Centralized Attendant Service or Call Accounting System
A unit of call traffic. Call traffic for a facility is scanned every 100 seconds. If the
facility is busy, it is assumed to have been busy for the entire scan interval. There are
3600 seconds per hour. The Roman numeral for 100 is the capital letter C. The
abbreviation for call seconds is CS. Therefore, 100 call seconds is abbreviated CCS.
If a facility is busy for an entire hour, then it is said to have been busy for 36 CCS.

application. Capability groups denote association types. For example, Call Control is
a type of association that allows certain functions (the ones in the capability group) to
be performed over this type of association. Also referred to as administration groups
or application service elements (ASEs).
Call-Associated Temporary Signaling Connection
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.
