CENTRACOM to MLC 8000 through CTI

The following scheme describes the connection of CENTRACOM to MLC 8000 when CENTRACOM receives Channel Activation indication. This connection requires additional CTI logic converter hardware to transfer the voltage properly between the MLC and the console.

NoteThe CTI part number is S2-61418. The Motorola drop-ship part number is DSS261418.
4-Wire MLC 8000 to CEB Cabling Including CTI E&M
NoteFor Repeat On/Off and PTT from console, the connections through the punchblock are optional. For distances beyond 200 feet or in another building, the CTI is required.
NoteSee the following tables for more information about the customer site auxio connection.

The following is an example of a CENTRACOM to MLC 8000 with CTI connection. Note the punch blocks and the cabling.

CENTRACOM to MLC 8000 with CTI Sample Connection
NoteFor Cable A, use the open-ended cable with the punch block. In the previous figure, the CTI is connected to P3, but this can be P1 as well, based on the card cage connection.

Note(*) Pin numbers are dependent upon the cardcage slot in which the BIM card is installed. See BIM Audio Connections through PTT from Console Connections to BIM for the correct PIN numbers.
ImportantNote that the 4-wire has two pairs. You configure each pair to be either the output or the input audio. This configuration is done at the CENTRACOM.
