iDCS 64B AOM (See Figure 2–11)• 64 programmable keys with red lights• A maximum of 2 can be assigned to any keyset to provide addi-tional programmable keys• A maximum of 4 per system• Requires a DLI port• Available in dark grayiDCS 14B STRIP (See Figure 2–12)• 14 programmable keys with red lights• A maximum of one can be added to any 28D or 18D keyset to provideadditional programmable keys• Does not require a DLI port• Available in dark grayiDCS KDB-FULL DUPLEX (FKDBF)This is a daughter board that can be installed only in the 18 or 28 button keysets. The standard speakerphonemode of operation for an iDCS keyset is “half duplex”. This means that you cannot transmit and receive speech atthe same time. Adding an FKDBF to your keyset will convert the speakerphone into full duplex mode enhancingits operation. The FKDBF does not require a second “B” channel like the FKDBD or FKDBS and so can be used onany DLI card.Note: Only one KDBF can be installed on a keyset. The KDB-D/KDB-S modules are not supported on the iDCS andDS keysets on the OfficeServ 7100 system.2.9FIGURE 2-11FIGURE 2-12
