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 * HFC-E1 Datasheet ([http://www.colognechip.com/hfc-e1.pdf]) * The HFC-E1 Evaluation Board of ChipCologne ([http://www.colognechip.com]) * Beronet BN1E1 Card (http://www.beronet.com/downloads/whitepapers/BNXE1.pdf) * Junghanns.NET SingleE1 card (http://www.junghanns.net/en/singleE1_produkt.html)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)
