Enter the three parameters and validate with the OK button.
Note : ATPC with 1+1 Hot Standby Systems
In 1+1 HSB systems, ATPC parameters are defined at antenna access. As in most cases, the 1+1
HSB coupler is not symmetric, the transmit power at antenna access depends on the transmitter
which is in traffic.
ATPC settings are defined at antenna access for the main ODU (ATPC transmit power at antenna
access = Main ODU Transmit Power – Coupler Losses.
3.2.4.8 - Configuring the Interleave
If the network requires a low transfer time, it should be necessary to inhibit interleaver features.
Transfer time depend on the data rate. Typical transfer time figures with or without interleaver are
given in the table below :
Capacity Interleaver on Interleaver off
2xE1 5 ms 1.6 ms
4xE1 2.5 ms 0.8 ms
8xE1 1.25 ms 0.4 ms
16xE1 0.62 ms 0.2 ms
To configure the interleaver use the menu Tools / Interleaver. The following dialog box appears :
ON : The interleaver is enabled
OFF : The interleaver is disabled
Click on the ON/OFF button to configure the interleaver and validate by clicking on the OK button.
Note : if there is no problem with the transfer time, keep the interleaver enabled. This will improve
error correction especially if burst errors occur.
