Here is a basic one to get you on track:
permit w.x.y.z/24 x.y.z.y/32 tcp dst eq 23
deny 0.0.0.0/0 x.y.z.y/32 tcp dst eq 23
permit 0.0.0.0/0 0.0.0.0/0 ip
Line 1 permit telnet to the PM from the /24 address block
Line 2 deny all other telnet to the /32 ip of the PM
Line 3 allow everything else
Without line 3 all other IP packets would be killed.
