The customer is a fixed operator that owns copper infrastructure and uses it for last mile connectivity to its enterprise customers.
The operator's network is based on SDH and MPLS cores. A large number of central offices and co-location sites exist where aggregation devices can be accommodated.
RAD supplies a next generation multiservice access node (MSAN) solution, which enables the aggregation and termination of Ethernet and legacy traffic over copper and designates each for transport over either the SDH or the Ethernet/MPLS edge devices.
This is a dedicated solution for enterprise business services.
-
Leased lines replacement and extension over copper infrastructure
-
Separation of different services and transmission to different core networks
-
Future-proof solution supporting Carrier Ethernet OAM and guaranteed SLAs (Megaplex-4100 phase 3.1), as well as customer connectivity over Fast Ethernet
-
Future proof solution for aggregating all TDM traffic onto STM-1/4 lines Price-competitive
The operator was seeking to concentrate and aggregate Ethernet and leased line (E1 and Ethernet or V.35 and Ethernet) services for enterprise customers. The need was for a managed access solution capable of connecting the end user's PBXs, routers and LANs in order to supply voice and data services.
The Megaplex-4100 is used as an aggregation MSAN. It is installed at the carrier's central offices. Copper infrastructure is deployed to the customer premises. ASMI-54C/N modules accommodate the I/O slots of the Megaplex-4100. The ASMi-52 serves as a CPE, allowing the carrier to supply E1 or V.35 as leased lines, as well as Ethernet services, with up to 100Mbps of bandwidth.
The Megaplex-4100 separates the E1 and V.35 leased lines from the Ethernet traffic and designates each traffic type for transport over a separate core network – nxE1/V.35 to the TDM core and a Gigabit Ethernet uplink to the Ethernet/PSN core. In order to overcome long last mile distances, an SHDSL repeater, the S-RPT, with remote power feeding from the PFH-4 is used.
The solution is fully managed using the RADview-EMS Carrier-Class Element Management System, which enables system configuration and troubleshooting. Management of the whole application is needed in order to maintain high quality SLAs, which are required both by the regulating agency and the end users.
