Deliver Reliable Ethernet Services and Support SLAs

Providing reliable Ethernet services and supporting enforceable SLA assurances requires Operations Administration and Maintenance (OAM) functions to provide fault management and performance monitoring of the entire Ethernet connection. ITU-T Y.1731 and IEEE 802.1ag standards enable End-to-End Service OAM functions to accomplish these service delivery objectives across one or more carrier networks.

802.1ag Connectivity Fault Management improves reliability with OAM tools for instant fault notification and rapid fault isolation. Y.1731 monitors the performance of Ethernet services on both an EVC and Class of Service basis for Service Level Agreement (SLA) assurance.

Expand the Capacity of Metropolitan, Access and Backhaul Fiber Links

Coarse Wavelength Division Multiplexing (CWDM) increases the capacity of SONET/SDH, metropolitan, first-mile access, mobile backhaul and hybrid coax/fiber networks to enable new services and revenues. Each CWDM wavelength is an independent data channel that can transport a different protocol (Ethernet, TDM, etc.) and data rate (up to 10 gigabits each).

• Co-locate more Service Providers at cellular towers
• Overlay Ethernet and TDM circuits onto SONET rings
• Add new subscribers to fiber access networks and hybrid coax/fiber networks

iConverter CWDM/X and CWDM/AD Add+Drop MUX products multiplex up to sixteen independent wavelengths over single mode fiber.

iConverter CWDM modules utilize a small and scalable plug-in form factor, and can be installed in any powered or unpowered iConverter chassis achieving some of the highest port densities in the industry. iConverter CWDM modules are available in expandable four-channel and eight-channel configurations.

The modules are designed to be integrated with other iConverter media converters and transponders to provide a true multi-service platform capable of delivering Ethernet, TDM, SONET and other services across a CWDM common link.

Migration to LTE Ethernet Backhaul

The proliferation of mobile devices is driving a seemingly insatiable need for mobile backhaul bandwidth. Fiber is the only media capable of supporting virtually limitless growth, so Carriers are currently driving fiber to the edges of the network. Unfortunately, bandwidth is only part of the problem. Mobile technology is in the midst of a migration from third generation (3G) to fourth generation (4G/LTE). This means that Carriers providing backhaul must be able to satisfy growing demands for TDM services while preparing for a seamless migration to all Ethernet network in the future. While many options are available, Carriers must be able to support the migration in a scalable and cost-effective manner.

Omnitron Ethernet Network Interface Devices, T1/E1 multiplexers, CWDM Multiplexers and media converters provide transport of both TDM and Ethernet services in this migration from TDM to LTE backhaul. In addition, they support the ability to connect multiple carriers to the cell tower for wholesale mobile backhaul.

There are essentially three phases in the migration from legacy 3G to LTE mobile backhaul. Omnitron fiber connectivity products can support backhaul of services at each phase.

1. Legacy mobile backhaul networks are based on TDM
2. Current migration adds Carrier Ethernet to TDM network (Hybrid Mobile Backhaul)
3. The future requires Long Term Evolution (LTE) Carrier Ethernet and fiber infrastructure

iConverter Fiber Connectivity Solutions Enable this Migration

1. iConverter T1/E1 Multiplexers transport up to sixteen T1 circuits over fiber for Legacy TDM backhaul
   • Local and Remote Loop-back for troubleshooting and installation verification
   • Supports AIS (Alarm Indication Signal) generation on each T1/E1
   • Management via local serial port, Telnet or SNMP

2. iConverter T1/E1 Multiplexers transport 10/100/1000 Ethernet with the T1s for hybrid mobile backhaul
   • Same form factor and functions, and adds 10/100/1000 Ethernet multiplexed with the T1s
   • Enables hybrid Ethernet/TDM mobile backhaul

3. iConverter GM3 Network Interface Devices support Service OAM to enable Carrier Ethernet / LTE backhaul
   • Supports 802.1ag Connectivity Fault Detection and ITU Y.1731 Performance Monitoring
   • Service multiplexing and traffic shaping
   • Remote management through TELNET, SNMPv1/2c/3
