France Telecom brings layer 2 and layer 1 down on BRI lines when the line is idle. When layer 1 goes down Asterisk cannot make outgoing calls and the HA8 and HB8 cards also get IRQ misses. The inability to make outgoing calls is because the line is in red alarm and Asterisk will not make calls over a line it considers unavailable. The IRQ misses for the HA8 and HB8 card are because the hardware is switching clock sources from the line which just brought layer 1 down to internal timing. There is a DAHDI option for the B410P card to not tell Asterisk that layer 1 went down so Asterisk will allow outgoing calls: "modprobe wcb4xxp teignored=1". There is a similar DAHDI option for the HA8 and HB8 cards: "modprobe wctdm24xxp bri_teignored=1". Unfortunately that will not clear up the IRQ misses when the telco brings layer 1 down. * Add layer 2 persistence option to customize the layer 2 behavior on BRI PTMP lines. The new option has three settings: 1) Use libpri default layer 2 setting. 2) Keep layer 2 up. Bring layer 2 back up when the peer brings it down. 3) Leave layer 2 down when the peer brings it down. Layer 2 will be brought up as needed for outgoing calls.

libpri: An implementation of Primary Rate ISDN Written by Mark Spencer <markster@digium.com> What is libpri? =============== libpri is a C implementation of the Primary Rate ISDN specification. It was based on the Bellcore specification SR-NWT-002343 for National ISDN. As of May 12, 2001, it has been tested work with NI-2, Nortel DMS-100, and Lucent 5E Custom protocols on switches from Nortel and Lucent. What is the license for libpri? =============================== libpri is distributed under the terms of the GNU General Public License, which permit its use and linking with other GPL'd software only. The GNU GPL is included in the file LICENSE in this directory. As a special exception, libpri may also be linked to the OpenH323 library, so long as the entirity of the derivative work (as defined within the GPL) is licensed either under the MPL of the OpenH323 license or the GPL of libpri. If you wish to use libpri in an application for which the GPL is not appropriate (e.g. a proprietary embedded system), licenses for libpri under more flexible terms can be readily obtained through Digium, Inc. at reasonable cost. How do I report bugs or contribute? =================================== For now, contact the author directly. In the future if there is sufficient interest, we will setup a mailing list. Does anything use this library so far? ====================================== Yes, the Asterisk Open Source PBX does. http://www.asterisk.org Also, the Zapata library has hooks for it. http://www.zapatatelephony.org Special thanks ============== Special thanks to Jim Dixon <jim@lambdatel.com> for his help in testing and fixing the implementation.
