ABSTRACT:
The outside distribution plant of the invention consists of a remote narrowband terminal such as a digital loop carrier and a remote broadband terminal such as broadband distribution element or the like that receive narrowband and broadband telecommunications signals, respectively, from a switching system or other network element. The signals are delivered to a variety of different types of line cards where each of the different types of line cards provide a different type of telecommunications service as is known in the prior art. Connection lines emanating from selected ones of the broadband line cards are connected to the inputs of a remotely controlled crossbar array where the inputs of the array can be selectively connected to the outputs of the crossbar array. The outputs of the crossbar array are connected to distribution lines that terminate at one of a plurality of diplex filters. By properly configuring the crossbar array, the broadband line cards can be connected to any of the diplex filters such that any customer line has access to any available broadband line card. A plurality of narrowband line cards are connected to the diplex filters such that a combined broadband and narrowband signal can be delivered to selected ones of the customer lines. In this manner the network resources can be efficiently distributed among the customer lines. Likewise, connection lines emanating from other narrowband line cards are connected to the inputs of a second remotely controlled crossbar array to allow a second narrowband line to be connected to selected ones of the customers.
