Connecting the terminating resistors
DSLs require that a terminating resistor be connected at the end of
each loop. See ISDN Basic Rate Interface Feature Fundamentals
(NN43001-580) for engineering rules and locations of terminating resistors.
The end of the S/T interface loop has an RJ-45 jack to plug in the
telephone cable. Plug the terminating resistor into the RJ-45 jack, and then
plug the telephone cable into the terminating resistor.

plug the cable into the power source's RJ-45 jack. This power
source must supply power only to the local ISDN BRI terminal,
not back into the DSL through the RJ-45 wall outlet. The power
adapter is supplied with the terminal.
Program the terminal parameters, such as the Supervisor
Position ID (SPID) and Static Terminal Endpoint Identifier (TEI),
as required by the type of terminal. For detailed information
pertaining to this procedure, refer to the section "Initialize ISDN
BRI terminals", found in ISDN Basic Rate Interface Feature
Fundamentals (NN43001-580).
Repeat steps 1 and 3 for each terminal to be connected.
Note:
For every port there is one loop with only one terminating resistor
per loop. Each loop can support a maximum of eight telephones.
