Jitter Attenuator Select. If one,
the attenuator may be connected to
either the transmit or receive sides
of the PCM 30 interface depend on
bit 6 - JAT/JAR. If zero, the jitter
attenuator function is disabled.
Attenuator.
attenuator will function on the
transmit data. If zero, the jitter
attenuator will function on the
receive data.
Jitter Attenuator FIFO Centre.
When this bit is toggled the read
pointer of the jitter attenuator shall
be centered. During centering the
jitter in the JA outputs is increased
by 0.0625 U.I
Jitter Attenuator FIFO Depth
Control Bits. These bits determine
the depth of the jitter attenuator
FIFO as shown below:
Jitter Attenuator Clear bit. If one,
the Jitter Attenuator, its FIFO and
status
registers will identify the FIFO as
being empty. However, the actual
bit values of the data in the JA
FIFO will not be reset.

equalizer is turned off from the auto
mode. If zero, the receive equalizer
is turned on and will compensate for
loop length automatically.
Receive Equalization Mid-range.
If one and REDBL is one, the one-
stage equalization is enabled, which
provides approximately 6 dB of
gain. If zero, REDBL or REMAX will
control the receive equalization.
one, REDBL is one and REMID is
zero, the two-stage equalization is
enabled,
approximately 12 dB of gain. If zero,
REDBL or REMID will control the
receive equalization.
