Synoptics Display for XMTS Configuration – p. 133
5. Click on the “QoS” tab to display the Quality of Service screen and check
the appropriate QoS box. “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).
6. 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.
7. Ensure that the “Optimize channel parameters” box is checked. This
causes the XMTS to maximize the efficiency of the channel usage for the
different types of modems assigned to it. Check the “Save WMTS
configuration” box and click on the “OK” button to permanently
reconfigure the XMTS with these settings.
Note: This box is used for both E1 and T1 connections.
