BWDKU1A – Digital Telephone Interface Unit

BWDKU1A – Digital Telephone Interface Unit

Circuits per PCB: 16 digital telephone circuits

Interfaces with: all Toshiba digital telephones (corded and cordless, DDCB, DSS, ADM, BPCI)

CAUTION! Existing SpectraLink interface units are not compatible with the BWDKU1A. A firmware update will be available from Spectralink in the near future.

When installing Add-on modules, be sure to check Table 10-1 on page 10-2to verify maximum line lengths. BWDKU supports 1 pair wiring per Table 10-2 on page 10-6.

Older Version(s): none

The BWDKU1A is very similar to the BDKU + BDKS, but it supports 16 DKT circuits with a single PCB. It is also compatible with Strata DK but only supports eight circuits.

BWDKU1A Installation

1.See Table 6-8and Figure 6-12, then make any jumper adjustments needed for DKT or slot requirements. The BWDKU1A can be installed in any slot; however, if it is installed in expansion slots S_07~S_10, you must move the jumper plug to the “8 CCT” position.

Important! Do not detach the SWDR1A subassembly. The BWDKU1A will not work properly without it.

2.Insert the BWDKU1A (component side facing right) into the appropriate slot, and apply firm, even pressure to ensure proper mating of connectors.
