Specifications include, but are not limited to: 4.2 Service Availability Bidder Ethernet service must be available twenty-four (24) hours per day, three hundred sixty five (365) calendar days per year. 4.3 Service Reliability Bidder service must be available at specified performance for a minimum 99.9 percent of the time during each calendar month. 4.4 Service Performance Purchaser is entitled to receive from Bidder the agreed upon bandwidth capacity or better 24 hours per day, 7 days per week for the duration of the service term. For example, if OFM contracts with Bidder for a 100Mbps circuit between two of OFM’s endpoints then OFM will always have 100Mbps of capacity available for OFM’s sole use between those endpoints. Bidder may oversubscribe their networks as long as OFM packets are not dropped when overall OFM use is within the purchased guaranteed bandwidth profile. 4.5 Frame Delay (Latency) The Bidder ten (10) minute average One-way Frame Delay, as defined by the MEF standards in MEF 10.3, should be < 15 ms. One-way is defined as “the time required to transmit a Service Frame from the ingress UNI to the egress UNI.” 4.6 Frame Loss Ratio & Availability (Packet Loss) Bidder ten (10) minute average One-way Frame Loss Ratio, as defined by the MEF standards in MEF 10.3, must be < .01%. One-way Frame Loss Ratio is defined as “the measure of the number of lost frames between the ingress UNI and the egress UNI.” 4.7 Inter-Frame Delay Variation (Jitter) The ten (10) minute average for Inter-Frame Delay Variation of the Bidder’s service, as defined by the MEF standards in MEF 10.3, must not exceed 50% of the Frame Delay as defined in Section 4.5. Inter-Frame Delay Variation is defined as “the difference between the one-way delays of a pair of selected Service Frames.” 4.8 Protocols Bidder shall not impede the passing of any protocol Frames on the Ethernet Virtual Connection (EVC) for the specific type of service (EPL, EVPL, etc…) whilst adhering to the standards set forth in MEF 6 which specifically addresses L2CP protocols. Any impediment or modification of protocol frames not specified by the MEF standards will constitute a service outage. This shall include, but not be limited to, topology discovery protocols, routing protocols, multicast protocols, streaming protocols, and voice protocols. 4.9 Maximum Transmission Unit (MTU) Bidder shall allow the OFM to be able to transmit up to 9000 byte frames on 1G and higher links (not inclusive of Link Aggregation Group – LAG – links, unless one of the subtended circuits on the LAG is of 1G or higher bandwidth). The Bidder shall allow the use of 1500 byte frames on all Ethernet transport circuits. 4.10 Out of Service Definition Bidder must accept the definition of “out of service” as the inability to reliably pass data at the purchased rate on any Bidder-managed transport path due to excessive latency, errors, loss or violations as defined in Section 4 – Ethernet Performance Requirements. 4.11 Service Interface and Termination Requirements Unless otherwise specified by Purchaser, the interfaces provided to Purchaser locations must be administratively configured for use as a full duplex interface per the resulting Work Order or site agreement as defined below. Handoff of 1,000Mbps (1Gbps) or less shall have a 1000BASE-T RJ-45 copper handoff, also referred to as 802.3ab Handoff greater than 1,000Mbps (1Gbps) and less than or equal to 10,000Mbps (10Gbps) shall have a 10GBASE-LR LC Single Mode duplex fiber handoff, also referred to as 802.3ae Handoff of 100,000Mbps (100Gbps) shall have a 100GBASE-LR4 LC Single Mode fiber handoff, also referred to as 802.3ba Bidder is responsible for all access and fiber/cabling to the point of service handoff at the customer premise equipment (switch, router, or other point, as defined by Purchaser)
