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
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.
Variable data rate in 1 bps steps with fast acquisition even
at low data rates
Viterbi FEC (to IESS 308/309), rate 1/2, 3/4 & 7/8 in
BPSK, QPSK and OQPSK. 100Hz IF resolution
Can accommodate Viterbi & Sequential FEC simultaneously
Deferred alarm at user set service limits (individual Eb/No, BER & Buffer slip thresholds)
Frequency locked clock loops (ie not phase locked) immune to
clock hits caused by equipment such as routers
Software includes two User Variables` to accommodate custom
user requirements (such as special alarm handling), allowing special user
requested features to be added whilst still keeping common software
