Giới thiệu
AN-GSHDSL-E1 modems use TC PAM-16 line coding, equalization, adaptive filtering and echo cancellation to compensate for line impairments, bridge taps and mixed cabling. This provides immunity to background noise and enables transmission of multiple SHDSL lines on the same physical cable. AN-GSHDSL-E1 can be managed via A VT-100 compatible Asynchronous Terminal Interface.
AN-GSHDSL-E1 is equipped with an adaptive auto rate capability that identifies the maximum line rate supported by the copper loop.
Đặc trưng
- Extends the range of 2Mbps data transmission up to 4Km
- Supports both E1 G.703 modes – framed E1 (fractional) and unframed
- Supports all industry standards, and made especially to work with other third party vendors TDM equipment, what supports G.SHDSL standard
- Monitoring, control and diagnostics of local and remote units are made by Network Management System
- Perfomance monitoring available on console management
- Robust, error free transmission algorithm used
- Remote and local loopbacks for testing purposes
- Industries probably most effiecient TC PAM-16 line coding for effective twisted pair usage and high distances
