CISCO 2921 Router Basic Configuration - line 2 & line 68

I'm configuring a router (and I use that term loosely as I'm really a UNIX Administrator that has a couple of CISCO classes about 3 years ago - which now makes me the resident CISCO expert) and the router has these lines.

line 2
  no activation-character
  no exec
  transport preferred none
  transport output pad telnet rlogin lapb-ta mop udptn v120 ssh
  stopbits 1
line 68
  no activation-character
  no exec
  transport preferred none
  transport input all
  transport output pad telnet rlogin lapb-ta mop udptn v120 ssh
  stopbits 1

I don't know what these are.   I have one T3 Serial WAN card, and 3 Gigabit Ethernet interfaces -- nothing is working right now except the ping to the next hop -- I'm still applying DISA STIG settings to the system.   Since I don't know what these "lines" , I need to know and if they are not needed, I should really remove them which apparently I can't since typing no line 2 or no line 68, doesn't yield anything.

Thanks!

This line cannot be removed. Line 2 is reserved for 2nd core console for all of the ISR G2 platforms. The line is used to provide a console to the embedded service engine on these platforms. There is nothing you can do about it nor will it affect the operation of the router.
