Step 3: BIOU Interface PCB

Up to two BIOU PCBs can be installed in any local/remote cabinet slot, except the BIOU may not occupy a vacant slot adjacent to RDTU, BPTU or RPTU. See “Worksheet 4: Page/MOH/ Control Relay” on page 2-26for BIOU functions.

Step 4: T1 Digital Line PCBs

See Worksheet 3: CO Line to determine RDTU PCB requirements.

RDTU must be placed in designated slots as shown in Table 2-54. The RDTU PCB can provide up to 16 or 24 T1 lines. The RDTU slot provides 16 T1 lines, an additional eight lines requires that the cabinet slot adjacent to RDTU be vacant. Up to 11 RDTU PCBs can be installed in a fully expanded system

1.RDTU PCBs do not have to be installed in the order shown in this table. Example: If only one RDTU is needed, it can be installed in any RDTU slot shown in the table so long as the slot is supported by the installed processor.

2.The slot occupied by RDTU supports 1-16 channels; the slot adjacent to RDTU must be vacant if channels 17 through 24 are needed.
