Line Isolation
Unit 12C
High voltage isolation for analogue lines in a compact sealed unit
The Line Isolating Unit 12C provides high voltage isolation on analogue telephone lines with broadband delivered to “Hot” sites such as high voltage electricity sub-stations that are subject to a rise of earth potential.
The LIU12C has an integral VDSL splitter which allows direct connection to the LIU3C for PSTN services. The isolator may also be used on ADSL, ADSL 2+, SDSL, SHDSL, SHDSL. bis, VDSL & VDSL2 service lines. Services are selected via internal links.
