FEC Loop (local)
RS Loop (local)
Internal IF Loop (local, Rx IF automatically tuned to match Tx)
Deframer/Framer Loop (remote)
Transmit CW (pure carrier)
Transmit alternate 1,0 pattern (for carrier suppression test)
Disable Reed-Solomon decoder corrections
3 independent changeover contacts:
Prompt Unit fault
Prompt Traffic fault (Tx or Rx)
Deferred Alarm (backward alarm, BER or Eb/No below user threshold)
Intel 8032 micro controller provides all M&C functions
Revised embedded software may be downloaded to FLASH memory
with modem still in equipment racks. No EPROMs, no opening of the
case.
Up to 10 different configurations can be stored & recalled from the front
panel or remote M&C
Clear & intuitive operator interface with plain English dialogue allows
fast and efficient configuration of modem. 80 Character, backlit, high
contrast, wide angle LCD 15 Key tactile full keyboard.
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 distant end
`over the satellite` M&C without cabling.
1:1 redundancy controller built in.`Y` cables passively split data,
maintaining impedances. L Band inputs/outputs are passively
split/combined outside the units. Offline unit tri-states data outputs &
mutes Tx carrier.
Stability: See Internal Reference / Station Reference (clocking section)
Switchable from front panel / remote M&C.
Tx: at rear N-Type to BUC +7dBm +/-2dB
Rx : at rear N-Type to LNB 0dBm +/- 0.2dB
Switchable from front panel / remote M&C.
Tx: 24V or 48V factory option (100W or 180W respectively)
Rx: 15V or 24V at 500mA
P310: Option for duplex FSK Communication with Paradise BUCs
(P314). Provides control of BUC from modem front panel or by remote
M&C via normal modem M&C ports. Includes control and monitoring of
all BUC parameters available over FSK, and option to provide closed
loop power control to BUC flange.
