Connections Ethernet LAN 4x 10/100Base-TX, auto sensing, switch with node/hub auto sensing
All ports can be switched into the ’Private
Mode’, whereby the ports are concealed from
one another.
Individual ports can be
switched into ’Private
Mode’, e.g. as a DMZ
port

DSLoL (DSL over LAN) LANCOM 821 ADSL/ISDN and LANCOM 1621
ADSL/ISDN can also use a vacant switch port as
a WAN access (DSLoL interface). This can be
used for a subsequent upgrade to an SDSL con-
nection, for example. The DSLoL conector is
connected either to a modem (for PPPoE access
only), or a network terminal router (with static
IP address).
