try link (its about chip DS2154 on e100p):
afaik wct1xxp don't send E-bit (bit 2 of "Transmit Control Register 2"
must be set to 1 to set E-bit) so Telco side have no info about CRC
if you wisch i can send you my version of wct1xxp, unfortunately old
CVS - 15-09-2003 and dirty code :-( , working good with Lucent 5ESS on
Telco side. (contact me off-list)
additionaly this patch show some info about errors on E1 line:
VCR,CRC,EBCR and FASCR
and is possible to change input impedance from 120 OHM to 120 OHM with
resistors or 120 OHM with high resistors - just for test purposes.
