 Downwards compatible to ADSL2+ over ISDN compliant with ITU G.992.5 Annex B, ADSL2 over ISDN compliant with ITU G.992.3 
Annex B, ADSL over ISDN compliant with ITU G.992.1 Annex B. Supports one virtual ATM circuit (VPI, VCI pair) at a time

Ethernet ports

4 individual 10/100-Mbps Fast Ethernet ports; two can be switched as additional WAN ports. Ethernet 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 hi-speed host port for connecting USB printers (USB print server), serial devices (COM port server), USB data storage 

(FAT file system) or supported 3G USB modems; bi-directional data exchange is possible (max. 480 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. Supports internal COM port server and allows for transparent asynchronous transmission of serial data via TCP

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). A tree view 

of the setting pages like in WEBconfig provides quick access to all settings in the configuration window. Password fields which 

optionally display the password in plain text and can generate complex passwords. 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. Dynamic filter for pattern search that reduces the view to devices with matching properties. Extensive application help 

for LANconfig and parameter help for device configuration

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

Alternative boot configuration

During rollout devices can be preset with project- or customer-specific settings. Up to two boot- and reset-persistent memory 

spaces can store customized configurations for customer-specific standard settings (memory space '1') or as a rollout 

configuration (memory space '2'). A short reset (more than 5 seconds) loads the customer-specific standard settings from 

memory space 1 (if programmed; otherwise LANCOM factory settings). A long reset (more than 15 seconds) loads the rollout 

configuration from memory space 2 (if programmed; otherwise LANCOM factory settings). A further option is the storage of a 

persistent standard certificate for the authentication of connections during rollouts

Automatic update from USB

Automtatic upload of appropriate firmware and configuration files on insertion of USB memory (FAT filesystem) into USB 

interfaces of LANCOM routers with factory settings. The function can be activated to be used during operation of configured 

devices. The router checks the files’ dates and versions against the current firmware before upload

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. Alternative access control on a per parameter basis with 

TACACS+

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
