What is ACC Business PNT?

Private Network Transport MPLS-enabled, Network-based, IP-VPN

serviceBased on a foundation of standard MIS

access portsProvides “Fully-Meshed” connectivity

between multiple customer defined locationsA closed private network exclusively using

the AT&T IP network for transport connectivity

PNT does not provide for Internet Access Parallel MIS port required at one or more locations

Traffic Class Distinctions

Four traffic service classes are available CoS 1 - Real-Time; targeted to applications

such as Voice over IP and video conferencing. CoS 2 - Critical Data; targeted to mission

critical data applications such as credit transactions and Enterprise Resource Planning (e.g. - PeopleSoft and SAP)

CoS 3 - Standard Business Data; targeted to applications such as Human Resource web sites, company email, etc.

CoS 4 - General Data Applications; targeted to general Internet browsing, FTP, etc

10

Customer Application Profiles

A “CoS Profile” is a template that is used within the network to allocate bandwidth across the Committed Data Rate (CDR) ordered by the customer CDR is the bandwidth equivalent of the MIS

port at each customer network location Each customer port will be provisioned

using one of 25 CoS profiles, each of which provide pre-determined bandwidth percentage allocations for each service class Assigned profile can be adjusted as evolving

customer application requirements may dictate
