A splitter is also used at the subscriber end to permit ADSL modems/routers
and conventional telephone equipment to be used at the same time.

In some models (like in the picture above) the ADSL modem is integrated
directly in the router (e.g. LANCOM 1521 Wireless ADSL and LANCOM 1821
Wireless ADSL). Other models like LANCOM 1511 Wireless DSL or LANCOM
1811 Wireless DSL are connected to the splitter using a separate ADSL
modem.

The models LANCOM 1511 Wireless DSL and LANCOM 1811 Wireless
DSL can also utilize other broadband connections (e.g. cable modem)
that offer a 10/100Base-Tx-Ethernet connector over PPPoE, PPTP or
plain Ethernet (with or without DHCP).
