   You might consider using a standard modem and telephone line and
connecting to the NIST ACTS service. This service will provide an
of a few milliseconds and a stablility of about 1 millisecond with a
30-second call to the NIST server in Colorado. It requires no outside
and no special hardware.
     The details of the service are on the NIST web page:
tf.nist.gov. Look
for ACTS.
