SAM2000G-12
12-Port SHDSL Access Multiplexer
Also: SAM2000Q-12 (2B1Q) and SAM2000-12 (CAP)
1.0 SDSL ACCESS MODULE MODELS
SDSL 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 SAM2000G-12
The SAM2000G-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 SAM2000Q-12
The SAM2000Q-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 SAM2000-12
The SAM2000G-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.
