Ethernet and TDM Hi-Rise Demarcation Extension

iConverter Network Interface Devices (NIDs) and managed media converters enable fiber connectivity between service provider equipment and subscribers in high-rise buildings.

In this application example, Ethernet business services and TDM services (T1 or T3) are delivered via fiber links to subscribers in the building.

On the Ground floor of the building, demarcation equipment owned by the service provider is connected to a Metro Area Network (Ethernet and/or SONET). The service provider’s UTP Ethernet switch is connected to iConverter 10/100M2 media converters installed in an 19-Module Chassis. UTP from the service provider equipment is converted to fiber by the managed Ethernet 10/100 media converters.

The service provider’s T1 circuits are delivered via a CSU/DSU, and the T1 UTP is converted to fiber with iConverter T1/E1 media converters installed in the same 19-Module Chassis. The iConverter chassis and modules are managed with a Network Management Station connected to a Network Management Module (NMM2) in the chassis.

On the 10th floor, the fiber delivers T1 service to a subscriber. An iConverter T1/E1 media converter installed in a 1-Module Chassis converts the fiber to UTP and connects to subscriber’s PBX.

On the 11th floor, the fiber delivers Gigabit Ethernet service. A standalone iConverter GX/TM2 NID with integrated management converts the fiber uplink to UTP that is connected to the subscriber’s Ethernet switch.

On the 12th floor, the fiber delivers 10/100 Ethernet service. The fiber connects to an iConverter 2-Module Chassis with a 10/100M2 plug-in module and a four port 4Tx VT 10/100 switch module installed in the chassis. The two modules share data via the chassis backplane to provide a fiber uplink and a 5-port managed VLAN department switch. This compact switch connects directly to the subscriber’s switch equipment.

The Ethernet services can be managed from a remote location, such as a Central Office. Management can also be accessed in the building from the Network Management Station via serial or Ethernet connection to the NMM2. The iConverter management system enables monitoring of the Ethernet fiber links in the building, provisioning of the Ethernet services, and remote configuration of the iConverter equipment at the Subscriber Premises. The T1/E1 module in the 19-Module chassis is managed by the Network Management Station and provides fault detection of the fiber link and loopback testing of the remote unit.

The iConverter management system can be accessed with Omnitron’s NetOutlook® Network Management Software or third-party SNMP management software.

The iConverter multi-service platform enables reliable fiber connectivity between service provider UTP equipment and subscriber UTP equipment, preserving network hardware investments. The iConverter management system lowers operating costs by providing fault notification and troubleshooting tools that reduce down-time and trips to subscriber equipment.
