Claims to enhance performance for bridging cell-based and circuit-based networks
Interphase has unveiled iSPAN 3650 AdvancedMC(AMC) Quad OC-3c/STM-1 ATM-IP Interworking Card, which it claims to deliver enhanced performance for bridging cell-based and circuit-based networks.
Based on Wintegra WinPath2on-board network processor, the hardware of the Interworking Card can support, 64,000 ATM PVCs (Permanent Virtual Circuits),
1 M/s AAL2 CPS packets, and 50,000 Active CIDs supported for AAL2 PVCs.
When combined with the Interworking application, the Interworking Card becomes an integrated gateway on an AMC, especially designed to support OC-3c/STM-1 interfaces in ATCA and MicroTCA (µTCA)-based systems. This configuration provides an enhanced value proposition for equipment manufacturers seeking to expand capability of existing products and for network service providers seeking to reduce costs by foregoing expensive external ATM gateways, the company claims.
According to Interphase, for both AAL2 and AAL5 data, the ATM-IP Interworking application enables the transport over IP for voice, data, and control traffic to/from other processing units via the gigabit ethernet (GE) backplane. Other available protocol stacks include UDP/IP over GE and GTP-U tunneling. The software, fully embedded on the card, includes the protocol layers, the management and configuration plane, the line/equipment protection, and the data Interworking application.
The GTP-U tunneling capability makes the gateway AMC suitable for wireless network elements that connect to the 3GPP Iu interface, such as 3G RNCs, SGSNs, Femtocell/HNB gateways, and LTE serving gateways, Interface said.
