The primary objective of this manual is to help network administrator operate AH507
bridge and router product. Strongly committed to user friendly, this manual will guide the
users step by step to turn the product up and running in the simplest way ever.
1.2 Overview
The AH507 is an ATM based G.SHDSL terminating device enabling the transport of
multi mega bits stream over one or two pair of copper wires using TC-PAM technology.
The unit complies with ETSI and ITU standard including G.991.2, allows full duplex and
operates at speed of 2.3 Mbps over 2-wire, and up to 4.6 Mbps over 4-wire loop. Based
on these standards, the AH507 is interoperable with the majority of DSLAM where
connections to the ATM core switches are made.
Each AH507 supports a wide range of protocols and features, including IP routing, pointto-point protocol (PPP), ATM, frame relay, and standard bridging protocols. Embedded
with FRF.5 and FRF.8 Frame Relay to ATM Inter-working function, the AH507 thus
offers simultaneous connection of legacy Frame Relay equipment as well as routed IP
services to high speed ATM switch.
The port-based Virtual Server or host-based DMZ features allow local servers to be
exposed to the Internet for providing services such as File Transfer, Mailing, HTTP or
Telnet. In-built ACL (Access Control List) feature enables the unit to examine the
network traffic's Source IP address, Destination IP address, and IP protocol type to
decide if the IP traffic is allowed to pass through it.
Unlike simple Internet sharing device, the AH507 is a true firewall router, using stateful
packet inspection to defend against Denial of Service (DoS) attacks.
The VPN Pass Through feature supports the pass through of IPSec, L2TP or PPTP
tunnel for a secured transmission between two VPN endpoints
Remote management function allows user to be able accessing the AH507 via Web,
Telnet for configuration, or TFTP for firmware upgraded. It offers the embedded DHCP
server, which helps system administration manage the IP address network in the easiest
way ever.
