OA 1431

1431 Router Series SHDSL CPE

The 1431 SHDSL CPE uses the state-of-the-art SHDSL modulation to deliver Leased Line, Frame Relay and ATM services over an ATM based DSLAM access network.

Features and benefits


For this purpose the unit can accept an exchangeable serial or G.703 interface. The equipment additionally features a fixed Ethernet auto-sense 10/100 Base-T connection for the delivery of professional IP services. The 1431 SHDSL uses symmetrical full-duplex transmission up to 2.3 or 4.6 Mbps over a single or dual two-wire unconditioned unshielded twisted-pair cable.

The Frame Relay service is encapsulated in ATM using the Frame Relay forum recommendations FRF 5 or FRF 8. The leased line service is emulated using the ATM CES (Circuit Emulation Service). The ATM Service delivery on E1 (.703) is accomplished according to the ITU-T standard I 432.3. As a result, the equipment enables service providers to deliver professional Frame Relay, Clear channel, and ATM services based on a standard ATM DSLAM based network.


Fully supported by the TDRE (Total Dynamic Routing Engine), the unit supports also differentiated IP services including VPNs (Virtual Private Networks) and the delivery of application dependent QoS (Quality of Service) connections.
