About ZyXEL AES-100
ZyXEL AES-100 is a powerful and innovative ADSL-Ethernet switch. The AES-100 aggregates the traffic from up to 16 ADSL lines to the Ethernet port and forwards it to ZyXEL's Prestige 1400 IP WAN router or a third party router/switch. The router then routes the traffic further to the Internet.
Compatible with standards-based ADSL, the AES-100 can be deployed alone or together with ZyXEL's ADSL CPE or WAN routers to form an integrated broadband access solution. By Deploying the AES-100 in a large residential building, commercial building or hotels, service providers are able to leverage the existing phone line wiring to provide broadband access to all tenants.
