Cables are provided according to the connectors on the RRCU card to which they are attached.
See Table 1-15 for connector information.
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 RPTU.
Step 4:
ISDN PRI Digital Line PCBs
RPTU must be placed in designated slots as described below. The RPTU PCB can provide up to 30
ISDN PRI lines. The RPTU PCB can be installed into any of the following slots. Please note that the
slot on the right hand side next to the RPTU PCB MUST be kept vacant.
Important!
RPTU2 is required for QSIG Networking.
Step 5:
Digital and Standard Telephone Station PCBs and the Stratagy DK Voice Mail
PCB
◆
BDKU (+ optional BDKS), PDKU, RSTU, RDSU/RSTS and the Stratagy DK: Each PCB or PCB
combination requires one slot. Refer to the Notes under the cabinet diagram in “Strata CTX670
Cabinet Slot Configuration” to determine into which slots these PCBs can be installed. BDKU/
BDKS, PDKU, RSTU and RDSU/RSTS PCBs cannot be installed in slots left vacant for 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.
Step 6:
ISDN BRI Digital Station 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 is left vacant to provide capacity for
RPTU. 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.
