This fixes a regression in 2.2.0 where certain configurations will fail patloop test or have repeated HDLC aborts because the VPMADT032 is modifying the clear channel or d channel data streams. This restores the behavior to how it was in dahdi-linux 2.1.0.4.

This essentially moves the function of dahdi_dummy into the core of DAHDI. It ensures that if DAHDI is loaded, it will always be able to provide timing, regardless of whether there are board drivers loaded, or if the board drivers are properly calling dahdi_receive. If there is a master span loaded which is calling dahdi_receive, then the behavior will be like it is normally. This functionality is off by default, uncomment CONFIG_DAHDI_CORE_TIMER in include/dahdi/config_dahdi.h in order to enable it. ........ git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/branches/2.2@6864 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2009-04-29echocan: Improve interface for echo cancelers.Shaun Ruffell
Echo cancelers are now able to report if they are able to automatically disable their NLP portions in the presence of tones in the audio stream. Also, the interface is changed to allow user space to just disable the NLP portion of the echo canceler. These changes improve fax and modem handling in DAHDI. This commit merges in the changes on http://svn.digium.com/svn/dahdi/linux/team/kpfleming/echocan_work Patch by: kpfleming Also contains improvements to CED tone detection.

2009-02-02Array-style echo canceller updates first appeared in Zaptel, because HPEC ↵Kevin P. Fleming
only supports that mode. However, when the function for doing array-style updates was written, the argument names were reversed. In Zaptel this did no harm, because HPEC was the only module that used array-style updates. When DAHDI was created, non-array-style updates were removed, and the existing modules were converted to using array-style updates. Unfortunately the new code was written based on the argument names, which were incorrect. This caused all the echo cancellers to be broken (except HPEC, although we did not know that at the time), and it was corrected by reversing the order of the arguments passed when the array-style update function was called (leading to a confusing mismatch). This fixed all the non-HPEC modules, but left HPEC broken, which was just discovered. This commit corrects all these problems, so that the argument names and the data passed actually make sense, and all the modules work properly. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@5936 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2008-08-06A significant change to the DAHDI transcoder interface and the wctc4xxpShaun Ruffell
driver which breaks backwards compatibility. Basically, I've replaced the memory mapped interface with a read/write interface that allows codec_dahdi to communicate with the hardware transcoder the exact size of the packet to be transcoded. This eliminates issues with remote devices that send G729.B CNG packets even though asterisk does not support them. From a user standpoint: - The transcoder drivers are much more robust in light of system / external conditions. From a developer standpoint: - DAHDI_TRANSCODE_OP is no longer supported, instead use DAHDI_TC_ALLOCATE, DAHDI_TC_GETINFO, and write/read. - Memory and stack usage is reduced (stack usage could still be reduced some more by continuing the process of getting rid of the users of wctc4xxp_send_cmd and wctc4xxp_create_cmd). - If more than one card is in the system channels will be allocated in a round-robin fashion from all available cards, reducing contention for the supervisor channel. - There is no longer a tc400b workqueue created that will not show up in the process list. - Commands and their responses are now explicitly matched up which elimated certain errors caused by unsolicited messages from the transcoder confusing the driver. - There is now an option to export a network interface for capturing traffic to/from the hardware transcoder. - codec_test has been removed from the dadhi/linux package. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@4717 a0bf4364-ded3-4de4-8d8a-66a801d63aff
