These devices then assign IP addresses to the CPE and to a DHCP pool. The IPCP feature provides the following functions: The Cisco IOS CPE device requests and uses the subnet. The Authentication, Authorization, and Accounting (AAA) Remote Authentication Dial-In User Service (RADIUS) provides the subnet and inserts the framed route into the proper virtual route forwarding (VRF) table. The provider edge or the edge router helps in providing the subnet through IPCP. DHCP support is no longer on the client side because the CPE can now receive both the IP address and the subnet mask during the PPP setup negotiation. If the CPE uses the DHCP servers to allocate addresses for its own network, subnets can be assigned through the node route processor (NRP) on the network access server (NAS) and distributed to the remote CPE DHCP servers. Follow these steps to configure the Cisco router (CPE) for IPCP: Step 1Configure the ATM interface, and enter the ADSL operating mode. Step 2Configure the ATM subinterface. a.Create an ATM PVC for data traffic, enter virtual circuit configuration mode, and specify the VPI and VCI values. b.Set the encapsulation of the PVC as aal5mux ppp to support data traffic. Step 3Create a dialer interface. a.Enter configuration mode for the dialer interface. b.Specify the PPP encapsulation type for the PVC. c.Enter the ip unnumbered Ethernet 0 command to assign the Ethernet interface to the dialer interface. d.Configure the dialer group number. e.Configure CHAP. f.Enter the ppp ipcp mask request command. g.Assign a dialer list to this dialer interface. Step 4Define an IP DHCP pool name. a.Enter the import all command. b.Enter the origin ipcp command. Step 5Configure the Ethernet interface, and assign an IP address pool. Enter the pool name that you defined in Step 4. Step 6Configure a dialer list and a static route for the dialer interface.

The SA agent is a new name and an enhancement for the Response Time Reporter (RTR) feature
introduced in Cisco IOS Release 11.2.

Chapter 4 Advanced Router Configuration
Configuring International Phone Support
Use the following procedure to configure a voice port to support caller ID, international cadence,
impedance, and ring frequency, starting in global configuration mode:
Step 1Enter the voice-port number command to enter voice-port configuration mode.
Step 2Enter the cptone country-code command to specify settings for call-progress tone, ring cadence, line
impedance, and ring frequency.
Step 3Enter one of the following commands to enable caller ID:
Enter the caller-id enable command to enable caller ID support.
Enter the caller-id alerting alerting-method command to enable caller ID support and to specify the
alerting method.
Step 4Enter the caller-id block command to request blocking of the display of caller ID information at the far
end of the call.
Step 5Enter end to exit router configuration mode.
Configuration Example
The following voice-port configuration example shows two voice ports configured for the progress tone
and line characteristics for Denmark. Caller ID is enabled on both ports, and port 1 requests that caller
ID information be blocked at the other end when a phone call originates from this port. The second port
uses the line-reversal alerting method.

International Tone, Cadence, Ring Frequency, and Impedance Support
The default voice-port configuration for all voice ports specifies the U.S. country code, 600-ohm
impedance, and 25-Hz ring frequency. Cisco IOS software supports commands for setting ring tone,
cadence, frequency, and line impedance.
cptone Command
Use the voice-port configuration mode cptone command to specify a regional analog voice
interface-related tone. Use the no form of this command to disable the selected tone.
cptone { dk | it | au }
no cptone { dk | it | au }
