Configuring the Dialing Access Server
Defining Modem Parameters on the Dialing Access Server
Perform the following steps to configure modem support for an access server initiating DDR calls
(Woodstock):
Step 1 Configure the line speed. In the following example, line speed is set to 115200 bps. If you
are configuring dialout on an AUX port, the maximum speed is 38400 bps.
Woodstock(config)# line tty 1
Woodstock(config-line)# speed 115200
Step 2 Configure flow control on the line making the outgoing DDR call.
Woodstock(config-line)# flowcontrol hardware
Step 3 Because the access server is making outgoing calls on line 1 only, configure the modem
to make outgoing calls on that line.
Woodstock(config-line)# modem inout
Step 4 Define a chat script to send commands to the modem (note that chat scripts are case
sensitive).
Woodstock(config)# chat-script dialnum "" "atdt\T" TIMEOUT 60 CONNECT \c
This script, named dialnum, sends the atdt string to the modem. The \T in the script
specifies that the phone number that appears in the dialer map statement be sent (see
Step 8 in the section “Configuring the Asynchronous Interface Dialing the DDR Call”).
Step 5 Create a chat script to initialize the modem making the DDR call. In this case, the name
of the chat script is rstusr. When this script is executed, the modem string
at&fs0=1e0&r2&d2&c1&b1&h1&m0&k0 is sent.
Woodstock(config)# chat-script rstusr "" "at&fs0=1e0&r2&d2&c1&b1&h1&m0&k0" "OK"
Other modems require similar settings, but different syntax. In this example, this script is
executed by the script reset rstusr command, as shown in the following step.
Step 6 Assign the chat script rstusr to the asynchronous line.
Woodstock(config)# line tty 1
Woodstock(config-line)# script reset rstusr
The reset string causes the chat script rstusr to be sent to the modem when the line is
reset.
Step 7 Enable pulsing DTR signal intervals on the asynchronous interface to ensure that the
modem properly disconnects by using the pulse-time command. This command is
needed on the dialing access server only.
Woodstock(config-line)# interface async 1
Woodstock(config-if)# pulse-time 3
Configuring Routing and a Routing Protocol on the Dialing Access Server
Perform the following steps to configure RIP routing on the access server initiating DDR calls
(Woodstock):
Step 1 Configure RIP routing globally on the access server:
Woodstock(config)# router rip
Woodstock(config-router)#
