Common Specifications
Parameter
Modem
Loop-backs
Interface Loop (Local and Remote)
Internal IF loopback (local, automatically matching Rx
IF frequency to Tx)
Test Modes
Transmit CW (Pure Carrier)
Transmit Alternate 1-0 Pattern
Alarm Relays
4 Independent Change-Over Contacts:
Unit Fault,
Rx Traffic Fault
Tx Traffic Fault,
Deferred Alarm (backward alarm, BER or Eb/No
below user set threshold)
Embedded Software
Revised embedded software may be downloaded into
non-volatile memory via Ethernet port (or USB) with
modem remaining in equipment rack.
Configuration Memories
100 configurations can be stored and recalled from the
front panel or remote M&C. Memories can be labeled
with text string to aid identification.
User Interface
Clear and intuitive operator interface with plain English
dialogue (other languages supported). Graphic
display, backlit, high contrast, wide angle LCD. 17 key
tactile full keyboard.
Remote Monitor and
Control
For multi-drop applications, RS485 interface.
For direct to PC applications, RS232 interface (front
panel selectable). M&C port may be directly internally
linked to ESC port for “over-the-satellite” M&C without
cabling.
Ethernet (10/100/1000 BaseT) via RJ45, embedded
Web server, SNMP agent V1, V2c, V3.
Redundancy Features
1:1 redundancy controller built in. “Y” cables passively
split data maintaining impedances. IF inputs/outputs
are passively split/combined outside the units. Off-line
unit tri-states data outputs and mutes Tx carrier. 1:N
(up to 16) supported for many interface types.
Monitor
0 to 10V analogue output (Signal level, Eb/No, or Rx
offset frequency) on Alarms & AGC connector
Mechanical
1U chassis, 410mm deep, excluding front panel
handles and rear panel connectors and fans
.
Weight
3.5 Kg
Power Supply
90 to 264VAC, 1A @100V, 0.5A @ 240V, 47 to 63Hz
Fused IEC connector (live and neutral fused); 24V and
48V DC options
