Ericssons microwave radio solution, MINI-LINK BAS, will now supports both Asynchronous Transfer Mode (ATM) and traditional Time-Division Multiplexed (TDM) transmission. By supporting both ATM and TDM configurations in the same equipment, the solution can handle traffic both in current generation (such as GSM), and third-generation (3G) mobile networks.
MINI LINK BAS now enables operators to offer at least three levels of service to suit different traffic and customer needs. This means Ethernet services can be delivered with the option to customise connections to offer throughput and Quality of Service (QoS) while still being able to cap the maximum throughput for each individual connection.
MINI-LINK BAS does this by introducing a new service category that combines Unspecified Bit Rate (UBR) and Minimum Desired Cell Rate (MDCR) techniques. This UBR+MDCR intermediate service category – between Constant Bit Rate (CBR) (for real-time voice, data and video traffic) and plain UBR (for pure best-effort services) – provides a minimum bandwidth, with extra bandwidth provided.
MINI-LINK BAS now also includes an Ethernet Gateway that provides native Ethernet backhaul and enables operators to deploy the system in an all-Ethernet environment.
Other improvements in the latest version of MINI-LINK BAS include an upgraded Central Processor (CP) that is both faster and smaller, and enables twice the number of radios to be managed by one CP. Enhancements to the management system included mirrored discs that improve reliability and resilience, together with an enhanced user interface that makes it faster and easier to view, manage and deploy network facilities.
