Troubleshooting ISDN-PRI endpoints (wideband)

The following flow chart describes a layered approach for troubleshooting problems with an ISDN-PRI
endpoint. Because problems at lower layers affect upper layers, layers are investigated from low to high.
In this procedure, the:

•

DS1 facility is layer 1

•

TN2312AP IPSI circuit pack’s Packet Interface circuit is layer 2 (

S8100

: TN765 Processor

Interface is layer 2)

•

PRI endpoint’s ports are layer 3 (

S8100

: ISDN trunks are layer 3)
