When You Use It
To make a voice connection, the router must have a supported VIC
installed. The router supports up to three cards. You can either order
the cards when ordering the router, and they will be installed for
you, or you can order the cards separately, after receiving the router,
and install them yourself.
This cable connects the router to the Ethernet LAN and the WICs to
various WAN services, including ISDN, T1/FT1, and 56-kbps
services. You will need one cable for each of these connections.
This cable connects the VIC to a telephone, fax machine, or a
telephone wall-jack. You will need one cable for each of these
connections.
This cable connects the VIC to a PBX trunk line. You will need one
cable for each of these connections.
This cable connects a serial card to serial services. You must order
this cable from Cisco. For detailed information about serial cable
types, refer to the Cisco WAN Interface Cards Hardware
Installation Guide that comes with every card.
Some ISDN service providers require a Network Termination 1
device to connect an ISDN S/T port to the ISDN line.
To configure the router from a remote location, connect a modem to
the AUX port on the router.
