This option allows the output G.703 DS-3 signal level to be increased if the
receiving end is placed some distance away (> 68 metres (225 Feet)). The
receiving end could be the TT6120 as in a Test Application or a G.703
Repeater. If selected to High, the Transmitter preshapes the output signal
amplitude.
Reed-Solomon Option
NOTE…
Only available if the MUX rate has been set to 204 Byte Packet Mode.
Forward Error Correction requires 16 Bytes for Reed-Solomon encoding.
Interleaver Option
NOTE…
Only available if Reed-Solomon is set to On.
The Reed-Solomon encoding pattern is arranged so that the information is
read in Row format and then read out to the Framing stage in Column
format.
Randomizer Option
NOTE…
Only available if Reed-Solomon is set to On.
The Reed-Solomon encoded pattern is Randomised according to the DVB-C
standard.
Clock Mode Option
NOTE…
This option should be set to Slave and is the ONLY setting to be used in this application.
When sending MPEG-2 packets directly into Telecommunications framing,
the output must be sent at a constant fixed rate. This can be performed
using two methods.
Master: Generate an MPEG-2 transport rate that fits exactly into the
Telecommunications rate.
Slave: Insert 'stuff' packets to fill up the Output Rate.
Direction Option
This option cannot be altered and should always be displayed as Tx. This
indicates that the G.703 card portion of the G.703 Interface Module is set
to Tx mode.
