B7.4 LightGate Service (Cont'd)B7.4.2 Application of Rates (Cont'd)

I . LightGate service rates under contract will not be increased by Company initiative until the contract period expires. Thosemonthly rates for LightGate service in effect at the time the service is installed and/or as of the service order application date,will be applicable until the contract expires. At the expiration date of the customer's payment period option, the customer mayselect a new payment period option at current contract rates or revert to current rates on a month-to-month basis. If thecustomer does not select a new payment period or does not request discontinuance of service, service will be continued underthe terms specified in B2.4 of this Tariff.

J. A Termination Liability Charge is applicable at the date of termination. The applicable charge is dependent on the contractperiod subscribed to and will be equal to the number of months remaining in the contract times fifty percent (50%) of themonthly rates for the LightGate service rates which are provided under contract, and are subject to the exemptions of 1.and 2.following.

1. No Termination Liability Charge will be applicable for the LightGate service System when the customer renegotiates anew contract for the same system at the same location(s) for a period of time greater than the time remaining on theexisting contract, subject to contract periods contained in J. preceding.

2. Termination Liability charges do not apply to Channel Interfaces under the Channel Services Payment Plan.

K. Transfer of service responsibility between customers is permitted subject to payment of a Transfer Charge as determined on anindividual case basis.

B7.4.3 Digital Architecture and DefinitionsA. Digital Architecture

1. LightGate services differ in provisioning method and numbering format from single channel services. These services willbe available from the Company on a link (partial channel) basis rather than as an end-to-end service. This architecture isintended to promote more efficient connectivity of analog and digital networks in the future.

Many LightGate service channels will be available on a digital basis at the network interface on a customer's premises.Traditional analog services, like tie lines, off-premises stations, and PBX trunks can be provided on a digital basis to acustomer's premises by the Company when a customer desires them encoded in a DS1 bit stream. Under thoseconditions, they will be provided as DS0 channels by the Company. Both the Company and the customer have jointresponsibilities to ensure the proper transmission of the provided services. Normal analog channel network interfacespecifications will be superceded by the electrical specifications of the 1.544 Mbps (DS1) channel which is actuallyterminated. Each DS0 channel provided will have identity only as a "time slot" within a DS1 channel. Compatible digitalto analog conversion equipment must be provided by the customer to derive the desired analog services. Any ChannelService Units (CSUs) necessary for digital services are the responsibility of the customer.

B. Definitions

CHANNEL SERVICE UNIT (CSU)The term CSU denotes network channel terminating equipment provided by the customer to terminate digital channel facilitieson a customer's or user's premises.

DS0The term DS0 denotes a channel service expressed in terms of its digitally encoded data bit rate in accordance with the NorthAmerican hierarchy of digital signal levels. It is generally referred to as having a 64 Kbps transmission bit rate signal. Therequired format and interface specifications are referenced in BellSouth Technical Reference 73501.

DS1The term DS1 denotes a channel service expressed in terms of its digitally encoded bit rate in accordance with the NorthAmerican hierarchy of digital signal levels. It has a 1.544 Mbps transmission data rate, and provides for the two-waysimultaneous transmission of isochronous timed, Bipolar Return-to-Zero (BPRZ) bit stream format, except where intentionalbipolar violations are introduced by Bipolar with 8 Zero Substitution (B8ZS) format. Unframed signal formats are notpermitted or compatible with Company equipment. The required format and interface specifications are contained in BellSouthTechnical Reference 73501.

B7.7.1 General (Cont'd)L. Effective December 6, 2006, Shared Node Interconnection capability is available whereby two SMARTRing service

arrangements belonging to the same customer may share a node in a central office that is common to both rings. Shared NodeInterconnection capability is available based on equipment capability. With Shared Node Interconnection, one of the rings(i.e., the larger capacity ring) is considered the Primary Ring and the other ring is considered the Secondary Ring. PrimaryRings may be an OC-12, OC-48 or an OC-192 ring. A Secondary Ring is always a lower capacity ring than that of thePrimary Ring. The various Shared Node Interconnection service arrangements that are available are as follows:

Shared Node InterconnectionPrimary Ring Capacity

Shared Node Interconnection

Secondary Ring Capacity Available For Use With Primary RingsOC-3 OC-12 OC-48 OC-48+

OC-12 X

OC-48 X X

OC-192 X X X X

With Shared Node Interconnection, the Primary Ring shall have a Central Office Node and the Secondary Ring shall have aShared Node Interconnection Central Office Node in the central office associated with the ring interconnection. For theSecondary Ring, a Shared Node Interconnection Central Office Node is considered toward meeting the three node minimumrequirement for the Secondary Ring. This shared node will utilize capacity of the Primary Ring node, based on the size of theSecondary Ring, and will count toward the capacity the customer has available at the location. Should the customer requiremore capacity at a shared node central office location than is available on the Primary Ring node, then additional billableservice components will be required.

Only one Shared Node Interconnection arrangement is available for an individual Central Office Node on a Primary Ring.

Reconfiguration is not allowed at central office nodes that are configured for Shared Node Interconnection.

B7.7.2 Application of Rates (Cont'd)C. SMARTRing service OC-3, OC-12, or OC-48 channel interfaces are associated with optical circuits within a SMARTRing

service arrangement. These optical circuits may be provisioned as concatenated. When an optical circuit is provisioned asconcatenated, the multiple STS-1s within the optical circuit are provided as a single entity with a single overhead channel.When an optical circuit is provisioned as concatenated at the time the circuit is installed, there is no additional charge forprovisioning it as concatenated. When an existing non-concatenated optical circuit is requested to be reconfigured asconcatenated, a concatenation rearrangement charge shall apply. This rearrangement charge shall also apply for existingconcatenated circuits that are requested to be converted to non-concatenated.

D. SMARTRing service interfaces may be ordered as asymmetrical (i.e., a circuit enters one node at a lower level interface andexits at another node at a higher level interface). For example, a customer may have a service that connects to a ring via anOC-3 interface at a node. That service is then transported around the ring and connects via an OC-12 interface to another ofthe customer’s services. The allowable asymmetrical interface arrangements for the various ring sizes are as shown inTechnical Reference TR-73582. The interface rates for asymmetrical arrangements are the same as the rates for symmetricalarrangements except as follows:

For lower level DS1 interfaces in an asymmetrical arrangement with an STS-1 interface, the DS1 within an STS-1Asymmetrical Arrangement interface rate element applies in lieu of the STS-1 interface for the higher level termination.

For lower level DS1 interfaces in an asymmetrical arrangement with a DS3 interface, the DS3 (Asymmetrical with DS1)interface rate element applies in lieu of the DS3 interface for the higher level termination of the asymmetrical arrangement.

E. In addition, customers with DS3 interfaces at the Customer Node electing to connect with DS1 services at a Central OfficeNode, must obtain a 28 DS1 Channel System, and the appropriate number of DS1 Channel Interfaces. The applicable rateelements for this arrangement are a DS3 Interface at the Customer Node and a 28 DS1 Channel System with DS1 Interfaces atthe Central Office Node. The SMARTRing service 28 DS1 Channel System does not require a DS3 interface at the CentralOffice Node. A maximum of 28 DS1 Channel Interfaces can be activated for each 28 DS1 System utilized. Nonrecurringcharges are established on a per order basis for each 28 DS1 Channel System and for each additional 28 DS1 Channel Systemat that same Central Office Node. Nonrecurring charges apply for each DS1 Channel Interface which originates/terminates in a28 DS1 Channel System. The recurring rate applies for each 28 Channel System and each DS1 Channel Interface activated perCentral Office Node.

F. In order to accommodate more flexible customer situations, SMARTRing service is available under several payment plans: 36Month Term Payment Plan (24-48 months), 60 Month Term Payment Plan (49-72 months), or 84 Month Term Payment Plan(73-96 months). The 36, 60, and 84 Month Term Payment Plans are provided under conditions specified in the ChannelServices Payment Plan, (CSPP), B2.4.9 preceding, except as modified following. For all payment plans, the followingregulations apply:

1. All rate elements, except Channel Interfaces for a given SMARTRing service, whether initially or subsequently ordered,must be provided under the same payment plan with the same service period and are coterminous upon disconnect of theSMARTRing service. Channel Interfaces may be ordered under payment plans equal to or less than the selected paymentperiod for the given SMARTRing service.

2. The rates applicable to a month-to-month payment plan are subject to Company initiated changes.

3. A termination liability charge will be applicable if services provided under a CSPP arrangement are disconnected prior tothe end of the chosen service period. The applicable charge is equal to the number of months remaining in the ratestabilized service period times fifty percent (50%) of the monthly rates for SMARTRing service which include allNodes, Local Channels, Alternate Central Office Channels, Internodal Channels and/or Interoffice Channels providedunder the CSPP arrangement. For services under the month-to-month payment plan, a termination charge is equal to thenumber of months remaining in the twelve month minimum times the month-to-month rates in effect for SMARTRingservice at the time of termination.

4. When a service period under an existing CSPP arrangement is completed and a customer elects to revert to amonth-to-month payment option, no minimum period is applicable. If the customer does not select a new payment periodor does not request discontinuance of service, service will be continued under the terms specified in B2.4 of this Tariff.

5. Additions of services or rate elements, for activating spare or unused capacities of a SMARTRing service under a CSPParrangement, must be activated at the same rates and charges specified under the existing CSPP arrangement. Channelinterfaces may be ordered as specified in 1. preceding.

6. Additions of services or rate elements, i.e. new local channels, interoffice channels, etc., other than for activating spare orunused capacities, must be under a new CSPP arrangement at rates and charges as specified in 1. preceding. The newCSPP arrangement must be at least 24 months and must be coterminous with the CSPP arrangement for the existingSMARTRing service.

7. All customers ordering a new SMARTRing service or upgrading existing SMARTRing service under a Channel ServicesPayment Plan (CSPP) by February 13, 1996, with a Service Establishment Date of no later than May 21, 1996, willbenefit from a special promotional offering to waive nonrecurring charges associated with ring level billing.

All SMARTRing service customers under a Special Service Arrangement contract, where the service has not beeninstalled as of October 13, 1995, will benefit from the special promotional offering to waive nonrecurring chargesassociated with ring level billing.

Ring level billing is defined as billing for the following rate elements: Local Channel, Interoffice Channel, InternodalChannel, Alternate Central Office Channel, Customer Node and Central Office Node. Billing for Customer ChannelInterfaces and Central Office Channel Interfaces recurring and nonrecurring charges will be effective upon activation tothe SMARTRing service.

In addition, termination liability charges are also waived for upgrades to SMARTRing services, under the terms andconditions set forth in B2.4.9 preceding. Specific requirements must be satisfied in order for charges to be waived asfollows:

a. Nonrecurring charges set forth in B3.3 of this Tariff will be waived when a customer reconfigures existing Companyprovided network services that are groomed or rolled over onto a new SMARTRing service or upgraded fromexisting SMARTRing service.

b. The customer's SMARTRing service, to which the network services are reconfigured, must be ordered under aCSPP. However, individual DS1 and/or DS3 channel interfaces associated with SMARTRing service may beprovided under month-to-month terms if the existing services were provided under month-to-month rates.

c. Special promotional waivers will be processed as projects for each customer designated location, and all associatedconnect and disconnect orders must be placed at the same time. Reconfiguration work must be completed withintwelve months of the customer order date. Only one reconfiguration plan will be permitted per customer location.

d. Special promotional waivers shall not apply when the service is moved by the customer from one location to another.

e. In the event the SMARTRing service is disconnected at the customer's request prior to the expiration of the CSPP,full nonrecurring charges associated with ring level billing will apply.

B7.7.2 Application of Rates (Cont'd)K . For conversions of LightGate service to a higher capacity OC-12, OC-48, OC-48+, OC-192 or OC-192+ SMARTRing service

and for conversions of SMARTRing service to a higher capacity SMARTRing service arrangement, customers will be allowedto defer the start of SMARTRing service ring level billing when the new service arrangement is provided under the ChannelServices Payment Plan (CSPP), as described in B2.4.9, preceding. The period of deferred billing shall be based on theTelephone Company’s estimation of the time required for conversion, up to a maximum of 60 days. This applies to orders fornew service associated with conversions, as described above, or orders associated with a project for conversion that is pendingcompletion, as of September 22, 2006. For orders associated with a project for conversion that is pending completion, thedeferred start of ring level billing shall be accomplished via credits to the customer’s bill. For upgrades, as described above,that are completed in less than 60 days, the deferred start of ring level billing shall be associated with the completion of theupgrade. Customer’s SMARTRing service CSPP arrangements shall begin after the deferral period and continue tocompletion, as described in B2.4.9, preceding, for the customers selected CSPP commitment period.

Ring level billing is defined as billing for the following rate elements: Local Channel, Interoffice Channel, Internodal ChannelAlternate Central Office Channel, Customer Node and Central Office Node. Billing for Customer Channel Interfaces andCentral Office Channel Interfaces recurring will be effective upon activation of the interface and is not available for deferredbilling.

In case of a service outage associated with SMARTRing service ring level rate elements that have deferred billing, asdescribed above, for new service associated with conversions or service associated with a project for conversion that ispending completion, a service outage credit will not apply.

L. For situations where a customer requests Local Channel and Interoffice Channel service components to a central office andalternate facilities are available that provide an equal or higher level of protection than the requested service arrangement, suchalternate facilities may by utilized, with concurrence of the customer, and the rate application shall be that of the Local Channeland Interoffice Channel service components as requested by the customer.

M. Shared Node Interconnection Central Office Node charges apply for each location on a Shared Node InterconnectionSecondary Ring involved in a Shared Node Interconnection arrangement. SMARTRing service Local Channel, InterofficeChannel, etc., ring level service components apply to the Shared Node Interconnection Central Office Node in the samemanner as associated with a Central Office Node.

The credit for service outages associated with Shared Node Interconnection Central Office Nodes shall be the same as isapplicable to ring level nodes.

Should the customer require more capacity at a shared node central office location than is available on the Primary Ring node,then additional billable service components will be required.

B7.7.3 Architecture (Cont’d)A. SMARTRing Service (Cont’d)

- SMARTRing service - When the distance between nodes on a SMARTRing service (a.k.a. BellSouth SPA DedicatedRing) is such that optical signal regeneration is required, then regeneration equipment will be provided at no additionalcharge to the customer to assure proper operation of the service. Accordingly, FlexServ service Customer NetworkManagement may not be ordered with a Regeneration Node, however, a customer may monitor a Regeneration Node viathe FlexServ service Customer Network Management Surveillance option when a customer has established surveillancefor a ring. Regeneration Node Surveillance is provided as a part of the charges associated with the customer’s ring levelFlexServ service Customer Network Management Surveillance. A Regeneration Node and Regeneration NodeSurveillance, as applicable, will appear on a customer’s records as a non-rated USOC, as follows:

USOCRegeneration Node, all ring capacities, non-rated SHNRDRegeneration Node Surveillance, all ring capacities, non-rated SHNRS

- SMARTRing service Virtual Packet Rings may be established to work with either electrical or optical Basic SharedEthernet LAN Access Links. A Virtual Packet Ring established associated with electrical access links will only workwith electrical Basic Shared Ethernet LAN Access Links and a Virtual Packet Ring established associated with opticalaccess links will only work with optical Basic Shared Ethernet LAN Access Links. Electrical and optical access linksmay not be mixed on the same Virtual Packet Ring.

- An individual Basic Shared Ethernet LAN Access Link associated with a VPR may not be equal to the size of the VPRand the sum of all or access links on a VPR must be equal to or less than the size (i.e., capacity) of the Virtual PacketRing. An individual SMARTRing service arrangement may have multiple Virtual Packet Rings, up to and including thecapacity of the ring.

- Customer requested upgrades of SMARTRing service will involve a service outage associated with Basic SharedEthernet LAN Access Links, for which a credit for service outage shall not apply.

- Shared Node Interconnection (SNI) is available, based on equipment capability, whereby two SMARTRing servicearrangements belonging to the same customer may share a node in a central office that is common to both rings.
