Summary:                    when digium analog hardware is loaded before digium
digital hardware, ztcfg fails due to CAS signalling
Description: 
bug 0007860 does not differentiate E1 from T1, and the patch includes a
test for
"(ZT_CONFIG_D4|ZT_CONFIG_ESF|ZT_CONFIG_B8ZS|ZT_CONFIG_CCS)"

ZT_CONFIG_D4 && ZT_CONFIG_ESF are T1 Framings
ZT_CONFIG_B8ZS is T1 coding

when an analog card is loaded first then a digital card, ztfg fails with
"CAS signalling on span 2 conflicts with Clear Channel on channel 16.",
when the cards are loaded in reverse order (digital then analog, and the
proper config changes are made) ztcfg works fine.

Cards: 
Wildcard TE12xP Card 0
WCTDM/0 "Wildcard TDM400P REV I Board 1
(in order when working)

A workaround is to just remove the test. Maybe that is the best option for
1.2 . . Recall that this is but a sanity check.

This patch has a potential to cause false alarms because the test for
ZT_SIG_CLEAR alone may not be good enough.
