ADSL WICs
The DSL wide area network (WAN) interface cards (WICs) support one DSL line between a single
customer premises equipment (CPE) subscriber and a central office.
Asymmetric digital subscriber line (ADSL) WICs are available in three variations:
•
ADSL over POTS (WIC-1ADSL)
•
ADSL over POTS with Dying Gasp support (WIC-1ADSL-DG)
•
ADSL over ISDN with Dying Gasp support (WIC-1ADSL-I-DG)
The ADSL over POTS interface card is commonly used to provide ADSL services over ordinary
telephone lines. The ADSL-over-ISDN interface card is used to provide ADSL services in those areas
of the world that have extensive ISDN backbones already in place.
