Dynamic routing with RIPv2. Learning and propagating routes; separate settings for LAN and WAN. Extended RIPv2 including HopCount, Poisoned
Reverse, Triggered Update for LAN (acc. to RFC 2453) and WAN (acc. to RFC 2091) as well as filter options for propagation of routes. Definition
of RIP sources with wildcards

Dynamic routing

VLAN ID definable per interface and routing context (4,094 IDs) IEEE 802.1Q

VLAN

Packets sent in response to LCOS service requests (e.g. for Telnet, SSH, SNTP, SMTP, HTTP(S), SNMP, etc.) via Ethernet can be routed directly to the
requesting station (default) or to a target determined by ARP lookup

ARP lookup

COM-port server for DIN and USB interfaces. For multiple serial devices connected to it, the server also manages its own virtual COM ports via
Telnet (RFC 2217) for remote maintenance (works with popular virtual COM-port drivers compliant with RFC 2217). Switchable newline conversion
and alternative binary mode. TCP keepalive according to RFC 1122 with configurable keepalive interval, retransmission timeout and retries

COM port forwarding

Host port for connecting USB printers via RAW-IP and LPD; bi-directional data exchange is possible

Print server (USB 2.0)

ARP, proxy ARP, BOOTP, LANCAPI, DHCP, DNS, HTTP, HTTPS, IP, ICMP, NTP/SNTP, NetBIOS, PPPoE (server), RADIUS, RIP-1, RIP-2, RTP, SIP, SNMP,
TCP, TFTP, UDP, VRRP

IP

PPPoE, PPPoA, IPoA, Multi-PPPoE, ML-PPP, PPTP (PAC or PNS) and IPoE (with or without DHCP), RIP-1, RIP-2, VLAN

ADSL, Ethernet

1TR6, DSS1 (Euro-ISDN), PPP, X75, HDLC, ML-PPP, V.110/GSM/HSCSD

ISDN

ADSL1, ADSL2 or ADSL2+ with internal ADSL2+ modem

xDSL

ADSL1, ADSL2 or ADSL2+ with external ADSL2+ modem

xDSL (ext. modem)

UMTS/HSDPA with external module at the USB interface

UMTS/HSDPA* (ext. module)

ISDN data or voice usage via internal ISDN interface

ISDN

Analog or GPRS operation via serial interface

Analog/GPRS (ext. modem)

A UMTS USB modem is not supplied. Supported UMTS USB modems at www.lancom.eu/umts-support

*) Note:

1

Compliant to: ADSL2+ as per ITU G.992.5 Annex A/Annex B/Annex J/Annex M, ADSL2 as per ITU G.992.3 Annex A/Annex B/Annex J/Annex M,
ADSL as per ITU.G.992.1 Annex A/Annex B

1

Supports one virtual ATM circuit (VPI, VCI pair) at a time

WAN: ADSL2+

10/100/1000 Mbps Gigabit Ethernet

WAN: Ethernet

4 individual 10/100/1000 Mbps Ethernet ports; up to 1 ports can be switched as additional WAN ports with load balancing. Ethernet ports can be
electrically disabled within LCOS configuration. The ports support energy saving according to IEEE 802.3az

Ethernet ports

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

Port configuration

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*

USB 2.0 host port

ISDN BRI port (S0 bus)

ISDN

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

Serial interface

A UMTS USB modem is not supplied. Supported UMTS USB modems at www.lancom.eu/umts-support
