TBUU and RBUU/RBUS Wiring Guidelines

o DK BRI-U interface circuits can be configured to connect to an ISDN line circuit (NT mode,
Line-side) or to ISDN U-type terminal equipment TE1 or terminal adapters TA (LT mode,
station side).
o The configuration of DK BRI-U circuits is accomplished in Program *60 alone - no hardware
jumpers are required on the PCBs. Make sure you run this program along with Program 03
attempting to use the BRI circuits. Program *60 may cause line or station ports to shift on
circuits following the BRI PCBs.
o Install the Toshiba-supplied Ferrite core on each ISDN circuit card per
16-16 on Page
separately.
o For more information regarding the DK BRI-U interface, see "PRI and BRI Overview" at the
beginning of this chapter.
