Step 5: ISDN PRI Digital Line PCBs

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

The BPTU or RPTU must be placed in designated slots as shown in Table 2-55. The BPTU or RPTU PCB can provide up to 16 or 23 ISDN PRI lines. The BPTU or RPTU slot provides 16 PRI lines, an additional seven lines requires that the cabinet slot adjacent to BPTU or RPTU be vacant. Up to 11 RDTU PCBs can be installed in a fully expanded system.

Important! BPTU1 or RPTU2 is required for QSIG Networking.

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

2.The slot occupied by RPTU supports 1-16 channels; the slot adjacent to RPTU must be vacant if channels 17 through 23 are needed.

Step 6: Digital and Standard Telephone Station PCBs and the Stratagy DK Voice Mail

PCB

•See Worksheet 2: Standard Telephone, Stratagy DK, IVP8 to determine station PCB requirements.

•BDKU (+ optional BDKS), PDKU, ASTU, BSTU, RSTU, RDSU/RSTS and the Stratagy DK: Each PCB or PCB combination requires one slot. Refer to the Notes under the cabinet diagram in Worksheet 6: Strata CTX670 Cabinet Slots to determine into which slots these PCBs can be installed. BDKU/BDKS, PDKU, ASTU, BSTU, RSTU and RDSU/RSTS PCBs cannot be installed in slots left vacant for RDTU or BPTU or RPTU. Each PCB provides up to eight circuits for the type of stations or Voice Mail ports it supports, except BDKU with BDKS which provides 16 circuits for digital telephones.
