Stanby Mode
Only one of two pairs are working, other pair is standby. If the working pair fails, the standby pair
will start up to continues.
Multi–Link Mode
For 4-wires model, each pair will connect to two different remote device, which may or may not be
in the same location. Channel A used as CO side and Channel B used as CPE side.

TCPAM stands for Trellis Coded Pulse Amplitude Modulation. It is the modulation format that is
used in both HDSL2 and SHDSL, and provides robust performance over a variety of loop
conditions. SHDSL.bis supports 16 level TCPAM line code(TPCAM-16) or 32 level TCPAM line
code(TCPAM-32) to provide a rate/reach adaptive capability, offering enhanced performance
(increased rate or reach) and improved spectral compatibility. The default option is Auto. You may
assign the different type manually by click the caption TPCAM-16 or TPCAM-32. Only Annex AF
and BG can using TCPAM-32.

For 2-wire model (n*64kbps)
You can setup the SHDSL.bis data rate in the multiple of 64kbps.
The default data rate is 5696Kbps (n=89).
For using Annex AF or BG
TCPAM32 ; data rate is 768Kbps ~ 5696Kbps (Nx64kbps, N=12~89)
TCPAM16 ; data rate is 192Kbps ~ 3840Kbps (Nx64kbps, N=3~60)
For uning Annex A or B
TCPAM16 ; 192Kbps ~ 2304Kbps (Nx64kbps, N=3~36)
For 4-wire model (n*128kbps)
You can setup the SHDSL.bis data rate in the multiple of 128kbps.
The default data rate is 11392Kbps (n=89).
For using Annex AF or BG
TCPAM32 ; data rate is 1536Kbps ~ 11392Kbps (Nx128kbps, N=12~ 89)
