Although the TA information element contains the TA value in an
octet (byte), GSM 04.08, v7.6.1, clause 10.5.2.40 clearly shows
TA as a 6-bit field (containing "Timing advance value").

The extra two bits of the octet are labelled "spare".  This is a
different wording from the case where some zero bits are included
in a field, but unused - in such cases they are described as
"reserved".
