Configuring Dial Services

1-6

In Figure 1-3, three circuits share two physical lines that make up Demand Pool 1.

Note that only two of the circuits using Demand Pool 1 can be active

simultaneously because only two modems are available. The IP addresses are

associated with each circuit, not with the physical line.

Activating Demand Circuits

The router activates a demand circuit under one of three conditions:

• The router has data to send across the circuit.

When the router has data to transmit, it automatically selects one of the

demand lines from the circuit’s associated demand pool. As long as data is

going across the line, the end-to-end connection remains active.

• You specify a time of day to activate the circuit.

Using the Schedule option, you can schedule the circuit’s availability for a

speciﬁc day and time. The schedule parameters are part of the circuit’s

conﬁguration (refer to Chapter 5). The Schedule option also allows you to

conﬁgure whether the router uses the Inactivity Time parameter to

dynamically bring down the connection.

• You enable a force dial. The router forces the establishment of a connection.

To activate a line immediately, you conﬁgure the Force Dial parameter. Using

this parameter, you can force the connection to come up regardless of whether

there is data activity. To learn how to conﬁgure this parameter, turn to

Chapter 5.

Adding Bandwidth for Demand Lines

To provide more bandwidth for a congested demand line, you can use up to three

additional lines from an existing bandwidth-on-demand pool to aid the congested

demand line. This feature beneﬁts time-critical applications that rely on data

reaching its destination efﬁciently.

When trafﬁc becomes too heavy for a demand line, the router, conﬁgured as the

congestion monitor, can activate additional lines for more bandwidth. The router

uses lines from an existing bandwidth-on-demand pool. You associate this

bandwidth pool with a demand circuit. If trafﬁc over the demand line exceeds a

certain user-conﬁgured threshold, the router activates the additional lines.
