Table 3: N2 Bus rules
Category Rules/maximums allowed
1,500 m (5,000 ft) twisted pair cable without a repeater
4,500 m (15,000 ft) twisted pair cable from NAE35/45 and the farthest N2
device (three segments of 1,500 m [5,000 ft] each, separated by repeaters)
Line Length and
Type
2,000 m (6,600 ft) between two fiber modems
Cable Solid or stranded 1.0 mm (18 AWG) 3-wire is recommended. Solid or stranded
0.5 mm (24 AWG) or larger 3-wire or 4-wire (two twisted-pairs) is acceptable.
Note: The + and - bus leads should be a twisted pair. On applications
using 4-wire (two twisted-pairs) cable, isolate and insulate unused
conductor.
Terminations Preferred Termination Configuration: Two N2 devices with EOL switches in
the ON position, one at each end of each N2 Bus segment
Minimally Required Termination Configuration: At least one N2 device with
an EOL switch in the ON position somewhere on each N2 Bus segment

1 For the bus topology, the maximum length stub cable is 3 m (10 ft), and the stub lengths must be calculated into the
overall segment length.
