libss7 link quality troubles

Yeah, I have a script called reasterisk:

#!/bin/bash
export PATH=/bin:/usr/bin:/sbin:/usr/sbin:/usr/local/bin:/usr/local/sbin
asterisk -r -x "stop when convenient"
rmmod wct4xxp
rmmod zaptel
modprobe wct4xxp
ztcfg -v
nice --1 open -c 10 -- asterisk -vc

It takes care of everything.

I got chan_ss7 working ok, but with frequent CRC/frame too short errors.
I'm using a Version 9 TDM405P, I can't ship it back to USA as it's in
production for the other 2 spans.
