DK424i

Remote Expansion Cabinet Unit

Option interface cards for the DK424i are shown in
Table 6-16 DK424i Interface PCB Options
Zone page interface (unamplified, 4 zones)
Unamplified page output (single zone, 600 ohms, duplex)
Amplified page output (single zone, 3 watts, 8 ohms)
Night transfer or Music-on-hold control relay
Door lock or external amplifier control relay
Alarm Sensor
Remote maintenance modem subassembly (IMDU or RMDS)
(disables TTY output when they are piggy-backed onto the PIOU/
PIOUS or RSIU/RSIS cards)
Remote Maintenance using customer-provided external modem
(requires TTY output port)
SMDR output (RS-232/6-wire modular connector)
MIS for ACD (requires TTY output port)
Voice Mail SMDI (requires TTY output port)
StrataControl and/or DKi Admin PC (requires TTY output port)
Hospitality Management Information System (HMIS)
1. PIOU, PIOUS, and RSSU each provide one TTY port which can be flexibly programmed for the features marked with X.
RSIU/RSIS can provide up to four flexible TTY/SMDR ports.
2. Maintenance modem, ACD/SMIS, Insight DK, Voice Mail, SMDI and DKi Admin PC Interface each require a separate
TTY output. PIOU, PIOUS, and RSSU provide one TTY output each. RSIU with RSIS PCBs provides up to four TTY
outputs.
3. SMDR output will function simultaneously on the same PIOU or PIOUS with one of the following: DKi Admin, remote
modem, SMIS for ACD, Insight DK, or SMDI features.
4. Insight DK, Call Center Viewer and SMIS for ACD requires that the system processor must be equipped with an RKYS3 or
higher feature key.
5. HMIS requires the system SMDR and maintenance ports. If HMIS is in use, local/remote system programming with a PC is
not available.
Remote Expansion Cabinet Unit
The RRCU PCB enables a DK424i Expansion Cabinet to be located up to three kilometers from its
Base Cabinet. One RRCU connects to up to two ribbon-type Data Cables and applies the inter-
cabinet signal to a fiber-optic pair. One fiber pair can support one or two expansion cabinets in one
remote location using one RRCU in the Base Cabinet and another in the Remote Expansion
Cabinet.
A DK424i Base Cabinet will support up to four RRCU PCBs. A DK424i will support up to four
Remote Expansion Cabinets.
Remote cabinets support all line and trunk interfaces. Network clock signals can only be derived
from digital trunks installed in the Base Cabinet (Master) location.
One BDCL cable set is required for each RRCU (master and slave) except for the daisy chain
configuration where only one BDCL cable set is required at the intermediate site.
