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 dial 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 using resource pool management. With the implementation of the new voice command in resource-pool profile service configuration mode, a resource group with voice service is designated under a particular customer profile, and voice resource pool service is enabled after resouce pool management is configured.

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 over-subscription 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

•Authentication, authorization, and accounting (AAA)

•Point-to-Point Protocol (PPP)

•Virtual Private Dialup Network (VPDN)

Determining Platform Support Through Cisco Feature Navigator

Cisco IOS software is packaged in feature sets that support specific platforms. To get updated information regarding platform support for this feature, access Cisco Feature Navigator. Cisco Feature Navigator dynamically updates the list of supported platforms as new platform support is added for the feature.

Cisco Feature Navigator is a web-based tool that enables you to determine which Cisco IOS software images support a specific set of features and which features are supported in a specific Cisco IOS image. You can search by feature or release. Under the release section, you can compare releases side by side to display both the features unique to each software release and the features in common.

To access Cisco Feature Navigator, you must have an account on Cisco.com. If you have forgotten or lost your account information, send a blank e-mail to cco-locksmith@cisco.com. An automatic check will verify that your e-mail address is registered with Cisco.com. If the check is successful, account details with a new random password will be e-mailed to you. Qualified users can establish an account on Cisco.com by following the directions at http://www.cisco.com/register.

Cisco Feature Navigator is updated regularly when major Cisco IOS software releases and technology releases occur. For the most current information, go to the Cisco Feature Navigator home page at the following URL:

http://www.cisco.com/go/fn

Availability of Cisco IOS Software Images

Platform support for particular Cisco IOS software releases is dependent on the availability of the software images for those platforms. Software images for some platforms may be deferred, delayed, or changed without prior notice. For updated information about platform support and availability of software images for each Cisco IOS software release, refer to the online release notes or, if supported, Cisco Feature Navigator.

Supported Standards, MIBs, and RFCs

Standards

No new or modified standards are supported by this feature.

MIBs

No new or modified MIBs are supported by this feature.

To obtain lists of MIBs supported by platform and Cisco IOS release and to download MIB modules, go to the Cisco MIB website on Cisco.com at http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml.

RFCs

No new or modified RFCs are supported by this feature.

Prerequisites

Because Cisco RPM differentiates customers through configured customer profiles based on the DNIS and call type determined at the time of an incoming call, the following components of resouce pool management must be configured before enabling voice resource pool service:

•Customer Profile Types

•Call Types

•DNIS Groups

•Resource Groups

•Resource Services

For more information about configuring resouce pool management, see Configuring Resource Pool Management.

Configuration Tasks

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

•Confirming Voice Resource Pool Service Availability (optional)

•Enabling Voice Resource Pool Service (required)

•Verifying Voice Resource Pool Service (optional)

Confirming Voice Resource Pool Service Availability

To confirm voice resource pool service availability, use the following commands, beginning in global configuration mode:

 
Command

Step 1 

Router(config)# resource-pool profile service voip

Enters profile service configuration mode.

Step 2 

Router(config-service-profile)# ?
