Table 2 explains each of the LEDs with their functionality and the different states. The LEDs provide a visual indication of your available services. Please refer to Chapter 13 in the Cisco Interface Cards Hardware Installation Guide for details on hardware installation.

Table 2 3G Wireless HWIC (CDMA) LED Descriptions 

LED	Description
RSSI	Off: Low RSSI (under -100 dBm).
	Slow Green Blink: Low or medium RSSI (-99 to -90 dBm).
	Fast Green Blink: Medium RSSI (-89 to -70 dBm).
	Solid Green: High RSSI (-69 dBm or higher).
	Solid Yellow: No service or no RSSI detected.
WWAN	Off: HWIC in reset mode or not powered.
	Slow blink: Searching for service.
	Solid Green: Active service; no traffic detected.
	Fast Blink: Active service, and traffic detected proportional to blink rate.
1xRTT	1xRTT is the active service.
EVDO	1xEVDO is the active service.
Note Both 1xRTT and EVDO Off: No service is active. Note If the RSSI LED is solid yellow, it means that no service and no RSSI are detected. Note Active service means the currently available service. Your 3G WAN wireless HWIC automatically selects the best available connection.

The 3G wireless HWIC provides the following software functionality:

•Modem activation—You can activate the modem either by using Cisco IOS commands either manually or by using over-the-air service provisioning (OTASP).

•Modem management—You can access modem software and hardware information, radio and network status, and data profile information using Cisco IOS commands.

•Dial-on-demand routing (DDR)—This allows you to set up a data call when there is data traffic to be sent over the wireless network.

•Fallback connection (DDR backup)—The 3G wireless HWIC allows you to configure the cellular modem to initiate a dialup connection when connection to a primary service is lost.

•Teardown after fallback (part of fallback DDR)—After a primary connection has failed and the cellular connection is in fallback mode, the 3G wireless HWIC tears down the connection when the primary connection is available.

•Automatic teardown—After a configurable timeout value, the 3G wireless HWIC automatically tears down a connection if there has been no activity.

•Portable application—You can move the router into different coverage areas (different base stations within the same service provider network) and the router establishes a connection with the nearest cell infrastructure automatically.

•Autodetect—The 3G wireless HWIC automatically detects and uses the best available service.

•Firmware upgrade—You can upgrade the firmware on the modem by using Cisco IOS commands.

Prerequisites for Configuring the 3G Wireless HWIC

The following are prerequisites to configuring the 3G wireless HWICs:

•You must have service availability from a wireless service provider, and you must have network coverage where your router will be physically located. 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. For manual activation, you will need the following specific information from the provider:

–Master Subsidy Lock (MSL) number

–Mobile Directory number (MDN)

–MSID

–Electronic Serial Number (ESN)

---

Note The ESN number is on the modem itself, as shown in Figure 2. Make sure that your service is registered with the ESN number. You can also obtain the ESN by using the show cellular hardware command.

---

•You must install the required antennas before you configure the 3G wireless HWIC. See the following URLs for instructions on how to install the antennas:

–3G-ANTM1919D—See the Cisco Multiband Swivel Mount Dipole Antenna (3G-ANTM1919D)

–3G-ANTM1916-CM—See the Cisco Multiband Omnidirectional Ceiling Mount Antenna (3G-ANTM1916-CM)

–3G-AE015-R (Antenna Extension)—See the Cisco Single-Port Antenna Stand for Multiband TNC Male-Terminated Portable Antenna (3G-AE015-R)

•You must make sure to check your LEDs for signal reception as described in Table 2.

•You should be familiar with Cisco IOS.

Restrictions for Configuring the 3G Wireless HWIC

The following restrictions apply to the Cisco 3G Wireless HWICs:

•Data connection can be originated only by the 3G wireless HWIC. Remote dial-in is not supported.

•Throughput—Because of the shared nature of wireless communications, the amount of throughput that is experienced varies, depending on the number of active users or congestion in a network.

•Cellular networks have higher latency, compared to wired networks. Latency rates depend on the technology and carrier. Latency can increase because of network congestion.

•VoIP is not supported.

•Any restrictions that are a part of the terms of service from your carrier.

Technology Overview

This section contains the following topics:

•CDMA Network Overview

•Supported Cisco Antennas and Cables

CDMA Network Overview

CDMA is a standard for mobile communication. A typical CDMA network includes terminal equipment, mobile termination, base transceiver station (BTS), base station controller (BSC), packet data serving node (PDSN), and other data network entities. The PDSN is the interface between a BSC and a internet gateway.

Figure 3 shows the relationship of the components of a typical CDMA network, including a PDSN and a branch office with the 3G wireless HWIC.

As the figure shows, the branch office connects to a radio tower and a BTS. The BTS connects to a BSC, which contains a component called the packet control function (PCF). The PCF communicates with the Cisco PDSN for data communication and with the mobile switching center (MSC) for voice.

Configuring the 3G Wireless HWIC

To configure the 3G wireless HWIC, you must do the following procedures:

•Modem Activation and Provisioning

•Data Call Set up

Modem Activation and Provisioning

To activate and provision your modem, follow these procedures:

•Verifying Signal Strength and Service Availability

•Activating the Modem

Verifying Signal Strength and Service Availability

SUMMARY STEPS

To verify the signal strength and service availability on your modem, use the following commands beginning in the EXEC mode.

---

Note For modem activation, you should be attached to a 1xRTT/EVDO service.

---

1. show cellular network

2. show cellular radio

3. show cellular all

DETAILED STEPS

Use the following commands to verify the signal strength and service availability on your modem beginning in the EXEC mode:

	Command or Action	Purpose
Step 1	Router# show cellular <slot/wic/port> network Example: Router# show cellular 0/0/0 network	Displays information about the carrier network, cell site, and available service.
Step 2	Router# show cellular <slot/wic/port> radio Example: Router# show cellular 0/0/0 radio	Shows the radio signal strength. Note The RSSI should be better than -90 dBm for steady and reliable connection and better than -80 dBm for optimal data throughput.
Step 3	Router# show cellular <slot/wic/port> all Example: Router# show cellular 0/0/0 all	Shows consolidated information about the modem, profiles created, radio signal strength, network security, and so forth.

Activating the Modem

The activation procedures may differ depending upon your carrier. Consult your carrier, and follow one of the following procedures:

•Manual Activation

•Activating Using OTASP

The following table lists activation and provisioning process suupported by different wireless carriers.

Activation Process	Carrier
Manual Activation using MDN/MSID/MSL	Sprint
OTASP Activation	Verizon Wireless
IOTA for Data Profile refresh	Sprint

Manual Activation

---

Note You must have valid MDN, MSL, and 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 slot/wic_slot/port cdma activate manual mdn msid sid nid msl

For more infomation about the parameters, see the "cellular cdma activate manual" section

In addition to activation, the modem data profile provisioning is done using a process called IOTA. IOTA is initiated automatically when you use the cellular cdma activate manual command.

Here is a sample output from this command:

router#cellular 0/0/0 cdma activate manual 1234567890 1234567890 1234 12 12345 

NAM 0 will be configured and will become Active

Modem will be activated with following Parameters 

MDN :1234567890; MSID :1234567890; SID :1234; NID 12:

Checking Current Activation Status

router#

*Feb  6 23:29:08.459: IOTA Status Message Received. Event: IOTA Start, Result: SUCCESS

*Feb  6 23:29:08.459: Please wait till IOTA END message is received

*Feb  6 23:29:08.459: It can take up to 5 minutes

*Feb  6 23:29:27.951: OTA State = SPL unlock, Result = Success

*Feb  6 23:29:32.319: OTA State = Parameters commited to NVRAM, Result = Success

*Feb  6 23:29:40.999: Over the air provisioning complete; Result:Success

*Feb  6 23:29:41.679: IOTA Status Message Received. Event: IOTA End, Result: SUCCESS

---

Note 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.

---

---

Tip A periodic refresh of the data profile may be needed as required by your carrier. Use the following command to refresh the data profile: cellular cdma activate iota.

---

Activating Using OTASP

To provision and activate your modem using OTASP, use the following command beginning in EXEC mode:

cellular slot/wic_slot/port cdma activate otasp phone_number

---

Note You need to obtain the phone number for use with this command from your carrier. The standard OTASP calling number is *22899.

---

Data Call Set up

To set up a data call, use the following procedures:

•Configuring the Cellular Interface

•Configuring DDR

•Configuring DDR Backup

Figure 5 shows a data call setup using the 3G wireless HWIC.

Figure 5 Data Call Setup with the HWIC-3G-CDMA

Configuring the Cellular Interface

To configure the cellular interface, enter the following commands in the cellular interface mode.

SUMMARY STEPS

1. configure terminal

2. interface cellular <slot/wic/port>

3. encapsulation ppp

4. ppp chap password 0 <password>

5. asynchronous mode interactive

6. ip address negotiated

---

Note The modem supports both mobile IP (MIP) and simple IP (SIP). In both modes, the modem authenticates with the network. However, when the modem is configured in MIP-preferred mode (ask your carrier which mode is supported), if MIP authentication fails, the modem tries to set up a SIP call. The modem uses SIP authentication parameters derived during modem provisioning and passes the CHAP authentication challenge to the cellular interface. The purpose of the authentication challenge is to keep the cellular interface informed of Link Control Protocol (LCP) negotiations between the modem and the network. The authentication challenge from the modem does not have a username, so under the cellular interface, you should configure a default CHAP password, i.e., configure only the ppp chap password and not the ppp chap hostname. If your carrier supports only MIP, you do not need to configure either of the two parameters.

---

DETAILED STEPS

	Command or Action	Purpose
Step 1	Router# configure terminal Example: Router# configure terminal	Enters global configuration mode from the terminal.
Step 2	Router(config)# interface cellular <slot/wic/port> Example: Router (config)# interface cellular 0/0/0	Specifies the cellular interface.
Step 3	Router(config-if)# encapsulation ppp Example: Router (config-if)# encapsulation ppp	Specifies PPP encapsulation for an interface configured for dedicated asynchronous mode or dial-on-demand routing (DDR).
Step 4	Router (config-if)# ppp chap password <password> Example: Router (config-if)# ppp chap password cisco	Defines an interface-specific CHAP password. Note You can set the password to any value. This password is used only when the modem has failed MIP authentication and fails over to SIP mode. The modem ignores the CHAP authentication response from the cellular interface.
Step 5	Router(config-if)# async mode interactive Example: Router (config-if)# async mode interactive	Returns a line that has been placed into dedicated asynchronous network mode to interactive mode, thereby enabling the slip and ppp EXEC commands.
Step 6	Router(config-if)# ip address negotiated Example: Router (config-if)# ip address negotiated	Specifies that the IP address for a particular interface is obtained via PPP/IPCP address negotiation.

---

Note When static IP address is required for the cellular interface, the address may be configured as ip address negotiated. During IPCP, the network ensures that the correct static IP address is allocated to the device. If a tunnel interface is configured with ip address unnumbered <cellular interface>, it is necessary to configure the actual static IP address under the cellular interface, in place of ip address negotiated. For a sample cellular interface configuration, see "Basic Cellular Interface Configuration: Example" section.

---

Configuring DDR Backup

To monitor the primary connection and initiate the backup connection when needed, the router can use one of the following methods:

•Backup Interface—The backup interface that stays in standby mode until the primary interface line protocol is detected as down and then is brought up.

•Floating Static Route—The route through the backup interface has an administrative distance that is greater than the administrative distance of the primary connection route and therefore would not be in the routing table until the primary interface goes down.

•Dialer Watch—Dialer watch is a backup feature that integrates dial backup with routing capabilities.

Configuring Interfaces to Use a Backup Interface

To configure one or more interfaces to use a backup interface, use the following commands, beginning in global configuration mode.

SUMMARY STEPS

1. interface type number

2. backup interface cellular number

Step 3	Router(config-if)# backup delay enable-delay disable-delay Example: Router(config-if)# backup delay enable delay	Specifies delay between the physical interface going down and the backup interface being enabled, and between the physical interface coming back up and the backup being disabled.

---

Note You cannot configure a backup interface for the cellular interface and any other asynchronous serial interface.

---

Configuring DDR Backup Using Dialer Watch

To initiate dialer watch, you must configure the interface to perform DDR and backup. Use traditional DDR configuration commands, such as dialer maps, for DDR capabilities.

Modem Firmware Upgrade

The 3G wireless HWIC has an embedded modem from Sierra Wireless (MC5725). The modem firmware can be upgraded by using Cisco IOS commands. The firmware is packaged in a tar distribution file and can be downloaded from the wireless software download page on Cisco.com. Use the following procedure to upgrade the modem firmware:

---

Caution Before upgrading the modem to a new firmware version, please check whether the new firmware version has been certified by your wireless service provider. Using an uncertified firmware version on the modem may affect the wireless service provider network adversely.

---

Refer to the following website for the latest certified firmware version for your carrier and IOS compatibility:

http://www.cisco.com/en/US/products/hw/routers/networking_solutions_products_generic_content0900aecd80601f7e.html

SUMMARY STEPS

1. Go to the Cisco Wireless WAN software download website at:

http://tools.cisco.com/support/downloads/go/Redirect.x?mdfid=278875243

2. Download the appropriate CDMA firmware release under Wireless Integrated Switches and Routers.

3. Use the archive command to extract the firmware distribution into the router flash memory:

archive tar /xtract source-url destination-url

4. Use the following command to initiate the firmware upgrade process:

microcode reload cellular pa-bay slot cdma modem-provision

DETAILED STEPS

	Command or Action	Purpose
Step 1	Go to the Cisco Wireless WAN software download website at http://tools.cisco.com/support/downloads/go/Redirect.x?mdfid=278875243	Provides access to Cisco Wireless WAN software downloads. Select firmware for Cisco 3G wireless HWIC. Note This website is only available to registered Cisco.com users.
Step 2	Download the appropriate CDMA firmware release under Wireless Integrated Switches and Routers.	Downloads the modem firmware package to a TFTP/FTP server that is accessible from the router in which the 3G wireless HWIC is installed.
Step 3	router# archive tar /xtract source-url destination-url Example: Router# archive tar /xtract tftp://192.168.1.1/MC5725_00_57_00_vzw_package.t ar flash:	Uncompresses the files of the modem firmware package and copies them to a location that is accessible by the router in which the 3G wireless HWIC is installed. source-url—URL of the source location with the firmware TAR filename. Valid URLs can refer to TFTP or HTTP servers or to router flash memory. destination-url—URL of the destination where the tar file would be extracted. Use router flash.
Step 4	router# microcode reload cellular pa-bay slot cdma modem-provision	Initiates the firmware upgrade process. pa-bay—Use 0 for HWIC. slot—Slot number where the HWIC is plugged in. Note This command requires the cellular interface to be in administrative shutdown mode. The firmware upgrade process may take up to 15 minutes, during which the modem is inaccessible.

---

Caution Do not disconnect power or switch the router off during the firmware upgrade process. Either action may result in permanent modem failure.

Troubleshooting Tips

If you are encountering issues with the working of the 3G wireless HWIC, this section will help you troubleshoot and pinpoint the cause of failure.

Verifying Configuration

To verify your configuration and to make sure that your connection is up and running, follow these step:

---

Step 1 After creating a profile with the create cellular profile command, send a ping from a router or attached host.

Step 2 If you do not get any response, to find where failure is occurring, run the following debug commands:

•debug chat script

•debug PPP negotiation

•show cellular all

•show interface cellular

•show running-config

•show controllers cellular

Step 3 Save the output from all these commands and contact your system administrator.

---

Checking Signal Strength

If the RSSI level is very low, for example, less than -110 dBm, it means one of the following:

•Your antenna is not connected

•The antenna is not working properly

•There is no service in your area

If all the above are connected and working as they should, contact your system administrator.

Call Setup Using CHAT Script

The following is a sample output for a call that is set up using CHAT script. It shows a received IP address from the network and indicates that the call setup is successful and the data path is open:

Modem Troubleshooting Using the Diagnostic Port

The RJ-45 port on the faceplate of the 3G wireless HWIC provides access to the debug port on the Sierra Wireless modem. By connecting an industry-standard diagnostic tool, such as Qualcomm CAIT/QXDM or Spirent UDM to this port, you can perform radio-level diagnostics and traffic monitoring on the modem. Use the following test command to turn diagnostics on:

router# test cell-hwic slot/port/wic dm-port on

The cable used to connect the PC/Laptop running the diagnostic tool is the standard Cisco router console cable (RJ-45 to DB-9).

---

Note To enable test commands, you must enter the service internal command in the global configuration mode.
