The following slides have sample BTS configurations. The possibilities are so many. Huawei BTS supports configurations from 1/0/0 to 24/24/24 with use of extra antennas

The new cabinet is equiped with antenna ports to support 6 cells (the BTS supports 6 cells). As a result one cabinet of a dual band site usually has both the 900 and 1800 cells eg 222/222 is configured in BTS312 cabinet

The SCU always works with a CDU (the CDU provides Received signals to TRXs)A cell that has six TRXs is configured as an Overlaid/underlaid cell because the TRXs combined through the ESCU lose an extra ~4dB and should be configured in the overlaid subcell. The BCCH must be configured on the underlaid subcell to maintain the coverage of the cell.Where a cell has only 2 TRXs, if coverage is desired, an EDU should be used instead of the ECDUA cell that has six TRXs is configured as an Overlaid/underlaid cell because the TRXs combined through the ESCU lose an extra ~4dB and should be configured in the overlaid subcell.
