Feature History

Release	Description
12.2(2)XA	This feature was introduced on the Cisco AS5350 and Cisco AS5400.
12.2(2)XB	The Universal Port Resource Pooling for Voice And Data Services feature no longer needs to be enabled separately in resource pool management.
12.2(2)XB1	This feature was implemented on the Cisco AS5850 platform.

Feature Overview

With Cisco Resource Pool Manager (RPM), telephone companies and Internet service providers (ISPs) can share dial resources for wholesale and retail dial network services in a single network access server (NAS) or across multiple NAS stacks. Call management and call discrimination can be configured to occur before the call is answered, and customers are differentiated by using configurable customer profiles that are based on the Dialed Number Identification Service (DNIS) and call type determined at the time of an incoming call. As a result, Cisco RPM enables service providers to count, control, and manage resources and provide accounting for shared resources when implementing different service-level agreements.The Universal Port Resource Pooling for Voice and Data Services feature now enables service providers to mix voice and data services by designating speech as the supported call-type in the resource pool management customer profile.

Cisco RPM can be configured in one or more standalone Cisco NASs or, optionally, across multiple NAS stacks by using one or more external Cisco Resource Pool Manager servers (RPMSs). This document presents the single, standalone NAS version of Cisco  RPM. For more information about Cisco RPMS, see the Cisco Resource Pool Manager Server Solution Guide.

Benefits

The Universal Port Resource Pooling for Voice and Data Services feature provides the following benefits:

•Mix voice and data services in a single access server or stack of servers using resource pool management.

•Manage customer use of shared resources.

•Offer advanced wholesale dial-up services directly to customers. Because the PPP and AAA feature sets are selected by the incoming DNIS, the service provider no longer needs tunneling technology to provide unique service-level agreements to wholesale dial customers.

•Efficiently use resource groups to offer differing oversubscription rates and dial service-level agreements.

•Accept or reject a call based on the incoming DNIS number before answering the call.

•Include local retail dial services in the same NAS with the wholesale dial customers.

Restrictions

•For voice calls, resource pool management is done only for incoming calls, calls from PSTN legs. For outgoing voice calls, resources are allocated only from the default system resource group.

•Mixing of voice DNIS numbers and data DNIS numbers within the same DNIS group in resource pool management is not allowed.

•The same DNIS cannot be used for both voice and data calls in resource pool management.

•Modem pooling and resource pool management are not compatible.

Related Features and Technologies

•Point-to-Point Protocol (PPP)

•Virtual Private Dialup Network (VPDN)

Prerequisites

•Cisco IOS Release 12.2XB or later release

Because Cisco RPM differentiates customers through configured customer profiles, the following components of resouce pool management must be configured:

•Customer profile types

•Call types

---

Note For this feature, speech must be designated as the supported call-type using the resource command in customer profile configuration mode.

---

•DNIS groups

•Resource groups

•Resource services

Configuration Tasks

See the following sections for configuration tasks for this feature. Each task in the list is identified as either required or optional.

•Enabling RPM (required)

•Verifying RPM (optional)

Enabling RPM

To enable resource pooling for voice and data services, use the following commands, beginning in global configuration mode:

	Command	Purpose
Step 1	Router(config)# resource-pool enable	Enables RPM.

Verifying RPM

---

Step 1 Enter the show running-config command in privileged EXEC mode. If the "resource-pool enable" string is displayed, RPM is enabled.

Router# show running-config

...

resource-pool enable

!

resource-pool group resource voip-rg

 range port 3/1 3/15

!

resource-pool profile customer cp-voice

 limit base-size all

 limit overflow-size 0

 resource voip-rg speech service voip

 dnis group dnis-voip

...

---

Configuration Examples

This section provides the following configuration examples:

•Creating Resource Groups, Customer Profiles, and DNIS Groups Example

•Configuring DNIS Groups and Enabling RPM Example

Creating Resource Groups, Customer Profiles, and DNIS Groups Example

In the following example, resource group "voip-rg," customer profile "cp-voice," and DNIS group "dnis-voip" are created, and "speech" is designated as the supported call type:

Router(config)# resource-pool group resource voip-rg

Router(config-resource-group)# range port 3/1 3/15

Router(config-resource-group)# exit    

Router(config)# resource-pool profile customer cp-voice

Router(config-customer-profile)# limit base-size all

Router(config-customer-profile)# limit overflow-size 0

Router(config-customer-profile)# resource voip-rg speech

Router(config-customer-profile)# dnis group dnis-voip

Router(config-customer-profile)# exit

Configuring DNIS Groups and Enabling RPM Example

In the following example, DNIS is assigned with leading digits of 522, 525, and 526x to DNIS group "dnis-voip," and resource pool management is enabled:

Router(config)# dialer dnis group dnis-voip

Router(config-dnis-group)# number 522

Router(config-dnis-group)# number 525

Router(config-dnis-group)# number 526x

Router(config-dnis-group)# call-type cas speech

Router(config-dnis-group)# exit

Router(config)# resource-pool enable

Command Reference

There are no new or modified commands. All other commands used with this feature are documented in the Cisco IOS Release 12.2 command reference publications.

Glossary

AAA—authentication, authorization, and accounting.

DNIS—Dialed Number Identification Service. Telephone service that identifies for the receiver of a call the number that the caller dialed.

DSP—Digital Signal Processor.

NAS—network access server. Cisco platform or collection of platforms, such as an AccessPath system, that interfaces between the packet world (for example, the Internet) and the circuit world (for example, the PSTN).

PPP—Point-to-Point Protocol. Successor to SLIP that provides router-to-router and host-to-network connections over synchronous and asynchronous circuits. Whereas SLIP was designed to work with IP, PPP was designed to work with several network layer protocols and has built-in security mechanisms.

PSTN—Public Switched Telephone Network. General term referring to the variety of telephone networks and services in place worldwide.

RPM—Resource Pool Manager.

RPMS—Resource Pool Manager server.

SLIP—Serial Line Internet Protocol. Standard protocol for point-to-point serial connections using a variation of TCP/IP. Predecessor of PPP.
