An RJ-45 crossover cable might be required when connecting the
PRI network interface module to a PBX or other third-party network
access device.
If you have an in-service PRI line, connect the PRI interface module
to an external 12 VDC power source before plugging the PRI line
into the ViewStation FX or VS4000.
