G.SHDSL and G.SHDSL.bis modems

It is a cost-effective high-speed modem, up to 4608 kbps. It operates at N x 64 kbps, 3<=N<=72 when operating over 4-wires and 3<=N<=36 when operating over 2-wires. It is fully complies with G.SHDSL/ G.SHDSL.bis, ITU-T G.991.2 recommendation, which is the most recent, highest performance standard in the market today. TC-PAM type coding ensures spectral compatibility with other type of services like HDSL and ADSL with provides ranges 15 to 20% higher compared with modems utilizing 2B1Q modulation.

Diagnostic capabilities include user-activated local loop backs; BERT tester can be activated and detected.
