that no damage occurs to the keyset PCB. Reattach the base to the keyset and test to
ensure normal keyset operation.
8.5 KDB-SLI
This daughterboard can be installed only in the DCS 12 or DCS 24 button keyset.
Before performing this procedure, unplug the line cord from the keyset and remove the
base wedge. Place the keyset face down on a soft surface and remove the four base
retaining screws (see Figure 8–2). Separate the base from the keyset and place the
keyset aside. Attach the KDb-SLI to the keyset base with the six screws that are
supplied (see Figure 8–6). Take care to ensure that the modular socket shows through
the access hole in the base (see Figure 8–4). Invert the base assembly over the keyset
and plug the ribbon cable into the socket on the keyset PCB (see Figure 8–5) while
making sure no damage occurs to the keyset PCB. Reattach the base to the keyset
and test to ensure normal keyset operation.
8.6 CONNECTING TO THE KDBS
There are two methods for connecting devices to keyset daughterboards. The simplest
method is to connect the second device directly by means of a line cord. See Figures
8–7 and 8–8.
The second method is to use a multi-pair station cable, connecting separate station
jacks to the first two pairs. A line cord can now be connected between the
daughterboard and the second jack. This returns the daughterboard port to the MDF
for cross-connection to another cable run (see Figure 8–9).
