RAD Puts GigE Over ATM

TEL-AVIV -- RAD Data Communications has announced the release of the ACE-201, an attractively priced network termination unit (NTU) that allows service providers to deliver new high speed Gigabit Ethernet services over their existing ATM infrastructure.

As a customer premises-located equipment (CPE), the ACE-201 also defines a demarcation point between the provider’s network and the customer premises. This provides the dual benefits of end-to-end traffic and network management control for the operator with no exposure to the ATM network for the user. Alternatively, the ACE-201 can serve as a traffic concentrator to enable enterprises to take advantage of public ATM networks for their Ethernet-based internetworking.

“Many leading carriers are heavily invested in ATM technology,” says Robert Bell, Product Line Manager at RAD Data Communications. “ACE-201 lets them leverage their existing infrastructure to offer popular new high-capacity Ethernet services and generate new revenues without making any further capital investments. With this NTU, there is no need for changes in the edge or the core networks, so deployment time is short, and costs and risks are minimal,” continues Bell.

Fast Connection and Complete Interoperability

The ACE-201 ATM uplink has a standard STM-1/OC-3c interface supporting service speeds of up to 155 Mbps and is available with single mode 1310 nm, short or long haul fiber interface. This allows for fast deployment by connection to an existing ATM switch STM-1/OC-3c port. The single Gigabit Ethernet user port comes with a choice of copper or fiber interface. The Ethernet frame size can be up to 1594 bytes to allow special formats, including ISL and stacked VLANs.

The ACE‑201 is compatible with other RAD ACE family products and can interoperate with any third-party ATM device or network. It also supports OAM functionality per ITU-T I.610 to help reduce operational costs by providing end-to-end traffic manageability and fault localisation.
