The RG and the Telecommunications Management Network

adapter) to the requesting adapter. The requesting adapter can now independently pass small bursts or cells of information to the allocated adapter. The requesting adapter may, for example, have received from the residence PC LAN a request to initiate an Internet Protocol session. The packet representing this request is fragmented by the LAN adapter into multiple cells, which are then transferred via the bus to the access network adapter. The register address allocated by the system manager will correspond on the access network adapter to a data transport service. Obviously, there may be multiple requests for this kind of service, and their requests are managed separately, using the stream identifier allocated by the requesting adapters. The access network adapter assembles the cells into the format required for transmission over the access network and transmits them inbound.

As can be seen from this example, for the RG to operate reliably, the protocol for exchange of data among the various adapters must be very tightly defined, and each adapter should be tested for compliance.

It is proposed that the RG NIUs be compliant with the Telecommunications Management Network (TMN) interface specifications. Use of internationally agreed upon object definitions allows immediate introduction of new devices from multiple vendors into the network without impact to existing service provider operational support systems. It is anticipated that a single network will ultimately support millions of RGs, precluding the exclusive use of polled management schemes such as the Simple Network Management Protocol (SNMP). It
