been busy for 36 CCS. See also Erlang.

cause value
A value is returned in response to requests or in event reports when a denial or unexpected
condition occurs. ASAI cause values fall into two coding standards: Coding Standard 0 includes
any cause values that are part of AT&T and CCITT ISDN specifications; Coding standard 3
includes any other ASAI cause values. This document uses a notation for cause value where the
coding standard for the cause is given first, then a slash, then the cause value. Example: CS0/100
is coding standard 0, cause value 100.
