i try to configure scdam on C3 cardan but i don't have a good result. Below the message i obtain when trying to configure docsis 2.0:
C3#
C3#conf ter
C3(config)#int c1/0
C3(config-if)#cab

C3(config-if)#cable upstream 0.0 channel-ty

SCDMA not currently licensed - contact Arris support
SET for US channel type failed

Please, somebody has any idea.

Hi!
You must have a license for SCDMA feature. You can see the license on the CMTS:
C3>
C3>ena
C3#licence key ââ¬Â¦ feature ââ¬Â¦
C3# sh lic
I dont know the license is how much. If not very important the SCDMA, I prefer the ATDMA.

It is correct that you require a SCDMA license key - until the 4.4 software family. Starting in 4.4, the license is no longer required and you can simply enable a SCDMA logical channel IF YOUR HARDWARE SUPPORTS IT.
To use SCDMA, you must have a C3 CMTS with Broadcom 3140 Upstream receivers. If you have 3138's, your hardware does not support that modulation technique.
use the command "show hardware" to find your receivers, then look for what is in your Upstream Slots:
Upstream Slot 0 BCM3140
That is an example of a chipset which supports SCDMA
Hope this helps !

Hi!
Here is the output with SCDMA license CMTS:
----------------------------------------------------------------------
C3 - hostid 5181 - Licensed Features
* SCDMA ARSVSxxxxx
----------------------------------------------------------------------
We are using both SCDMA and ATDMA. I to observe if the TDMA Upstream SNR is about 25dB when the SCDMA USNR is 35.

Lewis,
To enable your SCDMA licence key, use this format:
C3#license key feature ARSVS01193
If you run into trouble, contact us at ARRIS Tech Support.
Cheers!
C3#license key scdma ARSVSxxxxx
% Unknown command
C3#
