LBI-39101

Relay Outputs (if used)

Form-C relay contacts (single-pole double-throw) are available from the Enhanced Audio Enclosure for external device control. Contact connections are made at the screw- terminal type terminal block on the rear panel labeled "RELAYS". Even though these relays are also controlled from the console’s dispatch keyboard, they are not the same as and they should not be confused with the relays within the CEC/IMC utilized for auxiliary I/O interfacing.

As shown in Table 25, the first relay (relay 1) is activated when the console is keyed (PTTed). During the key, the relay's common and normally-open contacts close and its common and normally-closed contacts open. The second relay's (relay 2) common and normally-open contacts close while <Alt><F10> is depressed at the Dispatch Keyboard. Like the first relay, this relay's action is considered "momentarily" as it is only in the active state when the <Alt><F10> keys are depressed. The third relay's (relay 3) contacts toggle open/close at an <Alt><F9> keystroke from the Dispatch Keyboard. The other relays are not supportedG￿by software.

As required, connect the relay contact outputs to external equipment. See Table 25 and Figure 9. Specified contact rating for all relays is 0.75 amps at 26 Vdc. Open contact isolation is specified to 500 Vrms at 60 Hz. Isolation between any relay terminal and the Enhanced Audio Enclosure's ground is also specified to 500 Vrms at 60 Hz.

Enhanced Audio Enclosure

Call Director (if equipped)

As shown in Figure 1, all C3 Maestro-to-Call Director interconnections at the console are made at the Enhanced Audio Enclosure's connector labeled "CALL DIR". A Call Director telephone patch also requires an additional 4-wire balanced line between the Enhanced Audio Enclosure and the console’s CIM within the CEC/IMC. At the CEC/IMC, CIM audio channel/line four (4) is used for Call Director interfacing. CD control data interfacing is handled over the existing RS-232/RS-422 serial control data interface between the PC and the CEC/IMC. Therefore, no additional control data link must be added to support Call Director patch equipment. Refer to Figures 1, 5, 6 and 10 for interconnection details and the following discussion on CEC/IMC line audio line requirements.

Console-to-CEC/IMC Audio Interconnections

All CEC/IMC line audio in to and out of a C3 Maestro dispatch console system enters and leaves via the DB-25 connector labeled "LINES 1 - 4" on the Enhanced Audio Enclosure's rear panel. If the console is connected to a Call Director, Line 4 between the Enhanced Audio Enclosure and the CEC/IMC must be established for CD audio routing between the console and the CEC/IMC. In this case, the third unselect speaker audio is not available.

Table 7 describes the audio signals between the Enhanced Audio Enclosure and the CIM within the CEC/IMC. The descriptions are relative to the Enhanced Audio Enclosure. All signals on these 600-ohm pairs have typicalG￿levels between -5 dBm to 0 dBm.

If not accomplished in the previous instructions in this manual, install a 4-wire balanced line (two pairs) between the required CEC/IMC Audio Concentrator Card and Enhanced Audio Enclosure. Refer to the section entitled "CEC/IMC INTERCONNECTIONS" for details (page 11). In most cases, the pre-wired 100-foot audio cable (part number 19B804083P2) is utilized as described in the "Audio Links" subsection (page 14).

Console-to-Call Director Interconnections

Table 8 describes the various signals between the Enhanced Audio Enclosure and the Call Director. The descriptions are relative to the Enhanced Audio Enclosure. All Enhanced Audio Enclosure connections are made at the "CALL DIR" female DB-9 connector. Figure 10 and Table 13 indicateG￿the connector's pin-out.

Interconnect the Enhanced Audio Enclosure to the Call Director as required per Tables 8 and 13, Figure 10, and the Call Director's documentation.
