U2B1Q Interface Module
The U2B1Q interface module provides two connectors for line connection,
which are designated as follows:
H“LT A” or “LT M ” (old: “to LT”)
H“NT/LT B” or “NT/LT N” (old: “to NT(LT)”)
Modes of Operation. To monitor lines with the U2B1Q interface module,
proceed as follows:
1. Deactivate the line concerned and separate it.
2. Connect the network to the socket labelled “LT A”/“LT M” and
connect the NT to the socket labelled “NT/LT B”/“NT/LT N”. The
interface module responds in the line like a U-repeater.
