Install multi-point adapters
Use multi-point adapters to provide signal fanout of the T-interface. BR851-B or
the 367A perform fanout at the work station. These adapters support more than 1
ISDN terminal per horizontal 4-pair D-inside wire (DIW). To support multiple
horizontal runs, a MDF with multiple common rows performs fanout in the satellite
closet. The 110RA1-12 provides fanout for 2 horizontal runs and contains the 100
Ohm terminating resistor. Use this for basic multi-point or point-to-point with
terminating resistor in the closet. Other fanout blocks include the 110AB1-025M
and the 110AB1-050M.
BR851-B adapter (T-adapter)
The BR851-B supports 2 terminals on 1 multi-point BRI at the work station and is
used to fanout transmission and power. See
