80% of that of the first algorithm. The T1 jitter tolerance with ALGSEL set to 1
and to 0 is shown in the following illustration.

The input jitter tolerance for E1 interfaces complies with ITU-T Recommendation
G.823. The tolerance is measured with a 215-1 sequence. The E1 jitter tolerance
is with ALGSEL set to 1 and to 0 is shown in the following illustrations.
