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 2-54 and 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 2-54 and 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 2-54 and 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
• Check systems capacities in Tables 2-3~2-7 to confirm the features to be used are within
limitations.
