US Classification:

370217, 370360, 370463, 714 25

Abstract:

A communication system comprising at least one communication unit. Each communication unit includes an interface port, a first-digital-subscriber-line port, a second-digital-subscriber-line port, and a central processing unit. The central processing unit is communicatively coupled to receive information indicative of the operability of the first-digital-subscriber-line port and the second-digital-subscriber-line port. The at least one communication unit is implemented on the physical layer in single-pair mode. The at least one communication unit is configured to switch from sending timeslots in dual-pair mode to sending timeslots in 1+1 protection mode when communication on one of the first-digital-subscriber-line port and the second-digital-subscriber-line port fails.

US Classification:

370498

Abstract:

A communication network comprises a first digital subscriber line (DSL) unit having a plurality of application ports and at least one DSL port; and a second DSL unit having a plurality of application ports and at least one DSL port; wherein the first DSL unit is communicatively coupled to the second DSL unit via a DSL pair coupled to the at least one DSL port in each of the first and second DSL units; and wherein each of the first and second DSL units are configured to receive a signal of a first interface format over one of the plurality of application ports, extract timeslots from the received first interface format signal, transmit the timeslots over the at least one DSL port, and use timeslots received over the at least one DSL port to generate at least one second signal of a dissimilar interface format.

International Classification:

H04J 3/22

US Classification:

370466

Abstract:

A method of using a digital subscriber link unit as a media converter, the method comprising coupling a first signal of a first type to a first port of the digital subscriber link unit, converting the first signal of the first type to a second signal of the second type with the digital subscriber link unit and outputting the second signal of the second type from a second port of the digital subscriber link unit. The first port and the second port are not G. SHDSL ports.
