(PDKU: Versions 1 & 2)
The PDKU provides eight ports (circuits) for digital
telephones (with or without RPCI-DI, integrated data
interface units and add-on modules), a digital door
interface units (PDIU-DS), and
selection console (DDSS). There are
the PDKU: the PDKUI and the PDKU2. These
versions are identical, except for the following
distinctions:
The original PDKU version, the PDKU1 cannot
support Data Interface Units (DIUs) on Circuit 8.
The later version PDKU2 can support DlUs on
each of its circuits.
PDKUI can only be installed in slots S11
-
S21 S26, S31 S32, S41
-
and S61 S66. PDKU2 can work in any slot. See
Table 1-8 of Worksheet 2 in Chapter 1-
