Abstract
A clock for locally distributing a synchronized signal derived from a remotely transmitted signal. The clock normally operates in the slave mode, phase locked to the remotely transmitted signal, when that signal is deemed available. If it is not available the clock switches to a master mode in which it independently generates the necessary signal.
