The MC5728V Mini Card supports communication with the host through the USB interface. The USB
interface can be dynamically configured to operate in one of two modes:
• Non-MUX mode
• MUX mode
The MC5728V Mini Card supports three logical interfaces:
• Data channel—Supports AT command and PPP packet exchange during data calls
• Control channel—Supports modem control and status, call processing, and event notification
• Diagnostic channel—Supports the QUALCOMM Diagnostic Monitoring protocol used by support
tools
GSM Module SIM Interface
Two adjacent SIM sockets (SIM1 and SIM2) are available on the card. The SIM card stores critical GSM
subscriber authentication information.
The two SIM cards are powered by the modem and operates at 5 MHz. The SIM card is a 3.3 V device,
and 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 form 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.

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 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.

authentication information. The SIM card can be installed in either of the two available sockets
accessible on the front panel of the Cisco Connected Grid 3G Module.
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, and 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).

Software Overview
UMTS/GSM Data Network Overview
Global System for Mobile Communication (GSM) is the most widely used digital mobile phone system
and the de facto wireless telephone standard in Europe. It is based on the specification from European
Telecommunications Standards Institute (ETSI). Originally defined as a pan-European open standard for
a digital cellular telephone network to support voice, data, text messaging and cross-border roaming.
GSM is now one of the world's main 2G digital wireless standards.
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, General Packet Radio Service (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 needs to be transmitted between the GPRS mobile user and the GPRS
network.
GSM models are based on 3GPP, and they support HSPA (High-Speed Uplink Packet Access (HSUPA)
and High-Speed Downlink Packet Access (HSDPA)), UMTS (Universal Mobile Radio Service), EDGE
(Enhanced Data Rates for Global Evolution), and GPRS.
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. GGSN is the node that
carries out the role in the GPRS equivalent to the Home Agent in Mobile IP. The GGSN provides the
connectivity to the IP network and the SGSN, is responsible for IP address assignment, and is the default
router for the connected User Equipment (UE).
Figure 6 shows a GSM network and the network elements it contains.
Figure 6 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

Software Overview
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.
Universal Mobile Telecommunications System (UMTS) evolved from GSM and is a 3G wireless system
that delivers high-bandwidth data and voice services to mobile users. 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 that of 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.
UMTS (Universal Mobile Telecommunication System) (W-CDMA) is standardized by 3GPP and offers
the following:
• W-CDMA radio access technology, in addition to the existing GSM and GPRS radio access
networks.
• W-CDMA uses 5 MHz bandwidth radio carriers. Up to 384kb/s initially. Capable of 2 Mb/s, but not
offered commercial yet.
• HSPA is an upgrade to W-CDMA (includes HSDPA (High Speed Downlink Packet Access) and
HSUPA (High-Speed Uplink Packet Access).
–
HSDPA:Various categories support up to 10 Mb/s
–
HSUPA:uplink speed up to 5.76 Mb/s
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.
CDMA Data Network Overview
The Code Division Multiple Access (CDMA) is a digital cellular network developed to deliver
high-speed and improved wireless data service through increased capacity by allowing users to share a
band of frequencies. CDMA is being adopted by many administrators for cellular networks due to its
greater throughput which is six times that of Time Division Multiple Access (TDMA-) or Frequency
Division Multiple Access (FDMA)-based systems.
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.
A typical CDMA network includes a PDSN and a branch office with the 3G wireless Modular and Fixed
Cisco ISRs. 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.
24
Cisco Connected Grid 3G Module Installation and Configuration Guide
OL-25991-01
Configuring the Module
CDMA technology uses spread radio spectrum transmission with concurrent multiple access by dividing
the spectrum shared by multiple users by using channels using unique codes. These codes are filtered by
the receiver using a correlator that accepts only signals (streams of bits) from the desired code channel.
CDMA also employs graceful signal degradation, multipath resistance, inherent frequency diversity, and
interference rejection.
Evolution-Data Optimized (EVDO), also known as 1xEVDO, is a telecommunications standard that
employs the use of multiplexing, CDMA, and TDMA. EVDO was standardized by 3GPP2
(3rd-Generation Partnership Project 2), the global 3G wireless standard specification, and has been
adopted by many mobile service providers who had been previously using CDMA. 1x EVDO
(1x Evolution Data Optimized) supports up to 2.4 Mb/s downlink and 153.6 Kb/s uplink in Revision 0,
while Revision A supports 3.1 Mb/s downlink and 1.8 Mb/s uplink.
CDMA2000, also known as CDMA2000 1x and as 1xRTT (1 times Radio Transmission Technology),
had evolved from IS-95 (cdmaOne), the first CDMA-based digital cellular (2D) standard, with which
CDMA2000 is backward-compatible. The suffix 1x means that it uses the same 1.25 MHz bandwidth as
IS-95 has always used and supports up to 144 Kb/s, initially. CDMA2000 was standardized by the
3GPP2 committee and is based on the standards of CDMA2000 1X, CDMA2000 EVDO Rel. 0,
CDMA2000 EVDO Rev. A, and CDMA2000 EVDO Rev. B.
The Cisco Connected Grid Module—3G EVDO Rev A/0/1xRTT module is based on 3GPP2 and
supports the CDMA2000 EVDO Rev A and Rel. 0, and CDMA2000 1x operating standards.

Configuring the Module
Router# configure terminal
Step 3 Create a chat script using the chat-script command and assign it to your profile:
Router(config)# chat-script <chat-script name> PROFILE1 #
Step 4 Configure dialer parameters on the interface by using the interface command to enter interface
configuration mode, and the dialer command to configure persistent dialer mode.
Router(config)# interface dialer 1
Router(config-if)# dialer pool 1
Router(config-if)# dialer string <chat-script name>#
Router(config-if)# dialer persistent
Step 5 Configure cellular parameters on the interface by using the interface and dialer commands:
Router(config)# interface cellular 3/1
Router(config-if)# dialer pool-member 1
Step 6 Shutdown and no shut the interface using the shutdown and no shutdown commands:
Router(config)# interface cellular 3/1
Router(config-if)# shutdown
Router(config-if)# no shutdown
GSM Dialer Persistent Unconfiguration
All commands can be unconfigured with the no option, however, the dialer persistent configuration
condition cannot be unconfigured. Therefore, to remove dialer persistent, the profile must be deleted
with the cellular configuration command as follows:
Router# cellular 3/1 gsm profile delete 1
CDMA Cellular Interface Configuration
The following example shows how to configure the cellular interface:
Step 1 Configure a chat script using the chat-script command:
Router(config)# chat-script <chat-script name> ATDT#777 <-- ATDT777# is the chat-script name.
Step 2 Configure dialer parameters by using the dialer command:
Router(config)# interface dialer 1
Router(config-if)# dialer pool 1
Router(config-if)# dialer string ATDT777#
Router(config-if)# dialer persistent
Step 3 Configure PPP encapsulation by using the feature command:
Router(config)# feature ppp
Step 4 Configure the cellular parameters by using the encapsulation command:
Router(config)# interface cellular 3/1
Router(config-if)# dialer pool-member 1
Router(config-if)# encapsulation ppp
Step 5 Save changes by issuing shutdown and no shutdown on the interface:

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 also, Converting
Hexadecimal ESN to Decimal Notation, page 42.
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.

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 also, Retrieving the
Electronic Serial Number, page 41.
To convert the ESN number from hexadecimal notation to decimal notation:
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 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 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
