There are two methods available to place an outgoing ISDN-PRI test call in
G3iV1.1-286 and G3iV2-386.
In the first method, the test call connection is established over the TDM Bus of
the transmit and receive sides of the ISDN-PRI trunk to a data channel. This
method is selected when no Maintenance/Test circuit pack resides in the system.
In the second method, the test call connection is estab lished over the TDM Bus
of the transmit and receive sides of the ISDN-PRI trunk to a d igital trunk testing
port on the Maintenance/Test circuit pack. The Maintenance/Test Digital Port
generates a pseudo bit stream. A pictorial description of the outgoing ISDN-PRI
test call connectivity is contained in the following figure.
