Power Specifications

The 4G LTE module has a 12V power rail and 3.3V stand-by power provided by the host system. It has two 3.3V DC-DC converters on the 12V power rail: one for the module and the other for the modem. You can configure a power margin for the converters with CLI commands.

The modem on the 4G LTE module is powered by the 12v to 3.3v DC-DC converter with 3 Amp maximum current output. The enable pin is driven by a general-purpose input/output (GPIO) and controlled by software. The input is the 12V rail from the host. The output is a regulated 3.3V supply for the wireless modem. It must be able to supply current at an average of 0.8A with spikes up to 2.5A. The duty cycle of the absolute worst case load (during some periods of GSM transmit) is 2.5A @ 25% of the time and 0.2A @ 75%.

Note

Power cables are self-shielded; no additional shielding is required.

SIM Interface

Note

We recommend you use an industrialized and ruggedized SIM card that can operate in a-40 degree C to + 105 degree C environment for best performance.

The 4G LTE module has two SIM card sockets for storing critical subscriber authentication information. You can install the SIM card in either of the two available sockets accessible on the front panel. 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. This behavior cannot be reconfigured.

The SIM card stores critical 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 4G Debug and SIM Control register controls the SIM connections.

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

The following table shows the options used to connect to SIM0 and SIM1 cards:

Table 10. Options to Connect to the SIM Sockets
SIM Socket Enable	SIM Socket Select	State
0	—	No SIM connected

Module Power States

The module has the following power states:

Disconnected—There is 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.

The CGR 1000 Series router controls 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.

Off—There is power to the module, but the module is powered off. 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:
Normal (default state)—Module is active. Receive, Transmit, Sleep, and Shutdown 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 defaults to the Normal state when VCC is first applied in the absence of W_Disable# control.

Low power (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.

Note

The module goes from normal state into low-power state 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.

Installing and Removing the SIM Card

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

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).

LTE Overview

The Long Term Evolution (LTE) standard for wireless data communication is developed by the 3GPP (Third Generation Partnership Project). LTE was introduced in 3GPP Release 8, with enhancements in subsequent 3GPP Releases.

4G LTE is the next stage beyond 3G in the 3GPP evolution of wireless communication technologies. LTE transitions from the combined circuit and packet switching network used in the 3G architecture to an all-IP flat architecture. The LTE architecture involves the following major components:

Evolved Universal Terrestrial Access Network (E-UTRAN)—The LTE access network is a network of evolved NodeB (eNB) base stations with no centralized intelligent controller. This distributed network of intelligent base stations reduces the time required for handovers.
Evolved Packet Core (EPC)—User Equipment (UE) (for example, the Connected Grid 4G LTE module) connects to the EPC over E-UTRAN. The EPC connects to external networks and is completely IP-based. As in the access network, the EPC has a flat architecture so that fewer nodes handle traffic, avoiding protocol conversion.

LTE uses Orthogonal Frequency Division Multiplexing (OFDM) and Multiple-Input Multiple-Output (MIMO) functionality in the radio link at the physical layer to provide spectral efficiency and flexibility, high peak data rates, and low latency. The LTE standards specify a theoretical downlink peak data rate of up to 300 Mbps, uplink peak data rate of 75 Mbps, and user plane latency of less than 5 ms.

For more information about LTE and 3GPP mobile broadband standards, go to http://www.3gpp.org/.

Configuring the 4G LTE Module

The module is configured using the system software.

Prerequisites

To configure the 4G LTE module, you must meet the following requirements:

Have 4G LTE 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.
Contact your ISP and get your access point name (APN).
Install the SIM card before configuring the 4G LTE module. For instructions on how to install the SIM card, see the section, Installing the SIM Card.

Guidelines and Limitations

The following guidelines and limitations apply to configuring the 4G LTE module:

Global Positioning System (GPS) and Short Message Service (SMS) are not supported.
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.
The 4G LTE module can be plugged into slots 3 or 6 of Cisco 1240 Connected Grid Router. Therefore, the interface names used to configure the module can be 3/1 or 6/1.
The 4G LTE module can be plugged into slots 3 or 4 of Cisco 1120 Connected Grid Router. Therefore, the interface names used to configure the module can be 3/1 or 4/1.
CGM-4G-LTE-MNA is not compatible with CGR 1120, CGM-4G-LTE-MNA-AB is compatible with both platforms.

Note

In command syntax, the LTE cellular interface is shown as cellular slot/subslot , where slot refers to the CGR slot where the module resides, and subslot is always 1.

Note

In the following examples, the interface name, including the slot number, is used as an example. Your configuration will vary depending on the slot in which you have installed your 4G LTE module.

Creating, Modifying, or Deleting Modem Data Profiles

The modem data profile contains the data service parameters used to set up a data call. You can create up to 16 data profiles on the Cisco 4G LTE module. The default profile is Profile 1.

Before you begin

Contact your ISP and get your access point name (APN).

Procedure

Step 1	To create an LTE modem data profile, enter the following command in privileged EXEC mode: cellular slot/subslot lte profile create profile-number apn profile-number— A number from 1 - 16. apn— The Access Point Name (APN) for the profile. The APN is provided by your service provider. You can specify only one APN in a profile.
Step 2	(Optional) To delete an LTE profile, enter the following command in privileged EXEC mode: cellular slot/subslot lte profile delete profile-number

Example


4G-CGR1K# cellular 4/1 lte profile create 1 Broadband

Changing Modem Technology Setting

You can restrict or allow the type of LTE technology (auto, GSM, UMTS, or LTE) the modem can use.

Before you begin

Procedure

Step 1	Enter the following Cisco IOS command in privileged EXEC mode: cellular slot/subslot lte technology technology auto—Automatic LTE Technology Selection gsm—GSM lte—LTE umts—UMTS
Step 2	(Optional) To display the LTE technology, use the show cellular slot/subslot radio command.

Example


4G-CGR1K# cellular 4/1 lte technology auto
4G-CGR1K# show cellular 4/1 radio
Radio power mode = ON
Channel Number = 0
Current Band = GSM 900 Extended
Current RSSI = -57 dBm
Current ECIO = -127 dBm
Radio Access Technology(RAT) Preference = AUTO
Radio Access Technology(RAT) Selected = EDGE

Configuring a SIM for Data Calls

The 4G LTE module has two 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 4G LTE module. Only one slot is active at any given time. The software can detect when a SIM card is inserted or removed, and through the software you can control which SIM is connected to the modem. (See Applying a Modem Profile in a SIM Configuration.)

SIM cards can be locked and unlocked:

Service providers usually provide SIM cards in an unlocked state. If the SIM is unlocked, you can insert it into the 4G LTE module and use it without a Personal Identification Number (PIN).
Service providers can also initially lock the SIM with a PIN code (4 to 8 digits long) that they define. Contact your service provider for the PIN code.

The SIM-Lock feature allows you to lock or unlock a SIM with a PIN code so that it is used only in an authorized device. Perform the SIM lock and unlock procedures using the Cisco IOS CLI through a console or Telnet/SSH to the router.

After the SIM is locked, it cannot initiate a call unless authentication is done using the same PIN. During router startup configuration, Cisco IOS performs SIM authentication automatically through configuration of the PIN. After the Cisco IOS configuration is in place, the router can initiate an LTE connection. The router uses the configured PIN to authenticate prior to the LTE connection. If the Cisco IOS PIN configuration is missing or if the PIN is incorrect, the SIM authentication will fail and the connection will not be initiated.

If the locked SIM is moved to a different router or to another device, or if the module in which the locked SIM resides is moved to a different slot in the same router, you need to change the router configuration. The configuration is associated with the cellular controller that is specific to a CGR 1000 Series router module slot number. This ensures that the SIM card will not be used in any unauthorized device, or, if there are multiple 4G LTE modules in a single CGR 1000 Series router, that the appropriate PIN is applied to each 4G LTE module/SIM. You must define an authentication command (with the same PIN used to lock the SIM) on the new device or on the new cellular controller slot to successfully initiate the LTE connection.

Locking and Unlocking a SIM Card Using a PIN Code

Enter the following command in privileged EXEC mode to lock or unlock a SIM card given by your service provider:

Before you begin

Caution

The SIM card gets blocked if the wrong PIN is entered three consecutive times. Make sure you enter the correct PIN the SIM is configured with. If your SIM card gets blocked, contact your service provider for a PIN Unlock Key (PUK) code. Using the PUK code, you can unblock the SIM card.

Procedure

cellular slot/subslot lte sim { lock | unlock } pin

pin is a code (4 to 8 digits long) provided by your carrier to lock or unlock the SIM card.

Example


4G-CGR1K# cellular 4/1 lte sim lock 1111

Changing the PIN Code

Enter the following command in privileged EXEC mode to change the PIN code of a SIM.

Before you begin

SIM should be in locked state when the PIN is being changed.

Procedure

cellular slot/subslot lte sim change-pin pin new-pin

Example


4G-CGR1K# cellular 4/1 lte sim change-pin 1111 1234

Verifying the Security Information of a Modem

To verify the security information of a modem, including the SIM lock status, enter the following command:

Procedure

show cellular slot/subslot security

Example

4G-CGR1K# show cellular 4/1 security

Configuring Automatic Authentication for a Locked SIM

An unencrypted PIN can be configured to activate the Card Holder Verification (CHV1) code that authenticates a modem. Follow this procedure when using an unencrypted Level 0 PIN to configure CHV1. For instructions on how to configure CHV1 using an encrypted Level 7 PIN, see Configuring an Encrypted PIN for a SIM.

Before you begin

A SIM should be locked for SIM authentication to work. To verify SIM status, use the show cellular slot/subslot security command.

Procedure

Step 1

Enter global configuration mode:

configure terminal

Step 2

Specify authentication of the SIM CHV1 code by using an unencrypted (0) keyword and PIN.

lte sim authenticate 0 pin slot { 0 | 1 }

This PIN is sent to the modem for authentication with each subsequent LTE connection. If authentication passes based on the configured PIN, the data call is allowed. If authentication fails, the modem does not initiate the data call.

Note

This command is valid only when an unencrypted PIN is used. To configure CHV1 code using an encrypted PIN, see Configuring an Encrypted PIN for a SIM.

Example


4G-CGR1K# configure terminal
4G-CGR1K(config)# controller cellular 4/1
4G-CGR1K(config-controller)# lte sim authenticate 0 1111 slot 0

Configuring an Encrypted PIN for a SIM

To configure an encrypted PIN, you must first obtain the scrambled value of the PIN. To get the scrambled Level 7 PIN and to configure the SIM CHV1 code for verification using this encrypted PIN, follow this procedure.

Note

When obtaining the encrypted PIN for a SIM, you create a username and password by configuring password encryption, defining the username and associated password, copying the resulting scrambled password, and using this scrambled password in the SIM authentication command. After the scrambled PIN has been obtained and used in SIM authentication, you can delete the username created from the Cisco IOS configuration.

Before you begin

A SIM should be locked for SIM authentication to work. To verify SIM status, use the show cellular slot/subslot security command.

Procedure

Step 1	Enter global configuration mode: configure terminal
Step 2	Enable password encryption: service password-encryption
Step 3	Create a username and password: username name privilege 0 password pin name —Specifies the username. pin —Specifies the four- to eight-digit PIN code.
Step 4	Show the username configuration line with the encrypted level 7 PIN for the username created in step 3. Copy the scrambled password. do show run \| i name
Step 5	Enter cellular controller configuration mode. controller cellular slot/subslot
Step 6	Specify authentication of the SIM CHV1 code by using the encrypted keyword 7 and the scrambled PIN from step 4. lte sim authenticate { 0 \| 7 } pin slot { 0 \| 1 } The PIN is sent to the modem for authentication with each subsequent LTE connection. If authentication passes based on the configured PIN, the data call is allowed. If authentication fails, the modem does not initiate the data call.
Step 7	(Optional) Exit cellular controller configuration mode. exit
Step 8	(Optional) Remove the username and password created in step 3. no username name
Step 9	(Optional) Disable password encryption: no service password-encryption

Example


4G-CGR1K# configure terminal
4G-CGR1K(config)# service password-encryption
4G-CGR1K(config)# username SIM privilege 0 password 1111
4G-CGR1K(config)# do show run | i SIM
4G-CGR1K(config)# controller cellular 4/1
4G-CGR1K(config-controller)# lte sim authenticate 7 055A575E70 slot 0
4G-CGR1K(config-controller)# exit
4G-CGR1K(config)# no username SIM
4G-CGR1K(config)# no service password-encryption

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 stays in standby mode until the primary interface line protocol is detected as down. The backup interface is then brought up.
Dialer Watch—Dialer watch is a backup feature that integrates dial backup with routing capabilities.
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.

Configuring Interfaces to Use a Backup Interface

Follow this procedure to configure the cellular interface as a backup interface.

Before you begin

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

Procedure

Step 1	Enter global configuration mode: configure terminal
Step 2	Specify the interface to be backed up and begin interface configuration mode: interface type number
Step 3	Specify the cellular interface as backup: backup interface cellular slot/subslot
Step 4	Specify the 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. backup delay enable-delay-period disable-delay-period

Example


4G-CGR1K# configure terminal
4G-CGR1K(config)# interface Gi 2/1
4G-CGR1K(config-if)# backup cellular interface 4/1
4G-CGR1K(config-if)# backup delay 0 10

Configuring DDR Backup Using Dialer Watch

To enable dialer watch on the backup interface and create a dialer list, use the following commands in interface configuration mode.

Before you begin

Configure the interface to perform DDR and backup as described in Configuring DDR and Configuring DDR Backup. Use traditional DDR configuration commands, such as dialer maps, for DDR capabilities.

Procedure

Step 1

Enter global configuration mode:

configure terminal

Step 2

Specify the interface:

interface type number

Step 3

Enable dialer watch on the backup interface:

dialer watch-group group-number

Step 4

Enter global configuration mode:

exit

Step 5

Define a list of all IP addresses to be watched:

dialer watch-list group-number ip ip-address address-mask

Step 6

Create a dialer list for traffic of interest and permit access to an entire protocol:

dialer-list dialer-group protocol protocol-name { permit | deny | list access-list-number | access-group }

Step 7

Define traffic of interest.

Note

Do not use the access list permit all command to avoid sending traffic to the IP network. This may result in call termination.

ip access-list access list number permit ip source address

Step 8

Specify the cellular interface:

interface cellular slot/subslot

Step 9

Map a dialer list to the dialer interface:

dialer-group dialer group number

Example


4G-CGR1K# configure terminal
4G-CGR1K (config)# interface Gi 2/1
4G-CGR1K(config-if)# dialer watch-group 2
4G-CGR1K(config-if)# exit
4G-CGR1K(config-if)# dialer watch-list 2 ip 10.4.0.254 255.255.0.0
4G-CGR1K(config)# dialer-list 2 protocol ip permit
4G-CGR1K(config)# access list 2 permit 10.4.0.0
4G-CGR1K (config)# interface cellular 3/1
4G-CGR1K(config-if)# dialer-group 2

Configuring DDR Backup Using Floating Static Route

Follow this procedure to configure a floating static default route on the secondary interface.

Before you begin

Make sure you have ip classless enabled on your router.

Procedure

Step 1

Enter global configuration mode:

configure terminal

Step 2

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

Note

You should configure a higher administrative distance for the route through the backup interface, so that it is used only when the primary interface is down.

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

Example


4G-CGR1K# configure terminal
4G-CGR1K(config)# ip route 209.165.200.225 255.255.255.224 Cellular4/1 253 name name1

Verifying Configuration

To view your configurations and verify the signal strength and service availability on your modem, use the following show commands in privileged EXEC mode:

show ip interface brief
show controller cellular slot/subslot
show interface cellular slot/subslot
show cellular slot/subslot ?
- all —Display consolidated information about the modem, profiles created, radio signal strength, network security, and so on.

Upgrading the Modem Firmware

Follow this procedure to manually upgrade the firmware on the modem of the 4G LTE module. We recommend the manual upgrade process for the LTE modem firmware and Cisco IOS software image for all new deployments and the following existing deployments:

LTE is not the primary CGR WAN interface.
LTE is not the only CGR WAN interface.
The network administrator has out-of-band or local access to the CGR.

Before you begin

Caution

Use only Cisco certified firmware. Using a firmware version not certified by Cisco may impact the wireless service provider network adversely.

Caution

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

Note

Firmware downgrade is not supported.

Note

The module must be operating with 05.05.58 firmware at a minimum. Refer to Feature History for the minimum Cisco IOS software release.

Procedure

Step 1

Go to the Cisco High-Speed WAN Interface Cards software download website at http://software.cisco.com/download/navigator.html .

Note

This website is only available to registered Cisco.com users.

Step 2

Select Cisco Interfaces and Modules > High-Speed WAN Interface Cards.

Step 3

Select the 4G LTE Enhanced High-Speed WAN Interface Card version that you ordered.

The download page for the modem firmware for your module appears.

Step 4

Download the modem firmware file to flash memory on the router.

Step 5

Enter the following command to enable the logging console in privileged EXEC mode:

terminal monitor

Step 6

Initiate the firmware upgrade process:

microcode reload cellular slot/subslot modem-provision flash : filename

Step 7

Verify the firmware upgrade process:

show cellular slot/subslot hardware

Step 8

Reload the Cisco IOS application software image to complete the firmware upgrade:

reload

Note

Ensure that you are reloading the Cisco IOS software image noted in Feature History.

Example


4G-CGR1K# terminal monitor
4G-CGR1K# microcode reload cellular 4/1 modem-provision flash : 
filename
4G-CGR1K# show cellular 4/1 hardware
4G-CGR1K# reload

debug modem	Modem control/process activation

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:

Procedure

Step 1	Check the antenna connection. Make sure the QMA 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 that there is service availability in your area.

Verifying Service Availability

The following are the 4G LTE module service availability issues and their corresponding troubleshooting tasks:


Issues	Troubleshooting
No profile configured	Verify profile. See Configuring the Cellular Interface.
Not connected to the network Antenna not present Antenna bad Out of network	Check antenna hardware for faulty connections. Verify RSSI. Use the show cellular slot/subslot radio command to check the signal strength. SIM card not installed. Use show cellular slot/subslot security command to verify presence of SIM card in a slot and indicated as “green.” Contact your base station for more information.

The following is sample show cellular 4/1 all command output for a scenario where the antenna is disconnected and a modem data profile has not been created.

Modem Troubleshooting Using Integrated Modem DM Logging

Diagnostic Monitor (DM) is a Qualcomm proprietary protocol. Diagnostic software tools, such as Sierra Wireless SwiLog and Qualcomm QXDM, are based on the DM protocol. These tools can be used to capture data transactions between the modem and the network over the RF interface, which makes them useful tools for troubleshooting 3G and 4G data connectivity or performance issues. DM log collection has been integrated into Cisco IOS, eliminating the need for an external PC and simplifying the DM log collection process.

Use the lte modem dm-log command in controller cellular configuration mode to configure integrated DM logging to monitor traffic on the modem. See the Cisco 3G and 4G Serviceability Enhancement User Guide for more information on configuring Integrated DM Logging parameters.

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 4/1 all command.

The sample output below shows the IMEI number:

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:

Procedure

Step 1	Start with the 8-digit HEX ESN # obtained from the label or using the CLI, for example 0x603C9854. This number consists of two parts: 0x60—Serial number 3C9854—Manufacturer’s code
Step 2	Convert the manufacturer’s code to decimal as shown: Hexadecimal 0x60 equals decimal 96. If the 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 the 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 the complete 11-digit decimal ESN, combine the manufacturer code and serial number: Manufacturer code: 096 Serial #: 03971156 Decimal ESN: 09603971156
