Main Office Configuration for Survivable Remote Gateway 50 Configuration Guide
• NRS Database — stores the central dialing plan in XML format for the
H.323 Gatekeeper. The H.323 Gatekeeper accesses this common
endpoint and gateway database.
• Network Connect Server (NCS) — used only for Media Gateway
1000B (MG 1000B), SRG, Geographic Redundancy and Virtual Office
solutions. The NCS allows the Line TPS (LTPS) to query the NRS using
the UNIStim protocol.
• NRS Manager web interface — the NRS provides its own web
interface to configure the H.323 Gatekeeper and the NCS.
The NRS application provides routing services to H.323 devices. The H.323
Gatekeeper can be configured to support H.323 routing services. The H.323
Gatekeeper can reside on the same Signaling Server.
Each system in an IP Peer network must register to the NRS. The NRS
software identifies the IP addresses of systems based on the network-wide
numbering plan. NRS registration eliminates the need for manual
configuration of IP addresses and numbering plan information at every site.
When configuring the NRS it is necessary to enable the NCS. Ensure that the
check box “Network Connection Server enabled” is checked in the NRS
configuration window of CS 1000 Element Manager.
For information about configuring the NRS, refer to IP Peer Networking:
Installation and Configuration (553-3001-213).
