Common use of Access Circuit Clause in Contracts

Access Circuit. The circuit between the Site and the Supplier’s point of presence (PoP”).

Contracted bandwidth represents a bandwidth profile configured on the Ethernet VPN ingress switch port. A single broadcast or multicast ingress frame at a given SAP will be replicated in the Ethernet VPN and a single copy delivered to each of the other SAPs in the EVC. This kind of delivery would also typically apply to a service frame for which the Ethernet VPN has not yet learned an association of the destination MAC address with an EVC/SAP pair. This is an “E-LAN” service as defined by the MEF. Unicast traffic will be point-to-point based on MAC address. The Access Circuit will always be specified as 10, 100 or 1000Mbit/s dependent on the requested EVC data speed across the Ethernet VPN. Capacity across the Ethernet VPN will be between 2 and 1000Mbit/s. The Service comprises one NTU at each Customer Site providing connection to the Supplier Network. The NTUs will be located on the Customer Sites (at the end locations specified in the Order) and the Customer will be presented with either RJ45 copper interface for 10/100Mbit/s service or options of SM or MM on LC fibre connectors, or 1000BaseTx RJ45 copper interface for 1000Mbit/s. The Service demarcation point is the Customer-facing ports of the Customer-sited NTUs. This Service Definition covers Ethernet VPN Circuits at the following speeds: Access Circuit speeds at 10, to 100, to 1000Mbit/s, via Supplier fibre or Short Haul Data Service. EVC bandwidth options are: 2, 4, 6, 8, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 200, 300, 400, 500, 600, 700, 800, 900 and 1000Mbit/s increments (to the limit of the tail capacity and connection speed). The key technical characteristics of the Ethernet VPN circuit are shown below:
