The 12EKT module expands the
Emerald ICE
system capacity of digital ports Deluxe & Standard
Telephones and DSS Consoles. Each digital port is comprised of a proprietary octal ASIC (Appli-
cation Specific Integrated Circuit) transceiver. There are three data channels in operation at each
digital port via the octal transceiver. One channel is used for call processing control of digital termi-
nal functions/operations and two channels are used for the digital voice channel requirements. The
12EKT is controlled directly from the 610+2 Board/Base Board.
Each digital station interface is protected against circuit wiring shorts by an over-current protection
Polyswitch. The digital station circuit requires only one cable pair to operate and is not polarity
sensitive.
Physical connection of digital port terminals (Deluxe & Standard Telephone and DSS) to the
12EKT module is made through a 25-pair amphenol connector along the top edge of the module.
1 Additional 12EKT module can be added to KSU1 and 2 in KSU2.
