Worksheet 2
After completing Worksheet 2, follow Worksheet 3 guidelines to configure miscellaneous items.
Notes:
Station PCBs include: PDKU, RDSWRSTS, RSTU, RSTU2, PEKU, P E W , and PSTU. When
installing PDKUl and PDKU2, see Worksheet 2, Table 1-8 (Example) for configuration requirements
regarding OCA, RPCI-DI, PDIU-DUDS, and PDKU1. All station PCBs use four to eight station port
software time slot requirements.
2. Ground and loop start CO line PCBs include RCOU/RCOUS, RGLU, PCOU, 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 1-70 (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.
Option PCBs that require a cabinet slot include PIOU, PIOUS, PEPU, RSIU, RSSU, and RCIU.
3.
4. Tie and DID line PCBs include: REMU, RDDU, PEMU, and RDTU. tie/DID line PCBs. These PCBs
use station ports and CO line ports in DK280 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
sequences. If installing an RDTU, see Worksheet
RDTU slot requirements.
5. If installing RDTU (TI) 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 1
General Note:
The maximum number of station ports used by station, PC attendant console, tie, and DID PCBs can not
exceed the following quantities:
In some rare configurations, when using RDTU (Tl) 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 tie/DID channel used. RCIU/RCIS PCBs do not take from or use station ports or CO line software time
assignments.
