JASEL1_n
Jitter Attenuator select bit 1: The JASEL1 and JASEL0 bits
are used to disable or place the jitter attenuator of each chan-
nel independently in the transmit or receive path.

Jitter Attenuator select bit 0: See description of bit D3 for the
function of this bit.

JABW_n
Jitter Attenuator Bandwidth Select: In E1 mode, set this bit
to “1” to select a 1.5Hz Bandwidth for the Jitter Attenuator. The
FIFO length will be automatically set to 64 bits. Set this bit to
“0” to select 10Hz Bandwidth for the Jitter Attenuator in E1
mode. In T1 mode the Jitter Attenuator Bandwidth is perma-
nently set to 3Hz, and the state of this bit has no effect on the
Bandwidth.
