When combined with the Interworking application from Interphase, the iSPAN 3650 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 excellent 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.

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 this gateway AMC an ideal solution for wireless network elements that connect to the 3GPP Iu interface, such as 3G RNCs, SGSNs, Femtocell/HNB gateways, and LTE Serving gateways.

The iSPAN 3650 will be on display at the MicroTCA Conference held November 3 in Munich, Germany.
