Implementing Dial Services
10-4 Configuring Dialer Services
Implementing Dial Services
Dial services are provided by dialer interfaces, which are defined as any
XSR interface capable of placing or receiving a call. You can implement Dial Services by creating a
dialer profile.
Refer to Figure 10-2 for a network perspective and Figure 10-3 for a logical view of Dial Services.
Figure 10-2 illustrates a sample Dialer Profile which defines interface dialers in five corporate
locations served by the XSR.

Dialer Profiles
Dialer profiles are comprised of virtual and physical interfaces which can be bound together
dynamically on a per-call basis. Dialer profiles can also be configured as physical interfaces
separate from the virtual configuration required to make a connection.
This flexibility permits different dialer profiles to share XSR Serial interfaces. Dialer profiles are
efficient when physical resources number less than users because a pool of resources can draw on
the resources in the pool based on typical use. Be aware that all calls going to or from the same
destination subnetwork use the same dialer profile.
A dialer profile consists of the following elements:
• Dialer interface is a virtual WAN interface you can configure with data that defines
communications with destination sub-networks. The dialer interface is not constantly
connected to a remote device, but dials the remote device whenever a connection is needed—
on-demand. To dial up at the appropriate time requires configuring a dialer profile. It is
configured with the
interface dialer command. The dialer interface is spoofed by default
