Figure 5: Front and Rear Views of the ISDN Simulator
Ports / Interfaces
There are both S/T and U interfaces for each port of the simulator, but only one interface type can be active for
each port. Again, remember that a TE1 or TA device plugs into the S/T interface jack, while a NT device plugs
into the U interface jack.
