Please tell me how to solve the problem:
It is necessary to connect IP-LANs
central and regional offices over x25 network.
In region, router connected to x25 network trought x25 protocol.
In Center, in additional, need connect to Internet.
router 2650 connected to ISP trougth Frame Relay with two DLCI:
dlci-110 for x25, dlci-316 for PPP to Internet.
Used protocol fully equivalent given here example:
http://www.cisco.com/warp/public/133/x25_over_frame_wo_tcp.html
In this cheme Router-1 equivalent regional router 1750.
Router-3 equivalent central router 2650.
Router-2 and Router-4 is ignored.
In given example, command "x25 map ip ..." make
interconnecting networks routers 1 and 4
But need interconnect networks routers 1 and 3
The problem is that, in Router-3 Annex G is used
and there is no opportunity to use command
(Config-if)# x25 map ip 10.0.0.2 1234
How interconnect IP-LANs routers 1 and 3 ?
my current config:
2 additional Serial with crossover cable.

I wonder if this is an IOS feature yours doesn't support. You should check it on feature navigator at www.cisco.com/go/fn

we do not support IP encapsulation in the x25 profiles for annexg - it is a method for remote switching of X25 packets. Please see link below:

It's clear that is IOS do not support IP encapsulation in the x25 profiles for annexg.
That's why we use following configuration:
At this moment we installed an additional two-port
unit WIC-2T into 2650, bind its ports by pair of DTE-DCE cables to
each other and transmit X.25 traffic from Frame-Relay to one of those
additional ports, get the traffic from another additional port and do
"x25 map ip..." on it.
It's amazing that's Cisco IOS can't realize more correct solution?
would the command "translate" help me in this problem ?
