Overture 1400 Edge Platform Gets an Upgrade
By Calvin Azuri
Overture recently released its 3-port DS3 interface module and software enhancements for the Overture 1400 platform, the company’s award-winning gigabit Carrier Ethernet edge platform. The company is a specialist and preferred carrier Ethernet edge and aggregation partner for a large number of service providers and network operators across the globe.
In a release, Vijay Raman, vice president of product management and marketing, Overture Networks (News - Alert) said, “Carriers are looking for ways to better serve the needs of all customers, including those who require reliable high bandwidth services but can’t connect directly to the optical network due to physical or geographical barriers, or other gating factors. With the Overture 1400 Release 12.1 and the 3-port DS3 interface module, service providers can quickly and easily meet customer demand for premium business services. It’s another powerful solution that allows us to turn the difficult into the doable.”
The new enhancements were introduced as part of release 12.1 and came with new software upgrades add MLPPP bonding to the existing T1/E1 interface module, along with capabilities for rapid service activation, dynamic re-marking of service classes and synthetic loss measurements.
The debut of the new module will enable both carriers and network operators to leverage readily available DS3 circuits to offer performance-assured Ethernet at speeds exceeding 100 Mbps to sites lacking dedicated fiber access. The 3-port DS3 linecard for the Overture 1400 supports Virtual Concatenation (VCAT) bonding using Link Capacity Adjustment Scheme (LCAS) and Generic Framing Procedure (GFP).
The 3xDS3 module is supported by Overture’s Release 12.1, which gives it a number of additional performance enhancements and upgrades such as zero touch provisioning – which allows the Overture 1400 to be installed at the customer site and automatically configured remotely with no local on-site intervention; dynamic p-bit remarking, which allows traffic that exceeds the committed information rate (excess information rate or “EIR”) to be marked with a priority bit valued for special handling by upstream networks; Y.1731 synthetic frame loss (ETH-SLM), which provides the accurate one-way measurements of frame loss by injecting specialized test traffic alongside live user traffic and MLPPP support on the existing 8-port T1/E1 interface module, which provides an alternative industry standard encapsulation and bonding technique for use with edge routers and aggregation switches.
Previously, the module only supported GFP encapsulation with PDH-VCAT bonding.
