Sendat - H3C MSR810 Command Reference Manual

low lowthreshold: Specifies the lower RSSI threshold value in the range of 0 t o 150, which
represents a lower RSSI threshold in the range of –150 dBm to 0 dBm. The value of lowthreshold
cannot be s maller than the value of mediumthreshold because the system automatically adds a
negative sign to the RSSI thresholds.
medium mediumthreshold: Specifies the upper RSSI threshold value in the range of 0 to 150, which
represents an upper RSSI threshold in the range of –150 dBm to 0 dBm.
Usage guidelines
The device performs the following operations based on the actual RSSI of the 3G/4G modem:
• Sends a trap that indicates high RSSI when the RSSI exceeds the upper threshold.
• Sends a trap that indicates normal RSSI when the RSSI is between the lower threshold and
upper threshold (included).
• Sends a trap that indicates low RSSI when the RSSI drops to or below the lower threshold.
• Sends a trap that indicates low RSSI every 10 minutes when the RSSI remains equal to or
smaller than the lower threshold.
To view the RSSI change information for a 3G/4G modem, use the display cellular command.
Examples
# Set the lower threshold for a 3G/4G modem in GSM mode to –110 dBm.

sendat

Use sendat to issue a configuration directive to a 3G/4G modem.
Syntax

Predefined user roles

Parameters
at-string: Specifies a configuration directive string, a string of 1 to 300 characters. This argument can
be an AT directive (containing +++, A/, or be any string beginning with AT) or a CNS directive. For
more information about AT directives, see the sendat command in Layer 2—WAN Access
Command References.
Table 55 CNS directive description
Directive
CNSn
Usage guidelines
The sendat command does not verify the configuration directive. Each time it issues one
configuration directive to the 3G/4G modem, lowercase characters are automatically converted to
uppercase characters.
Table 55 describes the CNS directive samples.
Description
Controls the CNS heartbeat debugging switch.
• n = 00000500000000000000—Enables CNS heartbeat debugging.
• n = 00000800000000000000—Disables CNS heartbeat debugging.
