is connected to the Local RS-232 connection, then the
control unit communicates with the device connected to the RS-232
connection even if an internal modem card is plugged into the control
unit.
For the RS-485 connection to operate, the cables to the RS-232 local
connection and external modem ports must be disconnected, and the
Internal Modem (EMCI) must be removed from the control unit.
