CCSA Access C-14
C-14 CCSA Access
General Description
This feature enables connection to a CCSA network. CCSA networks provide customers with the use of a
completely private inter-facility dial system. They use individual facilities for dedicated access lines and trunks that
terminate in common control switching equipment and in various types of telephone equipment at customer
locations.
Operating Procedure
To place an outgoing CCSA call
1. Lift the handset; receive dial tone.
2. Dial the CCSA ACCESS code; receive second dial tone.
3. Dial the desired number.
4. Wait for the call to be processed.
To answer an incoming CCSA call
1. The Attendant presses either the CCSA or ANSWER key.
2. The call is extended to the desired station in normal fashion.
Service Conditions
1. CCSA trunks are physically the same as those used for tie trunks. The CCSA trunks may be push-button
or rotary in either direction.
2. Careful consideration should be given to system numbering plans before assigning CCSA ACCESS codes
to avoid numbering conflicts.
3. CCSA ACCESS codes can be either one or two digits.
4. Pad control can be used on a CCSA call. Refer to TIE LINE CONNECTION WITH PAD CONTROL [T-
5] .
5. LEAST COST ROUTING - 3/6-DIGIT [L-5] may access a CCSA trunk group for off-net calling only.
6. Tandeming through on a CCSA network requires an Attendant and TRUNK-TO-TRUNK
CONNECTION [T-10].
Programming
ARTD - For CCSA TIE Line routes, assign CDN 6:TCL, TRUNK CLASS as a CCSA route:
RT:1
1-OSGS
:2/7 2-ONSG :3 3-ISGS :2/7 4-INSG :3 5-TF :3
6-TCL :5 7-L/T :1 8-RLP :2 15-LSG :5/8*
Note: Assign “5” for TIE Lines and “8” for DID trunks. For all other programming, see TIE LINE ACCESS
[T-3].
