RAD ACE-52 Multiservice Network Termination Unit
ATM Termination Network Unit
Multi-service Access Concentrator
ATM Demarcation Device or Enterprise Access Concentrator
Maximizes revenues by running
additional services on the existing ATM infrastructure
revenue streams with transparent LAN services over ATM.
Service 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 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 provides L2 VPN service. Using VLAN tagging, the ACE-52 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., date, voice, video). Optionally, a different priority can be defined for different types of traffic within each VPN by mapping VLAN priority to different VCs with appropriate QoS parameters.ACE-52 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 Control
The low cost ACE-52 NTU serves as a demarcation device that is owned and managed by the service provider and installed at the customer premises. ACE-52 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 Opex
ATM OAM functionality supported by ACE-52
helps reduce operational costs by providing end-to-end traffic manageability
and fault localization.
The ACE-52 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
five different service classes: CBR, VBR,GFR 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.
Management Eases Installation and Minimizes System Downtime
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. Related Links
