7-1 Cable trunk and branch lines

On the illustration of the cable wiring below, a bold line means a trunk and the thin lines branched

from the trunk with a “T” shape are called branch lines.

The length of branch lines branched from the trunk should be within 400 mm.

Total cable length should be within 1 km.

7-2 Relaying of trunk cables

To relay trunk cables, use the straight joint (ME-JJ-01).

Relaying of trunk cables should be limited to indispensable cases only. Inadvertent relaying of

trunk cables may cause a communication fault such as a weakened signal level due to contact

resistance in the junction connector (straight).
