  Mediant 1000B Gateway & E-SBC 
Parameter  Description 
[AUPDDigestPassword]  Defines the password for digest (MD5 cryptographic hashing) access 
authentication with the HTTP server used for the Automatic Update 
feature. 
The valid value is a string of up to 50 characters. By default, no value 
is defined. 
crc-check regular  
[AUPDCheckIfIniChanged] 
Enables the device to perform cyclic redundancy checks (CRC) on 
downloaded configuration files (ini) during the Automatic Update 
process. The CRC checks whether the content (raw data) of the 
downloaded file is different to the content of the previously 
downloaded file from the previous Automatic Update process. The 
device compares the CRC check value (code) result with the check 
value of the previously downloaded file. If the check values are 
identical, it indicates that the file has no new configuration settings, 
and the device discards the file. If the check values are different, the 
device installs the downloaded file and applies the new configuration 
settings. 
  [0] = (Default) Disable - the device does not perform CRC and 
installs the downloaded file regardless. 
  [1] = Enable CRC for the entire file, including line order (i.e., same 
text must be on the same lines). If there are differences between 
the files, the device installs the downloaded file. If there are no 
differences, the device discards the newly downloaded file.  
  [2] = Enable CRC for individual lines only. Same as option [1], 
except that the CRC ignores the order of lines (i.e., same text can 
be on different lines).  
tftp-block-size 
[AUPDTftpBlockSize] 
Defines the size of the TFTP data blocks (packets) when downloading 
a file from a TFTP server for the Automatic Update mechanism. This 
is in accordance to RFC 2348. TFTP block size is the physical packet 
size (in bytes) that a network can transmit. When configured to a 
value higher than the default (512 bytes), but lower than the client 
network’s Maximum Transmission Unit (MTU), the file download 
speed can be significantly increased. 
The valid value is 512 to 8192. The default is 512. 
Note: 
  A higher value does not necessarily mean better performance. 
  The block size should be small enough to avoid IP fragmentation 
in the client network (i.e., below MTU). 
  This feature is applicable only to TFTP servers that support this 
option. 
[ResetNow]  Invokes an immediate device reset. This option can be used to 
activate offline (i.e., not on-the-fly) parameters that are loaded using 
the parameter IniFileUrl. 
  [0] = (Default) The immediate restart mechanism is disabled. 
  [1] = The device immediately resets after an ini file with the 
parameter set to 1 is loaded. 
Note: If you use the parameter in an ini file for periodic automatic 
provisioning with non-
HTTP (e.g., TFTP) and without CRC, the device 
resets upon every file download.
