VPI and VCI Numbers (with RFC 1483)
The VPI and VCI numbers apply to ATM routers only. Your router may have been preconfigured with
VPI/VCI numbers. If not, you will have to obtain these numbers from your Network Service Provider
and then configure them.
If you are connecting to multiple remote sites, you will need to obtain additional VPI and VCI numbers
from your Network Service Provider and/or Network Access Provider. These numbers identify the
remote destination and must, therefore, be unique for each remote.

DLCI (with RFC 1490)
The DLCI number applies to Frame-Relay routers only. Your Network Service Provider or your
Network Access Provider will provide you with a Data Link Connection Identifier (DLCI). The DLCI is
an address identifying your connection.
