The P1 and P2 Jumpers are defaulted to RJ-48S, which are the set of pins nearest the
bottom of the service card. With the jumper in this position the signals are routed to the
RJ-48S connector(s) on the face of the card. To route the signals to the 25-pin Telco
connector at the rear of the unit, move the jumpers to the backplane position, which is
the set of pins toward the top of the service card.
P1 applies to connectors 1 and 2 (connector 2 only with the 4 port card).
P2 applies to connectors 3 and 4 (for the four port card only).
