Shunts

A shunt on the WAN port allows the same connector to be configured for an ITU-T V.35 electrical

interface signaling or EIA-232C/D signaling. The ITU-T V.35 signaling levels are generally more

reliable for high speed data and/or longer cable distances. The EIA-232C/D signaling is intended for

data rates of 19.2 Kbps or less and cable lengths of 50 feet or less. For higher speeds and/or longer

distances, the V.35 is generally preferred.

The shunt positions are toward the back of the printed circuit board (See Figure 1-4).

Figure 1-4. Shunt Positions

The RouteFinder has a shunt for the RS-232 and the V.35 links. The RS-232 and V.35 shunt positions

are identified. To change the position of the shunt, refer to the V.35 “Changing Shunt Position”

procedure.
