Calculation
MTTR is a monthly average of the time taken to repair all Trouble Tickets on a specific service during a Network Outage. The length of each Network Outage on a specific service is totaled at the end of each billing month and divided by the corresponding number of Network Outages for that service. This is calculated from Trouble Tickets opened during that billing month. MTTR per billing month is calculated for the service as follows:
Cumulative length of Network Outage(s) per service
Total number of Trouble Tickets per billing month per service
Credit Structure
The credit calculation is based on the average repair times for all network outages within a calendar month. Credits for Type 1 access sites start when the average MTTR equals 2 hours. Credits for Type 2 & 3 access sites start when the average MTTR reaches four hours. Credits for Economy Frame Relay sites start with the average MTTR reaches six hours.
3. Network Transit Delay (NTD)
Definition
Network Transit Delay is defined as the round trip delay between the origination and destination infrastructure ports. It is the period of time that elapses between (i) the transmission of the ping packet from the origination infrastructure port and (ii) the receipt of the ping packet by the destination infrastructure port, in both directions of a PVC. The Company NTD SLG matrix does not include the access loop in the calculations.
Offering
For frame packet sizes less than or equal to 200 bytes, including protocol overhead, The Company's SLG for the NTD is 120 milliseconds or less for the Domestic U.S. Frame Relay network. Sites outside of the U.S. Mainland are covered with specific country to country round trip transit delay measures. The NTD measures for transport between U.S. and Non U.S. locations are posted in the Network Transit Delay Matrix of this document.
External factors that may cause delay, such as access serialization delay and access link congestion are excluded from the measurement.
Customers are expected to open Trouble Tickets when the NTD issue first surfaces. The Company will work with the customer to confirm the network transit times, repair problems and insure the customer's applications are functioning. The NTD SLG gives the Company thirty (30) calendar days to repair the NTD issue prior to the customer qualifying for credits.
Calculation
The Company's network ping test calculate NTD by summing the elapsed time in milliseconds measured as a round trip from the origination and destination infrastructure ports in each direction of the PVC.
Customers can complete ping test prior to opening a trouble ticket. The Company may opt to use the customer's ping test as a benchmark for the repair actions.
The formal NTD calculation is:
NTD = (Point A to Point B NTD = t2 t1) + (Point B to Point A NTD = t2 t1)
Where:
Point A is the Company origination infrastructure port
Point B is the Company destination infrastructure port
t1 is the time in milliseconds when a frame leaves the Ingress Reference Point (i.e., frame exit event)
t2 is the time in milliseconds when a frame arrives at the Egress Queue Output Reference Point (i.e., frame entry event.)
Credit Structure
The Company will confirm that specific PVC does or does not comply with the NTD expectation. In cases of non-compliance, the Company has thirty (30) calendar days to address the non-compliance and close the applicable Trouble Ticket without penalty. If the PVC continues to not meet this SLG after the 30-day period, the Customer may qualify for credits.
Enhanced Service Level Guarantees Defined
1. U.S. Domestic Service Installation Guarantee
Definition
Service Installation is the period of time between the date the Company accepts a complete installation order from the Customer for a new frame relay service located within the U.S. Mainland and the date the Company completes the installation of the service. A complete installation is defined as the point in the implementation where the customer can use the service. To qualify for the guarantee, the access circuit and port must be ordered by the Company and be physically located within the U.S. Mainland with a speed less than or equal to a DS1/T1 (1.536Mbps). The originating and terminating ports must be within the U.S. Mainland. The Customer must pay the installation charges for the access circuit, port and PVC. Utilization of promotional offerings on installation charges will disqualify the Customer from this SLG.
Offering
The SLG for Service Installation is forty-five days for new frame relay services with access circuits of less than or equal to T1/DS1 bandwidth.
Calculation
The SLG is calculated from the date the Company accepts the Customers order as complete for new frame relay service through the date on which the service has been installed and is ready for Customers use.
Credit Structure
The customer will receive a three hundred percent (300%) refund of their installation fees if the Company fails to install a circuit within 45 business days. Delays in installation related to customer actions, moves or scheduling difficulties are excluded from the installation interval calculation.
2. Frame Gold Enhanced Proactive Notification (EPN)
Definition
Frame Gold Enhanced Proactive Notification (EPN) is a Company service that provides the Customer with notification of a circuit outage. For the EPN SLG, the circuit outage will be defined as the lack of visibility to the circuit Link Management Indicator (LMI). After ten (10) consecutive minutes of circuit LMI loss, the Company Operations Service and Support Proactive Notification (OSS-PN) Group will receive an alarm and will begin to attempt to resolve the outage and will notify the Customer within thirty (30) minutes of the alarm report.
Offering
The Customer must subscribe to the Frame Relay Gold Service in order to receive the EPN SLG. Customers can sign-up by submitting a signed enrollment form for each circuit to be covered by the EPN SLG. EPN will only be provided on circuits enrolled in the Frame Relay Gold Service. This EPN SLG applies to DS0 and T1/DS1 circuits in the U.S. Mainland.
e Access circuits enrolled in the Frame Relay Gold Service will be closely monitored for loss of LMI. Once circuit LMI has been lost for ten (10) consecutive minutes, an alarm will notify the Company OSS-PN group to attempt to resolve the issue and notify the Customer. Following the alarm, the OSS-PN group will have thirty (30) minutes to notify the Customer that their circuit is experiencing a Circuit outage (Notification Period).
The Company will not be obligated to pay non-compliance credits when the OSS-PN group is unable to reach the Customer point of contact.
Calculation
The Notification Period begins after the ten (10) consecutive minute LMI loss alarm is reported. The Company has thirty (30) minutes to notify the customer from the start point of the Notification Period. The Company OSS-PN group will notify the Customer point of contact as indicated on the Enhanced Proactive Notification enrollment form.
Should the Customer contact the OSS-PN group within the Notification Period and before the OSS-PN group has initiated a call to the Customer, the Company will be deemed in compliance with the EPN SLG.
Credit Structure
The customer will receive a credit equal to three hundred percent (300%) of the monthly recurring (MRR) Frame Gold Service charge on the applicable access circuit. There is a limit of one credit per circuit in non-compliance per month.
Qualifications:
Credit Application Structure
The SLG credits are taken against the monthly recurring charges (MRR) for the port and/or PVC(s). The credits can be applied against PVC and/or Port charges as dictated by the outage type, either Hard or Soft. The credits are not cumulative month to month meaning the same schedule applies for each consecutive month should the outage exceed 30 days. The total credits within any one-month for the Standard SLGs is limited to a maximum of 40% of the MRR for Port and PVC(s). The Enhanced SLGs have unique credit maximums.
Customers are required to open a Trouble Ticket with the Company Customer Service Center at the time the service difficulty develops in order for the outage to qualify for an SLG credit. The Company, in its sole discretion, shall determine whether it complied with any and all SLGs and whether or not a credit is due to the customer. The Company commits to crediting the customer's account within 90 days following confirmation of non-compliance with the SLG.

Network Transit Delay Matrix for U.S. and U.S. to Non U.S. Transport:
Process for Determining the Round Trip Network Transit Delay:
The NTD SLGs is based on the geographic distance between existing trunk end points and a distance per mile packet measure.
For example, the NTD from the United States to Germany is based on the miles between a central trunk in the US and a central trunk in Germany. It is not based on the shortest distance between the U.S. and Germany. The transit delay measures in this matrix are expected to be worst case delays. External factors such as access serialization delay and access link congestion, which may cause delay, are excluded from the measurement.
