An IP DSLAM (Internet Protocol digital subscriber line access multiplexer) is a multiplexer located primarily in the central office telephone company exchange that provides customer access to DSL services over twisted pair copper cabling. The device typically separates the voice and data components from the subscriber lines and aggregates the data for sending over the packet switched backbone network. An IP DSLAM incorporates packet-switched technology to interface with an Ethernet, IP or MPLS backbone for high capacity traffic aggregation.
In many instances, operators may not have direct access to a packet switched backbone network but must transport the aggregated packet switched traffic over an SDH, SONET or PDH network. By using dedicated converters it is possible to backhaul IP DSLAM over leased SDH/SONET facilities, or alternatively, aggregate traffic from an IP DSLAM over n x E1/T1 data services.
For backhaul of IP DSLAM traffic, RAD offers a Gigabit Ethernet over STM-1/OC-3 Intelligent Converter, which enables simple, efficient and cost-effective bridging of Gigabit Ethernet over STM-1/OC-3 lines. This device comes with an electrical or optical Gigabit Ethernet interface, supporting extension of the traffic and eliminating the cost of maintaining several devices.
RAD’s channelized Ethernet gateway and Ethernet over n x E1/T1 inverse multiplexer can aggregate up to 32 or 42 remote IP DSLAMs, connected over n x E1 or n x T1 lines respectively.
