This handbook describes how to install and configure the
P300 Series Satellite Modems. This includes the original P300, the P300 Turbo,
P310 L-Band and P311 mixed L-Band/IF Modems. Where ever reference is made to
the P300 or P300 Series modem it applies to all products unless specifically
noted.
Paradise Datacom P310 VMUX
The P300 Series may be supplied equipped with different
feature sets to suit different applications. This means that the mix of
features available in any modem (such as Drop/Insert, IDR framing etc) may be
tailored to suit any user requirement, however typically they are grouped into
one of four standard configurations as follows:
- P300 / P310-VSATFeatures for use in VSAT applications.
- P300 / P310-IBSFeatures for IBS/SMS use (or thin route IDR
below T1) services.
- P300 / P310-IDRFeatures for IBS/SMS AND IDR services (IDR at
T1 or greater).
- P300 / P310-TCMFeatures for use in TCM, TCM/IDR, IBS/SMS and
standard IDR services.
The table on page 11 summarises the different features, and
which features are available in the four standard configurations.
The P300 Series Modems are designed for operation in a
typical ground station environment, providing a data link between
geographically distant sites via satellite. Like its predecessors, it is
physically small, light, and of rugged construction, allowing it also to be
used in mobile and fly away terminals.
The P300 Series provides a data port on the terrestrial side
which provides RS422, V.35, and RS232 software selectable interfaces on both 25
pin EIA 530 and 37 pin RS449 connectors. Optional G.703 interfaces provide
either a T1 or E1 (1544kbps or 2048kbps) G.703 interface in addition to the
standard three interfaces. The modem couples into the ground station up / down
converter chains on the RF side at either 70MHz or, if the Wideband IF feature
is available (standard on P300-IBS and above), 140MHz. The status of a unit is
available externally on `form c` relay outputs designed to connect to station
monitoring system. The modem also provides a complete remote Monitor &
Control (M&C) port, allowing the status to be remotely monitored and the
unit controlled or the configuration changed.
If Async ESC feature is available (standard on P300-IBS and
above) the modem can provide an asynchronous Engineering Service Channel
carried across the satellite link as an overhead added to the main data
channel. The ESC channel can be internally linked to the remote M&C port,
allowing any modem to be monitored or controlled from the distant end of the
satellite link. In addition, external equipment (such as radio transceivers) if
coupled into the remote M&C port may also be accessed remotely over the
satellite link.
Higher specified P300 modems additionally feature many
advanced functions including variable code rate Reed-Solomon, the ultimate in
T1/E1 Drop/Insert functionality, separate ESC & Aux channels with
independent electrical interface selection, a built in Bit Error Rate Tester
(BERT) which can run continuously through the ESC or Aux channels logging
results in the traffic log, plus a Closed Net Plus ESC (`minimum overhead`)
mode in which the overhead varies from
To provide as simple as possible software upgrade facility,
the embedded monitor & control software can be changed without opening the
product. Unlike other equipment which holds the embedded M&C software in
EPROMs (requiring replacement EPROMs to be shipped, changed & returned),
the P300 Modem M&C software is downloaded in to FLASH memory via a rear
panel serial port from a PC. A process which requires no tools and is completed
in 30 minutes. For operators requiring the latest features or upgrades, the
most recent release of the internal M&C software is available on our Web
site (http://www.paradisedata.com) for free download.
