| In the previous chapter, you saw how
to configure call parameters under a physical interface. The following
are some commands required for setting up rotary groups.
The command
dialer string
is used to specify the phone number
to dial when placing a call from an interface to a specific destination.
A modem chat-script must be defined and used to implement dialing on
asynchronous interfaces. The syntax is as follows:
Router(config-if)#dialer string dial-string
dialer string and dialer group
Commands
If a
dialer string
command is specified without a
dialer group
command with access lists defined, dialing is never
initiated. If the
debug dialer
command is enabled, an error
message displays and indicates that dialing never will occur.
By default, packets are dropped during the time required to establish
a connection. To prevent this, use the
dialer hold-queue
command,
which allows interesting outgoing packets to be held in a queue while
dialing takes place. The number of packets allowed in a queue ranges
from 0 to 100. The syntax is as follows:
Router(config-if)#dialer hold-queue
