The MC8705 modem supports the following GSM features:

- Cellular packet data profile

- Traditional modem COM port support for CSD and AT commands (concurrent with NDIS)

- Suspend/resume

- SIM application tool kit with proactive SIM commands

- Static and Dynamic IP address. The network may assign a fixed IP address or dynamically assign one using Dynamic Host Configuration Protocol (DHCP).

SIM Interface

The 3G GSM module has two GSM SIM card sockets for storing critical subscriber authentication information. The SIM card can be installed in either of the two available sockets accessible on the front panel of the 3G module. Only one slot is active at any given time—if both slots SIM0 and SIM1 are occupied by a card, then the system activates SIM0.

When the Dual SIM feature is enabled (the default), SIM0 is the primary slot and SIM1 is the secondary (failover) slot. If SIM0 loses connectivity to the network, the system automatically switches to SIM1.

- The SIM card stores critical GSM subscriber authentication information.

- The two SIM cards are powered by the modem and operate at 5 MHz.

- The SIM card is a 3.3 V device, and it has 2.8 V power applied to its power pin.

Through the software you can control which SIM is connected to the modem. Only one SIM can be connected to the modem at any time. The SIM switching circuit also provides the option of disconnecting both SIMs from the modem. The 3G Debug and SIM Control register controls the SIM connections.

By setting the SIM Socket Enable and the SIM Socket Select bit, you can control the signal and power connections from the modem to the SIM card.

Table 9 shows the options used to connect to SIM0 and SIM1 cards:

Module Power States

The module has the following power states:

- Normal mode (default mode)—Module is active. Receive and Transmit modes are possible. In this state:

– The module is fully powered.

– The module is capable of placing/receiving calls or establishing data connections on the wireless network.

– The USB interface is fully active.

Note The module unit defaults to the Normal state when VCC is first applied.

- Low power mode (airplane mode)—The module is active, but RF is disabled. In this state, RF (both Rx and Tx) is disabled on the module, but the USB interface is still active. This state is controlled though the host interface by the following software commands:

– +CFUN=0 command (AT Command Set for User Equipment (UE) (Release 6))

– CNS_RADIO_POWER [0x1075] (MC87XX Modem CnS Reference (Document 2130602))

– Disable Modem command (MC87XX Modem CnS Reference (Document 2130602))

Note The module goes from normal mode into low-power mode to suspend RF activity. This occurs when the module’s supply voltage exceeds either the high or low limits. The module returns to normal mode to resume RF activity. It occurs when the module’s supply voltage returns from critical to normal limits.

- Disconnected mode —No power to the module. The host power source is disconnected from the module and all voltages associated with the module are at 0 V.

CGR 1120 and CGR 1240 control the power to the module, therefore the host can stay powered on and cut the power in order to put the module into the disconnected state.

The module begins a shutdown sequence and powers off if it has been in a powered-on state for more than 10.5 seconds and the host device drives the W_Disable# signal low for:

- MC8775/MC8775V: > 50 ms

- Other devices: > 500 ms

Installing and Removing the SIM Card

For more information on the SIM interface, see SIM Interface.

Note You must reload the system after installing or changing the SIM card.

Preventing Electrostatic Discharge Damage

Electrostatic Discharge (ESD) damage can occur when electronic cards or components are handled improperly, which can result in complete or intermittent failures.

To prevent ESD damage:

- Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.

- Connect the equipment end of the strap to an unfinished chassis surface.

- Place a removed compact SIM card on an antistatic surface or in a static shielding bag. If the card will be returned to the factory, immediately place it in a static shielding bag.

- Avoid contact between the card and clothing. The wrist strap protects the card from ESD voltages on the body only; ESD voltages on clothing can still cause damage.

- Do not remove the wrist strap until the installation is complete.

Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

Statement 1030

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms (Mohms).

UMTS/GSM Data Network Overview

The Global System for Mobile Communications (GSM) is the most widely deployed cellular network in the world. It is based on the specification from the 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 tunnels IP packets towards the GGSN and detunnels packets back from the GGSN. It also carries out mobility management and billing. 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 5 shows a GSM network and the network elements it contains.

Figure 5 GSM Network Overview

The Base Transceiver 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 an 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 renamed as 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 UMTS network increases transmission speed to 2 Mbps per mobile user and establishes a global roaming standard.

High-Speed Packet Access (HSPA) is a collection of two mobile protocols - High-Speed Downlink Packet Access (HSDPA) and High-Speed Uplink Packet Access (HSUPA), that extends and improves the performance of existing WCDMA/UMTS protocols. HSDPA and HSUPA provide increased performance by using improved modulation schemes and by refining the protocols by which 3G modem and base stations communicate. These improvements lead to a better utilization of the existing radio bandwidth provided by WCDMA. HSPA improves the end-user experience by increasing peak data rates of up to 14 Mbit/s in the downlink and 5.76 Mbit/s in the uplink. It also reduces latency and provides up to five times more system capacity in the downlink and up to twice as much system capacity in the uplink, reducing the production cost per bit compared to original WCDMA protocols.

3G Cellular WAN MIB

This section describes the MIB definition and implementation support for Cisco cellular 3G WAN products on the customer premises equipment (CPE) end.

The 3G Cellular WAN MIB supports both CDMA and GSM set of cellular standards and includes the following technologies:

- GSM—GPRS/EDGE/UMTS/HSPA

- CDMA—1xRTT/EVDO Rev0/RevA

The 3G cellular MIB uses indexes from the cellular interface and from the modem. You can obtain the interface index using IF-MIBs and the modem index using the ENTITY MIBs.

The 3G MIB definition includes the following major sub-trees:

- Common objects

- CDMA objects

- GSM objects

- Traps or notifications

You can use MIB object c3gStandard defined in the c3gWanCommonTable to distinguish between CDMA or GSM and implementing MIB for CDMA or GSM.

Note Cisco 3G MIB supports all SNMP versions including V1, V2, V2C, and V3. For more information about SNMP, see the SNMP Software Configuration Guide for Cisco 1000 Series Connected Grid Routers (Cisco IOS).

At a high level architecture, the Cisco 3G WAN MIBs are divided into two groups and have the following structure:

1. ciscoWan3gMIBNotifs—this group defines all the trap events for Cisco 3G WAN MIBs

2. ciscoWan3gMIBObjects—this group defines all the MIB objects for Cisco 3G WAN MIBs

ciscoWan3gMIBObjects

The ciscoWan3gMIBObjects group has three sub-groups:

– c3gWanCommonTable—defines the common MIB objects for both CDMA and GSM.

– c3gWanCdma—defines the MIB objects specific for CDMA set of standards (3GPP2).

– c3gWanGsm—defines the MIB objects specific for GSM set of standards (3GPP).

Under c3gWanGsm, there are five sub-groups:

- c3gGsmIdentityTable for GSM user identity related objects.

- c3gGsmNetworkTable for GSM network related objects.

- c3gGsmPdpProfile for GSM PDP profile related objects.

- c3gGsmRadio for GSM radio related objects.

- c3gGsmSecurityTable for GSM security related objects.

ciscoWan3gMIBNotifs

Cisco Cellular 3G WAN MIB implementation supports SNMP GET (read operation) for all MIB objects, and SNMP SET (write operation) for the following RW (read-write) objects, including:

- c3gRssiOnsetNotifThreshold

- c3gRssiAbateNotifThreshold

- c3gEcIoOnsetNotifThreshold

- c3gEcIoAbateNotifThreshold

- c3gModemTemperOnsetNotifThreshold

- c3gModemTemperAbateNotifThreshold

- c3gModemReset

- c3gModemUpNotifEnabled

- c3gModemDownNotifEnabled

- c3gServiceChangedNotifEnabled

- c3gNetworkChangedNotifEnabled

- c3gConnectionStatusChangedNotifFlag

- c3gRssiOnsetNotifFlag

- c3gRssiAbateNotifFlag

- c3gEcIoOnsetNotifFlag

- c3gEcIoAbateNotifFlag

- c3gModemTemperOnsetNotifEnabled

- c3gModemTemperAbateNotifEnabled

Note By default, all notifications are disabled. To view notifications, you must enable these notifications (see Table 12).

Note The IF MIBs also have notifications for the cellular interface objects that are used in conjunction with the notification type. When you get a notification, you must check the associated objects.

Table 11 shows various notifications and what they mean.

Table 11 Notifications

Notifications

Details

ModemUpNotification

The modem was successfully recognized.

ModemDown

This section covers the following topics:

- Prerequisites

- Restrictions and Limitations

- Data Account Provisioning

- Data Call Setup

- Basic Cellular Interface Configuration

Note The 3G module can be plugged into slot 3 of the Cisco 1120 Connected Grid Router and Cisco 1240 Connected Grid Router. Therefore, the interface name used to configure the module can be 3/1. Interface 3/1 is used in the configuration examples in this section.

Prerequisites

To configure the 3G GSM module, you must meet the following requirements:

- Have 2G/3G network coverage where your router will be physically located. For a complete list of supported carriers, see the product data sheet.

- Subscribe to a service plan with a wireless service provider and obtain a SIM card.

- Install the SIM card before configuring the 3G GSM module. For instructions on how to install the SIM card, see the section, Installing the SIM Card.

- You must install the required antennas before you configure the 3G GSM module. See the Connected Grid Antennas Installation Guide for instructions on how to install the antennas.

- You must check your LEDs for signal reception as described in Table 2 .

- When installing within a Verizon network, be sure that you register the 3G Verizon modem as CGR 1240.

- Contact your ISP to get your access point name.

- You should be familiar with Cisco IOS.

Restrictions and Limitations

The following restrictions apply to configuring the Cisco Connected Grid 3G Module:

- Data connection can be originated only by the module.

- 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.

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

Data Account Provisioning

To provision your data account, follow these procedures:

- Verifying Signal Strength and Service Availability

Configuring the Cellular Interface

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

BEFORE YOU BEGIN

When a 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 type number , 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 the “Basic Cellular Interface Configuration” section.

DETAILED STEPS

Step 2

ip route network-number network-mask { ip-address | interface } [ administrative distance ] [ name name ]

Establishes a floating static route with the configured administrative distance through the specified interface.

Note A higher administrative distance should be configured for the route through the backup interface, so that it is used only when the primary interface is down.

EXAMPLE

Router# configure terminal

Router (config)# ip route 0.0.0.0 Dialer 2 track 234

Configuring Dual SIM

The Dual SIM feature implements auto-switch and failover between two cellular networks on the CGR 1000. This feature is enabled by default with SIM slot 0 being the primary slot and slot 1 being the secondary (failover) slot. Follow this procedure to configure the Dual SIM feature.

BEFORE YOU BEGIN

- For auto-switch and failover to work, configure the SIM profile for slots 0 and 1 using the gsm sim profile command.

- For auto-switch and failover to work, configure the chat script without a specific profile number.

- If no SIM profile is configured, profile #1 is used by default.

- If no GSM failover timer is configured, the default failover timeout is 2 minutes.

- If no GSM SIM primary slot is configured, the default primary SIM is slot 0.

DETAILED STEPS

Command or Action

Purpose

Step 1

configure terminal

Enters global configuration mode from the terminal.

Step 2

gsm failovertimer minutes

Sets the timeout period, in minutes, before the 3G GSM module with dual SIMs fails over to the secondary SIM. The range is from 1 to 7.

The default timeout period is 2 minutes.

Step 3

gsm sim authenticate { 0 | 7 } pin slot number

Stores the SIM CHV1 code for verification.

- Authentication type:

– 0 —Specifies an unencrypted (cleartext) PIN that follows this parameter.

– 7 —Specifies a hidden PIN that follows this parameter.

- pin —A 4 to 8 character code provided by your carrier to lock or unlock the SIM card.

- number —Slot number. Either 0 or 1.

Note This command works only when the SIM is locked. If you enter it incorrectly several times, the SIM is blocked. To avoid this, when CHV1 verification fails, you must re-enter the CHV1 code to initiate verification.

Step 4

gsm sim max-retry retries

Specifies the maximum number of times the switchover between the two SIM cards can occur.

The range for retries is 0-65535.

Every time a SIM switchover occurs, a counter is incremented until it reaches the maximum number of switchover attempts. Then, service is tied to one SIM (the primary SIM) and automatic SIM switchover is stopped. To see the number of switchover attempts, use the show cellular 0 security command.

Setting the number of retries to 0 disables the automatic switchover and keeps the service tied to one SIM (the primary SIM).

The default is 10.

Step 5

gsm sim primary slot number

Sets a SIM slot to be the primary slot.

- number —Slot number. Either 0 or 1.

By default, slot 0 is the primary slot.

Step 6

gsm sim profile profile-id slot number

Configures the SIM profile.

- profile-id —Profile number (a value from 1 to 16).

- number —Slot number. Either 0 or 1.

To create a profile, use the cellular gsm profile create command. For more information, see Configuring a Modem Data Profile.

EXAMPLE

This example shows how to set the SIM switchover timeout period to 3 minutes:

router# configure terminal

router(config-controller)# gsm failovertimer 3

This example shows how to authenticate using an unencrypted pin:

router(config-controller)# gsm sim authenticate 0 1234 slot 0

This example shows how to set the maximum number of SIM switchover retries to 20:

router(config-controller)# gsm sim max-retry 20

This example shows how to set SIM slot 1 as the primary slot:

router(config-controller)# gsm sim primary slot 1

This example shows how to configure the SIM card in slot 0 to use profile 10:

router(config-controller)# gsm sim profile 10 slot 0

Troubleshooting

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

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 cellular interface-id messages callcontrol

- show cellular interface-id 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 interface-id 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 Settings for North America and Carriers Operating on 850 MHz and 1900 MHz Bands

For 3G GSM module 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 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 3/1 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, 3/1 is a sample interface number. Replace it with the correct interface number based on the slot in which the 3G GSM module is plugged in.

Router(config)#interface cellular 3/1

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 3/1 is the corresponding slot/port number that the cellular 3G module is plugged into.

Router#start-chat prl 3/1

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 3/1

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 3/1

Retrieving the Electronic Serial Number

If your network provider requests the 11-digit decimal equivalent of your Electronic Serial Number (ESN), you must retrieve your ESN, then convert it to decimal notation. See Converting Hexadecimal ESN to Decimal Notation.

The ESN number is located directly on the modem label in hexadecimal notation. It can also be retrieved using the Cisco IOS CLI using the show cellular 3/1 all command.

The sample output below shows the IMEI number:

CGR1K# show cellular 3/1 all

Converting Hexadecimal ESN to Decimal Notation

If your network provider requests the 11-digit decimal equivalent of your Electronic Serial Number (ESN), you must retrieve your ESN, then convert it to decimal notation. See Retrieving the Electronic Serial Number.

To convert the ESN number from hexadecimal notation to decimal notation, follow this procedure:

Step 1 Start with the 8-digit HEX ESN # obtained from the label or using CLI, for example 0x603C9854. This number consists of two parts:

- 0x60—Serial number

- 3C9854—Manufacturer’s code

Step 2 Convert manufacturer’s code to decimal as shown:

Hexadecimal 0x60 equals decimal 96.

If decimal value is two digits only, prepend it with a zero to expand it to three digits.

Manufacturer’s code is thus 096.

Step 3 Convert the serial number to decimal, as shown in the example below:

Hexadecimal 0x3C9854 equals decimal 3971156.

If decimal value is less than 8 digits, add enough zeros to make it into an 8 digit number.

Serial number is thus 03971156.

Step 4 To obtain complete 11-digit decimal ESN notation, combine manufacturer code and serial number:

Manufacturer code: 096

Serial #: 03971156

Decimal ESN: 09603971156
