HIGH SPEED DSL ACCESS
The 1424 SHDSL.bis EAD targets business customers with a need for high speed symmetrical bandwidth in various DSL networks and at various local loop distances. It includes a SHDSL.bis interface up to 4 copper pairs. This provides line rates up to 22Mbps on short distances and up to 10Mbps on operator standard loop lengths. The various pair bonding techniques make it suitable for any type of DSL infrastructure. The symmetrical line rates of SHDSL perfectly match the traffic profiles of business users. Providing Ethernet in the First Mile over SHDSL.bis, the 1424 is interoperable with the major IP DSLAM vendors.

METRO ETHERNET SERVICES
The 1424 relies on the robust TDRE software, the OneAccess Bridging and Routing Engine offering advanced layer 2 and layer 3 services. Ethernet functionalities include filtering and policing based on layer 2 and layer 3 characteristics, priority policing and shaping and advanced VLAN features. These features fully meet the requirements of operators deploying Metro Ethernet services. With a bidirectional routing or bridging performance of 250Kpps, the 1424 SHDSL.bis EAD easily handles all layer 2 and 3 services even at 22Mbps.

SMOOTH MIGRATION FROM ATM TO EFM NETWORKS
Operators gradually migrate from ATM based access networks to Ethernet based access networks. The 1424 supports both network types. This means that a 1424 can be installed in an existing ATM network. When the network migrates to Ethernet, the same 1424 can be re-used in the Ethernet network without on-site intervention. The unique feature of combining ATM and EFM access in the same device leverages a smooth migration of the access network.

HIGH NETWORK AVAILABILITY
A dedicated Ethernet interface is available as a backup when the DSL network is not available. Traffic is automatically routed to the available network. Alternatively this interface can be used for a DMZ zone (De-Militarised Zone) on the customer’s network.

ACCELERATED DEPLOYMENT AND SERVICE PROVISIONING
As all TDRE routers, the OneAccess 1424 SHDSL.bis EAD is manageable through a variety of maintenance and management tools. These include:

• A free graphical user interface for local or remote maintenance
• A customisable Web-configuration utility
• A CLI to facilitate scripting
• Easy integration into Network element management platforms such as TMA or HP OpenView.
