Table 14-10. ASYNC Overhead Parameters
AUPC functions are available through the use of the optional Async
overhead channel or the optional Reed-Solomon cards. The operator can
select local AUPC to be enabled or disabled.
The operator can select from 0 to -40 dBm in 0.5 dBm steps, for the
nominal, minimum, and maximum transmit power levels. Changes in the
power level shall not interrupt the carrier.
The operator can select the E b /N 0 target setpoint from 3.2 to 16.0 dB in
0.1 dBm steps.
The operator can select the maximum tracking rate from 0.5 to 6.0
dBm/minute in 0.5 dBm/minute steps.
The operator can select transmit power level to Maximum, Nominal, or
Hold for both local and remote carrier loss.
Note: Local carrier loss has priority over remote carrier loss.
The operator can select remote AUPC to be enabled or disabled. The
operator can also select a remote transmit 2047 test pattern and a remote
baseband loopback to be enabled or disabled. The operator can monitor
the remote AUPC 2047 bit error rate.
