Non-emergency 311 Service (NE 311) is a local telephone exchange communications service which allows telephone customers to reach non-emergency local government services by dialing an abbreviated telephone number, three-one-one (3-1-1). NE 311 traffic is routed over the public switched network to destinations such as call centers designated by the NE 311 customer. The FCC reserved the abbreviated telephone number for non-emergency access to public services. NE 311 Service is an optional service which may be purchased by a local municipality, a council of governments, a communication district, or other state or local governmental unit, or an authorized agent of one or more municipalities or other state or local governmental units to whom authority has been lawfully delegated. The customer must be legally authorized to subscribe to the service. NE 311 Service is offered subject to the availability of facilities. B. REGULATIONS 1. A minimum service period of one month applies to this service. 2. Only calls originating within a NE 311 customer s area of jurisdiction (the NE 311 Service Area ) will be routed to a call center. Other customers will receive a recorded message that the call cannot be completed as dialed. 3. There can be only one NE 311 customer in each geographic area; NE 311 service areas may not overlap. This assures that NE 311 calls from a telephone line within a NE 311 service area can be routed to a unique NE 311 call center. 4. NE 311 is a local service. Each NE 311 call must route to a local telephone number. NE 311 calls are not permitted where local calling is restricted (e.g. prisons, or lines equipped with soft dial tone). 5. The Company s network will correctly route Telephone Text (TTY) calls to the appropriate NE 311 Call Center. The NE 311 customer is responsible for operating the appropriate customer premises to handle TTY calls. 6. The Company is not responsible for establishing NE 311 Service calls originating from other Telecommunications providers. ATT TN NV EFFECTIVE: October 1, 2007

Budget billing customers are charged each month based on estimated average monthly usage. b. For a new NE 311 customer, the average monthly usage will be estimated jointly by the customer and the Nevada Bell representative. The result will be rounded to the nearest 5000 calls. After six months actual usage is available, the estimate will be modified, as necessary. In addition, Nevada Bell reserves the right to negotiate changes to the budget billing estimated usage at any time. c. After an NE 311 customer has received service for twelve months. The monthly usage estimate will be calculated based on the average actual usage over a recent 12-month period, rounded to the nearest 5000 calls. d. The Budget Billing Option bill rendered will reflect the monthly Budget Billing Option level purchased by the customer. e. A monthly report will be provided to the customer to identify monthly cumulative variances. f. The customer may adjust their Budget Billing plan at any time. g. If the customer has more than a fifteen percent variance over three consecutive months. The customer is required to adjust their Budget Billing Option level either up or down to minimize an end-of-year true up. h. If the customer switches from the Billing Option to actual per call billing, a true up will be generated. i. If a customer who has selected the Budget Billing Option disconnects NE 311 Service, the actual usage will be calculated to perform an account true up for the final NE 311 bill. j.

14 645 E. Plumb Lane, Reno Nevada PART 6 - Central Office Services Original Sheet CENTRAL OFFICE SERVICES PREMIUM EXCHANGE SERVICES HUNTING SERVICE A. DESCRIPTION 1. Hunting Service is a feature which routes the call to an idle line in a prearranged group when the called line is busy. The hunting sequence over these prearranged groups can be accomplished as follows: a. Series Complete hunting is a type of hunting in which the hunt for an idle line starts with the called line in a prearranged group and ends with the last line in the group, completing the call to the first idle line encountered. Unless the first line is called only a portion of the group is hunted. b. Circular hunting is a type of line hunting in which the hunt for an idle line starts with the called line and proceeds in a proceeds in a prearranged order to hunt all lines in the group once, completing the call to the first idle line encountered. When the hunt for an idle line commences beyond the first line in the hunt group and finds all higher numbered lines busy, the hunt returns to the first line in the group. The hunt ends with the line number preceding the starting line where the hunt in the group initially began. c. Preferential hunting is a type of line hunting which permits a prehunt over a subset or preferential group of terminal before hunting through the prearranged group. The hunt through the prearranged group can be a regular or circular hunt. d. Uniform Call Distribution (UCD) is a type of hunting which provides for an even distribution of incoming calls among the available members of a hunt group. UCD requires the prearranged group to have circular hunting. B. APPLICABLITY Applicable to Individual Line or PBX Trunk Line Service. C. TERRITORY Within the territory served.

16 645 E. Plumb Lane, Reno Nevada PART 6 - Central Office Services Original Sheet OTHER CENTRAL OFFICE SERVICES CUSTOMIZED SWITCHED METRO ETHERNET (CSME) SERVICE A. BASIC SERVICE DESCRIPTION Customized Switched Metro Ethernet Service (CSME Service) is a switched Layer 2 Ethernet network allowing for basic metropolitan Ethernet connectivity. CSME Service allows businesses to interconnect multiple customer locations within a LATA as if they were segments on the same LAN using packet-based switching technologies. Connections at the customer premises are made using Native Ethernet interfaces and traverse the MAN over fiber facilities. CSME Service provides bandwidth of either 10 Mbps, 100 Mbps or 1 Gbps 1. Customers connect to CSME Service via one of the following standard connections, as requested by the customer: - 10/100 Base T (10 Mbps or 100 Mbps) - Gigabit Ethernet (1000 Base SX, 1000 Base LX/LH or 1000 Base ZX) Customers may connect multiple locations together, as long as they are in the same LATA or MAN and the service is available. This service acts as an Ethernet bridge supporting LAN-to-LAN connections. CSME Service includes the connection from the customer s premise to the Ethernet network, a port on the Ethernet network and the bandwidth that will be used across the network. An optional feature is the ability to segregate customer traffic, as deemed necessary by the customer. This traffic segregation is accomplished using Ethernet Virtual Connections (EVCs), at an additional charge. Note 1: Bandwidth is inclusive of allowances for overhead within the Ethernet network. If a customer orders 1 Gbps of bandwidth on a single port, the Company reserves the right to use up to 10% of the bandwidth for traffic management. ATT TN NV EFFECTIVE: October 1, 2007

SERVICE COMPONENTS 1. There is one standard (or required) rate element which applies for CSME Service: Usage, Port, Transport and Interface. Usage, Port, Transport and Interface Provides for the physical connection between the customer s premise and the serving wire center, as well as the bandwidth that will be used by the customer at each location. Several interface protocols are available: 10/100 Base T and Gigabit Ethernet (1000 Base SX, 1000 Base LX/LH or 1000 Base ZX). 2. In addition, there are optional rate elements which may apply to CSME, depending on the customer s configuration: (D) (D) Additional MAC Addresses Media Access Control (MAC) Addresses denote a data link layer protocol used for Layer 2 connectivity. If a customer connects to the CSME network using a bridge or switch for Layer 2 connectivity, only 150 MAC addresses can be used per Layer 2 device, per port. Any additional addresses over the first 150 will be assessed an additional charge, with a limit of 200 MAC addresses total per port. An additional charge will be assessed per block of addresses. Ethernet Virtual Connections (EVCs) An Ethernet Virtual Connection is a logical point-to-point connection between two customer locations, and goes from the customer demarcation point at one location through the network to terminate at the demarcation point at the second customer location. Customers use EVCs if they desire traffic segregation, but EVCs will not provide for traffic prioritization. EVCs may be ordered to establish additional virtual connections over the same physical connection. When EVCs are ordered, the customer must designate the amount of bandwidth to be assigned to each EVC. EVCs can be set in 1 Mbps increments from 5 Mbps to 1 Gbps. Meet-Point Billing Options Meet-Point is available in two configurations: (N) Direct LEC Connection is provisioned using a standard CSME Connection, plus Mileage. The mileage is measured in airline miles from the CSME switch location to the ILEC (ICO) meetpoint location. GigE ICO Trunking Arrangement applies an ICO Trunk Connection Charge between the CSME switch location and the ICO meet-point location that is shared with the ILEC (ICO) Ethernet switch. The ICO Trunk Connection Charge is applied to each customer Ethernet Virtual Connection (EVC) that is transported on the GigE trunk backbone to the ICO meet-point. The ICO Trunk Mileage charge is applicable to each customer Ethernet Virtual Connection (EVC) transported across the GigE trunk when mileage exceeds 10 miles. Mileage is calculated from the CSME switch location to the ICO meet-point location. (N) Repeater For those customers who are located outside normal transmission parameters, service can be provided using a repeater to be placed in Company wire centers. An engineering study will be completed to ensure transmission parameters can be met using a repeater, and the Company will determine when Repeaters are necessary. Additional charges will apply. Provisioning of CSME Service is subject to the availability and operational limitations of the equipment and associated facilities. ATT TN NV EFFECTIVE: April 1, 2009

Recurring rates may be applied only over a 36 or 60 /1/ month period under the terms and conditions of the Term Pricing Plan (TPP). Upon completion of a TPP, a customer s service will automatically convert to the Monthly Extension rates unless the customer requests a new TPP. No customer shall purchase CSME Service on a month-to-month basis prior to the completion of a TPP. 2. The TPP provides for 36 or 60 /1/ month rate stabilization. Decreases in term monthly recurring Guidebook rates will be passed on to customers who participate in a TPP. Should the Company increase its rates during the TPP period, the customer would continue to pay the rates in effect at the time the customer elected to establish service under the TPP. 3. The customer may choose to terminate an existing TPP before the end of the 36 or 60 /1/ month period and negotiate a new 36 or 60 /1/ month TPP. The new TPP must be based upon the rates that are currently in effect and available to all customers. 4. The customer must provide the Company with a written notice of intent to renew a TPP no later than 90 days prior to its expiration. If the customer elects not to renew the TPP, or does not notify the Company of the customer s intent to renew the TPP, the service will automatically be billed under the Guidebook monthly extension rates in effect at the time that TPP expires. Subsequently, customers under the Guidebook monthly extension rates may convert their existing service to either a 36 or 60 /1/ month TPP. Nonrecurring charges will be waived at the time of conversion. (C) (C) (C) (C) (C) 5. Any Special Construction charges incurred for services billed under a TPP will be applicable. 6. If the customer terminates the TPP agreement prior to the expiration of the service term, the customer shall pay a termination charge. Payment of the termination charge does not release the customer from other previous amounts owed to the Company. In addition to any unpaid Special Construction or nonrecurring charges (excluding any waived charges), Termination Charges will be equal to: - Fifty percent (50%) of all recurring charges for the remaining months of the customer s term. /1/ Effective November 15, 2013, customers may not establish new term plans greater than 36 months for CSME Service, and existing term plans greater than 36 months may not be renewed or extended for a term greater than 36 months.

29 PART 6 - Central Office Services Original Sheet 27 AT&T SWITCHED ETHERNET SERVICE SM A. Description AT&T Switched Ethernet Service is a switched Ethernet transport service providing Ethernet transport functionality using fiber and copper access facilities and a switched Ethernet core network. AT&T Switched Ethernet Service provides full duplex transport of data signals between a Customer s premises /1/ and an Ethernet switch in a Company central office. AT&T Switched Ethernet Service supports point-to-point, point-to-multipoint or multipoint-to-multipoint configurations. Point-to-point service provides a connection between two ports. Point-to-multipoint service provides multiple point-to-point connections to multiple ports in the network. Multipoint-tomultipoint service provides a connection between three or more designated ports on the AT&T Switched Ethernet Service network. The Company shall determine the interface specifications for AT&T Switched Ethernet Service in its sole discretion. Customers may obtain the interface specifications from their account representatives. AT&T Switched Ethernet Service provides intralata transport service where suitable equipment and facilities are available. Where facilities are not available, facilities may be constructed, subject to certain conditions as determined by the Company. Special Construction charges may apply. AT&T Switched Ethernet Service is available in two serving arrangements, the Basic Service Arrangement and the Per Packet Class of Service (PPCoS) Arrangement, and two types of Customer port connections, Basic Ports and Per Packet Class of Service Ports. Service will be provisioned using the service components described below. Unless specifically stated otherwise, all references to Customer Port Connections or ports shall be deemed to refer to Basic Ports and PPCOS Ports. Basic Service Arrangement This type of service provides transport of data using a fixed class of service for each Ethernet virtual connection. The Customer must select a CIR for each Basic Port. The CIR for the Basic Service Arrangement has five choices for fixed CoS. The CIR selected cannot exceed the Customer Port Connection capacity. The table below shows the CIR available for each Customer Port Connection. Customer Port Connection CIR Bandwidth Supported 100 Mbps 2 Mbps 100 Mbps 1 Gbps 2 Mbps 1000 Mbps 10 Gbps 1000 Mbps 10,000 Mbps /1/ Hereinafter, the phrase Customer s premises and Customer location (or similar terms) shall be construed to include an end user s premises, as appropriate in the context, where the Customer is a Wholesale Customer and service is terminated at the premises of an end user that is not the Customer of record of the Company.

30 PART 6 - Central Office Services Original Sheet 28 A. Description (Cont d) Basic Service Arrangement (Cont d) Basic Customer Port Connection (Basic Port) This component provides the physical transport facilities from the Customer s premises to an Ethernet switch at the Company central office. The Customer Port Connection is available at transmission speeds of 100 Mbps, 1 Gbps and 10 Gbps. Committed Information Rate (CIR) and Class of Service (CoS) CIR, sometimes referred to as the Logical Channel of the port, provides the bandwidth available on a Customer Port Connection. CIR is available per Customer Port Connection in increments ranging from 2 Mbps to 10,000 Mbps. CIR is offered with multiple choices for CoS. CoS establishes the performance characteristics of the network that are suitable for certain applications. Each Customer Port Connection (port) has a single CIR and CoS associated with it. CoS options are listed as a hierarchy, from highest to lowest based on network prioritization and performance as follows: Real-Time: Supports applications that require minimal loss, are latency-sensitive and require low latency variation (jitter), including voice and video. The service parameters associated with Real- Time CoS are Packet Delivery Rate (PDR), Latency, Jitter and Network Availability. Interactive: Supports high-priority business data applications or jitter-sensitive applications such as voice and video. The service parameters associated with Interactive CoS are PDR, Latency, Jitter and Network Availability. Business Critical-High: Supports most business data applications with moderate tolerance for delay and which are more sensitive to jitter and have a higher priority than Business Critical- Medium. The service parameters associated with Business Critical-High CoS are PDR, Latency, and Network Availability. Business Critical-Medium: Supports most business data applications with moderate tolerance for delay and which are less sensitive to jitter. The service parameters associated with Business Critical-Medium CoS are PDR, Latency, and Network Availability. Non-Critical High: Supports low priority business applications with more tolerance for delay and availability. The service parameters associated with Non-Critical High CoS are PDR, Latency, and Network Availability. ATT TN 2053 EFFECTIVE: February 16, 2013

31 PART 6 - Central Office Services First Revised Sheet 29 A. Description (Cont d) Basic Service Arrangement (Cont d) Ethernet Virtual Circuits (EVC) An EVC provides a logical connection to enable the flow of Ethernet traffic for point-to-point and multipoint Customer configurations. Standard EVCs are not billed to the Customer as a separate rate element. Each EVC is assigned a CIR and CoS that must be equal to or lower than the CIR and CoS of the Port. Point-to-point connections EVCs can be set in 1 Mbps increments from 1 Mbps to 2000 Mbps. Multipoint EVCs can be set in 1 Mbps increments from 1 Mbps to 1000 Mbps. Requests for EVC CIR above these limits will be evaluated on an Individual Case Basis, taking into consideration factors such as facility conditions and the impact of the requested configuration on network performance. The total assigned bandwidth (sum of the CIR for all EVCs) on a single port cannot exceed the selected CIR of that port. Point-to-point EVCs must be symmetrical; the EVC CIR at each port must be the same. For multipoint EVCs, the CIR for any EVC may be set according to the bandwidth needed at that port and does not need to be the same at all ports. Ports that do not meet SLA objectives due to overloading of traffic in a multipoint arrangement will not be eligible for the PDR SLA. The aggregate assigned CIR for all EVCs between any two Customer Port Connections cannot exceed 2000 Mbps (for point-to-point EVCs) or 1000 Mbps (for multipoint EVCs), except when approved on an Individual Case Basis. The following chart provides the maximum number of EVCs supported for point-to-point and multipoint configurations on each Customer Port Connection: Per Customer Port Connection EVCs 100 Mbps Up to 8 EVCs 1 Gbps Up to 64 EVCs 10 Gbps Up to 508 EVCs Customers may configure EVCs as point-to-point (connecting two locations) or as multipoint (connecting three or more locations), as defined above. Point-to-point EVCs (i.e. EVCs between two ports) can be associated with an unlimited number of MAC addresses. Multipoint EVCs (i.e., EVCs between three or more ports) will be limited to 250 MAC addresses per multipoint EVC on that port, unless the Customer purchases the Additional MAC Addresses optional feature. MAC addresses associated with point-to-point EVCs do no count against this limit. For example, a port that is provisioned with 3 separate multipoint EVCs may have up to 250 MAC addresses associated with each of those EVCs, for a total of 750 MAC addresses in use on that port, but each EVC is still limited to a maximum of 250 MAC addresses.
