SAM2000GV-12
12-Port VoSHDSL Access Multiplexer
Also: SAM2000QV-12 (2B1Q) and SAM2000V-12 (CAP)
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.
