On ADSL WAN interfaces, the ATM connection between the router and the central office equipment (DSLAM) is
divided logically into one or more virtual circuits (VCs). A virtual circuit may be either a permanent virtual circuit
(PVC) or a switched virtual circuit (SVC). Netopia Routers support PVCs.
VCs are identified by a Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI). A VPI is an 8-bit value
between 0 and 255, inclusive, while a VCI is a 16-bit value between 0 and 65535, inclusive.
The Netopia R6000 Series supports up to eight PVCs on these interfaces.
Circuits support attributes in addition to their VPI and VCI values. When configuring a circuit, you can
specify an optional circuit name of up to 14 characters. The circuit name is used only to identify the circuit
for management purposes as a convenience to aid in selecting circuits from lists. The default circuit name
is "Circuit <n>", where <n> is some number between one and eight corresponding to the circuit's position
in the list of up to eight circuits.
You can also individually enable or disable a circuit without deleting it. This is useful for temporarily
removing a circuit without losing the configured attributes.
In order to function, each circuit must be bound to a Connection Profile or to the Default Profile. Among
other attributes, the profile binding specifies the IP addressing information for use on the circuit. Each
circuit must be bound to a distinct Connection Profile. You cannot bind multiple circuits to the same
Connection Profile. Thus it is not possible to construct point-to-multipoint meshes with ATM as is possible
with Frame Relay.
Select Display/Change Circuit and press Return.
