Network Time Synchronization (NTS) System
A system 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
