tion stored in the CNI GETC personality EEPROM. When
a conventional transmission is received, the GETC decodes
the analog Channel Guard tones and associates the tone
with an EDACS GID. The inbound Channel Guard tone is
defined in the personality EEPROM along with a corre-
sponding GID in the EDACS System.When the CEC/IMC
transmits a Group Assignment, the GETC converts the GID
to an outbound conventional transmission with its corre-
sponding analog Channel Guard tone. The analog Channel
Guard tone is generated in the GETC and sent to the re-
peater to accompany voice for transmission.
The CNI option may be installed in a conventional
MASTR II or IIe (option STCP3Z) or MASTR III (option
SXCP5T) repeater that uses EIA RS-220A Channel Guard
tones. The options include the following major components
with associated hardware, interconnect cables, and modifi-
cation instructions:
• GETC Shelf 19D901868G3
(using GETC Logic Board 19D904266)
• Turbo Board 19D903536P1
• Rockwell Modem 19A705178P1
• CNI GETC PROM Kit 344A3497G1
