and I might add...

a. if any analog phones bridged on the pstn line go off-hook then on-hook,
   the tdm card senses it and rings the appropriate dialplan entry.

b. executing 'stop now' and '/etc/rc.d/inti.d/zaptel stop' followed by a start
   more than a couple of times somehow leaves the tdm card unusable. Reboot
   the machine fixes the problem (RH9).

c. disconnecting the analog pstn line from tdm card (and then reconnecting)
   causes the appropriate dialplan entry to ring exactly twice.
