These SLAs apply only to Customers executing an agreement for Enterprise Mobility Dial Access with Corporate level SLA service.

The Global Network Accessibility, Global Network Login Success Rate, Global Network Throughput, and Average Connect Speed SLAs are based on Company-designated Points of Presence ("POPs") in the Company's Dial Access Network ("DAN") and certain third-party or non-DAN numbers ("Extended DAN").

Global Network Accessibility SLA

Global Network Accessibility SLA Scope:

The Global Network Accessibility SLA is that the percentage of successful dial-up connections established between Company rotary dial tools ("RDTs") and Company rotary groups ("RGs") for a given number of attempts shall equal or exceed 99% for the DAN and 93% for the Extended DAN.

Global Network Accessibility SLA Process:

RDTs dial at random into each RG on a continual basis. Global Network Accessibility for a month is determined by dividing the total number of successful test connections across all tested zones for that month by the total number of test calls across all tested zones for that month and multiplying the result by 100%. The calculation of Global Network Accessibility utilizes a weighted average associated with each zone tested. The weighted average may be adjusted once each quarter, based on the number of billed hours through each zone that is tested compared to the total number of billed hours through all zones. Testing zones are determined solely by Verizon Enterpise Solutions and may be adjusted from time to time. For the purposes of calculating Global Network Accessibility, a successful connection is any connection attempt that did not result in a busy signal. The DAN and the Extended DAN are tested separately.

Global Network Accessibility SLA Remedy:

Global Network Login Success Rate SLA

Global Network Login Success Rate SLA Scope:

The Global Network Login Success Rate SLA is that the percentage of successful PPP sessions established between RDTs and RGs for a given number of attempts shall equal or exceed 95% for the DAN and 85% for the Extended DAN.

Global Network Login Success Rate SLA Process:

RDTs dial at random into each RG on a continual basis. Global Network Login Success Rate for a month is determined by dividing the total number of successful test PPP sessions across all tested zones for that month by the total number of test calls across all tested zones for that month and multiplying the result by 100%. The calculation of Global Network Login Success Rate utilizes a weighted average associated with each zone tested. The weighted average may be adjusted once each quarter, based on the number of billed hours through each zone that is tested compared to the total number of billed hours through all zones. Testing zones are determined solely by Verizon Enterpise Solutions and may be adjusted from time to time. For purposes of calculating Global Network Login Success Rate, the number of successful test PPP sessions is defined as the total number of test calls placed minus the total number of test calls that did not result in the establishment of a successful test PPP session due to factors such as, but not limited to, a busy or dropped connection condition. The DAN and the Extended DAN are tested separately.

Global Network Login Success Rate SLA Remedy:

See below.

Global Network Throughput SLA

Global Network Throughput SLA Scope:

The Global Network Throughput SLA is average throughput of 100% for both the DAN and the Extended DAN.

Global Network Throughput SLA Process:

The Global Network Throughput SLA is based on the average time it takes an RDT to download a compressible file from a Company Internet FTP server using the FTP protocol over a dial-up connection. RDTs dial at random into each RG on a continual basis and attempt to download a specified compressible file. The file is compressed as part of the transmission process. Time spent before requesting the compressible file is not included in the measurement. The throughput for each test is determined according to the following formula:

The calculation of Global Network Throughput utilizes a weighted average associated with each zone tested. The weighted average may be adjusted once each quarter, based on the number of billed hours through each zone that is tested compared to the total number of billed hours through all zones. Testing zones are determined solely by Verizon Enterpise Solutions and may be adjusted from time to time.

The average of the results for all throughput tests performed in a month is the Global Network Throughput for that month. The DAN and the Extended DAN are tested separately.

Global Network Throughput SLA Remedy:

See below.

Average Connect Speed SLA

Average Connect Speed SLA Scope:

The Average Connect Speed SLA is 42Kbps for RGs with v.90 modems. The Average Connect Speed SLA applies globally to services on the DAN.

Average Connect Speed SLA Process:

The Average Connect Speed is calculated during the course of measuring the Global Network Throughput and is the average data transfer speed reported for all compressible file downloads between RDTs and RGs in a given month.

Average Connect Speed SLA Remedy:

See below.

Network Latency SLA

North American Network Latency SLA Scope:

The North American Network Latency SLA is average round-trip transmissions of 45 milliseconds or less between Company-designated inter-regional transit backbone network routers ("Hub Routers") in the contiguous United States.

European Network Latency SLA Scope:

The European Network Latency SLA is average round-trip transmissions of 30 milliseconds or less between Company-designated Hub Routers within Europe.

Transatlantic Network Latency SLA Scope:

The Transatlantic Network Latency SLA is average round-trip transmissions of 90 milliseconds or less between a Company-designated Hub Router in the New York metropolitan area and a Company-designated Hub Router in the London metropolitan area.

The Network Latency SLA is only available on the DAN.

Network Latency SLA Process:

Latency shall be measured by averaging sample measurements taken during a calendar month between Hub Routers.

Network Latency SLA Remedy:

See below.

Packet Delivery SLA

North American Packet Delivery SLA Scope:

The North American Network Packet Delivery SLA is packet delivery of 99.5% or greater between Company-designated Hub Routers in the contiguous United States.

European Network Packet Delivery Scope:

The European Network Packet Delivery SLA is packet delivery of 99.5% or greater between Company-designated Hub Routers within Europe.

Transatlantic Network Packet Delivery Scope:

The Transatlantic Network Packet Delivery SLA is packet delivery of 99.5% or greater between a Company-designated Hub Router in the New York metropolitan area and a Company-designated Hub Router in the London metropolitan area.

The Packet Delivery SLA is only available on the DAN.

Packet Delivery SLA Process:

Packet Delivery shall be measured by averaging sample measurements taken during a calendar month between Hub Routers.

Packet Delivery SLA Remedy:

See below.

Service Level Agreement Remedy

Company's performance with respect to each SLA shall be determined on the basis of Company data and testing of currently published, Company-designated POPs in the DAN, Company-designated Hub Routers, as indicated above, or currently published, third-party or non-DAN numbers. In calculating compliance with the above SLAs, Company will exclude (a) testing failures resulting from malfunction of testing infrastructure or software, (b) service or testing failures due to reasons of Force Majeure (as defined in the applicable service agreement) and, for the Extended DAN only, (c) testing failures resulting from local, long distance and international service malfunctions.

Customer may request a credit if Company's failure to meet any of the above SLAs in a given month has adversely affected Customer's use of dial-up services obtained from Company. To claim a credit, Customer must submit a complete Company claim form on or before the thirtieth (30) calendar day from the date the SLA results were posted. Customer's sole remedy for Company's failure to meet any and all SLAs shall be to receive a credit equal to the pro-rated charges for one (1) day of the Company dial-up access charges, net of discounts and taxes, billed to Customer for the month in which Company failed to meet the SLA for each SLA the Company has failed to meet. For any given month, the maximum credit available to Customers is a credit equal to nine (9) days of the pro-rated charges for one month of the Company dial-up access charges.
