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 established over the TDM Bus
of the transmit and receive sides of the ISDN-PRI trunk to a digital 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.
