Processor Sub-System and Software

channels for data and telephony services. The RG may also provide a bridging function among the adapters on the residence side, connecting, for example, a home automation network to a PC LAN.

The RG system contains a microprocessor and memory that supports the software services required to operate the basic function of the device. The system processor and its resources should not be employed for end-user applications, since there is no way to guarantee that these applications will be well behaved, and will not reduce the available computational resources below the level required for reliable operation of the gateway. End- user applications can be supported by imbedding processors and memory on the adapters. It may be possible to boot such adapters with software stored permanently on the system disk.

Software

Software functions to be supported by the control microprocessor include:

  • Registration of adapters (hot-plugging);

  • Connection allocation among adapters, including Quality of

Service reservation;

  • System management of the gateway, including communication with the access network service provider's management system. Network management agent and MIB;
