Product Summary

The ACE-2002 multiservice ATM access unit and ACE-2002E multiservice ATM access unit are fully modular access concentrators that can be used as carrier-owned demarcation devices or as a corporate concentrator connected to the public ATM network. The ACE-2002 multiservice ATM access unit and ACE-2002E multiservice ATM access are designed to deliver LAN, voice and data services over existing ATM access networks. Having a clear demarcation point at the customer premises increases service reliability, improves network efficiency and ensures end-to-end Quality of Service (QoS) support.

Benefits:

• Allows service providers to offer LAN, Frame Relay, ATM, and voice/TDM services over ATM networks or terminate ATM services • Extends QoS to the customer premises enabling service legal agreements • Improves diagnostics and system performance monitoring • Increases service flexibility and reliability • Allows multiple traffic management options, including traffic monitoring, policing and shaping • Strong network management capabilities reduce operating costs • Fault isolation enhance reliability • Plug-and-play installation reduces operating costs

Further Product Information

The ACE-2002 multiservice ATM access unit can be used as a carrier-owned demarcation device or as a corporate concentrator connected to the public ATM network. The ACE-2002E multiservice ATM access unit is an enhanced version of the ACE-2002 multiservice ATM access unit that can accommodate additional E1/T1 interfaces. Information about ACE-2002 multiservice ATM access unit also pertains to ACE-2002E multiservice ATM access unit unless otherwise specified. As a demarcation device, the ACE-2002 multiservice ATM access unit enables carriers and service providers to define the boundary between their ATM-based public services and the customer private network (customer-located equipment - CLE). A clear demarcation point at the customer premises increases service reliability, improves network efficiency and ensures end-to-end QoS support. The ACE-2002 multiservice ATM access unit can be used for a combination of legacy services such as voice, LAN, HDLC, and ATM, or as a demarcation device for native ATM traffic. The ACE-2002 multiservice ATM access unit has built-in features that enable the extension of ATM network facilities up to the customer premises. These features support various ATM services, such as advanced traffic management (policing, scheduling and shaping) and full I.610 OAM (Operation, Administration and Maintenance) flow support. In addition, the wide range of ATM modules further enhances the flexibility of service offerings. When used as an interworking device, the ACE-2002 multiservice ATM access unit enables smooth migration of legacy equipment such as PBXs and routers operating over ATM networks. Using multiport modules and three user slots, the ACE-2002 multiservice ATM access unit can be used as a concentrator for medium to large corporations. The unit enables the most efficient utilization of public ATM services for transporting different types of corporate traffic, including ATM. ACE-2002 multiservice ATM access unit supports both NNI and UNI addressing with full bit range of VPI/VCI fields. ACE-2002 Multiservice ATM Access Unit can support up to 1,024 connections (VPC and/or VCC). In addition, full switching capability is available between each VC or VP (from either the user or the network) to obtain maximum flexibility in connection assignment. To enhance carriers' service offerings, ACE-2002 multiservice ATM access unit supports VP tunneling. This enables bundling multiple VCCs into a single VPC while maintaining all the VCC QoS characteristics and I.610 OAM capabilities at F4 and F5 layers. Each tunnel can be shaped as a CBR connection. It can be defined with end-to-end OAM flows and act as a regular VP connection in the public network.

Traffic Management

Both users and network operators benefit from spacing bursty traffic. For the user, more traffic can pass through the link at no additional cost. For the operator, spacing enables better statistical efficiency while keeping the same backbone equipment and QoS. ACE-2002 Multiservice ATM Access Unit offers a built-in mechanism that supports up to 983 spaced connections. In addition, ACE-2002 multiservice ATM access unit supports hierarchical traffic scheduling. The layers are set per VC, per VP or VP tunnel and per network interface. In these cases, ACE-2002 Multiservice ATM Access Unit schedules the traffic to meet pre-defined traffic parameters. This ensures fair bandwidth sharing between different connections while preserving the requirements of the individual connections. In order to improve service resilience, ACE-2002 multiservice ATM access unit offers a protection mechanism on the user and network sides, which enables standard SDH/SONET protection of the last physical segment from the service exchange to the customer premises. ACE-2002E multiservice ATM access unit can combine up to 20 E1/T1 IMA/UNI ports, or up to 20 E1/T1 CES ports. The high E1/T1 port density is especially suitable for cellular applications. ACE-2002 multiservice ATM access unit can be equipped with multiple LAN modules (up to six LAN ports in the ACE-2002E). The LAN module performs bridging and routing (RFC 1483/2684) with IP ToS and 802.1D priority support. In addition, multiple VLANs can be configured, optimizing ACE-2002 Multiservice ATM Access Unit for LAN and IP access applications. The ACE-2002 multiservice ATM access unit comes in a 1U high enclosure suitable for mounting in a 19" rack. The ACE-2002E multiservice ATM access unit is 1.5U high
