SHDTU03b-E1 2/4 Wire G.SHDSL.bis TDM E1 NTU
The SHDTU03b family of G.SHDSL.bis TDM based modems is a telecom product for carriers or SME users. The SHDTU03b-E1 offers an ITU-T G.703 DTE interface which works over an SHDSL interface. The modem supports two different connectors for G.703 E1 application (balanced 120 Ohm RJ45 or unbalanced 75 Ohm dual BNCs) at bit rates from 64kbps to 2.048Mbps. The SHDTU03b-E1 can be configured and managed via EOC, or menu-driven VT100 compatible Async.terminal Interface, either locally or remotely.
Features:
- Supports E1 and fractional E1 over SHDSL
- Standard ITU G.991.2
- Fast and cost-effective services of voice or TDM on a single or two wire pair of existing copper loop infrastructure
- Local management interface with console
- Remote line loopback
- E1 performance monitoring and alarm buffer
- G.SHDSL Line performance monitoring (data rate and SNR)
- Raw and per time interval statistics
- For use in conjunction with BT's EPS8 and EPS9 circuits
