Tasman 4100 CRC and KeepAlive parameters for DS3 connection

Hi,

We got an old (but new) Tasman 4100 router to handle the DS-3 connection. We managed to set it up with Verizion for the WAN connection. With scrambling, the line was failing; without it it is much better, but it looks like the CRC and KeepAlive values are incompatible. However I am failing to find any way to configure these values or even to look at the defaults!

How do I find, and even better - set the CRC and KeepAlive values for T3/DS3 link in Tasman 4100 router?

I haven’t touched one of those in awhile but there isn’t much in there to configure.
Pretty much just alarms, clocking and cable length.

Here are a couple of warning type notes from the manual if you haven’t seen them already:

DS3 scrambling is not supported.

The Clear Channel DS3 interface module does not currently support the use of the M13
framing format. Only the default framing format of C-BIT can be used on Clear Channel DS3
interface modules.

Jumbo frames must be enabled in the system setting to allow DS3 module to connect with
other vendors.

Thanks for being someone finally attending to this question.

Unfortunately, this doesn't answer the question about the default settings of CRC and KeepAlive. :(

We got rid of the Tasman, bought a used Cisco 7204 for $299.
For others: do not use Tasman in modern circuits.
