BUsing the SynWatch
Utility
Overview
The SynWatch utility is a protocol analyzer that enables you to
watch frames exchanged between the adapter and the ISDN
network. This powerful utility helps you track communication
establishment on the ISDN D channel, as well as data traffic on
ISDN B channels. Each ISDN channel has a stand-alone
configuration, and can be selected or deselected.
SynWatch provides diagnostics for ISDN connection failures.
It 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.
This appendix explains how to do various SynWatch tasks,
such as:
• Access online help
• Start the utility
• Use mouse buttons to select SynWatch functions
• Watch ISDN channels
• Watch ISDN Layer 1 alarms
• Stop and freeze the display
• Change the watch mode
• Edit ISDN channel settings
• Save and edit frames.
