Abstract

Apparatus and methods relating to bonded interconnection of local communication networks are disclosed. Bonded communication links, including multiple constituent links that have been bonded together, are terminated to enable communications over the bonded links using bandwidth available on the constituent links. A cross-connect function determines whether received communication traffic is to be forwarded to one or more of a local communication network and the terminated bonded links. The received communication traffic is forwarded in accordance with the determination. The local communication networks may include ring networks, linear networks, or both. The bonded links and links between nodes in a local communication network are bonded DSL (Digital Subscriber Line) links in some embodiments. Bonding of DSL links in this manner can be used, for instance, to extend the reach of DSL service without sacrificing bandwidth.
