  Mediant 800 MSBG 
 
Parameter  Description 
[RAILowThreshold] 
Low threshold percentage of total calls that are active (busy endpoints).
When the percentage of the device's busy endpoints falls below this low 
threshold, the device sends an SNMP acBoardCallResourcesAlarm 
alarm trap with a 'cleared' alarm status. 
The range is 0 to 100%. The default value is 90%. 
[RAILoopTime] 
Time interval (in seconds) that the device periodically checks call 
resource availability. 
The valid range is 1 to 200. The default is 10. 
 
 
12.3.4  Serial Parameters 
The RS-232 serial parameters are described in the table below. (Serial interface is mainly 
used for debugging.) 
Table  12-15: Serial Parameters 
Parameter  Description 
[DisableRS232] 
Enables or disables the device's RS-232 port. 
  [0] = RS-232 serial port is enabled. 
  [1] = RS-232 serial port is disabled (default). 
The RS-232 serial port can be used to change the networking 
parameters and view error/notification messages. For information on 
establishing a serial communications link with the device, refer to the 
Installation Manual. 
Note: For this parameter to take effect, a device reset is required. 
EMS: Baud Rate 
[SerialBaudRate] 
Determines the value of the RS-232 baud rate. 
The valid values include the following: 1200, 2400, 9600, 14400, 19200, 
38400, 57600, or 115200 (default). 
Note: For this parameter to take effect, a device reset is required. 
EMS: Data 
[SerialData] 
Determines the value of the RS-232 data bit. 
  [7] = 7-bit. 
  [8] = 8-bit (default). 
Note: For this parameter to take effect, a device reset is required. 
EMS: Parity 
[SerialParity] 
Determines the value of the RS-232 polarity. 
  [0] = None (default). 
  [1] = Odd. 
  [2] = Even. 
Note: For this parameter to take effect, a device reset is required. 
EMS: Stop 
[SerialStop] 
Determines the value of the RS-232 stop bit. 
  [1] = 1-bit (default). 
  [2] = 2-bit. 
Note: For this parameter to take effect, a device reset is required.
