Open a terminal with applescript

Question

I am using this script to open a terminal session and telnet:
tell application "Terminal"
  activate
          tell application "System Events" to keystroke "n" using {command down}
          do script "telnet ipaddress" in front window
  delay 5
  do script "username" in front window
  delay 5
          do script "password" in front window
  delay 5
  do script "command to close session" in front window
end tell
When I run this it opens two terminal windows  is there a way to only open the one?  I have read other threads but they were all archived and didn't address two windows opening.

try
          set pathToMyFolderOnDesktop to ("Macintosh HD:Users:jodyconnor:Desktop:") & "Dsource:" as alias
          set rnd to (random number from 1 to 6)
          set rndFileName to (rnd as text) & ".scpt"
          set FullPath to pathToMyFolderOnDesktop & rndFileName as text
          set myScript to load script (FullPath as alias)
  run script myScript
on error the error_message number the error_number
          display dialog "Error: " & the error_number & ". " & the error_message buttons {"OK"} default button 1
          return
end try
