® OPT-E-MANService 7.Customer Responsibilities In order to deploy OPT-E-MAN service at a customer location, and to successfully transport customer data across the OPT-E-MAN network, the customer will need to adhere to specific guidelines as to the space, power, conduit and other physical aspects of providing the service, and the data formatting and configuration recommendations to ensure maximum Ethernet compatibility with the OPT-E-MAN service. These responsibilities are described in detail in the AT&T Customer Site Preparationand the AT&T Customer Data Format Requirementsdocuments . Both documents are available from anAT&T representative. These requirements, while not specifically part of this service level agreement, describe factors that impact AT&T’sability to meet these service level objectives.These factors include: Traffic Shaping: To ensure maximum throughput efficiency, traffic shaping should be enabled on the customer’s network equipment. When traffic policing is applied on the OPT-E-MAN network, traffic shaping is required in order to ensure that packets are not dropped when entering thenetwork If shaping is not turned on, the OPT-E-MAN network will randomly drop traffic if the customer exceeds the subscribed amount of CIR for that connection. Most routers on the market should support traffic shaping, which makes it easy to implement inits simplest form. OPT-E-MAN offers scalable service connection rates (CIR) from 2Mbps to 1 Gbps, providing great flexibility as long as the customer can shape their traffic. If customers are not able to shape their traffic, they should subscribe to service that aligns with their physical port (i.e. 10/100/1000 Mbps) to ensure maximum throughput. Failure to comply with this recommendation could result in reduced throughput and performance! Switch vs. Router: If the customer uses a router to connect to OPT-E-MAN, only one MAC address is presented to the OPT-E-MAN network. But ifthe customer connects using a bridge or switch for Layer 2 connectivity, a maximum of 50 MAC addresses can be utilized per port. Requests for additional MAC addresses will be with a maximum of 100 MAC addresses total assessed an additional charge, per port. Additional Information 8. For Basic Plus Multipoint configurations, AT&Twill use controls to limit the amount of multicast and broadcast traffic to protect the OPT-E-MAN network against traffic storms. The maximum throughput of multicast traffic will be set at 1 Mbps per customer port, while the maximum throughput of broadcast traffic will be set at 200 packets per second per port. Packets dropped by traffic controls will be excluded from SLA calculations. AT&T recommends that customers enable controls for multicast, broadcast and unknown unicast traffic within the customer network(s). Committed Information Rate (CIR) is inclusive of allowances for overhead within the Ethernet network. If a customer orders 1 Gbps of CIR on a single port, AT&Treserves the right to use up to 10% of the bandwidth for traffic management.
