SAM2000GV-12
12-Port VoSHDSL Access Multiplexer
Also: SAM2000QV-12 (2B1Q) and SAM2000V-12 (CAP)
1.0VoSDSL ACCESS MODULE MODELS
VoSDSL access multiplexers are intended for use in Net to Net Technologies' IPD12000 and IPD4000 DSLAMs. Model types vary by the SDSL line code utilized.
1.1SAM2000GV-12
The SAM2000GV-12 operates with Transmission Convergence/Pulse Amplitude Modulation (TC/PAM) line code: a sixteen-level PAM technique which incorporates advanced Trellis code, precoding, spectral shaping, equalization circuits and forward error correction. Otherwise known as G.SHDSL or SHDSL.
1.2SAM2000QV-12
The SAM2000QV-12 operates with Two Binary, One Quaternary (2B1Q) line code: a four-level PAM technique which reduces the signaling rate to half of the bit rate.
1.3SAM2000V-12
The SAM2000V-12 operates with Carrierless Amplitude and Phase (CAP) modulation line code: transmit and receive signals are modulated into two wide-frequency bands that can pass through a filter without being attenuated.
NOTE Throughout this document, "SAM2000GV" is utilized to indicate all three VoSDSL access multiplexer models; information given applies to all three models except as individually stated or otherwise noted.
