Hi

This is a follow-up to http://bugs.debian.org/491310 . I have recieved a
number of similar reports. Upon further inspection, it seems that all of
them use zaphfc as a Zaptel driver.

While the Debian package in question greatly differs from the main 
Asterisk one (bristuff), the relevant property is supported in main 
Asterisk 1.6 as well: bri ptmp CPE support in chan_dahdi.

BRI ptmp telephony providers tend to keep the line down. And it seems
that most Zaptel card drivers don't provide timing to Zaptel when the
layer 1 is down.

So at least until tose drivers are fixed, if layer 1 does not happen to
be up at the time Asterisk is started, Asterisk will fail to start.
