Determine Caller ID FSK receiver/decoder PCB / Slot Requirements
C5.3
Total Ground/Loop Start Line with caller
A = Total RCIU/RCIS PCB (Slots) =
General Note:
RClU provides four caller ID receiver/decoder circuits. RClU with RClS subassembly provides
eight caller ID receiveddecoder circuits. Always use RClU with RClS for up to eight circuits as
opposed to using two RClU PCBs. These circuits do not use up station port or CO line software
assignments.
Determine Analog Tie Line PCB / Slot Requirements
C5.4
Total analog tie lines (with or without ANVDNIS) needed:
CT =Total REMU or PEMU PCB (Slots) =
General Notes:
REMU provides four E&M tie trunks (Type I or I1 signaling, Wink or Immediate Start, 2- or 4-
wire transmission).
The PEMU 1 can also be used. The PEMU only provides Type I signaling, 2- or 4-wire
transmission and Immediate Start.
See Table
station port line and capacity by four ports and four lines.

Determine Analog DID Line PCB (Slot) Requirements
Total DID lines (with or without ANVDNIS) needed:
General Notes:
RDDU provides four Direct Inward Dialing lines. (Each RDDU reduces system station port and
line capacity by four ports and four lines.)
See Table 1-2 for RDDU maximum quantities.
