Installation Procedure
Always unplug the keyset line cord before installing a daughterboard.
1. Place the keyset face down on a flat surface.
2. Remove the two knockouts marked "Expansion Module" on the base using a flat-bladed
screwdriver or similar tool.
3. Position the daughterboard over the Expansion Module connectors on the base and push it
onto the base.
4. Secure the daughterboard onto the keyset using the screws provided.
If you removed cables from cable runs, replace them as required.
Connecting Devices To OfficeServ500 Daughterboards
There are two methods for connecting devices to keyset daughterboards. The simplest method
is to connect a device (e.g. another keyset) directly by means of an RJ11 line cord using the jack
on the daughterboard. (If connecting a single line telephone, use a line cord fitted with a master-
ing unit.)
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.

DCS Keyset Daughterboards

There are two types of daughterboard which can be installed in a DCS (Euro) 12- or 24-button
keyset only: a KDB-DLI or KDB-SLI.

KDB-Digital Line Interface (KDB-DLI)

The KDB-DLI provides one additional DLI circuit for the connection of any digital station device
such as another keyset, an add-on module or door phone interface module. The KDB-DLI will
only operate when the keyset is connected to an 8-port DLI card so that it can use the second B
channel. Each port on this card is intended for connection to one telephone.
CAUTION: Connecting multiple telephones to a port may result in incorrect operation or
damage to the card.
