Hi guys,
In GSM 12.21 there is a mistype. In par. 8.8.1 State Changed Event
Report, it says Length of Availability Status is >= 2, but actually it's
=4. Cause if you look at part. 9.4.7, you have 1 octet
for Attr. Id.
(T), 2 octets of Length (L) and Avail. State (V), which could contain
one or more octets.
I found this fault when I was analyzing pcap with Wireshark and gsm
spec. 12.21.
