Comcast may charge Customer nonrecurring and monthly recurring cross-connect charges to make such connections.


    The technical specifications applicable to the Service are set forth in Schedule A-1 hereto. The service level agreement applicable to the Service is set forth in a Schedule A-2 hereto.



    Comcast’s Ethernet Dedicated Internet Service (“Service”) will be provided in accordance with the service descriptions, technical specifications set forth below:

    Service Descriptions

    Ethernet Dedicated Internet Service (EDI). EDI provides reliable, simple, and flexible access to the Internet. The Service is offered with a 10Mbps, 100Mbps, 1Gbps, 10 Gbps Ethernet User-to-Network Interfaces (UNI) and is available in speed increments starting at 1Mbps, subject to available capacity. The Service provides an Ethernet Virtual Connection (EVC) from the Customer Service Location to a Comcast Internet Point of Presence (POP) router.

    Threat Management Services.  TMS is a managed security service that includes threat protection functionality to respond to cyber-attacks on Internet connections, including both distributed denial of service (“DDoS”) and application layer attacks.  TMS Service is available to Customer two ways:

    1) Emergency DDoS Protection. Upon notification of suspicious traffic from Customer, Comcast will analyze traffic for anomaly detection and patterns to determine whether the business is under a DDoS attack.  In performing this analysis Comcast will gather the appropriate network information (e.g., routable IP addresses). When authorized by Customer, Comcast will redirect Customer’s incoming Internet traffic to Comcast scrubbing centers to filter the malicious traffic matching specific attack vectors and re-route legitimate traffic back to Customer’s Internet connection. In order to purchase Emergency DDoS Protection, Customer must have Comcast EDI Service. 

    2) Threat Management Service (TMS).  TMS is a Comcast network-based managed Service with threat protection functionality to respond to both DDoS and application layer attacks. Customer must have EDI Service to subscribe to TMS. Upon receipt of complete and accurate Customer contact and network information, Comcast will configure Customer’s site(s), related IP addresses, and preconfigure countermeasure options. Customer will be notified to contact Comcast to perform an acceptance test. Customer has five (5) business days to contact Comcast to initiate the acceptance test to confirm that TMS is configured in accordance with Customer’s preferences after activation and to verify the operation of TMS. TMS is a subscription-based Service offering that provides Customer with proactive network detection of DDoS attack traffic, alert notifications and mitigation of attacks.

    Comcast monitors the Customer network traffic for a specified set of IP addresses. When the DDoS attack traffic is detected, an alert is sent to both Comcast operations center and the customer via emails and SMS. During the mitigation, Comcast diverts customer’s traffic including DDoS attack traffic directed at the customer servers to Comcast’s scrubbing centers distributed across the U.S. to filter the malicious traffic matching specific attack vectors. Simultaneously, the clean legitimate traffic is routed to the customer’s network and servers. After mitigation is terminated, all traffic is re-directed back to the Internet connections via normal paths.

    Customer has a choice of On-Demand or Automatic protection options. With the On-Demand option, Customer must authorize Comcast by phone to initiate protection. Time to mitigate is the elapsed time from when the customer authorizes Comcast to enable protection until Comcast initiates mitigation of any attack traffic.

    With the Automatic protection option, no Customer intervention is required. Comcast’s scrubbing platform automatically initiates mitigation when an alert is generated due to the detection of attack traffic exceeding pre-set thresholds. Time to Mitigate is the elapsed time from when the alert is generated to when Comcast initiates mitigation of attack traffic. 

    For those Customers receiving TMS Service under section 2 above that request additional Protection Incidents beyond the pre-determined limits ordered, incremental charges shall apply. A “Protection Incident” is defined as one (1) twenty-four (24) hour window in which Comcast provides Customer with protection against DDOS attacks, including the mitigation of attack traffic.

    EDI Technical Specifications.

    1. Ethernet User-to-Network Interface.   The Service provides the bidirectional, full duplex transmission of untagged Ethernet frames using a standard IEEE 802.3 Ethernet interface (UNI) to attach to the customer’s router.  Figure 1 lists the available UNI physical interfaces and their available Committed Information Rates (CIR) bandwidth increments and Committed Burst Sizes (CBS). CIR increments of less than 10 Mbps are generally not available in conjunction with Off-Net Services. 

    2. Traffic Management.   Comcast’s network traffic-policing policies restrict traffic flows to the subscribed, Committed Information Rate (CIR).  If the Customer-transmitted bandwidth rate exceeds the subscription rate (CIR) and committed burst size (CBS), Comcast will discard the non-conformant packets.  The Customer’s router must shape their traffic to their contracted CIR. Traffic management policies associated with any Off-Net portions of Service will conform to the policies enforced by the third-party service provider.

    3. Maximum Frame Size.  The Service supports a maximum transmission unit (MTU) frame size of 1518 bytes including Layer 2 Ethernet header and FCS.

    4. Layer 2 Control Protocol (L2CP) Processing. All L2CP frames are discarded at the UNI.

    5. IP Address Allocation.  IP address space is a finite resource that is an essential requirement for all Internet access services. Comcast assigns eight (8) routable IP addresses to each customer circuit.  Customer can obtain additional IP addresses if required based on ARIN guidelines and by completing an IP address request form; additional charges may apply.

    6. Domain Name Service.  Comcast provides primary and secondary Domain Name Service (DNS).  DNS is the basic network service that translates host and domain names into corresponding IP addresses, and vice-versa.

    7. Border Gateway Protocol (BGP) Routing.  Comcast supports BGP-4 routing as an optional service feature. BGP-4 allows Customers to efficiently multi-home across multiple ISP networks.  The Service requires an Autonomous System Number (ASN) be assigned to a customer by the American Registry for Internet Numbers (ARIN).  Customers should also be proficient in BGP routing protocol to provision and maintain the Service on their router.   Additional information and requirements for BGP routing will be provided to the customer upon request.  Comcast supports private peering if the Customer is multi-homed to Comcast’s network only.

    8. Online Reporting.   Comcast provides the Customer with a password-protected web portal to access online reports containing their historical network traffic information. Reports may vary based on the Customer’s Service.



    Comcast’s Ethernet Dedicated Internet Service is backed by the following Service Level Agreement (“SLA”):

    A. Definitions

    Capitalized terms not otherwise defined herein shall have the meaning ascribed to them in the Ethernet Dedicated Internet Services PSA or the General Terms and Conditions.

    “Planned Service Interruption”
    means any Service Interruption caused by planned work such as scheduled maintenance or planned enhancements or upgrades to the network.

    “Service Interruption” means a failure of the Service to meet the specifications set forth in Schedule A-1 to the
    Product-Specific Attachment for Ethernet Dedicated Internet Services.

    B. EDI Service Level Agreement (SLA) 

    Company’s liability for mistakes, errors, omissions, interruptions, delays, outages, or defects in transmission or switching of any Service (individually or collectively, “Liability”), shall be limited to the amounts set forth in the Tables below.  The term "Liability" refers to an interruption in transmission that renders the Service unusable due to a total loss of signal for the service or the output signal presented to the customer from Comcast does not conform to the technical specifications in A-1 above. For the purposes of calculating credit for any such Liability, the Liability period begins when the Customer reports to Company an interruption in the portion of the Service, provided that the Liability is reported by Customer during the duration of the Liability, and, a trouble ticket is opened; the Liability shall be deemed resolved upon closing of the same trouble ticket or the termination of the interruption, if sooner, less any time Company is awaiting additional information or premises testing from the Customer.  In no event shall the total amount of credit issued to Customer’s account on a per-month basis exceed 50% of the total monthly recurring charge (“MRC”) associated with the impacted portion of the Service set forth in the Sales Order. Service Interruptions will not be aggregated for purposes of determining credit allowances. To qualify, Customer must request the Credit from Comcast within thirty (30) days of the interruption.  Customer will not be entitled to any additional credits for Service Interruptions. Comcast shall not be liable for any Liability caused by force majeure events, Planned Service Interruptions or Customer actions, omission or equipment.

    Monitoring, Technical Support and Maintenance

    1. Network Monitoring. Comcast monitors On-Net Service on a 24x7x365 basis.

    2. Technical Support. Comcast provides a toll-free trouble reporting telephone number to the Enterprise Technical Support (ETS) center that operates on a 24x7x365 basis.  Comcast provides technical support for service-related inquiries.  Technical support will not offer consulting or advice on issues relating to CPE or other equipment not provided by Comcast.

    a. Escalation. Reported   troubles   are   escalated   within   the   Comcast   Business Enterprise Technical Support center (“ETS”)   to   meet   the response/restoration interval described below (Response and Restoration Standards). Service issues are escalated within  Comcast ETS as follows:  to a Supervisor at the end of the applicable time interval plus one (1) hour; to a Manager at the end of the applicable time interval plus two (2) hours, and to a Director at the end of the applicable time interval plus four (4) hours.

    b. Maintenance.  Comcast’s standard maintenance window for On-Net Services is Sunday to Saturday from 12:00am to 6:00am local time.  Scheduled maintenance for On-Net Services is performed during the maintenance window and will be coordinated between Comcast and the Customer. Comcast provides a minimum of forty-eight (48) hour notice for non-service impacting scheduled maintenance. Comcast provides a minimum of seven (7) days’ notice for service impacting planned maintenance. Emergency maintenance is performed as needed without advance notice to Customer. Maintenance for Off-Net Services shall be performed in accordance with the applicable third party service provider rules. Therefore, Off-Net Service may be performed without advance notice to Customer.

    3. Comcast provides certain Comcast Equipment for provisioning its services and the delivery of the UNI, which will reside on the Customer-side of the Demarcation Point. Comcast will retain ownership and management responsibility for this Comcast Equipment. This Comcast Equipment must only be used for delivering Services. Customers are required to shape their egress traffic to the Committed Information Rate (“CIR”) identified in the Sales Order. Comcast will be excused from paying SLA credits if the Service Interruption is the result of Customer’s failure to shape their traffic to the contracted CIR or utilizing Comcast Equipment for non-Comcast provided services.

    Response and Restoration Standards

    Comcast has the following response and restoration objectives:

    Customer shall bear any expense incurred, e.g., dispatch/labor costs, where a Service Interruption is found to be the fault of Customer, its end users, agents, representatives or third-party suppliers.

    Emergency Blocking

    The parties agree that if either party hereto, in its reasonable sole discretion, determines that an emergency action is necessary to protect its own network, the party may, after engaging in reasonable and good faith efforts to notify the other party of the need to block, block any transmission path over its network by the other party where transmissions do not meet material standard industry requirements.  The parties further agree that none of their respective obligations to one another under the Agreement will be affected by any such blockage except that the party affected by such blockage will be relieved of all obligations to make payments for charges relating to the circuit(s) which is so blocked and that no party will have any obligation to the other party for any claim, judgment or liability resulting from such blockage.

    Remedy Processes

    All claims and rights arising under this Service Level Agreement must be exercised by Customer in writing within thirty (30) days of the event that gave rise to the claim or right.  The Customer must submit the following information to the Customer’s Comcast account representative with any and all claims for credit allowances:  (a) Organization name; (b) Customer account number; and (c) basis of credit allowance claim (including date and time, if applicable).  Comcast will acknowledge and review all claims promptly and will inform the Customer by electronic mail or other correspondence whether a credit allowance will be issued or the claim rejected, with the reasons specified for the rejection.

    Exceptions to Credit Allowances

    A Service Interruption shall not qualify for the remedies set forth herein if such Service Interruption is related to, associated with, or caused by: scheduled maintenance events; Customer actions or inactions; Customer-provided power or equipment; any third party not contracted through Comcast, including, without limitation, Customer’s users, third-party network providers, any power, equipment or services provided by third parties; or an event of force majeure as defined in the Agreement.

    Other Limitations

    The remedies set forth in this Service Level Agreement shall be Customer’s sole and exclusive remedies for any Service Interruption, outage, unavailability, delay, or other degradation, or any Comcast failure to meet the service objectives. 

    C. Threat Management Service Level Agreement

    1. Service Delivery Interval

    For a customer adding TMS to a new EDI service, the TMS service delivery interval will be the same as the EDI service delivery interval. For a customer with existing EDI service, Comcast will configure and activate Customer’s TMS within fourteen (14) business days of submitting the order for TMS.

    2. Protection Interval

    Within receipt of Customer’s notification of suspicious Internet traffic and Comcast’s acceptance of the Sales Order or Customer request, Comcast shall commence On Demand Protection within the above stated Protection Intervals. Upon identification of suspicious Internet traffic by Comcast threat detection platform, Comcast shall commence Automatic Mitigation within the above stated Protection interval. Comcast failure to meet the above requirements shall not constitute a Service Interruption as defined in the Agreement. The SLAs and available credits for EDI Service identified above will not apply during the time period any Comcast-imposed Threat Management countermeasures are in place.

    Customer shall be entitled up to one credit per day and, for any billing month, credits cannot exceed the fifty percent (50%) of the total MRC of the Threat Management Service. 

    In order to receive a credit for Comcast failure to meet the Threat Management SLA detailed above, Customer must open a trouble ticket with Comcast. Customer must request a credit within sixty (60) days following the initial attack event. 

    Disclaimer. When Customer Internet traffic is traversing Comcast mitigation platform, Comcast makes no guarantees that only DDoS attack traffic will be prevented from reaching the Service Location nor that only legitimate traffic will be allowed to reach Customer. Customer acknowledges and agrees that: 

    a. Comcast mitigation constitutes only one component of Customer’s overall security program and is not a comprehensive security solution; and
    b. There is no guarantee that Comcast detection, alerting and/or mitigation will be uninterrupted or error-free.
