Feature Key (KKYS)
The system can be upgraded with an optional feature key, the KKYS, which installs onto the
K5RCU PCB in the Base KSU. The KKYS1 provides Automated Attendant (AA); KKYS2
provides AA and ACD; and KKYS3 provides AA and ACD/MIS.
SMDR, SMDI, ACD/MIS and Maintenance DKi Admin/Modem (TTY) Interface
(TSIU)
The TSIU PCB provides two RS-232 interface ports (modular jacks) that allow the DK40i system
to connect to an SMDR Call Accounting device, a DKi Admin PC or external modem for system
maintenance/administration, ACD/MIS reports using Toshiba’s Insight DK software, or an SMDI
interface for Voice Mail. It does not have a built-in modem capability.
Only one TSIU can be installed per DK40i system. When the TSIU PCB is installed, the PIOU can
still be installed for zone paging, control relays, and an SMDR RS-232 interface, built-in (IMDU)
maintenance modem, ACD/MIS processor or VM SMDI or maintenance interface.
Expansion KSU Architecture
The optional Expansion KSU, which attaches
easily to the side of the Base KSU, offers four
universal slots that can host a variety of line and
telephone PCBs (see Figure 7). See Chapter 4 –
Universal Slot PCBs for descriptions of PCBs.
Station and Line Capacities
This section shows the maximum basic and CO configurations that are possible with the DK40i.
There is a variety of configuration combinations of digital and standard telephones with CO lines,
including loop start, ground start, Tie, and DID lines. Any loop or ground start CO line can be
equipped with Caller ID.
The DK40i Base KSU comes equipped with eight digital telephone station circuits. One of four
optional PCBs can be added to provide either four loop start or DID lines, or two ISDN BRI S/T or
U circuits. Another optional TCIU2 PCB can be added to the Base KSU loop start line PCB to
provide Caller ID interface. An optional KSTU2 PCB can be added to provide four standard
telephone circuits (ports).
An optional Expansion KSU can be added to the DK40i to increase the system capacity to 28
station ports and 12 CO lines (see Figure 5). A maximum of 28 station ports and 12 CO line
interfaces are allowed in the system (Base KSU plus Expansion KSU). Base capacity is 12 station
ports and 4 CO line or 2 BRI circuit interfaces.
