P300
Letter Description of Feature
TCM
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`)
70MHz IF interface: IF frequencies in the range 50 - 90MHz
S
(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
N * Viterbi FEC (to IESS 308/309), rate 1/2, 3/4, 7/8 in BPSK, QPSK and OQPSK.
M * Sequential FEC (to IESS 312) , rate 1/2, 3/4, 7/8 in BPSK, QPSK, OQPSK
Reed-Solomon outer FEC (to IESS 308/310), with n, k, t = 126, 112, 7
L (Switches to 225, 205, 10 or 219, 201, 9 with 4/8 deep interleaving as required for IDR &
TCM/IDR if options are available)
140MHz IF interface: IF frequencies in the range 100 - 180 MHz
T
(Provides 50-180MHz if feature S also available)
If data rate is Variable by feature `P`, then data rate range is 4.8kbps to 5.0Mbps if this feature
R enabled otherwise limited to rates between Low_Rate and High_Rate (see bottom of table).
No effect if feature `P` disables variable rate
Variable rate ESC channel for Closed Net plus ESC operation
G 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).
Normal T1/E1 linear order Drop/Insert, excludes `Odd values of N` such as N=7, 9 etc (see
C
feature D)
IDR operation (to IESS 308): Two audio ESC channels Sync 8kbps ESC; Four form `C`
F *
backward alarms.
Aux: IBS variable rate synchronous Aux channel, IDR 32/64kbps in place of one/both audio
H
ADPCM ESC channels
P1348 emulation: Emulation of P1348 / P1448 cards popular in SNG applications. Includes
J 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).
Arbitrary Timeslot re-ordering on Tx & Rx paths. Timeslot ID maintenance for the `Odd values
D 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)
Arbitrary `n` & `k` when using Reed-Solomon, Custom and Minimum Overhead framing modes,
I
Custom allocation of IBS o/h between Async ESC & Sync Aux ports.
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
Q
`P` enables Variable rate
