Receive Jitter Attenuator Enable
This bit permits the user to enable or disable the Jitter Attenuator in
the Receive Path within the XRT86VL32 device.
0 = Disables the Jitter Attenuator to operate in the Receive Path
within the Receive E1 LIU Block.
1 = Enables the Jitter Attenuator to operate in the Receive Path
within the Receive E1 LIU Block.

Transmit Jitter Attenuator Enable
This bit permits the user to enable or disable the Jitter Attenuator in
the Transmit Path within the XRT86VL32 device.
0 = Disables the Jitter Attenuator to operate in the Transmit Path
within the Transmit E1 LIU Block.
1 = Enables the Jitter Attenuator to operate in the Transmit Path
within the Transmit E1 LIU Block.

Jitter Attenuator Bandwidth Select:
In E1 mode, this bit is used to select the Jitter Attenuator Bandwidth
as well as the FIFO size.
1 = Selects a 1.5Hz Bandwidth for the Jitter Attenuator. The FIFO
length will be automatically set to 64 bits.
0 = Setting this bit to “0” will select 10Hz Bandwidth for the Jitter
Attenuator. The FIFOS (bit D0 of this register) will be used to select
the FIFO size.
The table below presents the Jitter Attenuator and FIFO settings
corresponding to the combinations of this JABW and FIFOS bits in
both T1 and E1 mode.
