S-RPT/EFM is a compact 2/4-wire SHDSL/SHDSL.bis repeater, extending the range of data transmission over
SHDSL/SHDSL.bis infrastructure. S-RPT/EFM can be chained to increase the transmission range.
Based on the latest DSL technology, S-RPT/EFM provides superior distance and speed using TC-PAM 16/32 encoding, which offers a narrower power spectrum than 2B1Q and other technologies.
