1.0   VoSDSL 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. 
 
 
1.1   SAM2000GV-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. 
 
 
1.2   SAM2000QV-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. 
 
 
1.3   SAM2000V-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.
