Cabling and Connectors
Strata DK uses industry standard cabling and connectors to interface with lines, stations, and
peripherals (Table 46 on Page 125).
Stations use standard twisted-pair cabling to connect to the system via the MDF. Digital and
standard telephones require just one pair-cabling, or two pair, if equipped with DADM, RPCI or
DVSU. Electronic telephones need two-pair cabling or three-pair for Speaker OCA.
Station PCBs connect to stations and peripherals with a 25-pair Amphenol connector via the MDF.
CO, DID, and Tie line circuits interface with the public telephone network via modular connectors.
Peripheral devices such as SMDR, DKAdmin maintenance PC, etc., are connected to the interface
PCBs (TSIU, RSIU, PIOU, etc.) with three-pair (six wires) modular cords and the Toshiba PPTC9
or PPTC RS-232-to-modular adapters.
The Strata AirLink Wireless Telephone system configured to standard ports (RSTU2) connects to
all Strata DK systems using the Base Station Interface Adapters (BSIAs) and one or two Base
Stations.
The Strata AirLink Wireless Telephone system configured to digital ports interfaces to the DK40i,
DK424i (standard cabling and connectors) using the proprietary RWIU PCB. The RWIU uses
industry standard RJ11 jacks to support up to four Base Stations. Multiple RWIUs can be installed
to increase the capacity of the wireless system.
