2) OPTION 2: Eight digital telephones with DIU
or OCA: this option uses bdth 6 channels for
each circuit to interface up to eight lOOO-
series digital telephones; plus each telephone
may have an integrated Data Interface Unit
(PDIU-DI) or Off-hook Call Announce PCB
(DVSU) installed. In addition, this option sup-
ports the stand-alone Data Interface Unit (PDIU-
DS). One B channel for each circuit interfaces
a single PDIU-DS. The other B channel of this
circuit cannot be used. A single PDIU-DS only
may be installed per each circuit.
1 3) OPTION 3: Four digital DSS consoles only: this
option uses one of the B channels for each of
the two circuits to interface up to four lOOO-
series digital DSS consoles.
1 4) OPTION 4: Eight digital DSS consoles only: this
option uses both B channels for each of the two
circuits to interface up to eight lOOO-series
digital DSS consoles.
NOTE:
1. When using option 2 or 4, the next highest
numberadjacentPCBs/otcannotbeused.
For example, if an NDKU is installed in LO1
or UOl, the PCB slot LO2 or UO2 respec-
tively, must be left vacant.
2. When using option 4, program the first four
DDSSs on circuits 7, 3, 5 and 7 on the
NDKU PCB. Program the second four
DDSSs on cirucits 1, 3, 5 and 7 on the
adjacent slot next to the NDKU PCB.
3. When using option 4, wire the first four
DDSSs to circuits 1,2,3 and 4 on the NDKU
PCB(thesearetheNDKUassignedDDSSs)
and the second four DDSSs to circuits 5, 6,
7 and 8 (these are the DDSSs assigned to
the adjacent slot) on the NDKU PCB.
3.46 The NOCU PCB is installed at a rate of one
PCB for each group of eight electronic telephones.
There are no strapping options on this PCB. The
NOCU is installed in any of the line designated slots
LOO m Lll and/or L15 m L26 in PERCEPTION,, and
in any designated slots UOO m U31 in PERCEP-
TION,,. If any of the eight circuits is not used for
Off-hook Call Announce, the remaining circuits
CANNOT be used for other electronic telephone
assignments.

3.51 Install the NSTU in any of the line designated
slots LOO w Lll or L15 w L26 in the PERCEPTION,
system. The designated slots in PERCEPTION,,
