Product SummaryRAD's ACE-52 multiservice network termination unit is competitively priced customer located equipment (CLE) for provisioning Ethernet and E1/T1 services over an ATM network. Supporting one or two 10/100BaseT ports and one optional E1/T1 CES port, the ACE-52 multiservice network termination unit provides a demarcation point between the provider's network and the customer premises. End-to-end traffic and network management and control enable the carrier to ensure Quality of Service and Service Level Agreement. Benefits• Carriers can use existing ATM infrastructure to provide lucrative transparent LAN services and Layer 2 VPNs• Cost effective demarcation device with end-to-end QoS for SLA enforcement Further Product InformationThe low cost ACE-52 multiservice network termination unit allows service providers to take advantage of their existing ATM infrastructure for providing transparent LAN services, as well as integrated voice and data services, over the ATM network. Services are enhanced by ATM's high capacity, reliability and Quality of Service (QoS) capabilities. Multiple services over ATMService providers are looking for ways to cost-effectively run more services over their ATM backbones, to leverage their widespread deployment of ATM. RAD's ACE-52 multiservice network termination unit is ideal for transporting transparent LAN services (TLS) over the ATM network, since it allows both transparent LAN bridging and VLAN bridging in point-to-point or point-to-multipoint topology. In addition to its attractive price, the ACE-52 multiservice network termination unit provides L2 VPN service. Using VLAN tagging, the ACE-52 multiservice network termination unit achieves total traffic separation between customers by assigning VLAN IDs to virtual connections (VCs), creating a Layer 2 virtual private network (VPN) for each customer or service (e.g., data, voice, video). Optionally, a different priority can be defined for different types of traffic within each VPN by classification based on the IP TOS or 802.1p values of the Ethernet traffic. ACE-52 multiservice network termination unit supports voice and other TDM services over ATM through an E1/T1 circuit emulation service (CES) port, which enables users to connect their PBX or any other TDM device to the ACE-52 and extend circuits over the public ATM network. This feature supports structured or unstructured services with or without CAS. The CES port synchronized with the ACE-52 ensures clock synchronization over the ATM network. Intelligent demarcation ensures end-to-end controlThe low cost ACE-52 multiservice network termination unit serves as a demarcation device that is owned and managed by the service provider and installed at the customer premises. ACE-52 multiservice network termination unit monitors and controls traffic entering and exiting the network, enabling the service provider to maintain QoS commitments to all its customers end-to-end. OAM functionality reduces OpexATM OAM functionality supported by ACE-52 multiservice network termination unit helps reduce operational costs by providing end-to-end traffic manageability and fault localization. OAM functionality complies with ITU-T I.610 and includes the following: • AIS/RDI - system indication for fault conditions in the network. In case these indications are detected in the network interface, ACE-52 sends a trap to alert the management system. • Continuity Check (CC) - this OAM type is used to check service availability. ACE-52 sends a CC cell periodically over a predefined VCC and verifies that the link is intact. • Loopback (LB) - LB functions can be used for fault localization. The LB cell can be sent with a destination address and may be looped at any network element that was pre-assigned with a loopback point address. Offer differentiated servicesThe ACE-52 multiservice network termination unit lets the service provider assign QoS parameters per virtual connection (VC), enabling it to generate additional revenue by offering different levels of service. ACE-52 supports four different service classes: CBR, VBR, UBR and UBR+. The ACE-52 assures that the guaranteed data rate of each VC is granted, and that the maximum data rate of each VC is not exceeded. Sophisticated traffic management capabilities, such as traffic shaping and monitoring, help carriers avoid congestion and anticipate problems before they affect the service. They also make sure that users do not exceed their allocated bandwidth, while increased statistical efficiency allows the customer to pass more traffic over the link when the network is free. Remote management eases installation and minimizes system downtimePlug-and-play installation, automatic IP address learning and remote configuration simplify ACE-52 deployment. The device can be managed by the RADview HP OpenView application running on a UNIX or PC platform, which provides the capability to monitor, configure, isolate faults, and present network statistics on a graphical, user-friendly display. Configuration can be remotely downloaded/uploaded to/from the ACE-52. CORBA interface facilitates easy integration with third-party network management systems.
