C-21 Code Calling Access
General Description
This feature provides the ATTENDANT CONSOLE [A-3] and users dial access to Code Calling equipment.
Operating Procedure
1. Go off hook; receive dial tone.
2. Dial the CODE CALLING ACCESS code.
3. Dial the code number for the unit desired.
Service Conditions
1. Amplifiers, speakers, and Code Calling units must be provided by the customer.
2. Loop Start Central Office trunks are used for interfacing Code Calling equipment. One Central Office
trunk circuit is required per paging port and per answer back port.
3. Fully Restricted Stations: A fully restricted station may make only dial “0” and station-to-station calls;
therefore, the CODE CALL ACCESS is denied.
4. HOTLINE [H-1]: A hotline station user can be programmed to connect to a Code Call Unit when the
station goes off-hook.
5. ROUTE RESTRICTION: A station that is Code Calling route restricted is denied dial access to the Code
Call unit. Restricted calls are routed to reorder tone. If allowed by the user's Class of Service, Attendant
assistance can be used to complete a code call for a route-restricted station.
6. Attendants, users and TIE trunk users can dial an access code and a 2 or 3-digit called party code to activate
a coded signal.
7. The D
term
display will indicate the elapsed call time and trunk number.
