T1/PRI straight-through cable: RJ-48C to DB-15
Before installing the RJ-48C to DB-15 straight-through cable, verify that the WAN transmits
the signal received by the APX 1000 on pins 3 and 11 and receives the signal transmitted by
the APX 1000 on pins 1 and 9. Table C-5 and Figure C-3 show the pinouts.
