IP Service AggregationIf you are currently terminating your growing business IP services using a service edge router outfitted with a channelized DS3, SONET or SDH interface, youunderstand the challenges – these interfaces are expensive, strain the performance of route processors, strand capacity of high performance interface slots,and in many cases are no longer available from the manufacturer. You also understand that life might be simpler if you don’t have to deploy a router in everycolocation facility. With the Overture Networks, you can address all of these challenges and terminate your IP connections at the edge, and use simpleEthernet interfaces on your routers.Products used to deliver this solution, include:ISG 6000Colocation Facility or Point of PresenceDS3/E3ChannelizedDS3/E3OC/STMTDMTransportManaged RouterT1/E1GigENxT1/E1FT1CPE RouterService EdgeRouter2

Mobile BackhaulThe explosive growth of video and data services on mobile devices has created a huge dilemma as mobile operators look to provide them to an expandingbase of subscribers while simultaneously reducing the cost of transporting this increased traffic load. These new services require substantially more networkcapacity than the existing network infrastructure can support. Overture Networks can help network operators and service providers address these concernswith solutions that deliver Ethernet and T1/E1 circuits to the mobile base station and aggregates traffic in the central office or mobile switching center usingoptical Ethernet or the existing TDM infrastructure.Products used to deliver this solution, include:UTS 4000UTX 8500ISG 6000UTX 8214ISG 5100ISG 140/180ISG 34ISG 45ISG 2xTDMServicesCentral Office or Mobile Switching CenterChannnelizedDS3, OC/STMGigEPseudo-wireGatewayGigEOpticalTransportGigEEthernetT1/E1DS3/E3Bonded T1/E1EthernetCarrier EthernetSwitch/RouterGigEChannnelizedDS3, OC/STMTDMTransportEthernet

Native Optical EthernetThe most resilient and scalable way to deliver Ethernet services is directly over optical fiber. But in order to provide a robust and manageable service offeringusing native Ethernet, it is critical to deploy environmentally hardened intelligent edge devices that feature standards-based performance monitoring and faultmanagement as well as features that support class of service, hierarchical QoS and link level redundancy. Overture Networks offers the industry’s mostadvanced line of intelligent optical Ethernet edge devices.Products used to deliver this solution, include:UTS 4000ISG 2xCentral Office or Point of PresenceEthernetGigEOpticalTransportGigEEthernetEthernetCarrier EthernetSwitchGigEEthernet3

Interoffice Ethernet BackhaulIf you need to get Ethernet from one central office or PoP to a colocation facility or remote, you no longer need to wait for dark fiber to become available.Using your existing SONET/SDH, DS3 or T1/E1 infrastructure, you can now transport Ethernet between various points in your network without relying on darkfiber alone. Overture Networks has deployed thousands of devices into this application alone. If you have dark fiber available and wish to manage the endpointsfor performance and fault isolation, Overture Networks products can help there, too.Products used to deliver this solution, include:ISG 6000ISG 5100ISG 2200ISG 140/180ISG 34ISG 45ISG 2xCentral Office or PoPDS3/E3Colocation FacilityEthernetEFM DSLAMColocation FacilityBonded DS3/E3GigEService EdgeRouterOC/STMCore RouterGigEADMOC/STMADMColocation FacilityGigEIP DSLAMOC/STM

T1/E1 (PWE) over EthernetWith the excitement surrounding next generation services such as VoIP, IP video and Carrier Ethernet, it’s easy to see why the workhorses of business access,T1 and E1 circuits, may get overlooked. The reality is that these circuits and services will continue to be needed for many years. Once your Ethernet infrastructureor service is in place, you can provide traditional T1s and E1s with the simple addition of a TDM Pseudo-wire Gateway at each end. If you are concerned aboutbit error rate, jitter, wander, and latency, you can relax knowing that products from Overture Networks deliver pseudo-wires that are indistinguishable fromtheir original circuit switched counterparts.Products used to deliver this solution, include:UTS 4000UTX 8500Central Office or Colocation FacilityPseuedo-wireGatewayGigEGigEOpticalTransportGigEEthernetT1/E1T1s onCh.

ISG 140 AND ISG 180Extending Ethernet services to all customers over readily available T1/E1 facilitiesIt is estimated that only 15% of all US businesses today are reachable via fiber, while the remaining 85%are reachable only by copper (T1 or E1 connections). Therefore, Overture Networks built the ISG 140 andISG 180 to specifically reach off-net customer locations easily and economically using existing T1/E1 lines.The ISG 140 offers highly manageable 10/100 customer access and up to four T1/E1s (eight T1/E1s for theISG 180) for the network connection. These T1/E1s are bonded using standard Generic Framing Protocol(GFP) or Multilink Point-to-Point Protocol (MLPPP), offering up to 12 Mb/s (T1) or 16 Mb/s (E1) of service.Technical Specifications for the ISG 140 and ISG 180Interfaces• 2 x 10/100BaseT ports• 8 x T1/E1 interfaces, supports 1 MLPPPor GFP bundle (ISG 180)• 4 x T1/E1 interfaces, supports 1 MLPPPor GFP bundle (ISG 140)• 1 x 10/100 management portManagement• IP host with DHCP client for automaticaddress assignment• In-band management VLAN• Web-based management interface (GUI)• SNMP agent supporting standard MIBs,including RMON• Syslog• FTP client for download• EdgeAware intelligent management• L2+ Classification• Service OAM: 802.1ag, Y.1731• RADIUSWAN Protocol• RFC1661: Point-to-Point Protocol (PPP)and Link Control Protocol (LCP)• RFC1990: PPP Multilink Protocol (ML-PPP)• RFC3518: Bridging Control Protocol (BCP)• Automatic removal / restoration of failed links• GFP Frame Mapping per G.7041• LCAS per G.7042• VCAT per G.7043Maintenance• T1/E1 loopbacks and PM• Ethernet loopbacks and PM• VLAN loopback• Ethernet cable testing with TDR• Link Quality Monitoring (LQM)Ethernet Services• 802.1p prioritization• 802.1Q VLAN tagging/switching/stacking• Rate limiting: 128-500 kb/s increments• CoS: WRR or strict priority based on VLAN, p-bits or ToS/DSCP• Traffic shapingPower Options• AC Power: 100-240 V auto ranging, 47-63 Hz• DC Power: Dual DC Feeds-48 VDC, nominal (-40 to -60 VDC) or 24 VDCPhysical• 1 RU (1.75” x 17” x 7.25”)• Wall-mount or rack-mount (19” and 23”• Temperature hardened -40° to +65°C (operating)-40°to +70°C (storage)Regulatory• UL/EN 60950• CE Marking• FCC Part 15 Class B• NEBS Level 3 certified• Full frontal access(ETSI form factor)• RoHS compliant
