Centre for Health and Policy Studies November 2007research programs between Canada and developing countries. Sailesh has trained inmedicine and public health and until most recently worked as Senior Research Fellow atthe Sree Chitra Tirunal Institute for Medical Sciences and Technology, Trivandrum, Indiawhere he was involved in full time public health research. He is interested in chronicnon-communicable disease epidemiology, particularly risk factors and their modificationwith specific focus on tobacco and hypertension control. Under the mentorship of Drs.Hude Quan and Norm Campbell, he will be examining the epidemiology of hypertensionin Canada and in India and then develop a collaborative research study to beimplemented in India. In addition, he works with the Canadian Hypertension EducationProgram (CHEP) on the Public Education and Surveillance task force groups.Emmanuel Ngwakongnwi, from Cameroon, is a PhD student in the department ofCommunity Health Sciences. He holds an MSc from the University of Ghent, Belgium; aMPH from Lakehead University, Thunder Bay, Ontario. Prior to starting his PhD, heworked as Diversity Educator with the Calgary Health Region,implementing the RegionalDiversity Learning Plan by organizing workshops, conferences and onsite presentations.He is currently working on the following research projects:- Assessing Sex differences in the use of voluntary counselling and testing services forHIV in Cameroon, Africa.- CIHR funding proposal on Official Language Minority Communities- Proposal on Measuring Health Disparities in Canada"Gavin McCormack is a Postdoctoral Research Fellow in the Population HealthIntervention Research Centre, Department of Community Health Sciences. He isworking with Alan Shiell on the EcoEUFORIA project (Economic Evaluation of UsingUrban Form to Increase Activity). This CIHR funded project will investigate therelationship between neighbourhood walkability and physical activity behaviour amongCalgarian adults. Gavin recently achieved a PhD in Public Health (Thesis title: Modellingthe Relationship Between the Built Environment and Psychosocial Correlates of PhysicalActivity Behaviour) from the School of Population, University of Western Australia, andhas completed a MSc in Sports Science (Thesis title: A Comparison betweenConventional and Holistic Exercise Interventions on Physiological Function in theElderly) from Edith Cowan University, Western Australia. In addition to his work on theEcoEUFORIA project Gavin is involved in the surveillance of physical activityparticipation in Western Australia, and is an investigator on a National Health andMedical Research Council (Australia) funded project looking at neighbourhoodwalkability and physical activity among children. Gavin's main research interests includethe determinants of physical activity, physical activity measurement, and healthpromotion.Nicola Main-Thomson is working with Lynn McIntyre as Project Coordinator for theBangladesh Food Provisioning project. She is also doing a follow-up to a Rohingyarefugee study that was conducted in April 2007. Nicola has just completed a 3 yearposting in Bangladesh working for the European Commission Delegation where she wasthe program manager responsible for gender and human rights. These projects andprograms focused on empowering adolescent girls, combating human trafficking,strengthening the police force, providing care for the Rohingya refugees and maintainingservices in the camps, and registering child births nationwide. Prior to Bangladesh,Nicola worked with the European Commission in Brussels as well as with various NGOsin health, human rights, and environment-related projects targeting various countriesthroughout the world.2

Data SheetNETWORK INTERFACE RESILIENCYFlow-based resiliency on uplinks isprovided, as well as G.8031 – Ethernetlinear protection on the network ports.ETX-203A implements EPS Ethernet Pathprotection according to ITU-T G.8031.The device protects one or multiple EVCsin the network via standard APS messagesand via OAM ETH AIS/LOC criteria, ensuringprotection switching under 50 msec. Theprotected EVC runs over one uplink or dualuplinks per customer requirement.Protection is available for the followingtopologies:• End-to-end EPS path protection forone or multiple EVCs transported overMPLS/VPLS access network• Opposite standard PE supportingG.8031 EPS.Additionally, the following protectionmethods are provided via port-basedresiliency on the network ports:• Link aggregation (LAG) based on802.3ad• Dual homing (1:1), allowing ETX-203Ato be connected to two differentupstream devices.COLOR-AWARE P-BIT RE-MARKINGThe VLAN priority bit in Ethernet framescan be modified at network ingressaccording to the ‘color’ of the frame. Thisallows service consistency and QoScontinuity across color-aware (DropEligible-enabled) as well as color-unawarenetworks.FAULT PROPAGATIONThe unit provides a user-configurable faultpropagation mechanism in thenetwork-to-user or user-to-networkdirection. When a link failure is detectedor OAM failure received, ETX-203A canshut down the affected port or forwardthe OAM failure message. The faultpropagation mechanism enables routersand switches connected to both ends ofthe link to reroute the traffic to theredundancy path.INTEGRATED SMART SFP SUPPORTIntegrated management of MiRICi smartSFPs provides TDM (E1/T1/E3/T3/OC-3/STM-1) connectivity over PDH orSDH legacy networks. ETX-203A supportsconfiguration and statistic collection forthe smart SFP TDM port.RFC-2544The device provides a built-in RFC-2544wirespeed traffic generator and analyzerfor unidirectional and bidirectional testingof throughput, latency, and frame loss.The tests are done over any Layer-2,based on standard OAM messages, andcan be performed for multiple flows.LAYER-2/ LAYER-3 LOOPBACK WITHMAC AND IP ADDRESS SWAPPINGAs services and networks become morecomplex, tracking service and networkfaults is very important for conforming tothe SLA. Therefore it is vital that theservice provider can perform networkloopbacks to easily track failures. Layer-2and/or layer-3 network integrity can betested by a non-disruptive loopbackperformed per flow, with swapping ofMAC address and optionally IP address.When the loopback is activated, ETX-203Aexchanges the source and destinationMAC/IP addresses of the incomingpackets. This loopback passes throughEthernet bridges (MAC address) androuters (IP address).Figure 3. Smart SFPs MiRICi-E1T1 and MiRICi-E3T3Figure 4. RAD Ether ASIC Chip

ETX-203ACarrier Ethernet Demarcation DeviceMANAGEMENTThe unit can be managed using thefollowing ports and applications:• Local management via an ASCIIterminal connected to the RS-232 port• Remote inband management via useror network ports routed via separateVLANs, Telnet, or a third-party OSSsystem• Out-of-band management via adedicated management port• SFTP – Secure File Transfer Protocol.TRAP SYNCHRONIZATIONTraps are sent with sequence IDs tonetwork manager groups, to enable themanagers to detect when traps are lostand request the traps be sent again.SECURITYThe following security protocols areprovided by ETX-203A to ensure clientserver communication privacy and correctuser authentication:• SNMPv3• RADIUS (client authentication)• TACACS+• SSH for Secure Shell communicationsession.L2CP HANDLINGETX-203A can be configured to passthrough Layer-2 control frames (includingother vendors’ L2CP frames) across thenetwork, to peer supported protocols(IEEE 802.3-2005 and LACP), or to discardthe L2CP frames.DYING GASPETX-203A reports power failures todefined network management stations bysending an IEEE 802.3-2005 message andtrap, thus enabling the unit to properlydisconnect from the network withnotification of the reason for the serviceproblem.UNIVERSAL POWER SUPPLYThe ETX-203A power supply inlet can beconnected to AC or DC power.DHCPIP address, IP mask, and default gatewaycan be automatically obtained using DHCP.COMMAND LINE INTERFACEDatabases and scripts of commonly usedcommands can be easily created andapplied to multiple units using commandline interface.
