facility. In the diagram above, notice that System B has three 100D modules (and therefore three ports) to provide synchronization. (See the diagram above.)
NOTE:
If a DEFINITY ECS or DEFINITY ProLogix Solutions system is included in the private network and has functional digital PSTN facilities, it should provide the clock synchronization source.

2.If a star configuration is linked by tandem digital facilities and has no in- service digital PSTN facilities connected to any switch, the primary clock in System B provides clock synchronization for the private network. (See the diagram above.)

System Date and Time | 5 |
For more information on system date and time, see System Programming. When a MERLIN LEGEND Communications System switch is in a private network with one or more other MERLIN LEGEND Communications Systems or with one or more DEFINITY ECS or DEFINITY ProLogix Solutions systems, Station Message Detail Recording (SMDR) reports may report outgoing calls using more than one call record, depending upon how SMDR is programmed and how calls are routed. If SMDR is reporting outgoing calls and users are employing private network lines to make these calls, ensure that the system date and time are set accurately on each system that carries these calls. As you examine call reports, you may need to be aware of time zone differences among private networked system locations.
