Table 2 lists the LEDs and describes their functionality and different states. The LEDs provide a visual

indication of your available services. Please see Installing Cisco Interface Cards in Cisco Access Routers

on Cisco.com for hardware installation details.

The 3G HWIC provides the following software functionality:

•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 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 HWIC tears down the fallback-mode connection

when the primary connection is available.

•Automatic teardown—After a configurable timeout, the 3G HWIC automatically tears down a

connection if there has been no activity.

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

•Profile Configuration—You can configure upto 16 APN profiles.

•SIM Lock/Unlock.

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.

Overview of UMTS/GSM 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

Configuring the 3G Wireless High-Speed WAN Interface Card for Cisco 1841, 1861, and 2800 and 3800 Series Routers (HWIC-3G-GSM and

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 3 shows a GSM network and the network elements it contains.

Figure 3 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

Overview of SNMP MIBs

Simple Management Network Protocol (SNMP) development and use is centered around the

Management Information Base (MIB). An SNMP MIB is an abstract data base, i.e., a conceptual

specification for information that a management application may read and modify in a certain form. This

does not imply that the information is kept in the managed system in that same form. The SNMP agent

translates between the internal data structures and formats of the managed system and the external data

structures and formats defined for the MIB.

The SNMP MIB is conceptually a tree structure with conceptual tables. Cisco 3G MIB is discussed in

more detail in the next section. Relative to this tree structure, the term MIB is used in two senses. In one

sense it is actually a MIB branch, usually containing information for a single aspect of technology, such

as a transmission medium or a routing protocol. A MIB used in this sense is more accurately called a

MIB module, and is usually defined in a single document. In the other sense a MIB is a collection of

such branches. Such a collection might comprise, for example, all the MIB modules implemented by a

given agent, or the entire collection of MIB modules defined for SNMP.

A MIB is a tree where the leaves are individual items of data called objects. An object may be, for

example, a counter or a protocol status. MIB objects are also sometimes called variables.

MIBs can be classified into three categories:

•IF MIBs—describes interface statistics

•Cisco-Entity-Vendortype-OID-MIB.my—ENTITY-MIBs are used to provide general hardware type

for both the HWIC and the modem. CISCO-ENTITY-VENDORTYPE-OID-MIB assigns OIDs for

Cisco components (including the HWICs & the modems). The OIDs are then used as the values of

entPhysicalVendorType in the ENTITY-MIB.

•3G/Wireless MIBs—cellular or wireless-specific MIBs

3G Cellular WAN MIB Architecture

This section describes the MIB definition and implementation support for Cisco's 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 RevA/EVDO RevB

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.

Configuring the 3G Wireless High-Speed WAN Interface Card for Cisco 1841, 1861, and 2800 and 3800 Series Routers (HWIC-3G-GSM and

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.

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).

c3gWanCdma

Under c3gWanCdma, there are seven sub-groups:

•c3gCdmaSessionTable for CDMA session related objects.

•c3gCdmaConnectionTable for CDMA connection related objects.

•c3gCdmaIdentityTable for CDMA user identity related objects.

•c3gCdmaNetworkTable for CDMA network related objects.

•c3gCdmaProfile for CDMA user profile related objects.

•c3gCdmaRadio for CDMA radio related objects.

•c3gCdmaSecurityTable for CDMA security related objects.

c3gWanGsm

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.
