Bay Control Card III
Brief Description
The design of the Bay Control Card III (BCC III) is similar to the design of the PRI card. The BCC III has three sites for add-on modules. The sites have connectors to support the modules. The BCC III has site 1 for the FIM II (CIM or Maintenance module), site 2 for the T1/E1 module, and site 3 for the DSP module (single). The FIM II sits back from the BCC III faceplate. The CIM and Maintenance module sit close to the faceplate. The BCC III determines the presence of each module by accessing the module ID information. Unlike the PRI card, the BCC III does not have an S1 switch that you must set to identify the clock source; the BCC III sets the clock source automatically with the presence of the FIM II or CIM.
Note: With software loads earlier than LIGHTWARE™ 19 Release 3.2, BCC III cards will not start properly in an SX-200 ICP MX system if they are located between Bays 8-15. To resolve this issue, relocate the BCC III card to any bay between 1-7, upgrade the software load, and then relocate the BCC III card to any between 1-15 as it should now start properly. For more information, refer to Upgrading an SX-200 LIGHT to an SX-200 EL System.
The BCC III is installed in an SX-200 ELx cabinet.
CAUTION: This card must not be inserted or removed with the power on.
Functions
The BCC III has the same functional characteristics as the BCC II, plus the extra processing power for PRI plus the extra functionality that the software and the hardware installed on the BCC III provides.
The BCC III has three sites for add-on modules. The modules are T1/E1, DSP (single), FIM II, CIM, and Maintenance. The T1/E1 module provides up to 48 channels of T1/D4 connectivity that the present T1 card provides. The DSP module provides CLASS generators for ONS/CLASS sets, conference bridges for Record a Call, and 16 DTMF receivers. The FIM II and the CIM provides a connection from the BCC III in a peripheral bay to the FIM or CIM in the main control cabinet.
