1 BellSouth Long Distance, Inc. Original Page 1 Effective February 11, 2010 Domestic Asynchronous Transfer Mode (ATM) Service will no longer be available to new Customers. Existing Customers may maintain their existing service(s) under their BellSouth Business Class Family of Services agreement or Customized Pricing Arrangement (collectively the "Agreement") and continue to conduct moves, additions and administrative changes as needed, until their Agreement expires subject to the terms of the Agreement. Existing Customers may extend their current Agreement past its term for twelve (12) months, provided the 12 month extension is signed on or before June 30, Renewals of expired agreements will not be permitted after June 30, At the expiration of the current or extended term, Customers may continue to maintain their existing service on a monthly basis subject to the terms and conditions of this Pricing Guide or migrate to a comparable service offered by another long distance affiliate of the Company. 6.1 Service Description BellSouth Long Distance ATM service is a high-speed, connection oriented multiplexing and switching service that uses fixed-length cells to support transmission of multiple types of traffic (such as data, voice and video) over a Local Area Network (LAN) or Wide Area Network (WAN). Long Distance ATM service allows for a fixed-length 53-byte cell (48-byte payload and 5-byte header) to transport user data across the network. Switching is done based on the contents of the cell header. Provision of Long Distance ATM service and local access connectivity is subject to the availability of facilities. This service is available in all 50 states, Puerto Rico and U.S. Virgin Islands BellSouth Long Distance ATM Service components: (A) Customer Premises Equipment (CPE) Customer is solely responsible for all aspects of CPE, including, without limitation, the purchase, installation, and maintenance of CPE. Upon request, the Company will assist the Customer in obtaining the necessary CPE and CPE support. For Customers requiring CPE and/or CPE support, such services shall be provided pursuant to a separate written agreement. CPE information, terms and conditions are not contained in this Pricing Guide. (B) Dedicated Access A Dedicated Access channel provides the physical connection between the Customer s premises and the Company's ATM network. The speed of the Dedicated Access channel determines the BellSouth Long Distance ATM service access rate. Customers shall pay access and other interconnection charges (as set forth in Section 7 of this Pricing Guide) for connectivity from the Customer s premises to the nearest available Company Point of Presence (POP). As an alternative to local channels provided by the Company, the Customer may provide its own local channels or obtain such channels from an alternative access vendor (i.e. "Customer Provided Access"). Such interconnection of Company provided services with Customer Provided Access facilities is described in Section 7.1 of this pricing guide.

2 BellSouth Long Distance, Inc. Original Page Service Description (continued) BellSouth Long Distance ATM Service components: (continued) (C) Port The ATM Port provides a gateway into the BellSouth Long Distance Domestic Interexchange ATM Network, as defined in Section 6.4.1, and allocates the network s available capacity to the Virtual Connections it supports. Long Distance ATM service supports four User Network Interface (UNI) Port speeds as defined below:.1 DS - 1 (up to Mbps).2 DS - 3 (up to Mbps).3 OC - 3 (up to Mbps).4 OC - 12 (up to Mbps) (The OC - 12 UNI Port is available on an Individual Case Basis only.) At least one Port must exist for each customer premises directly connected to the BellSouth Long Distance Domestic Interexchange ATM Network. (D) Virtual Connections Virtual Connections are two-way, software-defined data paths between two Ports that act as replacements for private or dedicated leased lines in the Customer s network. BellSouth Long Distance ATM service supports cell routing on a pre-established connection or Permanent Virtual Circuit (PVC). ATM logical connections have a twolayered hierarchical addressing scheme: virtual channels (VCs) and virtual paths (VPs). A VC is the lowest order logical address in ATM. It refers to a specific circuit on an ATM link. A VP is the highest order logical address and refers to a given group of channels on a link. Customers have the option of choosing whether they want VC or VP connections. Customers may select desired committed cell rates in increments of 8 Kbps Duplex for each PVC. Depending on the ATM service category selected by the Customer, Long Distance ATM service may support Port oversubscription. In no event can the Peak Cell Rate of a particular VC exceed the Port Connection speed of either Port it is assigned to in the ATM network. The Customer will pay a monthly charge for based on the Quality of Service and associated Usage Parameters selected by the Customer.

3 BellSouth Long Distance, Inc. Original Page Usage Parameters The following Usage Parameters for traffic control and congestion control apply to particular Virtual Connections on the BellSouth Long Distance Domestic Interexchange ATM Network: Peak Cell Rate (PCR) - The maximum instantaneous rate (in Kbps or cells per second) that a source will transmit on a particular Virtual Connection. Sustained Cell Rate (SCR) - The average rate (evaluated in Kbps or cells per second over Sample Periods in one calendar month) that a source would transmit on a Virtual Connection. Maximum Burst Size (MBS) - The maximum number of back-to-back cells that a source can transmit over a particular Virtual Connection at the PCR. Minimum Cell Rate (MCR) - The minimum cell rate designated by a Customer on a particular Virtual Connection. 6.3 Quality of Service Parameters for Virtual Circuits Permanent Virtual Circuits Five Quality of Service parameters are available for BellSouth Long Distance ATM service PVCs. These parameters are available individually for each connection. The available parameters are as follows: Constant Bit Rate (CBR) - The CBR service layer provides a fixed amount of bandwidth for a Peak Cell Rate that is continuously available during the service connection term. The CBR can support applications with a tightly constrained Cell Transfer Delay (CTD) and Cell Delay Variation (CDV) and a low Cell Loss Ratio (CLR). Variable Bit Rate - Real Time (VBR-rt) - The VBR-rt service layer provides a sustained data rate (in Kbps or cells per second) with a guaranteed burst rate (in Kbps or cells per second) for occasional use at peak transmission periods (bursty applications). The VBR-rt can support applications with a tightly constrained CTD and CDV and a low CLR. The Usage Parameters are PCR, SCR (where PCR=SCR) and MBS. PVCs are priced at Kbps of the PCR or the SCR. Variable Bit Rate - Non-Real Time (VBR-nrt) - The VBR-nrt service layer provides a sustained data rate (measured in Kbps or cells per second) with a guaranteed burst rate (measured in Kbps or cells per second) for occasional use at peak transmission periods (for bursty traffic without tight parameters on CDV). The VBR-nrt can support applications with a tightly constrained CTD and a low CLR. The Usage Parameters are PCR, SCR and MBS. PVCs are priced based on the Kbps of SCR. Available Bit Rate (ABR) - The ABR service layer provides a guaranteed minimum capacity or MCR available on a VC with the ability to burst above the minimum capacity with low CLR when network capacity is available. ABR is not intended to support non-real time applications. CDV is not controlled in this service, however, higher efficiency is enabled by providing feedback on network congestion information allowing for the control of the source rate. The Usage Parameters are MCR and PCR.

4 BellSouth Long Distance, Inc. Original Page Quality of Service Parameters for Virtual Circuits (continued) Permanent Virtual Circuits (continued) Unspecified Bit Rate (UBR) - The UBR service layer provides capacity only as it is available on the network. No guarantees on minimum capacity or MCR are defined and the BellSouth Long Distance Domestic Interexchange ATM Network makes no performance commitment. All cells are eligible to be discarded by the BellSouth Long Distance Domestic Interexchange ATM Network. UBR is intended for applications that do not require specified bit rate or timing synchronization between source and destination or applications that utilize a higher layer protocol for this function. A UBR PVC is priced at the Kbps of the PCR Frame Relay Service to ATM Service Interworking Frame Relay service to ATM service interworking is supported by BellSouth Long Distance ATM service. The Interworking function will allow for the connection of Frame PVCs to ATM host circuits. This function will be made available to customers at no extra charge. This function is performed through the Frame Relay Forum FRF.8 specifications. 6.4 Service Assurance Guarantee Definitions The following definitions apply to Section 6 of this Pricing Guide only: BellSouth Long Distance Domestic Interexchange ATM Relay Network - the ATM network located in those areas of the United States Mainland, Hawaii and U.S. Virgin Islands comprise only of BellSouth Long Distance On-Net Facilities.
