38.2 Concepts
Access delay The actual delay as measured by the RBS
of the received signal from an MS, relative
to the expected signal from a reference
MS. The reference MS is assumed to be:
positioned at zero distance from the RBS,
operating under static channel conditions
and having zero timing advance.
Ignored Optional element in /GSM:08.58/. The
element is ignored if received by the RBS.
Main DCCH Main signalling channel (SDCCH or
FACCH).
The following special terms, regarding A-bis information elements
stated as optional by /GSM:08.58/, are used in this document:
Optional Optional element in /GSM:08.58/. The
RBS supports optional use of the element.
If the element is present, it is used.
However, the element is not required, i.e.
if the element is not present the RBS takes
no further action.
Rejected Optional element in /GSM:08.58/. The
message containing this element is
rejected by the RBS. The sender of the
message is notified using an appropriate
error handling procedure.
