Somebody who knows Zaptel better could tell you whether this is a bad idea,
but my first thought was:
take out the config for that span from zaptel.conf,
then run ztcfg.

Although my memory is that will kill any calls on any zaptel device?

A solution that has worked for us to physically switch circuits into
Digium cards is:

The AFS-16 has a serial device that you can then control with your
favorite serial controller software.
