Preface
Thank you for your confidence in us!
With its integrated UMTS/HSxPA modem, the ADSL2+ router LANCOM 1751
UMTS sets standards in flexibility and redundancy. Should a standard DSL
connection fail at a site, branch office or subsidiary, automatic compensation
is provided by a broadband UMTS/HSxPA or EDGE backup connection. Alter-
natively the ISDN interface can be used as a further backup line or for remote
access. Along with this unique level of high availability, the LANCOM 1751
UMTS is equipped as standard with 5 VPN channels (optionally 25), an inte-
grated ADSL2+ modem and four separately configurable switch ports, so offe-
ring a huge variety of professional applications.
The SIM-card holder is easily accessible via the back cover and, by connecting
an external UMTS antenna, indoor reception can be greatly improved. A real
highlight: Anti-theft by ISDN self-callback and location determination by GPS!

1Introduction
Networked cooperation between several offices or even between continents
has become an everyday part of modern business. The paths of communica-
tion between headquarters, subsidiaries and field workers increasingly rely
upon public infrastructures. VPN has become established as the de facto stan-
dard for cost-effective and secure enterprise communications over the Inter-
net.
However, many of important elements in these network structures remain sus-
ceptible to failure which could have severe consequences for business opera-
tions:
The Internet-access cable between the site and the provider could fail;
after damage from construction work, for example.
Provider's network  may be disturbed or even fail.
LANCOM UMTS Routers of the type LANCOM 1751 UMTS are equipped with
a UMTS modem and an ISDN interface to offer two integrated options for
establishing alternative connections. The LCOS operating system provides a
range of security and backup functions to protect your multi-site network
from disturbances of this type.
1.1 Various backup strategies
1.1.1 Backup via mobile-telephony lines
Backup solutions that rely on ISDN or analog telephone lines are the most
common method used today to ensure high availability of data lines such as
those between branch offices and computer centers in large company net-

works. The standard Internet connection is typically provided via an inexpen-
sive DSL connection and a backup line in the form of an ISDN/analog line
takes up the data traffic if the normal line should be disturbed.
As an alternative to this ISDN/analog backup scenario, mobile telephony con-
nections can also be used to ensure the availability of data connections. If an
Internet connection is operated via a LANCOM 1751 UMTS, then any interrup-
tion to the ADSL line can be immediately substituted by the mobile-telephony
line. The LANCOM 1751 UMTS supports all current mobile technologies:
GPRS, EDGE, UMTS and HSxPA.
Advantages of mobile-telephony backup over ISDN/analog:
Faster than ISDN/analog: Data throughput is far higher with UMTS/HSxPA.

The various mobile telephony technologies in overview:
GPRS: General Packet Radio Service, technology for packet-orientated data transfer in GSM
networks. Achieves in practice data-transfer speeds of up to 56 kbps.
EDGE: Enhanced Data Rates for GSM Evolution is technology that increases data rates over
GPRS by using an additional method of modulation. EDGE acheives theoretical data rates
of up to 384 kbps downstream and ca. 110 kbps upstream. EDGE is widely available in
many countries and offers an interesting alternative to UMTS.
UMTS: The Universal Mobile Telecommunications System is also known as the third-gene-
ration mobile-telecommunications standard (3G). The first version of UMTS reaches down-
load rates of 384 kbps.
HSxPA: High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access
(HSUPA) are protocol additions to UMTS. Various versions of HSDPA achieve download rates
of up to 14.6 Mbps, HSUPA reaches upload rates of up to 5.8 Mbps.
Actual available bandwidths depend on the version supported by the network operator and on
the UMTS modem in use.
