Receive Signal Quality (rsq)

Use the rsq command to test the quality of the signal being received by a DATAPHONE II Analog

Private Line (APL) modem or Direct Distance Dial (DDD) modem. Received signal quality is an

overall gauge of the data channel’s performance and is given as a figure of merit in the range of 0

(satisfactory) to 9 (poor).

For most commands, NMS enables you to specify the destination for the command’s results and

schedule its execution. If the last page of the input form cannot accommodate the Destination for

results and Schedule execution fields, an additional page is provided. For a complete description

of these fields, refer to Chapter 1, Introduction.

Receive Signal Quality Input Form

This input form contains the following field:

Device(s) (Required field)

Enter the device(s) for which the receive signal quality will be measured. One or more

devices may be entered. Standard addressing format applies to the input. For information

on device addressing, refer to Appendix D of the COMSPHERE 6800 Series Network

Management System User’s/System Administrator’s Guide.

Receive Signal Quality Results Form

This results form displays device information for each device specified, the figure of merit

measure (0–9) associated with the measured received signal level, and the estimated block error.

Up to one block error per thousand blocks transmitted is considered good performance. Results

falling between one block error per 100 blocks and one block error per 1000 blocks are considered

satisfactory. Poor performance is indicated if more than one block error per 100 blocks occurs.

If line signal quality is satisfactory or poor, you should investigate further using the Signal Profile

(sp) command.
