AnimportanttoolforunderstandingfundamentalcompatibilityproblemsistheZephyr

Xstream’sintegratedISDNanalyzer.Thisallowsexaminationofthetransactionsbetweenthe

TelcolineandtheXstream,sothatajudgmentcanbemadeastowhethertheproblemlies

withintheXstreamorwithth

eprogrammingoftheTelcoswitch.Thiscanbeusefulwhenthe

lineitselftestsgood,butsomethingisincorrectlyconfiguredattheTelco.

TheusualcauseofinabilitytodialproblemsisaTelcoproblem,suchmis‐programming.
