Hi Harald,

You once posted a pcap of a "Network Listen" process of the ip.access 
nanoBTS, I think.
If I anlyze the traffic, I can't find any messages leading to "Network 
Listen" activities.
According to the nanobts product spec. "Network Listen" is an ip.access 
specific message, so when looking at 0xfe (ipaccess) I only see the 
Ping/Pong messages.

In GSM 12.21 I couldn't find something about scanning or listening for 
other ARFCNs. But it's possible I haven't read the spec well or didn't 
understand completely.

Any idea's?
