The GT-VBC can be used as an extension adaptor as well (2
units per trunk line).
To do so, set the setting switch (SW2) to "EXP".
Use the unit as an extension adaptor in expanded systems.
Even if two units are used as extension adaptors (SW2:
EXP), the wiring distance to the farthest residential station
from the GT-VBC (SW2: STD) or GT-VBX is limited to 300 m.
