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
Cable tester
WAN/ADSL
'Annex A' devices : ADSL over POTS as per ITU 
G.992.1 Annex A, ANSI T1.413, ITU G.992.2 
(G.Lite), G.994.1 (G.hs);
'Annex B' devices : ADSL over ISDN as per ITU 
G.992.1 Annex B, as well as proprietary ADSL 
over ISDN (Texas Instruments, ADI, Alcatel), 
ETSI TS 101 388
10/100Base-TX, auto 
sensing
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).
