<p>End point device interacts directly and/or indirectly both with a first node using a first protocol and a second node using a second protocol. In one embodiment, the first node and the second node are access points. The second node does not have first node network address even if it is communicatively coupled to the first node via an alternate upstream path. The first node does not know second node network address. The end point device has the first node network address and the second node network address. The second node sends data destined for the first node to the downstream end point device. The end point device applies necessary coding, formatting and/or encryption to the data before delivering the data to the first node using the first node network address if the first protocol is different from the second protocol. Else the end point device forwards the data to the first node. The end point device in addition acts as a bridge for data from the first node to the second node. Each of the first protocol and the second protocol is circuit switched or packet switched data communication protocol.</p> |
