Important!
The correct placement of TRs on the Passive Bus is critical to ISDN BRI circuit
operation (see the following TBSU and RBSU/RBSS Passive Bus configurations
section).
TBSU and RBSU/RBSS Passive Bus Configurations
The placement of S-type TE and TA devices on the BRI S-passive bus is critical for good TBSU
and RBSU/RBSS BRI circuit performance.
show four passive bus
architectures that are known to work. In all installations, follow the guidelines of any of these
passive-bus models using the wire, cables, and jacks described in the previous paragraphs.
