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 [[Extension::109]] is assigned to a handset. Feel free to add solutions and specs here, and idea's or progress logs on the {{discuss}}. == intro == DECT, one of the common wireless standards you will find in telephony, is [https://dedected.org/ fairly] [http://dect.osmocom.org/ exploited], and can be a fun playground for phreaks and other geeks :) KingOfDos, member of [http://dukesofhackers.eu/ 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 [https://dedected.org/trac/wiki/COM-ON-AIR 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|buying hardware together]] section contain the following chips: * PCM16C010: Configurable PC Card Interface Chip, front left * '''[[Media:SC14422_datasheet.pdf|SC14421CVF]]''': Complete Baseband Processor for DECT Base Stations, front right (also, see [[Media:SC14425_datasheet.pdf|SC14425]] and [[Media:SC14428 datasheet.pdf|SC14428]]) * '''[[Media:LMX3161 datasheet.pdf|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. <gallery> File:Coa inside.jpg File:Coa_back.jpg </gallery> [[User:Prodigity|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: <pre> root@persephone:/home/xopr# grep pcmcia /var/log/messages <...> Apr 21 20:53:30 persephone kernel: [ 7.140936] yenta_cardbus 0000:03:00.0: pcmcia: parent PCI bridge I/O window: 0x4000 - 0x4fff Apr 21 20:53:30 persephone kernel: [ 7.140943] pcmcia_socket pcmcia_socket0: cs: IO port probe 0x4000-0x4fff: clean.

I [http://wiki.freeswitch.org/wiki/FreeSwitch_Modules 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. [[Category:Telephony]]
