3.14.3 Conventional Channel Configuration

NOTE

After all conventional channels have been configured, saved, and sent, a CEC/IMC Manager-based System Manger database transfer of the conventional channel information is recommended. See SYSTEM MANAGER DATABASE UPLOADS on page 3-14 for details. After completing the transfer, privilege lists of consoles which may require access to conventional channels should be updated by adding the required conventional channels to each console's privilege list. Refer to Console Privilege Lists on page 3-123 for details. Console conventional channel communication modules can then be "built" or "modified" as required.

The basic function of the CIA rack is to add, on a per-channel basis, tone or DC control signaling required for remote-controlled conventional base station operation. It also programs each channel's receive signaling for either voice activation (VOX) or carrier activation (COR). Within the CIA rack, these functions are provided by CI Board channels. Unity gain exists for the audio signals routed through a CI Board channel to/from a VMIM Audio Board channel; therefore, no CI Board channel audio signal level adjustments are required since the VMIM provides these level adjustments. Control signaling related level adjustments and other conventional channel-related parameter settings such as 2/4-wire selection are provided by the Conventional Channel Configuration dialog box. As previously stated, settings made from this dialog box effect CCI and CI Board configurations.

Conventional channel parameters are configurable on a per-channel basis. For example, VMIM/CIA 1 channel 1 may be configured to interface to a tone-controlled conventional base station and VMIM/CIA 1 channel 2 may be configured to interface to a DC- controlled conventional base station.
