Designated Speaker Oca, Diu Data, And T1 Slots - Toshiba Strata DK14 Installation And Maintenance Manual

DK424 Configuration
System Configuration
DK424 Expansion Cabinets provide six universal slots maximum in any configuration with a
DK280 Base Cabinet, including a DK280 Base Cabinet with an RCTUE/F processor.
DK424 Expansion Cabinets provide eight universal slots in one configuration only: when
connected to a DK424 Base Cabinet controlled by an RCTUE/F processor (MBJU jumper
must be removed - see installation for details). DK424 cabinets provide six universal slots in
all other configurations.
An RCTUE/F processor can be installed in a DK280 Base Cabinet. When an RCTUE/F
processor is installed in a DK280 Base, only five Expansion Cabinets (DK424 and/or DK280)
can be installed. These Expansion Cabinets provide only six universal slots.
All older DK280 Release 1~3 processors will function in the DK424 Base Cabinet. The
features available depend on the respective release and type of the RCTU. These processors
include RCTUA1, RCTUA3, RCTUB1, RCTUB2, RCTUBA3/BB3, RCTUC1/D2 and
RCTUC3/D3.
When an older processor is installed in the DK424 Base Cabinet, the DK424 and DK280
Expansion Cabinets provide six universal slots and the MBJU jumper must be installed -
see RCTU installation for details.
RCTUA in a DK424 Base allows no Expansion Cabinets.
RCTUB or RCTUBA/BB in a DK424 Base allows one DK424 or DK280 Expansion
Cabinet with six universal slots.
RCTUC/D in a DK424 Base allows up to five DK424 and DK280 Expansion Cabinets in
any combination. These Expansion Cabinets provide six universal slots.

Designated Speaker OCA, DIU Data, and T1 slots

DK424 systems require that PDKU2 PCBs that support Speaker Off-Hook-Call-Announce (OCA)
and PDIU-DS and RPCI-DI PCBs for data applications must be placed in the slots designated in
Tables 4-4
PDKU2s that support Handset OCA and RPCI TAPI-only can operate in any slot.
Note
Additionally, to enable T1/DS-1 interface, the RDTU PCB(s) must be placed in certain slots, with
corresponding slots left vacant. (The operation of certain channels necessitates vacant slots.)
RDTU PCBs can be placed in the slots in bold type; the vacant slots are not in bold in the
following tables.
Example: for cabinet 1, if an RDTU is placed in slot 13 and you want to use RDTU channels
17~24, then slot 14 must be left vacant. If you installed a second RDTU, it would go into slot 15;
slot 16 must also be vacant if you want to use RDTU channels 17~24.
