SOLUTION DESCRIPTION EDA 1200 4.
Introduction Main features Broadband access is known to be the fastest growing technology in the telecommunications history.
EDA 1200 overview IP DSLAM with high functionality The EDA 1200 solution (previously called EDA Box) deploys an access network with switched Ethernet and a number of access drop technologies. The following sections describe the components of the EDA 1200 solution with emphasis on the cornerstone of the system - the IP DSLAM. The EDA 1200 IP DSLAM is available as a complete allin-one system with a unique scalability from 12 to 288 lines. The IP DSLAM is built on Ethernet technology (TR-101).
Solutions with IP DSLAM EDN612 POTS and ISDN services For the support of underlying telephony services POTS and ISDN a external splitter solution is available as well, compliant to the EDA installation method. The 12-line IP DSLAM EDN612 is the cornerstone of the new EDA 1200 product line specialized for VDSL2 rollout with a fallback option for ADSL/ADSL2/ADSL2+.
Solutions with IP DSLAM EDN312 The scalable IP DSLAM concept is built from a combination of the 12-line IP DSLAMs and the Ethernet Controller Nodes — with the possibility of using the 8port switch ESN108 for aggregation in between. The 12-line IP DSLAM EDN312x is the cornerstone of the existing EDA 1200 product line (the “blue Box”) and it provides full support for ADSL, ADSL2 and ADSL2+.
Solutions for fiber and Cat5 Controller Nodes and Ethernet switches EFN324 is the cornerstone of Ericsson's fiber access portfolio, targeting residential end-users, small offices/home offices (SOHO), and small to medium enterprises (SME). The EDA solution offers a unique suite of 1st and 2nd level Ethernet aggregation switches and Controller Nodes. The Ethernet Controller Nodes are equipped with EDA Management Proxy (EMP) for local management of subtended nodes.
Aggregation Ethernet switch ESN212 The most significant feature is the integrated EDA Management Proxy (EMP) functionality. EMP enables the Ethernet Controller Node to reduce management of IP addresses to just one management IP address per Ethernet Controller Node, independent of the number of subtended IP DSLAMs. Ethernet Controller Node ECN330 is a natural aggregation point for the EDA 1200 series of IP DSLAMs based on EDN312x, as it contains 24 100 Mbps Fast Ethernet downlink ports.
Management ESN108 is especially designed for EDA 1200 series for deployment in areas with low subscriber penetration. The switch ESN108 has a built-in PoE for powering of the IP DSLAM. In connection with the IP DSLAM EDN312x, ESN108 makes it possible to build small remote sites of up to 96 end-users with 1 Gbps uplink. ESN108 can be installed directly on a LSA® PROFIL or U-shaped back mount frame.
The flexible topology support is particularly powerful for VDSL2 deployment in scenarios where telecom operators already have access aggregation switches in place, with non-Ericsson equipment. In this way, there is only one management interface and one static IP address. For provisioning, the EMP is managed via standard MIBs, and for system maintenance via EDA SNMP MIBs.
Traffic mapping PTM for VDSL2 - Principles With VDLS2 on the EDN612 Packet Transmission Mode (PTM) is introduced instead of ATM. In short, PTM allows direct transmission of Ethernet packets on the DSL line, by segmenting the line capacity into two latency paths — a fast path and an interleaved path. The two paths are individually configured and will typically be utilized for separation of different types of services. End-user traffic is mapped to service VLANs.
ATM-based QoS QoS within single PVC (EDN312) The ATM-based QoS takes advantage of the finegrained segmentation into ATM cells, further minimizing latency and jitter. This ATM-based QoS can be combined with packet-based QoS. The IP DSLAM also supports multiple traffic classes (services) within the PVC, allowing the access provider to support multiple services from a single gateway.
Multicasting communicate with End-user (2) within the same VLAN, will issue an ARP request to get the destination MAC address. However, the ARP proxy will respond to the ARP request with the MAC address of the default gateway instead of the MAC address of End-user (2). In this way, the requesting End-user (1) will now send traffic via the default gateway, assuming that it is in fact End-user (2).
profiles, end-user provisioning is easily created by choosing the desired template. The following VLANs are depicted in the figure below, as an example of using VLANs per service: • Voice VLAN for voice ToIP service • Video VLAN for video broadcast • Data VLAN for Internet access service • Management VLAN used for all O&M Profiles can also be incorporated within the Access Node.
DSL deployment and maintenance Network migration Operators can save investments by building on existing solutions — both in the access area as well as for the network infrastructure. EDA supports VDSL2 ITU 993.2, ADSL2+ ITU G.992.5, ADSL2 ITU G.992.3 and ADSL ITU G.992.1. VDSL2 opens for up to 100/50 Mbps downstream/upstream bandwidth that enables the possibility for bandwidth demanding services in the network. ADSL2+ also offers high bandwidth of up to 24 Mbps downstream.
Transport It is, of course, also possible to use flexible topologies when adding VDSL2 to an already existing site with ECN330. With EDA 1200 there is always an efficient upgrade path at hand when introducing new technologies and solutions. Ethernet over SDH Operators with an Ethernet-based core network might still have an existing Sonet/SDH-based infrastructure, mostly to small and rural sites where the penetration of bandwidth demanding services is not yet high.
Mechanical enclosures The EDA solution offers a number of mechanical enclosures for easy and trouble-free installation. The enclosures are available in European and US variants. The US variants include Telco connectors and NEBS approved protection for the EDN312x.
288-line subrack Outdoor enclosure The 288-line subrack is equipped with 24 12-line IP DSLAMs (EDN312x); the height is 11 HU covering up to 288 lines. The subrack includes the 24-port Ethernet Controller Node ECN330. The EDA 1200 solution is perfectly suited for outdoor installation, due to its environmentally hardened nature and unique scalability. Environmental characteristics EDA 1200 based on EDN612/ESN212/EPN210 are designed to meet ETSI EN 300 019-1-3 class 3.
