Introduction
TheAirLink Pro T1/E1 Rack Mount ASCII terminal and Network Management
ports are EIA/TIA-232 interfaces that allow terminal devices or personal
computers to control and monitor AirLink Pro T1/E1 Rack Mount operation at
either end of a point-to-point link. Each EIA/TIA-232 connection can be either
a direct connection (device to port), or an indirect connection (device to modem to
port) for dial-up operation.
The Network Management (Modem) Port is available only on the Access Unit,
and uses a different physical port from the Terminal port. However, when the
network management port is connected (and dialed-up, in the case of a modem
link), commands issued from that port, along with the responses from the
terminal port, are duplicated at the Network Management port.
The modem support may be configured to work in any of these five modes:
DISABLED The port is completely disabled and it will not
respond to user commands or connection
indications from the modem.
DEDICATED The port behaves exactly as the Terminal
port; all commands and responses taking place
on that port are duplicated on the modem port.
ANSWER The modem port remains idle (does not respond
to user commands) until it receives a dial-in
indication from the modem.
DIALOUT ONLY The modem port is used only for dialing-out to
report alarms.
DIALOUT/ANSWER Combines the functionality of the ANSWER
and DIAL-OUT modes.
After the completion of a dial-out, a connection announcement is printed at the
remote end. This announcement identifies the unit type, the site name as
configured by the user, the date and time, plus a copy of the alarm text message.
