TEST METHOD
The following test method will allow you to verify the proper operation of the ISDN PRI in the
PBX without a physical connection to the network.

as the user side (normal operation) and the second PRT configured as the network side. The two
PRTs should be connected together.

You should be able to place calls from Station A via ISDN to Station B.
Figure 7 shows the connection of two 24PRTs for test purposes.
