To connect ISDN BRI terminals to DSLs:
1 Plug one end of the modular cable into the ISDN BRI interface
connector on the terminal and the other end of the modular cable
into the telephone outlet.
2 For a SILC S/T interface with an optional auxiliary power source,
plug the power source into the wall outlet and then the 10-m (33-ft)
modular cable into the power source's RJ-45 type jack.
The power source must not feed the power back into the DSL through the
RJ-45 wall outlet, only to the local ISDN BRI terminal. The power
adapter is normally supplied with the terminal.
Figure 36 illustrates an ISDN BRI terminal connection to an S/T
interface. Figure 37 illustrates an ISDN BRI terminal connection to a
U interface.
3 Enter the Static TEI at the terminal.
Note: Do not perform this step to assign Dynamic TEIs since they are
automatically assigned.
4 Enter the Service Profile ID number at the terminal.
For detailed information about this procedure, refer to the terminal user
guide.
5 Repeat steps 1 to 3 for each ISDN BRI terminal to be connected.
