SDSL Line Code
SDSL Line Code refers to the method of line amplitude modulation for SDSL lines.
SDSL Line Code is currently configurable on SIM2000 interface modules and
SDSL Micro DSLAMs only; it is hard set on all other Net to Net SDSL products.
Additionally, line code applies to ALL ports on SIM2000s and Micro DSLAMs; it
cannot be configured for individual ports.
G.SHDSL (Default)
Transmission Convergence/Pulse Amplitude Modulation (TC/PAM) line code is a
sixteen-level PAM technique which incorporates advanced Trellis code, precoding,
spectral shaping, equalization circuits and forward error correction. Otherwise
known as G.SHDSL.
2B1Q
Two Binary, One Quaternary (2B1Q) line code is a four-level PAM technique which
reduces the signaling rate to half of the bit rate, thereby doubling transmission
efficiency.
CAP
Carrierless Amplitude and Phase (CAP) line code modulates transmit and receive
signals into two wide-frequency bands that can pass throught a filter without being
attenuated.
Speed
The interface module or Micro DSLAM model type will determine the number of
options and individual speeds available for each port. Setting speed to OFF will
disable the port. See individual Interface Module User Guides and Micro DSLAM
