After completing Worksheet
2,
follow Worksheet 3 guidelines to configure miscellaneous items.
Notes:
Station PCBs include: PDKU,
RSTU,
PEKU,
and PSTU. When
installing
and
see Worksheet 2, Table 1-8 (Example) for configuration requirements
regarding OCA,
and
All station PCBs use four
to eight station port
software time slot requirements.
2.
Ground and loop start CO line PCBs include
RGLU,
and RDTU. Do not
install tie or DID line PCBs because they use station ports and will cause station port shifting. If
installing RDTU (TI) PCBs, see Worksheet
2,
Tables
1-9
(Example) and
(Example) for RDTU
slot requirements. Always atfempt to install RDTU PCBs starting with cabinet slots that only require
two slots to allow all 24-channels to operate. All
CO PCBs use from 4, 8, 26 or 24
CO line software
time slot assignments.
3.
Option PCBs that require a cabinet slot include
PIOUS, PEPU, RSIU, RSSU, and RCIU.
4.
Tie and DID line PCBs include:
RDDU, PEMU, and RDTU.
line PCBs. These PCBs
use station ports and
CO
line ports in
software, so they should
not
be installed in lower
numbered slots than station PCBs whenever practical. This will prevent station port number shifting
which could cause problems with
station directory number,
or Primary Directory Number
sequences. If installing an RDTU, see Worksheet
2,
Tables
1-9
(Example) and
1-70
(Example) for
RDTU slot requirements.
5.
If installing RDTU
PCBs, it may be required to skip certain slots. In this case, these slots must
be skipped and remain vacant. See Worksheet
2,
Tables 1-9 (Example) and
-
(Example).
General Note:
The maximum number of station ports used by station,
attendant console, tie, and DID PCBs can not
exceed the following quantities:
RCTUA
=
RCTUB or
=
80 maximum
=
240
maximum
In some rare configurations, when using
RDTU
tie or DID lines in systems, the maximum number of stations
allowed may be reduced because the
RDTU PCB takes up two or three cabinet slots and one station port per
RDTU
channel used.
PCBs do not take from or use station ports or CO line software time
slot
assignments.
