The Cisco Wholesale Dial outsourcing solution delivers “virtual port” capability across any number of Cisco remote-access servers.

Coupled with third-party port policy management that guarantees port availability to wholesale customers, Cisco helps carriers and ISPs

offer unique service offerings that increase incremental revenue while keeping operations costs low. The network infrastructure deployed

for wholesale dialup also can be used to offer standard retail dialup services, plus other value-added services such as corporate dial

outsourcing, Internet gaming, unified communications, VoIP, and VPNs.

Regional and Branch-Office Connectivity

The Cisco AS5400XM Universal Gateway is ideally suited for deployment in branch offices for providing remote access for telecommuters

and mobile users. The CT1, CE1, and PRI interfaces can be used for remote access; the Ethernet ports can be used for LAN connectivity;

and the serial ports can be used for access to the corporate site or to the Internet. Using the Enterprise Plus features of Cisco IOS Software,

desktop protocols can be enabled.

Access VPNs

The Cisco AS5400XM Universal Gateway is ideally suited to providing wholesale dial services to both large corporations and ISPs that do

not want to support their own dial pools. With Cisco IOS Software support for VPNs, service providers can take advantage of their existing

infrastructures to deliver local dialup access for users of enterprise networks. By providing virtual dialup solutions, service providers can

offer a full range of services closer to the remote user. Local calls can now be placed to gain access to the core infrastructures. Virtual

dialup services attract more users of this service, and because calls are terminated locally, long-distance charges are eliminated and

infrastructure costs are reduced.

VPN Provisioning and Accounting

Of importance to service providers in the VPN environment is the need to both provision and account for the number of connections that

are allowed by VPN customers. Cisco Virtual Private Dialup Network (VPDN) session-counting software can keep track of the number of

connections from the Cisco AS5400XM Universal Gateway to the user’s home gateway. This software is provided in Cisco IOS Software

running on the Cisco AS5400XM and in the Cisco Access Control Server to provide comprehensive accounting and billing information to

ISPs about the virtual connections that their customers make.

AOL Support

The Cisco AS5400XM Universal Gateway offers 100-percent coverage for dedicated AOL dial installations, as well as other services that

use the TCP Clear or autocommand Telnet method of carrying dialup data. DNS round robin also is supported to allow load balancing of

connections across multiple AOL hosts. The Cisco AS5400XM also includes all the L2TP features necessary to support clients with AOL

7.0 and later versions.

Manageability

The Cisco AS5400XM offers a wide range of open protocols to support management. The Simple Network Management Protocol (SNMP)

Versions 2 and 3 management capability includes a rich call-tracking SNMP MIB that provides highly detailed records for active and

historical calls, with a configurable call-history buffer. Call records also can be obtained through syslog or RADIUS as an alternative to

polling through SNMP. Call records include connect rate, connect duration, disconnect codes, end-to-end delay, and line statistics. Voice

and dial service providers can use this performance-management data to establish service-level agreements with their customers.

The console-management features include a comprehensive set of debugging commands than can be enabled on a specific calling line ID

(CLID) or ANI, called number (DNIS), user, or interface to immediately isolate only the relevant debugging output.

CiscoWorks includes a plug-in to manage the Cisco AS5400XM Universal Gateway.
