External Receiver Circuitry
2.4.4
To compensate for the extra delay introduced into the received signal by a filter, the sampling
of the receive signal can be delayed by programming bits TEM and PFS in the ADF1 register
as shown in table 3. Note that setting TEM to "1" and PFS to "0" has the effect of completely
disabling layer-1 functions, for test purposes (see section 2.6).

This delay compensation might be necessary in order to comply with the "total phase deviation
input to output" requirement of CCITT recommendation I.430 which specifies a phase
deviation in the range of – 7% to + 15% of a bit period.
