9. Analog and VoIP Line PCBs
o See Worksheet 4: CO Line
o RDDU, RCOU, RCOU with RCOS, RGLU, REMU, and BVPU: Each PCB or PCB
combination requires one slot. These PCBs can not occupy a slot that is left vacant to provide
capacity for RDTU, RPTU, or RWIU as shown in
provides up to four circuits for the type of lines it supports, except RCOU with RCOS which
provides eight circuits.
10. ISDN BRI Digital Line PCBs
o See Worksheet 4: CO Line
o RBUU, RBUU with RBUS, RBSU, RBSU with RBSS: Each PCB or PCB combination
requires one slot. These PCBs can not occupy a slot that is left vacant to provide capacity for
RDTU, RPTU, or RWIU as shown in
BRI circuits (four lines) and combination PCBs provide four BRI circuits (8 lines), for the type
of BRI Line it supports. Each ISDN BRI circuit provides two lines for the DK system.
