Implementing Dial 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 10-2for a network perspective and Figure 10-3for a logical view of Dial Services.

Figure 10-2illustrates 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
