Troubleshooting—Common Symptoms
The most common problems when installing T1 or PRI services:
1.
The service provider misconfigures your T1/PRI service or terminates
your service improperly.
2.
T1 is installed but not turned on because there is no termination device
for a period of time.
3.
T1 is turned on but channel is not in service.
AltiAdmin provides basic troubleshooting information in the T1 Span
Configuration window, described in "Triton T1 Configuration - Triton T1/
PRI/E1 Dialog Box" on page 6-42.
Several diagnostic tools are available that can help troubleshoot these
situations, such as a T1 watcher ("T-Berd") or a multimeter. For more
