Figure 58: Typical Installation of Terminating Resistor Block
Figure notes
1 Part of terminating resistor block
2 White or purple field
3 Part of 4-pair blue field
4 From ISDN T-interface circuit (2-pair)
5 To ISDN S/T-interface terminals
6 2-pair cross-connect
For point-to-point wiring, the top row connects to the blue station field. The pair connects from the
110RA1-12 to the standard 4-pair circuit. Pair 1 from the 110RA1-12 is connected to Pair 1 of the station
field, and Pair 2 is connected to Pair 3 of the station field.
Two terminal basic multi-point applications are accommodated by connecting row B (output) to the
second terminal common to the multi-point circuit.
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 two 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.
