Circuit Loss Inbound (cli)
(Disruptive)
Use the cli command to measure the inbound circuit loss to a specified COMSPHERE APL
modem or DATAPHONE II APL modem from an associated tributary. Tributary DATAPHONE II
modems transmit a specified frequency over the primary data channel for approximately
2.5 seconds at a signal level between –2 dBm and 0 dBm. COMSPHERE tributary modems
transmit their normal frequency spectrum at the currently optioned (typically 0 dBm) signal level.
The control device measures the level of the received signal, which should nominally be –16 dBm.
The overall accuracy of this test is
±
2 dBm.
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.

Circuit Loss Inbound Input Form
The Circuit Loss Inbound input form enables you to specify the control and tributary device(s) for
which this command will be executed, and to enter the tone frequency to be transmitted by the
tributary.
This input form contains the following fields:
Control device(s) (Required field)
Enter the control device(s) for which the tone will be measured. One or more devices may
be specified. 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.
Tributary device(s) (Required field)
Enter the tributary device(s) that will transmit the tone. One or more devices may be
specified. 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.
Tone frequency (Required field)
Enter the tone frequency to be transmitted. Valid entries are 1004, 1804, or 2804 Hz.
A pop-up menu is available listing valid selections.
