The standalone version comes in a compact enclosure for desktop, shelf, rack, or wall mount
installations. It has a built-in AC or DC power supply and utilizes the same ELIMs and OLIMs as
the rackmount version.
On the front panel, the 2361 standalone modem includes the following:
•
1 DE 9 EIA-232 port
•
An MDM/TRM switch
•
In the MDM position, the modem transmits a modem signal via the serial port
(port is emulating DTE). The modem will therefore, support modem dial-up
connections.
•
In the TRM position, the port emulates VT100 terminal mode (port is emulating DCE).
•
A three-position loopback switch to select Local Loopback, Remote Loopback or off-
position. The switch will be operational only if the loopback mode is set in "hardware mode"
(See Chapter 7).
•
A Reset switch. This switch resets the processor without affecting the flow of the payload.
On the rear panel, the 2361 Standalone modem includes the following:
•
Major and Minor Alarm Input Connector
•
Major and Minor Alarm Output Connector
•
A Redundancy Cable used when the standalone modem is in redundant operation.
