Private Integrated Services Network (PISN) - Inter-exchange signalling protocol - PINX clock synchronization (SYNC-SIG)

2nd edition, September 1997

This Standard specifies the signalling protocol for the support of clock synchronization (SYNC-SIG) between Private Integrated Services Network Exchanges (PINXs) connected together within a Private Integrated Services Network (PISN).

This protocol supports the synchronization of a PISN using the different sources of clocks available to each PINX. The protocol is based on the method of synchronization described in annex F of the International Standard ISO/IEC 11573.

This Standard is applicable to PINXs which can be interconnected to form a PISN.
