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

H. LightGate service Systems are available under contract only for variable rate periods with rates based on lengths of 24 to 48months, 49 to 72 months, or 73 to 96 months under conditions specified in B2.4 except as modified following. Contract rateincreases are subject to the stipulations of K. following. All elements of a contract will expire at the same time (becoterminous).

1. LightGate service Systems are available only under contract as specified preceding. Month to month rates are onlyavailable at the end of a contract rate period. Central office and customer channel interfaces are available on a month tomonth basis or under contract.

2. All rate elements associated with a LightGate service local channel or interoffice channel must be provided under thesame payment plan; provided however, that channel interfaces may be activated on month-to-month rates or a shorterpayment period if desired.

3. Channelized DS1/1.544 Mbps channels and Sub-DS1 Feature Activations are available under terms contained in theMegaLink channel service Tariff.

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 Termination Liability Charge for atariff term plan entered into prior to April 3, 2001, is dependent on the contract period subscribed to and will be equal to thenumber of months remaining in the contract times the monthly rates for the LightGate service rates which are provided undercontract, 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 LightGate service channel interface service components.

K . For tariffed term plans entered into on or after April 3, 2001, a customer's liability for the termination of service prior to thetime the customer's obligations under the tariff term plan would have otherwise been satisfied are set forth in B.2.4.9.A.4.preceding. For tariffed term plans entered into before April 3, 2001, the customer's obligations for the termination of serviceprior to the time the customer's obligations under the term plan would have otherwise been satisfied is governed by the termsof the tariff that were in effect as of the date the customer entered the tariffed term plan.

L. 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.

L. Shared Node Interconnection is available, based on equipment capability, whereby two SMARTRing service arrangementsbelonging 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 Rings

OC-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.

7. (Cont'd)

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.

I. SMARTRing service Local Channel, Alternate Central Office Channel and Internodal Channel rates are distance sensitive.They are measured per quarter airline mile or fraction thereof from the customer's designated premises to the Serving WireCenter, Alternate Central Office, or other Customer Nodes. V&H coordinates are derived for each customer location throughthe use of longitude and latitude measurements. Using the V&H coordinate method as set forth in the NATIONALEXCHANGE CARRIER ASSOCIATION, INC. TARIFF F.C.C. No. 4, compute the mileage, convert to quarter miles, andmultiply the appropriate per quarter mile rate by the distance involved. Any portion of a quarter mile will always round up tothe next quarter mile before determining the mileage and applying the rate. For channels which are less than one quarter mile,a minimum charge of one quarter mile applies.

J. The SMARTRing service Interoffice Channel mileage is calculated per quarter airline mile between two directly connectedcentral offices on the ring. Interoffice Channel mileage is computed by using the V&H coordinates method as set forth in theNATIONAL EXCHANGE CARRIER ASSOCIATION, INC. TARIFF F.C.C. No. 4. To determine the rate to be billed,multiply the appropriate per quarter mile rate by the distance involved. Fractions of a quarter mile always round up to the nextquarter mile before determining the mileage and applying the rate. For channels which are less than one quarter mile, aminimum charge of one quarter mile applies.

K. A nonrecurring charge applies for SMARTRing service Surveillance, one for each Customer Node andeach Central OfficeNode, per SMARTRing service rearranged. A nonrecurring charge applies for Reconfiguration, one per reconfiguration ofeach STS-1 group at each node where such reconfiguration capability is desired. These rate elements apply when the Customeradds FlexServ service to an existing SMARTRing service.

L. For SMARTRing service configured with a Virtual Packet Ring(s), an individual VPR requires multiple (i.e., two or more)Basic Shared Ethernet LAN Access Links.

M . For conversions of LightGate service to a higher capacity OC-12, OC-48, OC-48+, OC-192 or OC-192+ SMARTRing serviceand 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.

N. 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 LocalChannel and Interoffice Channel service components as requested by the customer.

O. 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. DIGITAL NETWORK SERVICE

B7.7 Self-Healing Multi-Nodal Alternate Route Topology Ring (SMARTRing) Service(Cont'd)

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

- Local Channel (at least one for each Customer Node which is directly connected to the serving wire center), providesfor the communications path between a Customer Node and the serving wire center of the premises where located.

- Alternate Central Office Channel (at least one for each Customer Node which is directly connected to an AlternateCentral Office), provides for the communications path, where requested, between a Customer Node and an AlternateCentral Office.

- Interoffice Channel (one for each path between each two directly connected Company Central Offices) provides forthe communications path between directly connected Company Central Offices located on a SMARTRing service.

- Internodal Channel (one for each path between two directly connected Customer Nodes), provides for thecommunications path, where requested, between two directly connected Customer Nodes located (a) in the sameServing Wire Center area or (b) in the same Office Park/Campus Environment or contiguous property, located incontiguous Serving Wire Center areas.

- Channel Interface Capacity Reallocation ( one per node per occurrence) allows the customer to reallocate channelinterfaces on anode subsequent to the initial installation of the channel interfaces. For example, a customer mayinitially allocate, activated or spare, eighty-four DS1s at eachnode on the ring and may subsequently request ChannelInterface Capacity Reallocation to drop one DS3 and fifty-six DS1s at each node, or other combination of DS3s and/orDS1s equivalent to an OC-3 network capacity.B7.7.4 Rates and Charges

- SMARTRing service OC-3, OC-12, or OC-48 channel interfaces are associated with optical circuits within aSMARTRing service arrangement. These optical circuits may be provisioned as concatenated. When an optical circuitis provisioned as concatenated, the multiple STS-1s within the optical circuit are provided as a single entity with asingle overhead channel.

- SMARTRing service interfaces may be ordered as asymmetrical (i.e., a circuit enters one node at a lower level interfaceand exits at another node at a higher level interface) For example, a customer may have a service that connects to aring via an OC-3 interface at a node. That service is then transported around the ring and connects via an OC-12interface to another of the customer’s services. The allowable asymmetrical interface arrangements for the various ringsizes are as shown in Technical Reference TR-73582.

- When the distance between nodes on a SMARTRing service (a.k.a. BellSouth SPA Dedicated Ring) is such that opticalsignal regeneration is required, then regeneration equipment will be provided at no additional charge to the customer toassure proper operation of the service. In some cases regeneration will be provided via SONET Add/Drop equipmentcalled a Regeneration Node. A Regeneration Node does not contain the capability to add or drop services.Accordingly, FlexServ service Customer Network Management may not be ordered with a Regeneration Node,however, a customer may monitor a Regeneration Node via the FlexServ service Customer Network ManagementSurveillance option when a customer has established surveillance for a ring. Regeneration Node Surveillance isprovided as a part of the charges associated with the customer’s ring level FlexServ service Customer NetworkManagement Surveillance. A Regeneration Node and Regeneration Node Surveillance, as applicable, will appear on acustomer’s records as a non-rated USOC, as follows:

USOCRegeneration Node, all ring capacities, non-rated SHNRD

Regeneration Node Surveillance, all ring capacities, non-rated SHNRS- SMARTRing service Virtual Packet Rings may be established to work with either electrical or optical Basic Shared

Ethernet 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 includingthe capacity 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.
