Page 9: Introduction
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.

Page 144: Determining Buffer Size
So using the example figures above gives 0.00898 seconds, so 9ms is required to absorb the plesiochronous effects. To this you must add any Doppler requirement (ie 2ms for each satellite hop). P300H P300 Series Modem Installation and Operating Handbook Page 144...
Page 145: Partial Insert And Multidestinational Working
Partial Insert becomes mandatory for multidestinational working when the total receive data at any one destination exceeds the capacity of the PCM bearers. One final note: The P300 Series can provide multidestinational operation at aggregate carrier rates below 1544 kbps using the IBS overhead, but with four backward alarms. So multidestinational working down to 64kbps between nodes become practical (ie you don't have to use the 96kbps IDR overhead on the links to get multidestinational backward alarm facilities).

Drop/Insert is active the Data Rate is 64kbps times the number of timeslots dropped/Inserted. As the P300 Series Modem use PSK (Phase Shift Keying) the Symbol Rate is the rate of phase changes on the I.F. signal. Each phase change represents a new symbol to the demodulator, and depending on the modulation scheme that symbol may convey one (BPSK), two (QPSK), or three (8PSK) bits of information.

This provides a RS422 compatible station clock in addition to the unbalanced 75 station clock BNC connector. See the menu dialogue in section 6.7.4 on page 92 for a full description of this port. P300H P300 Series Modem Installation and Operating Handbook Page 187...
Page 188 STANDARD LEAD A constellation monitor / serial lead is available from Paradise Datacom, part number M1479. This lead provides the required connections to a 25 pin D type for a PC connection (for printing/capturing a log or updating the modems embedded software), and three BNC s for connecting to a scope for the constellation monitor.

In IDR modes this port provides access to the 8kbps IDR ESC channel. This can either by synchronous at 8kbps, or (if the Async ESC feature is available) asynchronous at up to 4800 or 9600 Baud. P300H P300 Series Modem Installation and Operating Handbook Page 189...

Typically this would be used synchronously, but if required it could be used asynchronously & oversampled giving maximum baud rates of approx 9600 Baud (in place of one audio channel) or 19200 Baud (in place of both Audio channels). P300H P300 Series Modem Installation and Operating Handbook Page 190...
Page 191 In IDR modes these are used to access the IDR Audio ESC channels. One or both Audio ESC's may be dropped in favour of 32 or 64kbps access to the channel by the Aux port. P300H P300 Series Modem Installation and Operating Handbook Page 191...
Page 192: Backward Alarms
For multidestinational IBS carriers it is possible to operate the P300 in IBS mode, but use 4 separate backward alarms as per IDR. From the front panel select Service as `Other`, based on `IBS`, and follow the screen prompts. P300H P300 Series Modem Installation and Operating Handbook Page 192...
Page 193: Appendix C: Upgrade Information
Upgrading a P300 Series modem may then involve the entering of a `Feature Code` into the front panel, or the addition of one of more of the optional hardware items listed above in addition to entering of a `Feature Code` into the front panel.
Page 194: Appendix C1: Modem Capabilities & Upgrades
To determine the hardware capability of any P300 Series Modem see Features: Hardware in Appendix C2 which follows immediately. Any feature for which the modem Hardware is already present can be added by a simple `Feature Code` upgrade from the front panel.
Page 195 (Temporary features). The modem will cease to be able to provide these features when the period expires unless a Feature Code issued by Paradise Datacom is entered. If you have no means to get a feature code from Paradise Datacom (eg lack of comms, public holiday etc), use one of the 5-day user activated Feature Test periods to provide cover until you can contact us.
Page 196 Other features are available but may require a hardware upgrade (ie a chip to be plugged in or a PCB to be added) If you contact Paradise Datacom directly we will supply within a few minutes by fax a Feature Code to provide the extra features you require (eg addition of Reed-Solomon etc). This will be a temporary code valid for probably 30 days to enable you to raise and place a purchase order on your supplier.

ASCII characters. Whilst this is not specified for the Paradise / FDC protocol, Paradise Datacom have attempted to achieve this wherever possible. For this reason, only 6 bits of each character of the `Body` are utilised (bits 0 to 5). Bit 6 is fixed at a one for both protocols, and for the Paradise / FDC protocol (where the character has 8 bits, 0-7), bit 7 is fixed at a zero.

P300 when equipped with the Extended D/I feature uses a derivative of the IBS CAS Multiframe (see later section "CAS Multiframe") to provide timeslot ID maintenance for even these remaining values of N. P300H P300 Series Modem Installation and Operating Handbook Page 214...
