Using the SynWatchUtility B

Overview

The SynWatch utility is a protocol analyzer that enables you to watch frames exchanged between the communications controller and the ISDN network. This powerful utility helps you track communication establishment on the ISDN D channel and data traffic on ISDN B channels. Each ISDN channel has a stand-alone configuration that can be selected or deselected.

SynWatch provides diagnostics for ISDN connection failures It also helps you detect PPP connection failures (for example, PPP negotiation using Remote Access Service).

SynWatch interprets exchanged frames according to several protocols. (Remote Access Service uses the PPP protocol.) It displays these frames according to the appropriate protocol.
