Information Needed for Configuration
You need to gather some or all of the following information, depending on your planned network scenario, before configuring your network:
•If you are setting up an Internet connection, gather the following information:
– PPP client name that is assigned as your login name
–PPP authentication type: Challenge Handshake Authentication Protocol (CHAP) or Password Authentication Protocol (PAP)
–PPP password to access your Internet service provider (ISP) account
–DNS server IP address and default gateways
•If you are setting up a connection to a corporate network, you and the network administrator must generate and share the following information for the WAN interfaces of the routers:
–PPP authentication type: CHAP or PAP
–PPP client name to access the router
–PPP password to access the router
•If you are setting up IP routing:
–Generate the addressing scheme for your IP network.
–Determine the IP routing parameter information, including IP address and ATM permanent virtual circuits (PVCs). These PVC parameters are typically virtual path identifier (VPI), virtual circuit identifier (VCI), and traffic-shaping parameters.
–Determine the number of PVCs that your service provider has given you, along with their VPIs and VCIs.
–For each PVC determine the type of AAL5 encapsulation supported. It can be one of the following:
AAL5SNAP—This can be either routed RFC 1483 or bridged RFC 1483. For routed RFC 1483, the service provider must provide you with a static IP address. For bridged RFC 1483, you may use DHCP to obtain your IP address, or you may obtain a static IP address from your service provider.
AAL5MUX PPP—With this type of encapsulation, you need to determine the PPP-related configuration items.
•If you plan to connect over an ADSL or G.SHDSL line:
–Order the appropriate line from your public telephone service provider.
For ADSL lines—Ensure that the ADSL signaling type is DMT (also known as ANSI T1.413) or DMT Issue 2.
For G.SHDSL lines—Verify that the G.SHDSL line conforms to the ITU G.991.2 standard and supports Annex A (North America) or Annex B (Europe).
Once you have collected the appropriate information, you can perform a full configuration on your router, beginning with the tasks in the "Configuring Basic Parameters" section.
•If you plan to connect voice equipment:
–Seethe Cisco IOS Voice Port Configuration Guide
•If you plan to install 3G backup:
–See Chapter 5, "Configuring Backup Data Lines and Remote Management"
•To obtain or change software licenses:
–See Software Activation on Cisco Integrated Routers

Configuring the Cellular Wireless WAN Interface
The Cisco 881G and 888G ISRs provide a Third Generation (3G) wireless interface for use over Global System for Mobile Communications (GSM) and code division multiple access (CDMA) networks. Its primary application is WAN connectivity as a backup data link for critical data applications. However, the 3G wireless interface can also function as the primary WAN connection. The interface is a 34-mm PCMCIA slot.
To configure the 3G cellular wireless interface, follow these guidelines and procedures:
•Prerequisites for Configuring the 3G Wireless Interface
•Restrictions for Configuring the Cellular Wireless Interface
•Data Account Provisioning
•Configuring a Cellular Interface
•Configuring DDR
•Examples for Configuring Cellular Wireless Interfaces
Prerequisites for Configuring the 3G Wireless Interface
The following are prerequisites to configuring the 3G wireless interface:
•You must have wireless service from a carrier, and you must have network coverage where your router will be physically placed. For a complete list of supported carriers, see the data sheet at the following URL:
http://www.cisco.com/go/3g
•You must subscribe to a service plan with a wireless service provider and obtain a SIM card (GSM modem only) from the service provider.
•You must check your LEDs for signal strength as described in Table 3-2.
•You should be familiar with the Cisco IOS software, beginning with Cisco IOS Release 12.4(15)XZ or later for Cisco 3G Wireless support. (See the Cisco IOS documentation.)
•To configure your GSM data profile, you will need the following information from your service provider:
–Username
–Password
–Access point name (APN)
•To configure your CDMA data profile for manual activation, you need the following information from your service provider:
–Master Subsidy Lock (MSL) number
–Mobile Directory number (MDN)
–Mobile Station Identifier (MSID)

Restrictions for Configuring the 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.
Data Account Provisioning
Note To provision your modem, you must have an active wireless account with a service provider. A SIM card must be installed in a GSM 3G wireless card.
To provision your data account, follow these procedures:
