Strata CTX Configuration

Worksheet 6: Strata CTX670 Cabinet Slots

Step 7: ISDN BRI Digital Station PCBs

See Worksheet 3: CO Line to determine BRI station PCB requirements.

RBUU, RBUU with RBUS, RBSU, RBSU with RBSS: Each PCB or PCB combination requires one slot. These PCBs can be installed in any slot, except a slot is left vacant to provide capacity for RDTU, BPTU or RPTU as shown in Tables 2-54and 2-55. Each single PCB provides two BRI circuits and combination PCBs provide four BRI circuits, for the type of BRI stations it supports. Each ISDN BRI station requires one BRI circuit.

Step 8: Analog and VoIP Tie Line PCBs

See Worksheet 3: CO Line to determine Analog and BVPU line PCB requirements.

RDDU, RCOU, RCOU with RCOS, RGLU, REMU, and BVPU: Each PCB or PCB combination requires one slot. These PCBs can be installed in any slot, except a slot that is left vacant to provide capacity for RDTU, BPTU or RPTU as shown in Tables 2-54and 2-55. Each PCB provides up to four circuits for the type of lines it supports, except RCOU with RCOS which provides eight circuits.

Step 9: ISDN BRI Digital Line PCBs

See Worksheet 3: CO Line to determine ISDN BRI line PCB requirements.

RBUU, RBUU with RBUS, RBSU, RBSU with RBSS: Each PCB or PCB combination requires one slot. These PCBs can be installed in any slot, except a slot that is left vacant to provide capacity for RDTU, BPTU or RPTU as shown in Tables 2-54and 2-55. Each single PCB provides 2 BRI circuits (four lines) and combination PCBs provide four BRI circuits (8 lines), for the type of BRI Line it supports. Each ISDN BRI circuit provides two lines for the Strata CTX system.

Step 10: Power Factor

After the Cabinets are configured calculate the power factor of each cabinet using Worksheet 7

– System Power Factor Check.

Step 11: Check Systems Capacities

Strata CTX Configuration

Check systems capacities in Tables 2-3~2-7to confirm the features to be used are within limitations.
