Chapter 2 Installation
Installing Your Router
• If you are outside of North America, ask your telephone service provider if you must provide an
external Network Termination 1 (NT1) and the ISDN U cable that connects the NT1 to the ISDN
wall jack. Ask for NT1 vendors if necessary.
• If you are in North America, ask your telephone service provider for external NT1 vendors. Provide
the ISDN U cable that connects the NT1 to the ISDN wall jack.
Step 3 Be aware of Ethernet, ISDN, and IDSL cable distance limitations. For more information, see the
“Maximum Cable Distances” section in Appendix B, “Specifications and Cables.”
Step 4 Gather the Ethernet devices to be connected to the router: hub, server, workstation, or PC with 10- or
10/100-Mbps network interface card (NIC).
Step 5 If you have a Cisco 801 or Cisco 803 router and plan to connect a digital telephone, you must provide
an NT1 with two S/T interfaces and one U interface, a telephone cable to connect the telephone (usually
this cable is provided with the device), and an ISDN U cable that connects the NT1 to the ISDN wall
jack.
Step 6 If you have a Cisco 803 or Cisco 804 router, gather the devices (such as an analog telephone, fax
machine, or modem) that you plan on connecting to the router. You must also provide the telephone cable
to connect each device (usually this cable is provided with the device).
Step 7 If you plan to configure the software using a terminal or PC connected to the router, provide the terminal
or PC.
Step 8 If you plan to mount your router on a wall or vertical surface, you need to provide two number-six,
3/4-in. (M3.5 x 20 mm) screws. If the wall on which you mount your router is drywall, you instead need
to provide two hollow wall-anchors (1/8-in. with 5/16-in. drill bit or M3 with 8-mm drill bit) to secure
the screws.
Step 9 If you plan to use the cable lock feature, you need to provide a Kensington or equivalent locking cable.
