The IEPC is an integrated power controller especially designed for feeding two- and four wire

transmission lines. The IEPC is fully compatible to the CCITT recommendations on power feed at

the “S”-interface. So the IEPC can be used in PABX/Central Office and in intelligent NT´s.

The IEPC supplies power up to four transmission lines. Each line is individually powered and

controlled via microprocessor interface. An interrupt output signals any malfunction to the

microprocessor.

The high voltage CMOS technology (60 V) ensures a wide field of applications:

– two- and four wire transmission lines

– point-to-point configurations

– point-to-multipoint configurations etc.
