6.5.7 C/I Equivalence Table
The C/I codes are identical for all
functional modes. The C/I codes for
the extended mode (GCI) are more
logically organized and kept identical
over the different modes.
IDENTICAL commands and indications
which use the same abbreviation are
marked as a single C/I in UPPER
CASE. IDENTICAL C/I have
sometimes the same abbreviation
except for the letters "u" and "d"
(uplink an downlink). Those are
marked as single C/I in Mixed Case.
All commands and indications which
have different abbreviation but same
meaning and on the same position
have the equal sign "=".

The basic command in lower case, the
extended command in upper case.
All commands and indication which
are different but on the same position
are marked with the star sign "*", C/I
for basic mode at the left.
Unused positions are marked "-".
Some positions are NOT USED BY
ONE DEVICE ONLY; then they are
marked with both "-" and "*".
Some of the mixed command and indi-
cation codes (i.e. used * unused) are
merged in the MTC-20172 SIC. This is
marked with "&". The command used
in one device is allowed in the unused
position of the other device. Some
mixed indication (i.e. used * unused)
can also be merged: The lsl indication
is deleted, the ei indication will also
appear in the NT extended mode.
