FlexPoint T1/E1 provides a cost-effective solution for extending telecom demarcation points. A pair of FlexPoint T1/E1s are used to extend the demarcation between buildings via fiber. Multimode or single-mode fiber can be used, and fiber links can be extended up to 60km using single-mode fiber.

The FlexPoint T1/E1 is a modular T1/E1 copper-to-fiber media converter that provides reliable and cost-effective extension of devices such as PBXs, CSUs and routers via fiber.

Designed as a transparent repeater, the FlexPoint T1/E1 supports standard T1, E1 and Primary Rate Interface (PRI), voice or data. The converter also supports AMI, B8ZS and HDB3 line codes. Manual switch settings with on-the-label descriptions enable easy configuration of T1/E1 line codes and line lengths.

A crossover switch makes it simple to connect the FlexPoint T1/E1 converter to PBXs or CSUs and eliminates the need for crossover and custom cables to connect devices.

The fiber port operates at 1310nm and supports SC or ST connectors. Multimode fiber models support distances of up to 5km, and single-mode fiber models support distances of up to 60km.

Diagnostic features include local loopback, remote loopback and all 1's insertion (AIS) modes for the copper or fiber segments. Local loopback validates connectivity to local T1/E1 lines, while remote loopback validates the entire fiber segment from one unit without having to make adjustments on both ends. Dry contact relay option allows a separate T1/E1 alarm circuit to be notified when a loss of power is detected.

The FlexPoint T1/E1 features descriptions of the LED indicators on the label for easy in-the-field configuration, installation and maintenance. The LEDs report the availability of power, connection status, diagnostic or loopback modes of operation and the detection of all 1's by the fiber and UTP ports.

FlexPoint modules can be mounted utilizing optional wallmounting hardware or with DIN-rail mounting brackets. They can also be rack-mounted in a 5-Module shelf or in a high-density 14-Module, power-redundant Powered Chassis.

FlexPoint modules installed in the 5-Module shelf or used as standalone devices can be powered by an external AC to DC power adapter, or through the 5VDC chassis connector. Standalone modules can also be powered by attaching an external DC power supply (18-60VDC). When used in the 14-Module power-redundant Powered Chassis with any combination of AC and DC power supplies, the installed modules are powered via the 5VDC chassis connector.

The wide variety of FlexPoint mounting and power options provide flexible upgrade paths as network requirements change and grow.

FlexPoint unmanaged media converters are easy to use and provide dependable fiber connectivity in Enterprise and Government networks around the world.
