MAY 22, 2008 � Transmode (search for Transmode) has launched its Customer Premises Ethernet Demarcation Unit (CPE-EDU) intended for business Ethernet and mobile backhaul services applications.

The CPE-EDU is designed to offer service providers, mobile operators, and cable MSOs demarcation for demanding business services and wireless backhaul applications. Offering "all common Ethernet interfaces," the CPE-EDU can act as a wire-speed media converter while supporting in-service active and passive performance testing, Ethernet service creation, and SLA validation, according to Transmode.

The compact, standalone CPE-EDU can be placed either on the desk-top, wall-mounted, or mounted in a standard rack.

The new offering closely follows the launch in December 2007 of Transmode's larger EDU, the Edge-EDU. The Edge-EDU is a blade that is inserted in any of Transmode's TM-Series chassis, where it can be collocated with other optical transport units.

The CPE-EDU features two ports, one facing the customer and one facing the network. All throughput and SLA parameters can be managed via in-band management, enabling complete remote management of the CPE-EDU.

"These two EDUs are the first of a series of launches of Layer 2-compatible products in Transmode's TM-Series platform," said Magnus �berg, CTO. "The great benefit is the tight integration of these products in the optical transport platform. Instead of having separate boxes from different vendors, our customers can now provide same or better services with the same management solution. The operator has the option to choose between a clean Layer 1 solution or a combined Layer 1+Layer 2 simply by inserting the relevant blades in the existing card cages."

Both EDUs support business Ethernet applications where the customer traffic is handled as "Carrier Class Ethernet services" as defined by the Metro Ethernet Forum, where different service levels can be applied per port or per VLAN within a port. Different services within the same Ethernet connection can thus be given different levels of priority and guaranteed bandwidth. Performance monitoring is also provided where parameters such as latency, jitter, and lost packets can be used to establish and validate different types of SLAs.
