Cisco Router - 2900 and 2600 - Console lines Issue

[Yasmeen]

Hi Team 

        In our Office Lab we are using 2900 routers and 2600 routers as terminal server and each terminal server has console lines - TTY (24 lines). 

        recent days all lines consoles opened after router credentials. 

        previously the connected consoles open as it is without terminal server credentials

        when ever i open any tty line after clear line - first it asked for terminal server credentials after that TTY line connected device console opened 

         anybody please help me to configure only tty lines open without router credentials. 

Thanks,

Yasmeen Shaul Hameed,
