TCPAM16 ; 192Kbps ~ 2304Kbps (Nx64kbps, N=3~36)
For 4-wire model (n*128kbps)
You can set up 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 3841536Kbps ~ 11392Kbps (Nx128kbps, N=312~ 89)
TCPAM16 ; data rate is 384Kbps ~ 7680Kbps (Nx128kbps, N=3~60)
Annex AF/BG TCPAM-16 192~3840 kpbs
TCPAM-32 192~5696 kpbs
4.1.5 SNR margin:
This is an index for line connection quality. You can see the actual SNR margin in STATUS
SHDSL.bis. The larger the SNR margin is, the better the line connection quality is.
The range of SNR margin is -10 to 21.
If you set SNR margin in the field as 3, the SHDSL.bis connection will drop and reconnect
when the SNR margin is lower than 3. On the other hand, the device will reduce the line rate
and reconnect for better line connection quality.
4.1.6 TC Layer:
There are two TC layer setting on this router: EFM layer and ATM layer. It is based on the
networks connected: ATM-based Access Network or Ethernet-based Access Network.
Rate Mode: For adaptive mode, you have to configure it in rate mode. The router will adapt the
optimal data rate according to the line status.
