The IEPC is fully patible to the CCITT remendations 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. PEB 2025 Programmable output current and thermal shut down guards the IEPC against overloads. The IEPC offers a special transient permitted overload state. Momentary overloads within a specified range e.g. by connecting a TE to a powered line, however, will not activate the currentlimit-circuits of the power controller. If overload is detected, the line driver will turn off according to a time and current dependent turn off characteristic. The IEPC offers an automatic restart-mode. In this case the IEPC tries to...
