Using Connection
Profiles
The Modem Manager software you have installed with your Merlin for GPRS PC
Card modem may be preconfigured with one or more Connection Profiles.
A Connection Profile consists of connection information stored by the Modem
Manager software. It contains all of the necessary data to identify your modem to
your service provider in order to access your GSM or GPRS network account.
Depending on your service provider’s requirements, your modem will use a single
pre-defined connection profile or multiple pre-defined connection profiles. You
can also create your own (user-defined) connection profiles using the Add
Connection Wizard.
Using a Single Pre-Defined Connection
Profile
If your service provider requires you to use a single pre-defined connection
profile, once you have successfully installed the Modem Manager software, no
further modem configuration will be necessary. When launched, the Modem
Manager will automatically use the single pre-defined connection profile
(previously installed by your service provider) to connect to the GSM or GPRS
network.
Using Multiple Pre-Defined Connection
Profiles
If your service provider has installed a number of pre-defined connection profiles,
once you have successfully installed the Modem Manager software, you must
select the connection profile you wish to use from the Connection Selection
window. See Figure 38.
26 Using Connection Profiles
Manual Revision 1.0 P/N 90023333
To select a connection profile:
1. Launch the Modem Manager and select a connection profile (as instructed by your service
provider) from the Connection Selection window.
Figure 38 Connection Selection window
2. Click Connect to connect to the GPRS or GSM network.
Creating a User-defined Connection Profile
You can create your own (user-defined) connection profile to connect to the GPRS or GSM
network (you must obtain the connection information from you service provider). The Add
Connection Wizard will assist you in creating either a GPRS or GSM connection profile.
To create user-defined connection profile:
1. Launch the Modem Manager by double-clicking on the GPRS Modem Manager desktop icon
(If the icon is on your desktop), shown in Figure 39.

General
This equipment generates, uses, and can radiate radio frequency energy, and, if not properly
installed and used in accordance with the instructions, may cause harmful interference to radio
or television reception, or to the proper operation of PDAs and laptop computers. This can be
determined by turning the equipment on and off. You are encouraged to try to correct the
interference by one or more of the following measures:
• Reorient or relocate the receiving antenna of the television, radio or cordless telephone.
• Increase the separation between the equipment and the receiver.
• Connect the equipment to an outlet on a circuit different from that to which the receiver is
connected.
Consult the dealer or an experienced radio/television technician for additional suggestions.

Glossary
Access Point Name (APN)
The IP domain name (e.g.; novatelwireless.com) of the network device that
acts as a gateway by connecting a GPRS wireless radio network to a wired
local or wide area network.
Active Network Session
An active network session allows you to send and receive data across the
Internet using point-to-point protocol through your current network
connection.
AT Commands
AT commands are a modem-specific language type that enables PC
communications software control the modems directly. The term AT comes
from the command terminology which always begins with attention, or AT.
dBm
dBm stands for decibels below 1 milliwatt. It is a measurement of a device’s
signal output power compared against a standard input signal strength of 1
milliwatt. This number represents a ratio and is expressed as a negative
number (e.g.; -60dBm). The valid range for your Merlin for GPRS is -113 dBm
to -51 dBm. Values closer to zero indicate a better reception. The value -51
dBm indicates a better reception than -113dBm.
Default Network Connection Profile
The default network connection profile is the connection profile, chosen by
the user, that the Modem Manager will use to connect to the network. The
default network connection profile can be thought of as the active network
connection profile.
Domain Name
The name assigned to a computer or group of computers that constitute an IP
network domain. In general, a domain name is comprised of its local host
name and its top-level domain. The top-level domain can be made up of
several names, each separated by a period (.).
An example of a domain name is novaltelwireless.com.
Domain Name System (DNS)
This is a network server used on IP networks, such as the Internet, for
translating network host names and Universal Resource Locators (URL’s) into
IP addresses.
Domain Name System (DNS) Address
The IP (internet protocol) address of the Domain Name System (DNS).

Firmware
Firmware is a program or set of programs that have been set permanently into a computer
chip. These are low-level programs that directly manipulate or interact with the hardware.
Firmware is a single program or a combination of programs that have been placed on a
PROM, EPROM or EEPROM prior to the product leaving the manufacturing facility.
GPRS
GPRS stands for General Packet Radio Service. GPRS is a high-speed data transfer
technique, used on GSM networks. It does not require a continuous data stream be opened
between the data source and destination. Instead, it uses packets to move data back and
forth, making efficient use of the available radio spectrum.
GSM
GSM stands for Global System for Mobiles. It is an open, non-proprietary system with
international roaming capability providing seamless and standardized same number contact
ability in more than 170 countries. GSM satellite roaming has extended service access to
areas where terrestrial coverage is not available.
GSM uses digital technology and time division multiple access transmission methods. Voice
is digitally encoded via a unique encoder, which emulates the characteristics of human
speech. This method of transmission permits a very efficient data rate/information content
ratio.
IMEI
IMEI stands for International Mobile Station Equipment Identity.
Internet Protocol (IP)
Internet Protocol works in conjunction with Transmission Control Protocol (TCP). TCP/IP are
part of a group of protocols that provide communication across interconnected networks.
TCP/IP is the protocol used on the Internet. The TCP protocol first establishes a connection
between two systems to send and receive data, and then breaks and sequentially marks the
message into small packets. The IP protocol routes and sends the packets based on the IP
address.
IP Addresses
As with personal computers that access the Internet, modems using GPRS technology also
use Internet Protocol (IP) address, which are used to identify the node or access point for the
modem on the Internet. The service provider assigns this IP address.
The 32-bit host address is usually represented in dotted decimal notation, e.g. 128.121.4.5.
The address can be split into a network number (or network address) and a host number
unique to each host on the network and sometimes also a subnet address.
IP Network
A network of computers that use Internet Protocol allowing a user to access the Internet,
provided that the user has a modem; telephone line, cable line, or wireless data network (e.g.
GPRS); and a service provider.
Local Area Network (LAN)
A computer network that spans a relatively small area (typically up to a 1 km radius), although
most LANS are confined to a single building or group of buildings. This type of networking
allows for easy interconnection of terminals, printers, and computers within a building or
buildings.

Network Connection Profiles
A network connection profile is a group of connection settings that define a specific network
connection to the Modem Manager. This includes such settings as network ID, network
password, APN, and DNS addresses.
Packet
A short block of data transmitted across a network.
Packet Size
The size of a packet expressed in bytes.
PC Card
A PC Card is a module similar in size to a credit card and compatible with PCMCIA PC Card
standards. A PC Card can be used to add optional hardware to portable computing devices.
Some examples of such options are adding modems, network cards, disk drive adapters, and
extra memory to devices such as PDAs.
PC Card Slots
The PC Card slots are the sockets in the computing device in which the PC Card is inserted.
It is the hardware interface between the computing device and the PC Card.
Point-to-Point Protocol (PPP)
PPP is an interconnection protocol which allows a device, such as a wireless IP modem, to
connect to a network or the Internet.
Primary Domain Name System
To retrieve the translated IP addresses, the modem will try to connect to the server with the
primary DNS address. If the modem cannot connect to this address, it will try to connect using
the secondary DNS address.
Registration
To send and receive data across a given network, a GPRS modem must first register on a
GSM/GPRS network. This involves the selection of an available channel and interaction with
various systems on the GPRS network to set up a communication path.
Secondary Domain Name System
To retrieve the translated IP addresses, the modem will try to connect to the server with the
secondary DNS address in instances where it cannot connect to the primary DNS address.
Segment
Each IP network address consists of four numeric segments, which are divided by a period
("."). For example, 204.119.63.40.
Service Provider
A company that provides network connections to the Internet.
SIM
The term SIM stands for Subscriber Identity Module.
