Direct Station Selection (DSS) Consoles and Door
Phones (MDFBs)
Up to 12 door phones can be installed in a system with DK424 RCTUB, RCTUC/D and
RCTUE/F, nine with RCTUA. Each is connected to a DDCB or HDCB door phone control box.
See Table 4-20 for door phone configuration considerations.

Notes
DSS (DDSS and HDSS) Console
No additional hardware is required for DSS consoles.
DSS consoles are assigned to associated digital and electronic telephones in programming.
DSS consoles cannot be connected to RDSU or PESU electronic circuits.
Door Phone
DK424 can support as many as 12 MDFBs. See
Each DDCB requires one circuit (Circuit 5) on a PDKU or RDSU, and each HDCB requires one circuit (Circuit 5) on either a PEKU
or PESU.
One door lock control can be configured on each DDCB and HDCB in place of one door phone.

It has 60-buttons which are flexibly assigned as CO line, speed dial,
and DSS (no [PDN] or [PhDN]).

Each Digital Door Phone/Lock control (DDCB) interfaces with up to
three door phones (MDFBs) or two MDFBs and one door lock.
DDCBs/HDCBs can only be connected to Ports 004, 012, 020, and
028, normally in slots 11, 12, 13, and 14, respectively.
Always install DDCB/HDCB station PCBs (PDKU, RDSU, PEKU, or
PESU) in slots that have lower slot numbers than RDDU, PEMU,
REMU2, RATU, or RDTU PCBs.
