Need help to configure a terminal server with reverse telnet

Hi all,
I would like to know if someone has an example of router config for a terminal server.
In fact I need a configuration for a router with multiple, low speed, asynchronous ports that are connected to other serial devices, for example,
modems or console ports on routers or switches.
With this router I would like to use a reverse telnet to connect with my devices using the serial connection.
I find many examples on the Cisco web site but none with my router hardware configuration.
My router is a 3620 router with a 8 port async (NM-8A/S) network module and I would like to use the 8 serial interfaces, each of them connecting a serial device.

Thank you by advance.

Here is the show run and show ver :
