Demarcation Extension Solutions

Extend T1 and Carrier Ethernet Services from the Demarc Point

Riser Management Demarcation ExtensionIn this riser management application, TDM and Ethernet business services are extended to tenants on the upper floors of an office building. Ethernet, T3 and multiple T1s are delivered with UTP copper cables from a Service Provider’s Metro Ethernet or SONET network at the ground floor of the building.

An iConverter 19-Module Chassis is deployed at the demarcation point on the Ground Floor. A GX/TM2 NID plug-in module, a T3/E3 managed media converter and a Modular T1/E1 Multiplexer are installed in the high-density chassis.

Ethernet Service Demarcation Extension

The iConverter GX/TM2 NID module in the 19-Module chassis provides copper-to-fiber conversion, and a managed fiber link to the subscriber’s office on the 10th Floor, where a standalone GX/TM2 hands off the service to a 10/100/1000 copper switch. The GX/TM2 NID modules support IEEE 802.3ah Link OAM for performance monitoring and fault management of the fiber access link. Note that a GM3 NID or GM4 NID can be used to provide Carrier Ethernet Service OAM all the way to the customer hand off.

TDM Service Demarcation Extension

The Service Provider’s T3 circuit is delivered via a CSU/DSU. The T3/E3 coax is converted to fiber with the T3/E3 media converter, and the fiber is run up to the 11th Floor, where a standalone T3/E3 converter provides fiber-to-copper conversion for connectivity to a subscriber’s PBX.

Four T1 circuits are also delivered via a CSU/DSU on the Ground Floor, with four UTP cables connecting to the iConverter Modular T1/E1 MUX. This flexible and scalable system is comprised of an iConverter Fiber Transport module, and one or more iConverter 4xT1/E1 MUX modules installed the chassis. The copper T1s are connected to the RJ-45 ports in the 4xT1/E1 MUX modules, and all the T1s are transported over the fiber port on the Fiber Transport Module.

Note that up to sixteen T1s and Gigabit Ethernet can be transported over fiber with the Modular T1/E1 Multiplexer, and multiple MUX groups can be installed in the same chassis.

The four T1 circuits are transported over the fiber link to the subscriber on the 12th Floor. The fiber is terminated at a fixed configuration iConverter 4xT1/E1 MUX/M that converts the T1s back to native copper RJ-45 interfaces that are connected with UTP cables to a PBX.

Network Management System

Management of the iConverter chassis and modules is achieved with a Network Management Station connected to a Network Management Module (NMM2) installed in the chassis. The Ethernet and T1 services can be managed via SNMP v1/v2c/v3 or TELNET from a management station at the Central Office. The iConverter management system enables monitoring of the Ethernet fiber links in the building, and provisioning of the Ethernet services.

The iConverter management system can be accessed with Omnitron’s NetOutlook® Network Management Software or third-party SNMP management software. GM3 and GM4 NIDs can be managed with NetOutlook EMS.

The iConverter Multi-Service Platform enables service providers and riser management companies to provide reliable fiber connectivity between the Service Provider demarcation point and the subscribers network equipment. The iConverter Multi-Service Platform preserves network hardware investments, and the management system also lowers operating costs by providing fault notification and troubleshooting tools that reduce down-time and trips to tenant equipment.
