Broadframe Releases In-Line DSL Protocol Analyzer For VoATM Development

Broadframe Corporation announced an in-line DSL protocol analyzer for developing and testing voice over ATM (VoATM) applications. The Broadframe DSLscope is a powerful, compact unit that enables decoding and debugging of data protocols over a live DSL connection.

"The DSLscope provides the ability to evaluate and decode the data running inside the DSL connection," said Mike Trujillo, Broadframe President. "The DSLscope is a valuable tool to engineers involved with DSL because they no longer have to guess what's happening between the DSLAM and the Customer Premise Equipment (CPE). DSL Developers, testers, and installers will be more productive by focusing quickly on solving problem rather than speculating on the cause."

Broadframe's DSLscope a DSL protocol analyzer that operates in-line on the copper loop. DSLscope records all traffic between the DSLAM and CPE transparently, records raw ATM cells (AAL0, AAL2, etc.), decodes AAL2 BLES CAS, and reconstructs the AAL5 packets. TCP/IP, PPP, and all of the major DSL encapsulation schemes (RFC 1483/2684 LLC/SNAP, RFC 2364 PPPoA, RFC 2316 PPPoE) are supported. Other decodes are being developed.

ADSL ITU 992.X Annex A is supported; Annex B is under development. Other technologies such as G.shdsl and VDSL are planned.

The DSLscope product line is the second family from Broadframe and focuses on in-line evaluation and analysis. Broadframe's original product family, Liberator, provides network simulation to DSL developers.

DSLscope is very useful in troubleshooting DSL line connections. Visibility into the data stream will speed up installation. Interoperability and conformance testing applications will find DSLscope useful to ensure encapsulation schemes are equivalent across platforms. DSL equipment developers can use DSLscope to record data traffic and decode, evaluate, and analyze data protocols on the DSL wire.
