AnaCom's
Protection Switch System provides a high reliability
1 for 1 Hot-Standby configuration for the ANASAT C
and
Ku-Band transceivers. The Protection Switch System
is ruggedly built for continuous outdoor duty in all
types of environments. The Protection Controller is
designed for simple, intuitive operation. TX and RX
switches function independently.
The Protection System
consists of a Protection Controller out-door box,
and WR-229 and WR-137 waveguide switches for C-Band
applications, or a pair of WR-75 waveguide switches
for Ku-Band applications. Both switches include
waveguide terminations for the off-line equipment.
Only a single RS232/1485 interface cable is required
to interface to indoor computer/dumb terminal.

PROTECTION
SWITCH SYSTEM
Compact,
Functional Design
AnaCom's Protection
System integrates all necessary functions into a
small, highly integrated outdoor package which is
designed to give highly reliable service in a wide
range of environments.
The Protection
Controller is fully contained in a single, small out
door box with manual over-ride controls. Although
normally intended for un-manned, automatic operation,
the switch can be locally (or remotely) over-ridden to
place a particular TX or RX switch (or both) on line
and defeat the normal "switch-on-alarm" mode of
operation. A single push-button (or remote command)
returns the unit to completely automatic operation.
BITE
Facility
To improve and simplify maintenance routines, an
external terminal (or computer) can be connected to
monitor a number of critical parameters without use of
additional test equipment. These include:
|
Transceiver alarm status (TX, RX; A and B) |
|
Switch alarm status |
|
Switch position status |
Controllable functions
from the terminal include:
|
Force TX switch to
the A side |
|
Force TX switch to
the B side |
|
Force RX switch to
the A side |
|
Force RX switch to
the B side |
|
Restore AUTOmatic
operation |
Comprehensive Monitor & Control
The Monitor and Control feature allows you to monitor
and control the Protection Controller and both
transceivers on the same RS232/RS485 M&C bus.
An MS DOS based
Software provided with each Protection Switch for use
in combination with a PC for monitoring and
controlling both transceivers and the Protection
Switch System from one computer display. Only one
RS-232/RS485 cable is required from the computer to
the outdoor equipment.
Benefits
| High
reliability with independent TX and RX
switching |
| Simple,
intuitive operation requires minimum
training |
| Front
panel allows for direct manual switching |
| "Last
Touch" controls allow for remote
configuration or local (manual)
configuration |
| Simple,
low cost installation using a minimal
number of cables |
