Abstract

A loop carrier system includes a home local area network having plural telephone modules and a hub coupled to in-home telephone wiring. The telephone modules and the hub communicate voice signals over the in-home wiring in a dedicated frequency band above baseband POTS. The hub converts between voice signals and voice packets and is connected to a network access device for transferring the voice packets from the home local area network to a telecommunications network which routes the voice packets to a gateway. The gateway converts between the voice packets and a circuit format compatible with a local digital voice switch. A network element includes a Common Object Request Broker Architecture (CORBA)-based server, CORBA-based managed objects accessible by the CORBA-based server and a CORBA-based applications programming interface (API). The CORBA-based API is coupled to an external operations support system which can manage the plural CORBA-based managed objects directly.

Claims

1. A telecommunications network comprising:

one or more management systems for managing network elements; and

a managed network element comprising;

a CORBA-based server;

plural CORBA-based managed objects accessible by the CORBA-based server; and

a CORBA-based applications programming interface (API) coupled to the CORBA-based server, the CORBA-based API coupled to at least one of the management systems for managing CORBA-based managed objects therefrom.

2. The telecommunications network of claim 1 wherein the managed network element further comprises a management protocol agent as a CORBA-based client of the CORBA-based server, the management protocol agent coupled to an element management system for managing CORBA-based managed objects therefrom.

3. The telecommunications network of claim 2 wherein the management protocol agent is an SNMP agent.

4. The telecommunications network of claim 1 wherein the managed network element further comprises an embedded operations channel agent as a CORBA-based client of the CORBA-based server and wherein the plural CORBA-based managed objects includes GR-303 managed objects, the embedded operations channel agent coupled to an external local digital switch for managing the GR-303 managed objects therefrom.
