Step 7:
Analogue and VoIP Tie Line PCBs
◆
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 RPTU. Each PCB provides up to four circuits for the type of lines it supports,
except RCOU with RCOS which provides eight circuits.
Step 8:
ISDN BRI Digital Line PCBs
◆
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 RPTU. 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 9:
Power Factor
◆
After the Cabinets are configured calculate the power factor of each cabinet using “System Power
Factor Check Considerations” on Page 1-27 .
Step 10:
Check Systems Capacities
◆
Check systems capacities in Tables 1-3 ~ 1-8 to confirm the features to be used are within
limitations.
