We have DECT in the space using a Fritz!Box, but still want to use a Com-on-air card for DECT provisioning. Currently, extension 109 is assigned to a handset.

Feel free to add solutions and specs here, and idea's or progress logs on the discussion page.

intro

DECT, one of the common wireless standards you will find in telephony, is fairly exploited, and can be a fun playground for phreaks and other geeks :)

KingOfDos, member of Dukes of Hackers (space in Den Bosch) pointed me something interesting, which I thought wasn't available anymore. He had set up a 'buying together' thing for it.

There is a card with a SC14421 chipset which allows you to set up a DECT base station, which could be used in our own Telephone_System, or with the correct driver, also usable for (permissory) sniffing of calls.

COM-ON-AIR card

The cards ordered in the buying hardware together section contain the following chips:

  • PCM16C010: Configurable PC Card Interface Chip, front left
  • SC14421CVF: Complete Baseband Processor for DECT Base Stations, front right (also, see SC14425 and SC14428)
  • LMX3161: Single Chip Radio Transceiver, inside the HF shielded module on the front
  • E622A: Integrated Quad Half-Bridge, inside the HF shielded module on the front
  • 2205AF: 3.6V 0.5W RF Power Amplifier IC for DECT, inside the HF shielded module on the front
  • VHCT04A: Hex inverter, on the back
  • 93LC86: 8K/16K 2.5V Microwire Serial EEPROM, on the back

Click on the chip to view the data sheet.

The bold printed chips do the magic.

Note that there is support for the SC1442x and U2785 Com-on-air cards.

Prodigity notes: Because of the lack of backward compatibility, some laptop manufacturers have chosen to release models incorporating both CardBus (PCMCIA, PC Card) and ExpressCard slots. These include certain models of Acer Aspire, Toshiba Satellite, Dell Latitude and Precision, MSI S42x and Lenovo ThinkPad Z60m, R52, T60 and R61.

PCI to PCMCIA type III adapter

Tested if the DECT card would fit and work, and this is the result:

  • dedected source just doesn't seem to compile on newer kernels.

creating a freeswitch endpoint module

I (Xopr) find this the 'innovative' part of the project ;)

Just as there is Asterisk module source code for the DECT stack, there should be something similar for FreeSWITCH. I haven't seen any, so I'm planning to set it up myself, after I can compile the basics successfully. There is a lot to do here, so the more people committing, the merrier.
