2.4.3 Auxiliary Data Connections
There are 5 auxiliary data connections for LYNX.sc as shown in Figure 2-4 through Figure 2-6.
VF
This connector is used to link two LYNX.sc radios at a repeater site for Orderwire
operation. This would allow orderwire "telephone" calls to and from any point in the
LYNX.sc network.
The LYNX.sc orderwire circuit can also be connected to other existing
orderwire networks. See Section 3.14.1 for details.
ALARM
This connector is used for monitoring alarms electrically. The alarm connections are
essentially the same as described for the front panel, however instead of LED
operation, alarm status is provided electrically by means of TTL and Form C relay
connections. The TTL and Form C relays can be connected to other transmission
equipment for monitoring alarm status locally or remotely.
DIAG-
NOSTICS
This is a serial interface port (RS-232 or RS-422, 9600 baud) to the LYNX.sc radio.
This port provides maintenance information about the LYNX.sc radio(s) to a
connected computer or terminal. This port is typically used for maintenance and
troubleshooting or connection to network management systems.
AUX
DATA
This is a serial interface port (RS-232 or RS-422, 9600 baud) which allows the user
to connect auxiliary serial data from one point in the radio network to another. This
facility can also be used for bridging the DIAGNOSTICS port for remote alarm and
status monitoring (TBOS network management) or for connecting other equipment's
serial alarm information. It can alternatively be used for separate data connection for
LANs or other serial devices.
PROTECT
This is a port used to connect the LYNX.sc radio to an additional unit for Monitored
Hot Standby (MHS) or Space Diversity (SD) configuration. The MHS and SD units
can be configured to provide protection to the LYNX.sc radio by means of a "back-
up" radio which would switch-in should there be problems with the primary radio or
the radio path.
The protect feature is not available at the time of the printing
