Profile

The HFC-E1 is an E1 controller chipset for PCI bus, produced by CologneChip.

There are a number of cards using this chipset, among others

Evaluation Board

CologneChip offers a HFC-E1 Evaluation Board, which is used by our project.
Other HFC-E1 cards should theoretically work, too - although this has not
been tested. The card has to support 120Ohms NT mode.

Hardware configuration

We set the Jumper and termination configuration as follows:
  • 120 Ohms Termination
    • 1: off
    • 2: on
  • NT Mode Config A (Pin1/2: Rx, Pin 4/5: Tx)
    • All JP6 and JP1 jumpers between pins 1 and 2 (left)
