+ When the device generates a seed it combines the number of seconds since 1970-01-01 00:00:00
+ with the router MAC address. Both are encoded in a single 6-byte hexadecimal
+
+ Each value is truncated to its 3 least significant bytes so, for example:
+
+ $ date +%F.%T; echo "obase=16;$(date +%s)" | bc
+ 2016-03-26.23:06:32
+ 56F715F8
+ # MAC Address: EC:43:F6:46:C0:80
+
+ becomes F715F8 concatenated with 46C080
+
+ CFE> ATSE DSL-2492GNAU-B1BC
+ F715F846C080 <<<< last 3 bytes of MAC address
+ ^^^^^^
+ seconds since 1970-01-01 00:00:00 (2016-03-26 23:06:32)
+
+ *NOTE: the default seed after power-up is 000000 so no time value needs to be specifed
+ if "ATSE <model-id-string>" has not been executed on the device.
+
+ Access to the device's console via a serial UART port, or a network telnet/ssh session,
+ is required to enter the password.
