Network Time Synchronization (NTS) System

Asystem that maintains time-of-day synchronization for all devices in the Nortel Multiservice Switch network. NTS resides in the control processor software and synchronizes the local real-time clock interface module from an IP-reachable network management system time server connection. NTS also accepts local operator commands for setting the local time.

When NTS for Nortel Multiservice Switch, NTS for Nortel Multiservice Data Manager, and NTS for DPN-100 are used together, they provide one network time-of-day reference used by all

DPN-100 modules, Multiservice Data Manager workstations, and Multiservice Switch nodes in the network.

network-to-network interface (NNI)

Frame relay service can be provided through a standard interface between two frame relay networks of different manufacture. The interface is called the network-to-network interface. For more information, see NN10600-900 Nortel Multiservice Switch 7400/15000/20000 Frame Relay Technology Fundamentals.
