NOTE:
The maximum number of channels available in a PC based system is 15. However
when using 15 interpretations, it is recommended to use two CCU's, one for contribution
and one for interpretation. The maximum number of channels available in a system where
one CCU is used for both contribution and interpretation is 11.

10.10.1 Interconnecting Interpreter desks

The interpreter desk, includes the same interconnection facilities as the delegate and chairman units
(FIG 10-23). Interpreter desks can be connected in series using the loop-through cabling method, or
to a Tap-off Unit LBB 4115/00. When using the Tap-off unit LBB 4115/00, two interpreter desks - one
to each tap-off connector only - can be connected to the trunk-line cabling,

10.10.2 Interconnection between booths

FIG 10-24 shows a typical system using either Trunk-splitter LBB 4114/00 or Tap-off unit LBB 4115/00.
Using the examples, interpreter desks can be arranged in booths at specific locations where needed.
Using the Trunk-splitter method a multiple of units in series are connected to a single Trunk-splitter.
Using the Tap-off unit LBB 4115/00, only ONE desks can be connected to a single tap-off, allowing in
total only TWO interpreter desks to be connected. In the event of a unit failure, other desks
connected to the same line can be affected. Using the Tap-off unit, only one booth is affected,
however using the Trunk-splitter all units connected to a single line can be affected.
