Carrier Ethernet in the Access, Metro & Global Networks
Carrier Ethernet Services operate independently ofthe physical networks they run across makingexpansion to new technologies easy
Creates a single service connection from Enterprise
or business office, in a single person office, or homeor on the road. In the Metro and First Mile, Ethernet is becoming the
network of choice with migration from Frame Services

Delivering Ubiquitous Ethernet Services- The Access Network Challenge
Ethernet over Fiber (EoF) access networks The optimal technology for delivery of Ethernet services
Unfortunately, not all Enterprise sites have fiber accessHowever, they all have access to copper/PDH circuits
How does a service provider deliverEthernet services to all Enterprise locations?

What is Ethernet over PDH (EoPDH)?
Technology that enables delivery of Ethernet servicesover PDH (E1/DS1, E3/DS3) access networks
Service Bandwidth Granularity N x 2Mbps (N bonded E1s), N x 1.5Mbps (N bonded DS1s) N x 32Mbps (N bonded E3s), N x 45Mbps (N bonded DS3s)
Example: 5 bonded E1s provide a 10Mbps Ethernet service Supports same MEF service attributes as EoF services
Ethernet UNI to subscriber Granular bandwidth and QoS per service Fault Management and Performance Management for SLAs
PDH (Plesiochronous Digital Hierarchy): Term to collectively refer to E1/E3 and DS1/DS3 copper access network circ
EoPDH enables a common Ethernet service offeringand SLA over both copper and fiber access networks
8/13/2019 MEF Presentation
11/4011
How does EoPDH work?
Ethernet Frames enter UNI on EoPDH CLE and encapsulated in GFP Access Network multiplexes E1s into channelized STM-1 circuits
E1s in STM-1 circuits terminated on EoPDH Aggregator GFP terminated, Ethernet frames reconstructed
EoPDH Aggregator adds S-VLAN tag (QinQ) and passes EthernetService Frames to Ethernet Transport Network

What about OPEX?
Issue Point-to-Point PON
Resource planning in access /engineering rules
Simple: dedicated fiber Complex: shared medium,subscribers mutuallydependent, # of customers ontree varies
Fiber troubleshooting Simple: failure uniquelylocated through reflectionmeasurements
Complex: location of failurebehind splitter difficult toidentify
Encryption key management Not needed RequiredBandwidth / technologyupgrade
Simple: can be done on a per-customer basis
Complex: replacement of allactive equipment at once orwavelength overlay
Connecting a new subscriber Patch at ODF and config ofswitch, compensated byinitial capex savings
Config of OLT
Outage after cable break Longer in the feeder part(more fibers to splice),shorter in the drop part(easier diagnostics)

The results [of the research evaluating thesustainability and environmental impact of fibernetworks] clearly demonstrate the overall service andenvironmental benefits of FTTH. The findings stand astestament that fiber is a sustainable and future-prooftechnology for the 21st century.Jo eri Van B og aert , presid ent FTTH Coun cil , 2008
Fiber right now is not just a means to get bits to the subscriber, it is also a potentially effective marketing tool. Telecom Strategy Partners, 2008

PON is becoming a leading fibre technology
GPON will dominate in the US, since it isnow certain to be used by both the majorILECs and many independent telcos. ActiveEthernet has some limited support in theUS, but it will remain a minority technology,taking declining share in the overall marketFTTH Worldwide technology update & market forecast
Because GE-PON is currently thetechnology of choice in Japan,
it will dominate overall global FTTHdeployments over next few years.FTTH Worldwide technology update & marketforecast

What is PON?
Created by the FSAN organization (driven by service providers & operators);Standardized by ITU-T (A/BPON, GPON) or IEEE (EPON)
Bandwidth >100Mbit/s per subscriber through DBA PON optimized for multicast and downstream intensive traffic
Cost-optimized support of multiple (legacy and new) services through various subscriberinterfaces: VoIP (SIP, H.248), video (IPTV, cable TV), data Support of all types on in-house cabling: copper TP, CAT5, fiber Real multi-service platform: in the 1st mile and in the CO Easy upgrade to more subscribers and higher bandwidth Clear migration path to NG-PON PON is a green technology
