7.3. Configuring the Feature 
The Large Enterprise Gatekeeper (LEGK) is a feature for IP trunking
address resolution for data transfer in IP networks. The configuration
of this feature is broken down into the following steps which are to
be performed in consecutive sequence:
- Configuration: Database flexama memory - Section 3.4, “Configuring the FLEXAMA Memory in the Database”, on page 545
- Configuration: HG 3500 - Section 3.5, “Configuring a HG 3500 on the LAN Segment”, on page 549
- Configuration: HG 3500 directory numbers - Section 3.6, “Configuring the HG 3500 Directory Number”, on page 567
- Configuration: LCR digit analysis - Section 3.7, “Configuring IP Trunking in the LCR”, on page 569
- Configuration: Subscriber, trunk and tie trunk connections in the local switch - Section 3.8, “Configuring Circuits and Terminals”, on page 574
The LEGK feature must be taken into consideration when configuring IP
trunking. If IP trunking is already available, it must be re-generated.
The following sections contain configuration examples and detailed
explanations of all requisite AMOs and AMO parameters. A distinction
is made between
 |
configuration with OpenScape 4000 Assistant/Manager
(Configuration Manager) or
|
 |
AMO-based configuration.

The Large Enterprise Gatekeeper can be implemented in all OpenScape
4000 system configurations. An LEGK can either be implemented in all
nodes or in a single node in an OpenScape 4000 network.
