CAUTION
If NET Keep-Alive is FAIS (framed AIS) or AIS, then setting this optio
to
NO causes out-of-service condition during excessive BER; it starts
when the OOF (Out Of Frame) is detected and lasting as long as the
condition persists, with an additional 0 to 255 seconds (depending
on the user-selected alarm delay
time). The default is 10 seconds.
Each CSU has an input buffer in each direction that allows it to tolerate
jitter in the incoming signal from the equipment (EQP) and network. The
40-bit buffer provides maximum jitter tolerance and a maximum signal
throughput delay time of 42 microseconds (65 bits) in each direction.
Set the equipment-side jitter buffer to YES (default value) for most
applications.
To reduce the equipment-side throughput delay time to 17 microseconds
(27 bits), select
NO . If NO is selected, a buffer length of 16 bits is used.
However, this setting also reduces the CSU’s input jitter tolerance.
When enabled (set to YES ), this option allows the CSU to pass all BPVs,
including both non-B8ZS and B8ZS-coded ones, from the equipment
(EQP) to the network.
When transparency is disabled ( NO ), the CSU removes non-B8ZS BPVs
from the equipment input and passes only the B8ZS-coded BPVs to the
network. However, remember that B8ZS is passed only if the CSU is
configured for B8ZS NET side encoding and the equipment is set for
B8ZS decoding.
The default is NO .
Set this option for the amount of line build-out (LBO) needed to provide a
DS1 signal of the proper amplitude to the first line repeater on the
network. Choose one of the following:
0 dB The first repeater is 2000 to 3000 feet from the CSU. This
is the default setting.
