Hello all, Just thought I would give everyone an update on my progress with the Ericsson RBS. I got a T1 card, a Digium TE122P (http://www.digium.com/en/products/digital/te122.php). This card support E1/T1/J1. The 2401 I have only supports T1, otherwise I would have gotten a HFC based chipset that OpenBSC supports. The TE122P uses the DAHDI drivers, which used to be Zaptel. In reading through the list archives, I found a couple tidbits about Zaptel. The first was back in February from Harald: http://lists.gnumonks.org/pipermail/openbsc/2009-February/000023.html. I didn't see any updates after that. Were there updates made to make the integration with other drivers easier? The next I found was in March from Klaus-Peter Junghann: http://lists.gnumonks.org/pipermail/openbsc/2009-March/000064.html. It looks like he actually got the Zaptel driver to work. I'm not sure how much of Zaptel has changed when the driver set was renamed to DAHDI. I did not see a post from Mr. Junghann with the zaptel input module he spoke of. I'm not sure what the interest level is with getting OpenBSC to integrate with Ericsson RBS's? Like I previously mentioned, I am not much of a coder, so I can't help much in that department. That being said, I am willing to provide remote access to all the resources I have here (Debian Linux 5.0 Server, RBS 2401, Windows LMT). I can also provide access to a spec an (which would be accessed via software on the Windows LMT) if needed down the road. I am going to look into a STA to test on a couple ARFCN's in the GSM1900 band, and I am more than willing to help with handset debugging at that stage. I have quite a few different handsets lying around! Thanks much, Caleb
