Using the Analyzer
To Monitor a Channel (VPI/VCI)
2 Using the Analyzer
Channel Monitor collects and displays statistics after a channel is selected
using Link Monitor, or after a channel is specified on the Monitor Channel
window. When the statistics are available, Channel Monitor shows them
for the past 300 seconds. The analyzer starts collecting statistics as soon
as you select a channel, even if Channel Monitor is not displayed.
Note For AAL-3/4 SAR, ATM statistics for the entire channel are displayed; however, AAL
statistics are displayed only for the selected MID.
For AAL-3/4 channels with more than one MID, Channel Monitor AAL measurements are
available only after you select a specific MID. You can select a MID in the Channel Monitor
window only if you select to decode the channel manually as AAL-3/4 in the Set Up Channel
window.
