Configuring Dialer Services
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 subnetworks. The
dialer interface is not constantly connected to a remote device, but
dials the remote device whenever a connection is needed. To dial up
at the appropriate time requires configuring a dialer profile. It is
configured with the
interface dialer command.
 Dialer map class defines all line characteristics of calls to the
destination including the interval to wait for a dial signal. It is
specified with the
map class dialer command.
 IP address identifies the local side of the connection. It is configured
with the
ip address command.
 Dialer strings are phone numbers used to reach a destination. They are
set with the
dialer string command.
 Dialer pool is a virtual group of physical interfaces used to reach a
destination. Interfaces in a dialer pool are weighted by priority. It is
configured with the
dialer pool command.
Dialer Interface
A dialer interface, which is a group of settings used by the XSR to connect to a
remote network, can include multiple dial strings. Each dial string, in turn,
can be associated with its own map class which defines all the characteristics
for any call to the specified dial string. Refer to dialer profiles of interface
dialer 0 which are illustrated in Figure 22 and Figure 23.
