What are the admin credentials for DBC ONU?

[Shivpal]

I got new BSNL fibernet connection and they gave me this blue DBC technologies ONU router device, which is the same as Netlink or Syrotech but different branding.

The ip for configuration is mentioned as 192.168.1.1
The user credentials are name: user ; password : user
But admin credentials I'm unable to find
I've tried the usual passwords : null, admin, password, stdONU101(default for Netlink) but none are working.

If anyone knows the default password admin password please help.
