From HEXONET Wiki
To manage a .TEL domain, a so-called CTH User is needed which is used to login to the .TEL Admin Interface. In some cases this CTH user must be created manually (e.g. after a .TEL domain transfer, ). It can be created using this command:
command = TELNIC_CTH_CreateUser X-TEL-CTH-LOGIN = <TEXT> EMAIL = <EMAIL> (optional) X-TEL-CTH-PASSWORD = <TEXT>
The response will only be visible if no password is given with the command. In this case, a random password is generated.
The CTH User login and password are automatically sent out to the specified email address after the command is executed.
Further details regarding .TEL and the use of the TELNIC specific commands can be found at the .TEL wiki page.
