Chapter 5      Configuring Backup Data Lines and Remote Management
  Configuring Data Line Backup and Remote Management Through the ISDN S/T Port
To configure your router ISDN interface for use as a backup interface, perform these steps, beginning in 
global configuration mode:
CommandPurpose
Step 1isdn switch-type switch-type
Example:
Router(config)# isdn switch-type basic-net3
Router(config)#
Specifies the ISDN switch type.
The example specifies a switch type used in 
Australia, Europe, and the United Kingdom. For 
details on other supported switch types, see the 
Cisco IOS Dial Technologies Command 
Reference.
Step 2interface type number
Example:
Router(config)# interface bri 0
Router(config-if)#
Enters configuration mode for the ISDN Basic 
Rate Interface (BRI). 
Step 3encapsulation encapsulation-type
Example:
Router(config-if)#encapsulation ppp
Router(config-if)#
Sets the BRI0 interface encapsulation type.
Step 4dialer pool-member number
Example:
Router(config-if)# dialer pool-member 1
Router(config-if)#
Specifies the dialer pool membership.
Step 5isdn switch-type switch-type
Example:
Router(config-if)# isdn switch-type 
basic-net3
Router(config-if)#
Specifies the ISDN switch type.
Step 6exit
Example:
Router(config-if)# exitRouter(config)#
Exits configuration interface mode and enters 
global configuration mode.
Step 7interface dialer dialer-rotary-group-number
Example:
Router(config)# interface dialer 0
Router(config-if)#
Creates a dialer interface (numbered 0 to 255) and 
enters interface configuration mode.

  Configuring Data Line Backup and Remote Management Through the ISDN S/T Port
Step 8ip address negotiated
Example:
Router(config-if)# ip address negotiatedRouter(config-if)#
Specifies that the IP address for the interface is 
obtained through PPP/IPCP (IP Control Protocol) 
address negotiation. The IP address is obtained 
from the peer.
Step 9encapsulation encapsulation-type
Example:
Router(config-if)# encapsulation ppp
Router(config-if)#
Sets the encapsulation type to PPP for the 
interface.
Step 10dialer pool number
Example:
Router(config-if)# dialer pool 1
Router(config-if)#
Specifies the dialer pool to be used. 
In the example, the dialer pool 1 setting associates 
the dialer 0 interface with the BRI0 interface 
because the BRI0 dialer pool-member value is 1.
Step 11dialer string dial-string#[:isdn-subaddress]
Example:
Router(config-if)# dialer string 384040
Router(config-if)#
Specifies the telephone number to be dialed.
Step 12dialer-group group-number
Example:
Router(config-if)# dialer group 1
Router(config-if)#
Assigns the dialer interface to a dialer group 
(1–10).
Step 13exit
Example:
Router(config-if)# exitRouter(config)#
Exits dialer 0 interface configuration mode, and 
enters global configuration mode.
Step 14dialer-list dialer-group protocol protocol-name 
{permit | deny | list access-list-number | 
access-group} 
Example:
Router(config)# dialer-list 1 protocol ip 
permit
Router(config)#
Creates a dialer list for packets of interest to be 
forwarded through the specified interface dialer 
group. 
In the example, dialer-list 1 corresponds to 
dialer-group 1.
For details about this command and additional 
parameters that can be set, see the 
Cisco IOS Dial 
Technologies Command Reference.

Configuring Aggregator and ISDN Peer Router
The aggregator is typically a concentrator router where your Cisco router ATM PVC terminates. In the 
following configuration example, the aggregator is configured as a PPPoE server. 
The ISDN peer router is any router that has an ISDN interface and can communicate through a public 
ISDN network to reach your Cisco router ISDN interface. The ISDN peer router provides Internet access 
for your Cisco router during the ATM network downtime.

Configuring the Cellular Wireless Interface
To configure the 3G wireless interface, follow these guidelines and procedures:
 Restrictions for Configuring Cellular Wireless Interface
 Configuring Data Account Provisioning
 Configuring a Cellular Interface
 Configuring a GSM Modem Data Profile (GSM only)
 CDMA Modem Activation and Provisioning (CDMA only)
 Data Call Setup
Restrictions for Configuring Cellular Wireless Interface
The following restrictions apply to configuring the Cisco 3G wireless interface:
 A data connection can be originated only by the 3G wireless interface. Remote dial-in is not 
supported.
 Because of the shared nature of wireless communications, the experienced throughput varies 
depending on the number of active users or the amount of congestion in a given network. 
 Cellular networks have higher latency than wired networks. Latency rates depend on the technology 
and carrier. Latency may be higher when there is network congestion.
 VoIP is not currently supported.
 Any restrictions that are part of the terms of service from your carrier also apply to the Cisco 3G 
wireless interface.
Configuring Data Account Provisioning
NoteTo provision your modem, you must have an active wireless account with a service provider and a SIM 
card installed in your 3G wireless card.
To provision your data account, follow these procedures:
 Verifying Signal Strength and Service Availability, page 5-15
 Configuring a GSM Modem Data Profile, page 5-16
 CDMA Modem Activation and Provisioning, page 5-17
Verifying Signal Strength and Service Availability
To verify the signal strength and service availability on your modem, use the following commands in 
privileged EXEC mode.

Chapter 5      Configuring Backup Data Lines and Remote Management
  Configuring the Cellular Wireless Interface
The following table lists the activation and provisioning processes supported by different wireless 
carriers. 
Manual Activation
NoteYou must have valid mobile directory numner (MDN), mobile subsidy lock (MSL), and mobile station 
identifier (MSID) information from your carrier before you start this procedure.
To configure a modem profile manually, use the following command, beginning in EXEC mode: 
cellular 0 cdma activate manual mdn msid sid nid msl
Besides being activated, the modem data profile is provisioned through the Internet Over the Air (IOTA) 
process. The IOTA process is initiated automatically when you use the cellular cdma activate manual 
command. 
Here is a sample output from this command: 
router# cellular 0 cdma activate manual 1234567890 1234567890 1234 12 12345 NAM 0 will be configured and will become Active

*Feb  6 23:29:41.679: IOTA Status Message Received. Event: IOTA End, Result: SUCCESS
The IOTA start and end must have “success” as the resulting output. If you receive an error message, you 
can run IOTA independently by using the cellular cdma activate iota command. 
Your carrier may require periodic refresh of the data profile. Use the following command to refresh the 
data profile:
