Configuring Circuit Lines
A circuit line is the physical line that carries data, voice, Frame Relay, or ATM traffic between a BPX
node (or IGX node) and customer premises equipment. Each piece of customer premises equipment is
attached to a node through a circuit line.
You must first establish or "up" a card by using the upcd command, before you can "up" and configure
a circuit line on that card.

Use the cnfln to configure commands (the cnfcln command is obsolete). The switch software prompts
for the parameters appropriate for the card type it detects. For details on each circuit line command, see
the Cisco WAN Switching Command Reference. Note: Line commands are the same as "circuit line"
commands.
Table 19-1 shows the permissible card combinations for CPE-to-IGX lines.
