TranSwitch Demonstrates Wireless Backhaul Solutions and New High-Performance xDSL Controller at NXTcomm 2007

NXTcomm 2007

CHICAGO--(BUSINESS WIRE)--TranSwitch® Corporation (NASDAQ: TXCC), a leading provider of carrier-class semiconductor solutions for the converging voice, data and video network, will demonstrate its latest solutions for wireless backhaul and broadband access at NXTcomm 2007 in Booth # 6407, McCormick Place, June 19-21.

The wireless backhaul demonstrations will feature two TranSwitch products: PacketTrunk™-4 Plus for 2G/2.5G wireless backhaul over packet infrastructure, and EtherMap®-PDH for 3G wireless backhaul over existing T1/E1 infrastructure.

The PacketTrunk-4 Plus emulates T1/E1 or T3/E3 circuits over a packet network using any of the defined industry standard protocols (TDMoIP, SAToP or CES). It also provides extremely accurate clock distribution over a packet infrastructure.

EtherMap-PDH transports native Ethernet traffic over all the PDH protocols (E1/T1/J1, wideband DS3 or channelized DS3) that are widely deployed in today’s infrastructure. TranSwitch will demonstrate this functionality using Telrad’s TAG-10c CPE unit and TAG-10a AMC module for ATCA systems, both of which are based on the TranSwitch EtherMap-PDH device.

A third demonstration will feature Diplomat™-IP, TranSwitch’s newest high-performance xDSL line card controller capable of simultaneously supporting a mix of ADSL2/2+, VDSL and VDSL2 traffic. Diplomat-IP’s high throughput and TR-101 compliance makes it ideally suited for bandwidth intensive triple-play services.

TranSwitch telecommunications experts will deliver educational presentations in the company’s booth during the three days of the event starting at 11:00 a.m. on June 19:

* Last-Mile Access Technologies for Mobile Backhaul
* Migration to Ethernet-Based DSL Aggregation Networks
* Network Architectures for Delivering Metro Ethernet Services
* Circuit Emulation and Sync-over-Packet Choices for Enterprises and Providers
