Interphase Announces New Design-Friendly Interworking Solution

Introducing the iSPAN 3650 AdvancedMC (AMC) Quad OC-3c/STM-1 ATM-IP Interworking
Card and Application
PLANO, Texas--(Business Wire)--
Interphase (NASDAQ: INPH), a leader in embedded networking and communications
solutions, introduces the iSPAN 3650 AdvancedMC (AMC) Quad OC-3c/STM-1 ATM-IP
Interworking Card. The iSPAN 3650 delivers unprecedented performance for
bridging cell-based and circuit-based networks and provides outstanding design
value. Based on the powerful Wintegra WinPath2 on-board network processor, the
iSPAN 3650 hardware can support:

* 64,000 ATM PVCs (Permanent Virtual Circuits)
* 1 M/s AAL2 CPS packets
* 50,000 Active CIDs supported for AAL2 PVCs

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.
