accessed remotely. Provides Clock, Data, & Sync (Octet timing) lines.
Synchronous access to 8 kbps IDR ESC. With the Async ESC feature
(standard on P300-IBS and above) async ESC access to the 8kbps
IDR ESC is provided, giving up to a 9600 Baud async channel
IBS & Closed Net plus ESC facilities as before installation of IDR
option, but now on ESC port on IDR card not shared ESC/Aux port of
base unit.
RS232 or RS422 (software selected). Provides Clock and Data lines.
Provides 32 or 64 kbps access in place of one or both Audio ESC
channels.
INTELSAT low rate ESC mode as previously but now via Aux port on
IDR card not shared ESC/Aux port of base unit. IDR option also adds
sync IBS mode, configurable to use between 1/32nd and 21/32nd of
the IBS overhead providing a full sync Aux port at between 0.2% and
4.3% of main data rate.
Aux port provides satellite timing information for P1500 Slave
Frequency Standard when not configured for Aux data access.
The IDR Option includes the facility to emulate the more common
modes of our popular P1348 / P1448 voice / data mux cards which are
used extensively in SNG applications. It uses the IDR audio ESC ports
for the audio interfaces and can generate a 64 kbps carrier consisting
solely of two 32kbps ADPCM encoded audio channels, or a 128 kbps
carrier comprising the two audio channels plus 64 kbps data from the
main interface. This is compatible with a P400 Series modem fitted
with P1448 card or a P230 Modem with a P1348 card, alternatively
Drop/Insert can be used at the distant end to place the two 32kbps
ADPCM audio channels in one timeslot and the 64 kbps data in
another.
PRBS tester may operate through either main traffic, ESC data, or
AUX data channels (main traffic channel not available in Closed Net, ie
no overhead mode). Use of ESC & AUX data channels allow
continuous real traffic BER performance monitoring on links with
overhead.
