What makes sense, as we were using multi trx-configuration. otoh, i vaguely remember that we were using the edge-channels, what would implicate the 165U model. In our test-set up, about two years ago, we used two different models, a dozen with and a dozen without external antenna's. In that configuration we used an official bts, omc and mmc, and had roaming agrements with our national provider. Considering the age, i presumed i have to upgrade them before i can use them with openbsc and my own asterisk, not ? Would be fun to use them at home, and afaicr people in NL and UK are allowed to do this.... Considering ipaccess, at work we were going to do another test. And during a demo, they claimed that our nano's were to old and had to be upgraded to be able to work with *, hence they left a couple of new examples with us at _no_ costs, but they were very reluctent to provide us with new firmware for the couple of dozens nano's we allready have. Odd, not? But all i really would like to do, is play my own gsm-provider at home, and route voice and sms to my asterisk onto my voip/isdn-provider. I'll bring one along for further examination. Perhaps i can tell you more about model / current firmware. Hans
