BDKU Hardware Options

BDKU can be equipped with a BDKS piggyback PCB to provide a total of 16 circuits. Refer to Chapter 11 – Station Apparatus for instructions on how to connect digital telephones, DDCBs, and DDSS consoles to the BDKU/BDKS, as well as how to upgrade digital telephones with these options: a PC Interface Unit (BPCI), a Speaker Off-hook Call Announce upgrade (BVSU), and a Headset/External Speaker (BHEU). The BDKU can be installed alone, or with the BDKS subassembly.

BDKS

The BDKS can be installed onto the BDKU to add eight more digital telephone circuits.

To install the BDKS

Match the BDKS connectors to the BDKU, as shown in Figure 6-4. Press firmly to ensure that the connectors are snug.

BDKU Installation

1. Set the BDKU/PDKU switch for the appropriate system (refer to Figure 6-4and Table 6-3).

2. Insert the BDKU2 (component side
facing right) into the appropriate slot,
and apply firm, even pressure to
ensure proper mating of connectors.
Refer to “Worksheet 6: Strata
CTX670 Cabinet Slots” on page 2-37
to ensure the BDKU is in a suitable
slot.

3. Install the Ferrite Core (comes with
the BDKU) onto the 25-pair cable
that connects the BDKU to the MDF:
Flip open the two snaps on the Ferrite
Core, then snap it shut around the
BDKU cord as shown in Figure 6-3.		5845
The core must be as close as possible
to the BDKU.
The core is needed to comply with
FCC requirements.
4. Some Ferrite Cores require a tie-wrap	Figure 6-3	BDKU Ferrite Core
at the bottom to keep it from sliding.
For those, feed the tie-wrap through
the slots in the Ferrite Core, then cinch it.
