Introduction
1.1 An Overview of TW-EA500 and EA200
TW-EA500 ADSL Router combines an “always-on” high speed Asymmetric Digital Subscriber
Line (ADSL) connection to the telephone line into a single cost-effective solution.
TW-EA500 ADSL Router is compliant with the full-rate ANSI T1.413 Issue 2 and ITU G.dmt
(G.992.1) ADSL standards, and with the splitterless ITU G.lite (G.992.2) specification. Both
Annex A (ADSL over POTS) and Annex B (ADSL over ISDN) of G.992.1 and G.992.2 are
supported. This rate-adaptive solution is designed for Customer Premise Equipment and supports
downstream data rates of up to 8 Mbps and upstream data rates of up to 1 Mbps.
TW-EA500 ADSL Router simultaneously supports Ethernet to enable the widest array of host
connectivity. The Router performs ATM Segmentation and Reassembly (SAR), industry
standards for PPP over ATM (RFC 2364), bridged/routed Ethernet over ATM (RFC 1483),
Classical IP over ATM (RFC 1577), and PPP over Ethernet (RFC 2516), resulting in a cost-
effective solution suitable for both full rate and G.lite applications. The non-reliance on host PC
software drivers make the TW-EA500 ADSL Router ideal for ubiquitous broadband connectivity
that is not limited by host OS, processor type/speed, or memory.
Networking support includes both bridge and router modes. Router Mode supports advanced
features such as Network Address Translation (NAT), Dynamic Host Configuration Protocol
(DHCP), and Routing Information Protocol (RIPv2).
All setup and provisioning is performed by a simple, easy-to-use, Web interface.
