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

Table 2 3G Wireless HWIC (GSM) 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.
UMTS	UMTS is the active service.
HSDPA	HSDPA is the active service.
Note Both UMTS and HSDPA Off: Fallback (EGDE or GPRS) service is active. 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 wireless HWIC automatically selects the best available connection.

The 3G wireless HWIC provides the following software functionality:

•Modem activation—You can activate the modem by using Cisco IOS commands.

•Modem management—You can access modem software and hardware information, radio and network status, and data profile information by 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 WAN 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 fallback-mode connection when the primary connection is available.

•Automatic teardown—After a configurable timeout, 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) and the router establishes a connection with the nearest cell infrastructure automatically. This is different from the mobile capability that cell phones offer.

•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.

•You must subscribe to a service plan with a wireless service provider and obtain a SIM card from the service provider.

•You must install the SIM card before configuring the 3G Wireless HWIC. For instructions on how to install the SIM card, see Chapter 13 in the Cisco Interface Cards Hardware Installation Guide at the following URL: http://cisco.com/en/US/products/hw/modules/ps2641/products_module_installation_guide_book09186a0080692b21.html

•You must install the required antennas before you configure the 3G 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 check your LEDs for signal reception as described in Table 2.

•You should be familiar with the Cisco IOS software , beginning with Release 12.4(11)XV or later for Cisco HWIC 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)

Restrictions for Configuring the 3G Wireless HWIC

The following restrictions apply to configuring the Cisco Wireless HWICs:

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

•Throughput—due to the shared nature of wireless communications, the experienced throughput varies depending on the number of active users or congestion in a given network.

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

•VoIP is not currently supported.

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

Overview of GSM/UMTS Data Network

The Global System for Mobile Communications (GSM) is the most widely deployed cellular network in the world. It is based on the specification from European Telecommunications Standards Institute (ETSI). GSM was primarily designed for voice and was circuit switched but due to the popularity of cellular networks and the great demand for data services, GPRS was introduced as a packet switched data overlay over the GSM radio network. The radio and network resources of GPRS are accessed only when data actually needs to be transmitted between the GPRS mobile user and the GPRS network.

GPRS introduced several new network nodes into the GSM architecture for packet switching, they form the Mobile Packet Core. The Mobile Packet Core includes the Serving GPRS Support Node (SGSN) and the GPRS Gateway Support Node (GGSN). The SGSN is the node which in some ways carries out the same function as the Foreign Agent in Mobile IP. It tunnels IP packets towards the GGSN and detunnels packets back from the GGSN. It also carries out mobility managed and billing. The GGSN is the node which carries out the role in GPRS equivalent to the Home Agent in Mobile IP. The GGSN provides the connectivity to the IP network and the SGSN. It is responsible for IP address assignment and is the default router for the connected User Equipment (UE).

Figure 2 shows a GSM network and the network elements it contains.

Figure 2 GSM Network Overview

The Base Tranceiver Station (BTS) and Base Station Controller (BSC) are located at the Cell site and are the common nodes for both voice and data services. They provide the radio or the physical layer connectivity between the mobile user and the mobile network. As the BSC voice and data traffic get segregated, the voice traffic goes to the Mobile Switching Center (MSC), while the data traffic is sent to the GGSN. From the GGSN, the data packets either go directly to the internet or they can be backhauled to the customer data center for a VPN connection.

UMTS is a 3G wireless system that delivers high-bandwidth data and voice services to mobile users.UMTS evolved from GSM. UMTS has a new air interface based on Wideband Code Division Multiple Access (W-CDMA) and an IP core network based on general-packet radio service (GPRS). The nodes in a UMTS network are almost the same as in a GSM/GPRS network. BTS and BSC have been renamed to Node B and Radio Network Controller (RNC), respectively. UMTS addresses the growing demand of mobile and Internet applications for new capacity in the overcrowded mobile communications sky. The new network increases transmission speed to 2 Mbps per mobile user and establishes a global roaming standard.

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.

Troubleshooting

This section provides the necessary background information and resources available for troubleshooting the Cisco 3G wireless HWIC.

Verifying Data Call Setup

To verify the data call setup, follow these steps:

---

Step 1 After you create a modem data profile cellular profile create command and configuring DDR on the cellular interface, send a ping from the router to a host across the wireless network.

Step 2 If the ping fails, debug the failure by using the following debug and show commands:

•debug chat

•debug dialer

•debug ppp negotiation

•show cellular all

•show interface cellular

•show running-config

•show ip route

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

---

Checking Signal Strength

If the Received Signal Strength Indication (RSSI) level is very low (for example, if it is less than -110 dBm) follow these steps:

---

Step 1 Check the antenna connection. Make sure the TNC connector is correctly threaded and tightened.

Step 2 If you are using a remote antenna, move the antenna cradle and check if the RSSI has improved.

Step 3 Contact your wireless service provider to verify if there is service availability in your area.

---

Verifying Service Availability

The following is a sample output for the show cellular all command for a scenario where the antenna is disconnected and a modem data profile has not been created. The errors in this case have been highlighted with >>>>>>>:

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 like 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.

Modem Settings for North America and Carriers Operating on 850 MHz and 1900 MHz Bands

For HWIC-3G-GSM deployments in North America and for carriers operating in the 850MHz and 1900 MHz bands, the following changes to the modem settings are required to prevent long network attach times.

The output of show cellular x/x/x all command shows the following:

•No network attach

•RSSI value is -110 dB

•Band selection is set to AUTO

Changing Modem Settings

To change the modem settings to force the modem to scan NA (North American) bands only, follow these steps:

---

Step 1 Change the PRL region to '2' (the default is 1). To do this, follow the procedure in "Changing the PRL Region on the Modem" section.

Step 2 Set the band to WCDMA/GSM NA using the following Cisco IOS command:

router# cellular 0/0/0 gsm band wcdma-gsm-na

---

Prerequisites

Before you change the PRL region, you must ensure that:

•The interface is in a shutdown mode before the chat-script is executed.

•Interface is un-shut for normal operation after the chat-script is executed.

•You must run the chat-script only once.

Changing the PRL Region on the Modem

To change the PRL region on the modem, follow these steps:

---

Step 1 Go to the configuration mode of the router and configure the PRL change chat-script. The following is an example using "prl" as the name of the chat script and "02" specifying the PRL region:

Router# conf t

Router(config)# chat-script prl "" "at" TIMEOUT 5 "OK" AT!ENTERCND="A710" TIMEOUT 5 "OK" 
AT!CUSTOM="PRLREGION",02 TIMEOUT 5 "OK" "AT!RESET"

---

Note The entire chat script command must be entered in one line. Copy and paste it from this document to avoid typing errors.

---

Step 2 Shut down the cellular interface by entering the shut command in the configuration mode:

In the following example, 0/0/0 is a sample interface number. Replace it with the correct interface number based on the slot in which the 3G HWIC is plugged in.

Router(config)#interface cellular 0/0/0

Router(config-if)#shut

Step 3 Exit the configuration mode.

Router(config-if)#exit

Step 4 To execute the chat-script, enter the start-chat prl command. In the following example, "prl" is the name of the chat script and 0/0/0 is the corresponding slot/port number that the cellular HWIC is plugged into.

Router#start-chat prl 0/0/0 

Enabling "debug chat" and monitoring the console logs will indicate whether the chat-script executed successfully. For example,

Router#config t

Router(config)#logging enable

Router(config)#exit

Router#debug chat

Step 5 Un-shut the cellular interface once the chat-script is over by entering the no shut command in the configuration mode:

Router#conf t

Router(config)#interface cellular 0/0/0

Router(config-if)#no shut

Below is a sample output after the debugs are enabled for a successful PRL change after invoking the chat-script:

	Router#start-chat prl 0/3/0

	Router#
