Total PDKU PCBs (Slots)
PDKU provides eight digital telephone ports (circuits). Circuit 5 (when associated with ports
004, 0 12, 020, and 028) can only interface with a DDCB. Circuit 8 can only inferface with a
DDSS console (see Table 1-6).
The PDKUl can also be used. The PDKU 1 can only support Data Interface Units (DIUs) on
-
circuits 1 7, while the PDKU2 can support DlUs on all eight circuits. See Worksheet 2 ,
Table 1-8 (Example) for slot limitations.

The PSTU2 or PSTU 1 can also be used. These earlier version PCBs can interface with the
same devices that the RSTU can, but they have different ring generators and cannot support
The RSTU provides eight standard telephone ports (circuits). Circuit 2 only can connect
to a separate Background Music (BGM) source. The RSTU can be equipped with an R48S to
extend the loop length of the RSTU from 600 ohms to 1200 ohms (see Table 1-4).
Total RDSU PCBs
Total RSTS PCBs
RDSU provides two standard telephone ports (circuits) and four digital ports (circuits) in its
basic configuration. The optional RSTS can be attached to the RDSU to provide two more
standard telephone ports. The RSTU can be equipped with an R48S to extend the loop length
of the RSTU standard telephone ports from 600 ohms to 1200 ohms (see Table 1-4).
PEKU provides eight electronic telephone ports (circuits). Circuit 5 (when associated with ports
004, 012, 020, or 028) can only interface with an HDCB. The HDSS consoles requires two
circuits, circuits 7 and
8,
circuits 2 and 3 of a PEKU.
