Hello Chandra,

basically, you need to configure the serial interface (where you connect your RAD modem to) of your 3102 router as asynchronous, the configuration would look something like this:

username REMOTE password cisco

!

chat-script dial "" AT OK "\patdt\T" TIMEOUT 60 CONNECT \C

!

interface Serial0

physical-layer async

no ip address

no ip directed-broadcast (default)

encapsulation ppp

dialer in-band

dialer pool-member 1

async mode dedicated

async defualt-routing

ppp authentication chap

!

interface Dialer1

ip address negotiated

no ip directed-broadcast

encapsulation ppp

dialer remote-name REMOTE

dialer idle-timeout 500

dialer string 123456 modem-script dial

dialer pool 1

dialer-group 1

no cdp enable

ppp authentication chap

!

no ip http server (default)

ip classless (default)

!

ip route 0.0.0.0 0.0.0.0 dialer 1

dialer-list 1 protocol ip permit

!

line con 0

exec-timeout 10 0 (default)

password cisco

login

transport input none (default)

stopbits 1 (default)

line 1

modem InOut

modem autoconfigure discovery

transport input all

speed 115200

flowcontrol hardware

line vty 0 4

password secret

login

!

end

Under your line 1 configuration, if you have a modemcap available for your modem, you could also try:

modem autoconfigure type

followed by the modemcap entry for your RAD modem...

HTH,
