Program *12 – CESID Station Information
8-12 Strata DK Programming 5/00
will vary, so you must get the format from the CAMA trunk provider in order to set the CESID
information in this program.
Example formats in which the DK is expected to send digits out the CAMA trunk on E911 calls
are as follows:
1. When the CAMA trunk is connected to the Public Switched Telephone Network:
CESID digits may be: 0-NYY-XXXX
Note The hyphens are for clarity - do not try to program them in *12
0 = Information code expected from a PBX on E911 calls. This multi-frequency (MF) “0”
digit is sent automatically by the DK digits are entered for the calling port in Program *12.
NYY = Office Code
XXXX = Station Directory Number
2. When the CAMA trunk is connected directly to the Public Safety Answering Point (PSAP) the
CESID digits may be: NXX-NYY-XXXX
NXX = Area Code
...or the PSAP serving multiple area codes will substitute a single digit representing an area
code.
NYY = Office Code
XXXX = Station Directory Number
3. If no digits are entered for a port in Program *12, the DK sends an MF digit of “2.”
