P300 Series Modem Installation and Operating Handbook
Description of Feature
A Tx path: without this the modem can be Rx only
B Rx path: without this the modem can be Tx only
P Variable rate: Variable data rate if enabled (see `R`), fixed if not (See `Q`)
S 70MHz IF interface: IF frequencies in the range 50 - 90MHz
(provides 50-180MHz if feature `T` also)
U 100Hz IF synth steps: 2.5KHz if not enabled
V Misc ASIC functions: Terrestrial CRC support & BER monitoring
Viterbi FEC (to IESS 308/309), rate ½, ¾, &
Sequential FEC (to IESS 312) , rate ½, ¾ &
L Reed-Solomon outer FEC (to IESS 308/310), with n, k, t = 126, 112, 7
(switches to 225, 205, 10 or 219, 201, 9 with 4/8 deep interleaving as required for IDR &
TCM/IDR if options are available)
T 140MHz IF interface: IF frequencies in the range 100 - 180 MHz
(provides 50-180MHz if feature S also available)
R If data rate is Variable by feature `P`, then data rate range is 4.8kbps to 5.0Mbps if this feature
enabled otherwise limited to rates between Low_Rate and High_Rate (see bottom of table).
No effect if feature `P` disables variable rate
G Variable rate ESC channel for Closed Net plus ESC operation
High rate IBS/SMS ESC (with IBS/SMS feature)
Async ESC access to IDR 8k sync ESC channel (with IDR option).
E IBS/SMS framing (to IESS 309) with low rate INTELSAT ESC (to IESS 403).
C Normal T1/E1 linear order Drop/Insert, excludes `Odd values of N` such as N=7, 9 etc (see
feature D)
IDR operation (to IESS 308): Two audio ESC channels, Sync 8kbps ESC, Four form `C`
backward alarms.
H Aux: IBS variable rate synchronous Aux channel, IDR 32/64kbps in place of one/both audio
ADPCM ESC channels
J P1348 emulation: Emulation of P1348 / P1448 cards popular in SNG applications. Includes
generation of 64kbps carrier from 2 x 32k ADPCM audio (using IDR Audio ESC ports), or
128kbps from 2 x Audio + 64kbps data.
K PRBS tester: Internal BERT (can run through Main, ESC and Aux channels in any o/h modes)
O 8PSK with rate Trellis Code Modulation (TCM, to IESS 310).
b
D Arbitrary Timeslot re-ordering on Tx & Rx paths. Timeslot ID maintenance for the `Odd values of
N` giving N=1 to 31 with IBS/SMS or Closed Net plus ESC operation. E1 CAS & T1 RBS
signalling support. Rx Partial Insert (for multi-destinational working)
I Arbitrary `n` & `k` when using Reed-Solomon, Custom and Minimum Overhead framing modes,
Custom allocation of IBS o/h between Async ESC & Sync Aux ports.
Q Dual rate: If data rate is fixed by feature `P`, then fixed at Low_Rate unless this feature enabled
when choice of Low_Rate or High_Rate is available (see below). No effect if feature `P`
enables Variable rate
Turbo Codec inc rates ½, ¾,
f
Later model P300 only (previously letter `W` was spare = active).
X Spare (active)
Y Spare (inactive)
Z Auto Uplink Power Control (requires Async ESC feature also to function)

offset frequency (in addition to normal AGC output). Constellation monitor port
