Hi

access is controlled by the  line "  access-class 23 in" towards the end of the config

line vty 0 4
 access-class 23 in
 exec-timeout 120 0
 privilege level 15
 password 111111
 login
 length 0

you need to add your local network  to access list 23 to allow access

 access-list 23 permit 192.168.0.0 0.0.0.255

A better solution would be to use SSH, as telnet does not encrypt your password.  If you want to go this route you will need an IOS image that supports encryption (indicated by "K9" in the file name).  To enable, do the following:

Crypto Key Generate RSA
Line Vty 0 4
  transport input SSH

The same access-list 23 can be used for this purpose, but you can allow it to a broader range of IP's, since the traffic is encrypted.
