Assuming that all of your 3 secondaries have a good Internet
connectivity, I suggest you to establish a so-called "an unpublished
primary" scheme. The necessary steps are:
1. Remove your master server from the NS records in your zone file;
2. Choose one of your slave servers and put its host name in the SOA
record replacing the master server name;
3. Run the zone update process and wait for the new zone version to be
propagated to all of the slaves;
4. Update the list of the name servers in the parent zone by editing it
at your domain registrar control panel (you need to remove the old master).
After the updates described above you will be still in full control over
your zone and your ISDN connection will be freed from the incoming DNS
