Prerequisites
A 1-Port ADSL WIC must be installed in the router to match the DSL service to be configured.
Configuration Tasks
See the following sections for configuration tasks for this feature. Each task in the list is identified as
either required or optional:

Features used on the ADSL WAN interface card must also be configured on the DSLAM. See the
documentation for the specific DSLAM for information about configuring features.
Configuring the ADSL Port on the ADSL WAN Interface Card
To configure an ADSL port on the ADSL WAN interface card, complete the following steps:
Command
Step 1
Router> configure terminal
Step 2
Router(config)# interface
atm slot/port
Step 3
Router(config-if)# ip
address IP-address
Step 4
Router(config-if)# pvc
[name] vpi/vci
Step 5
Router(config-if-vc)#
protocol ip IP-address
Step 6
Router(config-if-vc)# vbr-rt

VoATM AAL2 and AAL5 are supported only if voice and data use separate permanent virtual
circuits (PVCs).
VoATM AAL2 supports digital voice (T1/E1) only, while VoATM AAL5 supports both analog and
digital voice.
VoIP is not supported unless the ADSL WIC carries only voice traffic (with no data). The QoS
features necessary for VoIP and data sharing the same PVC, or different PVCs on the same interface,
are not supported yet. These features include LLQ, LFI, and tx-ring tuning.

(optional)
Purpose
Enter global configuration mode.
Enter ATM configuration mode for the ATM interface in
the specified slot and port.
Assign an IP address to the ADSL ATM interface.
Entes atm-virtual-circuit (interface-atm-vc) configuration
mode, and configures a new ATM PVC by assigning a
name (optional) and virtual path identifier (VPI)/virtual
channel identifier (VCI) numbers.
The default traffic shaping is UBR; the default
encapsulation is AAL5+LLC/SNAP.
(Optional) Enable IP connectivity and create a
point-to-point IP address for the virtual circuit (VC).
(Optional) Configure the PVC for real-time variable bit
rate (VBR) traffic shaping.
peak rate—Peak information rate (PIR)
