Cisco IOS Dial Technologies Configuration Guide
The following example enables asynchronous rotary line queueing:
line 1 2
rotary 1 queued
The following example enables asynchronous rotary line queueing using the round-robin algorithm:
line 1 2
rotary 1 queued round-robin
Dedicated Asynchronous Interface Configuration Example
The following example shows how to assign an IP address to an asynchronous interface and place the
line in dedicated network mode. Setting the stop bit to 1 is a performance enhancement.

Access Restriction on the Asynchronous Interface Example
The following example shows how to allow most terminal users access to anything on the local network,
but restrict access to certain servers designated as asynchronous servers:
! access list for normal connections
access-list 1 permit 192.168.0.0 0.0.255.255
!
access-list 2 permit 192.168.42.55
access-list 2 permit 192.168.111.1
