Figure notes:
1.	Part of terminating resistor block	7.	Basic multi-point option
2.	White or purple field	8.	4-pair horizontal cables
3.	Part of 4-pair blue field	9.	Row “A”
4.	From ISDN T-interface circuit (2-pair)	10.	Row “B”
5.	To ISDN S/T-interface terminals	11.	Row “C”
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.
