Service Level Standard 1 Circuit Installation

Installation Scope. Verizon's Circuit Installation Service Level Standard is to have installation of a Verizon-ordered telephone company circuit and activation of a Verizon port completed within forty (40) business days for T1 services, sixty (60) business days for T3 services, and within the scheduled installation date provided in writing by a Verizon Sales Manager for OC-3, OC-12, OC-48, FE Port Only, and Internet Dedicated Ethernet (and GigE) services.

Installation Process. The installation date shall be counted from the date Verizon has received all of the following from Customer: signed contract (e.g., Service Agreement or Amendment), completed Customer Information Form, and (if requested by Verizon) completed credit application. The Circuit Installation Service Level Standard is not available for Customer-ordered telephone company circuits, Verizon-ordered telephone company circuits outside the contiguous U.S., or if installation delay is attributable to Customer equipment, Customer's facility, acts or omissions of Customer, its employees or agents, Customer not passing Verizon's credit check, or reasons of Force Majeure (see below if not defined in the applicable service agreement).

Installation Remedy. To claim a credit, Customer must request it by calling the Billing Inquiry/Trouble telephone number on its invoice. At the time of the call, Customer must provide the company name, account number, circuit ID, name of the service (Internet Dedicated), contact name and number, email address, Service Level Standard installation date, and the actual installation date in order to process the request. If Verizon determines in its reasonable commercial judgment that it has not met a Circuit Installation Service Level Standard, then at Customer's request, Customer's invoice will be credited an amount equal to 50% of Verizon's billed installation charge, to include any applicable Internet Port/service installation charges and Verizon-ordered and -billed access installation charges for the Internet Dedicated Service for which the Circuit Installation Service Level Standard was not met.

Service Level Standard 2 - Availability

Service Availability Scope. Verizon's Service Availability Service Level Standard provides that the Verizon Network (as defined in the applicable service agreement) will be available 100% of the time.

Service Availability Process. At Customer's request, Verizon will calculate Customer's "Network Unavailability" during a calendar month. "Network Unavailability" consists of the number of minutes that the Verizon Network or a Verizon-ordered access circuit in the contiguous U.S. was not available to Customer, and includes unavailability associated with any maintenance at the Verizon data center where Customer's circuit is connected or Customer's server is located other than Scheduled Maintenance (defined below). Outages will be counted as Network Unavailability only if Customer opens a trouble ticket with Verizon Customer support within four (4) hours from learning of the outage. Network Unavailability will not include Scheduled Maintenance, or any unavailability resulting from (a) any Customer-ordered telephone company circuits or equipment, (b) Customer's applications or equipment, (c) acts or omissions of Customer or user of the Internet Dedicated Service authorized by Customer or (d) Force Majeure (see below if not defined in the applicable service agreement). If Verizon fails to meet this Service Level Standard during any given calendar month in accordance with the above, Customer's account will be credited at Customer's request.

Service Availability Remedy. To receive credit for a failure to meet a Service Level Standard, Customer must request such credit within 30 days from the date that the Internet Dedicated Service was unavailable. For each cumulative hour of Network Unavailability or fraction thereof in any calendar month, at Customer's request, Customer's account shall be credited for the pro-rated charges for one day of the Verizon I monthly recurring charge plus one day of the telephone company line charges for the Service with respect to which a Service Availability Service Level Standard was not met.

Service Level Standard 3 Latency

Latency Scope. Verizon's U.S. Latency Service Level Standard provides for average round-trip transmissions of 45 milliseconds or less between Verizon-designated inter-regional transit backbone routers ("Hub Routers") in the contiguous U.S. Verizon's Transatlantic Latency Service Level Standard provides for average round-trip transmissions of 90 milliseconds or less between a Verizon Hub Router in the New York metropolitan area and a Verizon Hub Router in the London metropolitan area. Latency is calculated by averaging sample measurements taken during a calendar month between Hub Routers.

Latency Remedy. If Verizon fails to meet the Latency Service Level Standard in a calendar month, Customer's account shall be automatically credited for that month. The credit will equal the pro-rated charges for one day of the Verizon monthly recurring charge for the Internet Dedicated Service with respect to which the Service Level Standard has not been met. Credits will not be issued if failure to meet either the U. S. Latency Service Level Standard or the Transatlantic Latency Service Level Standard is attributable to reasons of Force Majeure (see below if not defined in the applicable service agreement).

Service Level Standard 6 - Reporting Service Level Standard

Verizon provides two types of reporting Service Level Standards a Network Outage Notification Service Level Standard and a Scheduled Maintenance Notification Service Level Standard. Verizon's Network Outage Service Level Standard provides Customer notification within 15 minutes after it is determined that Internet Dedicated Service is unavailable. Verizon's standard procedure is to ping Customer's router every five minutes. If the router does not respond after two consecutive five-minute ping cycles, Verizon will deem the Internet Dedicated Service unavailable and the Customer's point of contact will be notified by e-mail, phone or pager, as elected by Verizon.

Scheduled Maintenance. Scheduled Maintenance means any maintenance at the Verizon hub to which Customer's circuit is connected (a) of which Customer is notified seven calendar days in advance, and (b) that is performed at the Verizon hub to which Customer's circuit is connected. Notice of Scheduled Maintenance will be provided to Customer's designated point of contact by email or pager, as elected by Verizon. Upon receiving such notice, Customer may request to have such maintenance postponed to a later date if agreed to by Verizon.

Notification. To obtain the benefit of being proactively notified of outages and maintenance activity under this Service Level Standard, Customers subscribed to Verizon's Rapid Delivery ("VRD") contracting platform must enroll in the Network Outage Notification Service and the Scheduled Maintenance Notification Service (accomplished via Customer's account manager or Verizon Customer Service). Customers on Verizon's legacy contracting platform are automatically enrolled.

Force Majeure. Any delay in or failure of performance by Verizon will not be considered a breach of this Service Level Standard if and to the extent caused by events beyond its reasonable control, including, but not limited to, acts of God, embargoes, governmental restrictions, strikes, lockouts, work stoppages or other labor difficulties, riots, insurrection, wars, or other military action, acts of terrorism, civil disorders, rebellion, fires, floods, vandalism, or sabotage (Force Majeure). Verizon's obligations hereunder will be suspended to the extent caused by Force Majeure so long as the Force Majeure continues.

Service Level Standard 7 - Network Jitter Service Level Standard (currently applicable only in U.S.)

U.S Network Jitter Scope. Also known as delay variation, Jitter is defined as the variation or difference in the end-to-end delay between received packets of an IP or packet stream. Jitter is usually caused by imperfections in hardware or software optimization and varying traffic conditions and loading. Excessive delay variation in packet streams usually results in additional packet loss, which affects quality. Verizons North American Network jitter performance will not exceed 1 milliseconds between Verizon-designated inter-regional transit backbone network routers Hub Routers in the contiguous U.S.

Network Jitter Process. Jitter shall be measured by averaging sample measurements taken during a calendar month between Hub Routers. Each month's Network performance statistics relating to the Network Jitter Service Level Standards shall be posted at http://www.verizonbusiness.com/about/network/latency. No credits will be made if failure to meet a Network Jitter Service Level Standard is attributable to reasons of Force Majeure (as defined in the applicable service agreement).

Network Jitter Service Level Standard Remedy. If Verizon fails to meet Jitter Service Level Standard in a calendar month; Customer's account shall be automatically credited for that month for the pro-rated charges for one day of the Verizon Monthly Fee for the service with respect to which Jitter Service Level Standard has not been met.

Service Level Standard 8 - Mean Opinion Score ("MOS") Service Level Standard (currently applicable only on the U.S. Mainland)

MOS Scope. Mean Opinion Score is a measure (score) of the audio fidelity, or clarity, of a voice call. It is a statistical measurement that predicts how the average user would perceive the clarity of each call. The Verizon Internet Dedicated MOS Service Level Standard provides that Verizon's U.S. Mainland Network MOS performance not be less than 4.0 between Verizon-designated inter-regional transit backbone network routers ("Hub Routers") in the contiguous United States. MOS is calculated using the standards based E-model (ITU-T G.107).

MOS Process. Credits will not be issued if failure to meet the MOS Service Level Standard is attributable to reasons of Force Majeure (as defined in Service Level Standard.6 above, if not defined in the applicable service agreement.)
MOS Service Level Standards shall be posted at http://www.verizonbusiness.com/about/network/latency.

MOS Remedy. To receive a credit, Customer must submit a request within 30 business days after Service Level Standard results for the preceding month have been posted and which indicate that the MOS Service Level Standard has not been met. Customers account will be credited a pro-rated amount of the monthly recurring charges equivalent to one days Internet Dedicated Service plus one day of the access line charges for the Internet Dedicated Service.

Service Level Standard 9 Time to Repair ("TTR") Service Level Standard

TTR Service Level Standard Scope. Calculation of Customers TTR Service Level will be based on the time taken to restore service to a circuit following an event that results in the outage of a circuit. The TTR Service Level Standard for Internet Dedicated Services is 4 hours. The TTR time starts when a trouble ticket is opened by Verizon or the Customer after the outage of a circuit other than for outages associated with the exceptions stated below, and concludes with the restoration of the affected circuit. TTR Service Level Standard applies to the Local Access line and the WAN infrastructure port.

TTR Service Level Standard Process. Outages will be counted only if Customer opens a trouble ticket with Verizon Customer support within (30) days of the outage. Calculation of the TTR Service Level Standard does not count as a covered outage any outage resulting from (a) scheduled Maintenance; (b) any Customer-ordered telephone company circuits or equipment; (c) Customer's applications or equipment; (d) acts or omissions of Customer, non-Verizon affiliated third parties or user of the circuit authorized by Customer; or (e) Force Majeure (as defined below if not defined in the applicable service agreement). If Verizon does not meet the TTR Service Level Standard during any calendar month Customer's account will be credited at Customer's request.

TTR Service Level Standard Remedy. To receive a credit, Customer must submit its request within 30 days after the month in which the TTR Service Level Standard was not met. Such credit will equal the pro-rated charges for one day of the Verizon Monthly Fee for the affected Service with respect to the calendar month the TTR Service Level Standard has not been met. The TTR Service Level Standard Remedy is not available to Customer if Customer has requested a credit under the Service Availability Standard.
