TA SOLUTION DESCRIPTION EDA 1200 4.0.
2 Introduction Broadband access is known to be the fastest growing technology in th e telecommunicati ons history. With the EDA broadband access concept, Ericsson has for several years demonstrate d t.
3 EDA 1200 overview The EDA 1200 solution (previously ca lled EDA Box) deploys an access network with switched Ethernet and a number of access drop technologies. Th e following sections describe the compon ents of the EDA 12 00 solution with emphasis on the cornerston e of the system - the IP DSLAM.
4 Solutions with IP DSLAM EDN612 The 12-line IP DSLAM EDN612 is the cornerstone of the new EDA 1200 product line specia lized for VDSL2 rollout with a fallback option for ADSL/ADSL2/ADSL2+. EDN612 is supported by the 12-port Gigabit aggregation switch ESN212; a nd together they form an unmatched scalability and deployment opportuni ty.
5 Solutions with IP DSLAM EDN312 The 12-line IP DSLAM EDN312x is the c ornerstone of the existing EDA 1200 product line (the “blue Box”) and it provides full support for ADSL, ADSL2 and ADSL2+. The 12-line IP DSLAM EDN312x aggre gates all the incoming ADSL links onto one or two 100Base -T Ethernet connections depe nding of the bandwidth demand.
6 Solutions for fiber and Cat5 EFN324 is the cornerstone of Er icsson's fiber access portfolio, targeting residential end-users, small offices/home offices (SOH O), and small to mediu m enterprises (SME).
7 The most significant featu re is the integrated EDA Management Proxy (EMP) functiona lity. EMP enables the Ethernet Controller N ode to reduce management of IP addresses to just on e management IP address per Ethernet Controller Node, indepe ndent of the number of subtended IP DSLAMs.
8 ESN108 is especia lly designed for EDA 1200 series for deployment in areas wi th low subscriber pen etration. The switch ESN108 has a built-in PoE for powering of the IP DSLAM. In conn ect ion with the IP DSLAM EDN312x, ESN108 makes it possible to build small remote sites of up to 96 end-users with 1 Gbps uplink.
9 In this way, there is only one management i nterface and one static IP address. For provisioning, the EMP is managed via standard MIBs, and for system maintenance via EDA SNMP MIBs. All SW images an d configurations are stored i n local non-volatile memory to secure full operati on, even if access to th e management system is unavailable.
10 Traffic mapping End-user traffic is mapp ed to service VLANs. These VLANs may be end-user specific or common to multiple end-users. Through such VL ANs a single or multiple application services, e.
11 ATM-based QoS The ATM-based QoS takes advan tage of the fine- grained segmentation into ATM cells, further minimizing latency and jitter. This ATM-based QoS can be combined with packet-based QoS. In the traditional setup, ther e is a fixed r elation between PVCs and VLANs for traff ic separation.
12 Multicasting EDA supports the increasing demand f or streaming and high quality broadcast vid eo services by offerin g multicast for video streams b oth in the IP D SLAM (using IGMP Snooping) and in the aggregation layer. With Internet Group Mana gement Protocol (IGMP) multicast, parallel transmission of the same video stream is avoided.
13 The following VL ANs are depicted in the figure below, as an example of using VLANs per s ervice: • Voice VLAN for voi ce ToIP service • Video VLAN for video broadcast • Data VLAN for Intern .
14 DSL deployment and maintenance 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 ne twork.
15 It is, of course, also possibl e to use flexibl e topologies when adding VDSL2 to an already existing site with ECN330. With EDA 1200 ther e is always an efficient upgrade path at hand when introducing new technologies and solution s.
16 Mechanical enclosures The EDA solution offers a n umber of mechani cal enclosures for easy an d trouble-free install ation. The enclosures are available in Eur opean and US variants. The US variants inclu de Telco connectors and NEBS approved protection for the ED N312x.
17 288-line subrack The 288-line subrac k is equipped with 24 12-line IP DSLAMs (EDN312x); the height is 11 HU covering up to 288 lines. The subrack include s the 24-port Ethernet Controller Node ECN330. 288-line subrack 1152-line cabinet solutio n This solution consists of an Ericsson BYB501 cabinet.
18 Outdoor cabinet wi th up to 96 subscribers EDA RSC96m The environmental cont rolled cabinet offers a compl ete solution for remote outdoor installatio n of EDA 1200: • 12 to 96 line VDSL2/ADSL2+ .
19 Outdoor cabinet wi th up to 24 subscriber EDA RSC96c The EDA RSC96c is specifical ly designed to h ouse temperature hardened ED A 1200 equipment. It uses direct air cooling in the cabinet instead of m ore traditional heat exch anger unit. Thi s means lower environmental load reg arding noise emission and powe r consumption.
