Furthermore, it operates in IDSL mode for – IDSL (ANSI T1.
601) interoperability with Basic Rate ISDN repeaters.
The ZipWireMulti also supports – Proprietary/Extended Reach Conexant’s own proprietary modes, such as 32-PAM, 64 kbps, and 3.
088 Mbps (ANSI spectrum management for operation, which provide enhanced spectral compatibility, extended subscriber line loop transmission systems) reach, and high-speed operation.
All these modes are supported by a single hardware – Proprietary/high-speed (ANSI circuit (i.
e.
, one transformer, crystal, and hybrid for all modes) and can be configured in spectrum management for loop realtime via software control.
