There are a fair few Cerberus customers on here, would be interested to hear from them if they have any discrepancy between their ONT SN and whats on the Cerberus account.
It's not a discrepancy so much, as far as I can see it's a different number altogether, although they are variously both termed "serial numbers" they do not "match" on my Cerberus account.
The first "serial number" on the account is effectively the user ID associated with the account, and as such makes up the first part of the PPPoE login detail. It is an 11 digit numeric (only no alpha characters) with six leading zeros. The last five numbers are unique.
The physical serial number of the ONT is a 16 mixed alpha and numeric ID in the format 48575443NaaNNNNa, where 'a' is an alphabetic char and 'N' is numeric. At least that's what it is on a Huawei. The two "serial numbers" bear no other resemblance to each other than sharing the same (possibly confusing) nomenclature....
