| ALX-2002 |
| Aliwei ALX-2002 is the innovation
of Aliwei VoIP solution. As the VoIP/FoIP media access gateway,
the ALX-2002 works at the user access layer of VoIP system.
It completes functions like the conversion between the analog
voice signal and the IP packet, and data transmission through
the packet switching network. When networking with the softswitch
through the standard Media Gateway Control Protocol (MGCP),
it can implement the call connection between the calling
and the called parties under the control of the softswitch.
ALX-2002 can provide the hybrid access of VoIP service for
POTS users or data users. On the standard category 5 cable,
the combo port of data and voice is realized for the unified
access of broadband users and voice users. |
| ALX-2002 provide
scalability, reliability and stability for voice over IP
(VoIP) or fax over IP (FoIP) solutions including IP-routing
services for enterprise, government and other public offices
as well as VoIP carriers and telecom carriers |
