Interfaces
WAN: ADSL
ADSL over ISDN compliant with ITU G.992.1 Annex B (compatible to Deutsche Telekom U- R2 connections) or ADSL over POTS
compliant with ITU G.992.1 Annex A
WAN: ADSL2+
ADSL2+ over ISDN compliant with ITU G.992.3, ITU G.992.5 Annex B (ADSL2+) or ADSL2+ over POTS compliant with ITU G.992.3
and ITU G.992.5 Annex A (ADSL2+)
Ethernet ports
4 individual 10/100- Mbps Fast Ethernet ports; up to 3 ports can be switched as additional WAN ports with load balancing.
thernet ports can be electrically disabled within LCOS configuration
- freely configurable
Each Ethernet port can be freely configured (LAN, DMZ, WAN, monitor port, off). LAN ports can be operated as a switch or
separately. Additionally, external DSL modems or termination routers can be operated as a WAN port with load balancing and
policy- based routing. DMZ ports can be operated with their own IP address range without NAT
USB 2.0 host port
USB 2.0 full- speed host port for connecting USB printers (USB print server) or serial devices (COM port server); bi- directional
data exchange is possible (max. 12 Mbps)
ISDN
ISDN BRI port (S0 bus)
Serial interface
Serial configuration interface / COM port (8 pin Mini- DIN): 9,600 - 115,000 baud, suitable for optional connection of analog/
GPRS modems
Management
LANconfig
Configuration program for Microsoft Windows, incl. convenient Setup Wizards. Optional group configuration, simultaneous
remote configuration and management of multiple devices over ISDN dial- in or IP connection (HTTPS, HTTP, TFTP). Configuration
program properties per project or user. Automatic storage of the current configuration before firmware updates. Exchange of
configuration files between similar devices, e.g. for migrating existing configurations to new LANCOM products. Detection and
display of the LANCOM managed switches
LANmonitor
Monitoring application for Microsoft Windows for (remote) surveillance and logging of the status of LANCOM devices and
connections, incl. PING diagnosis and TRACE with filters and save to file. Search function within TRACE tasks. Wizards for
standard diagnostics. Export of diagnostic files for support purposes (including bootlog, sysinfo and device configuration
without passwords). Graphic display of key values (marked with an icon in LANmonitor view) over time as well as table for
minimum, maximum and average in a separate window, e. g. for Rx, Tx, CPU load, free memory. Monitoring of the LANCOM
managed switches
Firwall GUI
Graphical user interface for configuring the object- oriented firewall in LANconfig: Tabular presentation with symbols for rapid
understanding of objects, choice of symbols for objects, objects for actions/Quality of Service/remote sites/services, default
objects for common scenarios, individual object definition (e.g. for user groups)
WEBconfig
Integrated web server for the configuration of LANCOM devices via Internet browsers with HTTPS or HTTP. Similar to LANconfig
with a system overview, syslog and events display, symbols in the menu tree, quick access with side tabs. WEBconfig also
features Wizards for basic configuration, security, Internet access, LAN- LAN coupling. Online help for parameters in LCOS menu
tree
Device Syslog
Syslog buffer in the RAM (size depending on device memory) to store events for diagnosis. Default set of rules for the event
protocol in Syslog. The rules can be modified by the administrator. Display and saving of internal Syslog buffer (events) from
LANCOM devices with LANmonitor, display only with WEBconfig
Access rights
Individual access and function rights for up to 16 administrators
User administration
RADIUS user administration for dial- in access (PPP/PPTP and ISDN CLIP). Support for RADSEC (Secure RADIUS) for secure
communication with RADIUS servers.
Remote maintenance
Remote configuration with Telnet/SSL, SSH (with password or public key), browser (HTTP/HTTPS), TFTP or SNMP, firmware upload
via HTTP/HTTPS or TFTP
Support of protocol for authentication, authorization and accounting (AAA) with reliable connections and encrypted
payload. Authentication and authorization are separated completely. LANCOM access rights are converted to levels.
With access can be granted per parameter, path, command or functionality for LANconfig, WEBconfig or Telnet/SSH.
Each access and all changes of configuration are logged. Access verification and logging of SNMP Get and Set requests.
WEBconfig supports the access rights of and choice of server at login. LANconfig provides a device login
with the request conveyed by the addressed device. Authorization to execute scripts and each command within them
by checking the server’s database. CRON, action- table and script processing can be diverted to avoid to
relieve servers. Redundancy by setting several alternative servers. Configurable option to fall back to local
user accounts in case of connection drops to the servers. Compatibility mode to support several free
implementations
Remote maintenance of 3rd party
devices
A remote configuration for devices behind der LANCOM can be accomplished (after authentication) via tunneling of arbitrary
TCP- based protocols, e.g. for HTTP(S) remote maintenance of VoIP phones or printers of the LAN
ISDN remote maintenance
Remote maintenance over ISDN dial- in with calling- number check
TFTP & HTTP(S) client
For downloading firmware and configuration files from a TFTP, HTTP or HTTPS server with variable file names (wildcards for
name, MAC/IP address, serial number), e.g. for roll- out management. Commands for live Telnet session, scripts or CRON jobs
