80 LEDR Series I/O Guide MDS 05-3627A01, Rev. D
This command displays the received signal strength. The measurement
is in dBm. Therefore, an RSSI of –80 dBm is stronger than a –100 dBm
signal. There may be a time delay between moving the antenna and
updating of the RSSI display. Be sure to allow adequate time between
antenna movements and observations.
rssical RSSI Calibration
Usage:
rssical <freq region#> <cal-point#>
This command starts the RSSI Calibration Sequence. See rfocal com-
mand
on Page 76 for conditions.
CAUTION:This command should never be used unless calibrated test
equipment has shown the radio to have inaccurate RSSI
calibration. Contact the Technical Services Group at
MDS for further instructions before using this
command.
Example entry:
rssical
Example Response:
Region 0
Index 0, RSSI = –110 dbm, Gain = –104
Index 1, RSSI = –90 dbm, Gain = –40
Index 2, RSSI = –75 dbm, Gain = +1
Index 3, RSSI = –60 dbm, Gain = +28
Index 4, RSSI = –45 dbm, Gain = +61
Index 5, RSSI = –30 dbm, Gain = +97
rxlock Receiver locked onto Remote radio
Usage:
rxlock
This command displays the current modem synchronization status.
Example Response:
: rxlock: Modem is locked
sabytes SA Bytes in E1 Multi-framing
Usage:
sabytes [linelist] [bytes <bytelist>]
This command is used to set or display SA bytes in E1 multiframing.
The
[linelist] variable represents a list of line interfaces. It can consist of
a single line number or line name, a comma-separated list of line num-
bers or line names, a range of line numbers (i.e., 1–4), or if linelist is not
given all lines. See Table 19 on Page 59 for a list of line numbers.
The
bytelist variable consists 5 hex bytes (i.e., 3c) representing SA[4-8].
To keep a bytes present value when modifying higher bytes (i.e., modi-
fying SA[7] only) use a * character in the respective byte position.
Example:
sabytes 1 bytes *,*,*,3c changes only SA[7] for line 1 to 3c.
