Complete ATM-IP Interworking Solution on a Card

The iSPAN 3650 AdvancedMC (AMC) addresses a range of applications requiring interworking solutions that bridge ATM and IP networks, and it takes advantage of open standards to offer a smooth interworking solution in a significantly less expensive format.

Single Card Solution Significantly Reduces Operating Costs

The iSPAN 3650 can be easily integrated into standard systems so the switching/routing function that typically consumes an entire system can be accessible on a single card. The 3650 enables OEMs to add tremendous value to their products with its integrated ATM-IP interworking function on a single AMC, reducing capital and operating expenses associated with reduced space, cooling and power supply costs.

High Performance ATM-IP interworking

For bridging cell-based and circuit-based networks, the iSPAN 3650 delivers unprecedented performance in IP traffic interworking between ATM AAL2/AAL5 and Ethernet with full line rate speeds. Available with a robust ATM/Ethernet protocol suite for traffic management, QoS, aggregation, encapsulation, bridging, routing, and interworking. When combined with the Interphase Interworking application, the iSPAN 3650 becomes an integrated gateway, specifically designed to support OC-3/STM-1 interfaces in ATCA and MicroTCA (µTCA)-based systems. For both AAL2 and AAL5 data, its ATM-IP interworking functionality enables the transport over IP of voice, data and control traffic to/from other processing units via the Gigabit Ethernet backplane. With its GTP-U tunneling capability, the iSPAN 3650 is an ideal solution for wireless Network Elements that connect to the 3GPP Iu interface, such as 3G RNCs, SGSNs, Femtocell gateways and LTE Serving gateways.
