Connecting the 2-Port ISDN BRI Card

Use the straight-through RJ-45 cable to connect the 2-port ISDN BRI card to the ISDN network through a telephone wall outlet.

Caution To prevent damage to the router, be sure to connect the BRI cable to the BRI connector only and not to any other RJ-45 connector.

Step 1	Confirm that the router is still turned off.
Step 2	Connect one end of a straight-through RJ-45-to-RJ-45 cable to the card’s RJ-45 port. (See Figure 7.)
