V.35
V.35 uses both single ended and differential signals on a 34-pin block connector. To use this standard,
select the V.35 interface type and use the MicroGate V.35 cable (Part # 2534GT, picture shown below).
LL, RL, and RI signals are available on the HD-26 and DB-25 connectors but are not available (NC = no
connect) on the 34-pin block connector when using the V.35 cable.
Maximum data rate is 10Mbps. Cable length and signal loading may reduce the maximum data rate.
