Adding a Modem to the WMTS – p. 58
Figure 5-21: Selecting and Setting Upstream Channel Parameters
NOTE: For Data Service Type, “Best effort channel” or
“CIR channel” are typically used for a data-only modem.
An “E1 channel” must be used when the modem supports
E1/T1 connections and data. These settings correspond
to the desired SLA (Service Level Agreement.)
The “Tx backoff” settings control the scheduling algorithms used in the upstream
channel. The default values should be used unless your system engineer has indicated
otherwise.
Ensure that the “Optimize channel parameters” box is checked. This causes the WMTS
to maximize the efficiency of the channel usage for the different types of modems
assigned to it.
Set this to ‘up” to operate this
channel or “down” to turn it off
