1 Getting started
Please follow the instructions of the Quick-Installation Guide.
As long as the device has not been configured finally…
▪The “SDSL-Link” LED flashes green, because no SDSL-access has been
configured yet (run Setup-Wizard “Set up Internet access…”)
▪The “Power” LED flashes red/green, because no password has been assigned
yet (run Setup-Wizard “Check security settings…”)
The device has been connected and configured correctly and is ready to use:
▪“Power” green
▪“SDSL-Link” green
▪“LAN-Link” and/or “USB-Link” green
2 Troubleshooting
2.1 The SDSL-Link does not work …
The SDSL Link is fine when the LED „SDSL-Link“ is GREEN permanently.
▪Please check the WAN wiring first: Ensure, that the „SDSL“ jack on the rear
panel is connected to the „phone line“, that was installed for your SDSL
access
▪Ensure that the „Set up Internet access...“ Installation-Wizard of the LANconfig
program (on CD-ROM) has been run with your appropriate provider and your
access product.
▪Note: Depending on the SDSL-variant in use, the training phase to establish
the SDSL can take a while: G.shdsl should connect within a few seconds,
whereas SDSL (fixed rate) takes up to 4 minutes. SDSL with Autobauding can
take up to 60 minutes worst case. During this phase the „SDSL-Link“ LED is
flashing green (slowly). When entering further connection phases, the flashing
is getting faster.
▪The SDSL Link is established, when the SDSL-Link LED is permanently
green.
Please contact your SDSL-Provider in case all of the above has been checked, but
the SDSL-Link cannot be established.

User manual LANCOM 1630 SDSL

2.2 The LAN-Link does not work...
Ethernet-LAN: The „LAN-Link“ LED is not GREEN permanently.
▪Toggle the Node/Hub Switch (symbol „|| / X“) on the rear panel of the device.
This crossover switch enables to connect either an Ethernet Hub / Switch, or a
PC network interface card directly, i.e. without the needing special crossover
cables.
USB: The „USB-Link“ LED is not GREEN permanently
▪Ensure that the USB interface has not been disabled in your PC’s BIOS.
2.3 The Internet access does not work
SDSL and LAN link are both OK, but a connection to the Internet cannot be
established.
Check with the PING command (command line interface), whether a known Internet
address responds, e.g.
▪PING 141.1.1.1
▪PING www.elsa.com
In case the PING is not successful (‘no reply from xxx), one could check several
internal moduls with the TRACE command for correct operation, e.g.
▪PPP
▪ATM
▪IP
▪DNS
For example, if you’re using the PPP protocol to connect to your Internet service
provider, a failed authentification due to an invalid username or password could
be recognized with an PPP trace (enter TRACE + PPP).
2.4 The Router is not accessible from the LAN...
The Router is not configured yet (ex factory, or after RESET)
▪The ELSA LANconfig (on CD-ROM) will find the Router automatically (power
on the device when it is connected to a LAN). This requires that the TCP/IP
protocol stack is installed on your computer, and that the protocol is bound the
network interface card is use.
▪The Router uses to the IP-address „a.b.c.254“ automatically, whereby „a.b.c“
is given by your local network settings (e.g. 192.168.1.254 or 10.1.1.254)
▪This requires that the address “a.b.c.254” is part of your local subnet (for
example, local net mask is “255.255.255.0”)
▪In case that the address “a.b.c.254” is already used by another device of your
local network, please disconnect or power down that device while configuring
the LANCOM 1630 SDSL the first time.

User manual LANCOM 1630 SDSL
Copyright ELSA AG, 2002 Page: 6/33
The Router has been configured in a way that it cannot be reached from the LAN
anymore
▪The Router can be reset be pressing the RESET switch on the rear panel for 5
seconds. The Router is reset to the factory default settings then.
Alternatively:
▪The Router can be configured via the serial connection („Config/COM“ on the
rear panel, 38400 baud, 8N1).
▪The Router’s IP-address can be set within the entry “BRIDGE” of the
„Communication/Connections/Router/Router Interfaces“ table.
2.5 Questions regarding the Router’s configuration...

▪Each interface can be connected the router
▪The Plain Ethernet interface can be attached to the Bridge as well
▪Interfaces connected to the router have an IP address assigned
▪Bridge and router can be enabled separately
▪The bridge can be attached to the router
▪Interfaces are identified by an arbitrary name: For example, the Internet
Access Wizard uses “ __WIZARD__”
Examples:
(1) PPPoA Router with simultaneous USB+Ethernet LAN
▪“Router” connected to “PPP” Interface
▪“Bridge” connected to “Router”
▪“USB” and “Ethernet” connected to “Bridge”
(2) IPoA Router with simultaneous USB+Ethernet LAN
▪“Router” connected to “Plain IP” Interface
▪“Bridge” connected to “Router”
▪“USB” and “Ethernet” connected to “Bridge”
(3) Ethernet Bridge
▪“Bridge” connected to “Plain Ethernet” interface
▪“Ethernet” connected to “Bridge”
▪Optional: “Router” connected with “Bridge” enables an IP address assignment
in order to support easy management and monitoring with ELSA LANtools

5 Operations and Management
5.1 Basic access methods
Note: The device responds to all IP addresses a.b.c.254 and broadcasts if not
configured yet, whereby “a.b.c” is given by your local network’s settings. The device
can be found automatically with ELSA LANconfig when powered up connected to a
LAN. Please ensure that the address “a.b.c.254” is part of the local subnet (e.g. net
mask “255.255.255.0”), and that the address is not initially used otherwise.
ELSA LANconfig (Windows GUI program):
▪Over an IP network (TFTP)
▪Over a serial connection (38400 baud, 8N1)
ELSA recommends using the LANconfig configuration tool. Other configuration
access methods do not expose the full LANconfig feature set (e.g. Setup Wizards).
Web based:
▪Any standard Internet Browser
Command line interface
▪Over a Telnet session
▪Over a TFTP session
