<p>An access node that is deployable at a distance from a cable company headend or a telephone company central office serves residential and business subscribers within a small geographical area. The access node provides interoperability between and across communications links and protocols, thereby providing a modular, configurable access point for both business and residential users that enables the service provider to tailor its services for each user in a cost-effective manner. The access node includes modular interfaces to multiple communications links and protocols on its network side and modular interfaces to multiple communications links and protocols on its user or access side. A switch/router connects the outputs of the two interfaces together and aggregates traffic to the network while simultaneously partitioning traffic to the users to the appropriate connections.</p> |
