Introduction
Verilink’s WANsuite 6450 is a feature-rich, intelligent integrated access device
(IAD) that manages voice and data applications in an ATM network. The
WANsuite 6450 terminates a standards-based Symmetric High-Bit Rate
Digital Subscriber Line (SHDSL) that originates from a Digital Subscriber
Line Access Multiplexer (DSLAM) and provides interfaces for the end user’s
communications equipment.
The WANsuite 6450 is ServiceAware™ IAD with the following hardware: an
SHDSL network interface; a Constant Bit Rate (CBR) port configurable as T1
or E1; a Serial port software-configurable for V.35, V.36, X.21, RS-232, RS-
449, or EIA-530; a 10/100Base-T Ethernet port; an asynchronous Supervisory
port; five tri-color status LEDs; and front panel reset and factory
configuration buttons.
The Circuit Emulation Service (CES) support provides for the encapsulation
of TDM traffic from end-user equipment into ATM cells for transport across
the WAN to the DSLAM and on to the ATM network. This allows for the
continued use of existing TDM equipment at the premise while the ATM
network continues to grow and move further out to the edge. This unit
supports CES over the CBR port and the Serial port.
A router or bridge using PPP/HDLC protocols connects to the WANsuite
6450’s Serial port. The unit encapsulates the PPP data into ATM cells using
Internet Engineering Task Force (IETF) RFC 1483. Any router/bridge
supporting PPP over ATM (PPPoA) RFC 1483 encapsulation can be used at
the other end of this ATM connection.
The IP Gateway feature enables IP packet routing throughout a LAN/WAN
network architecture using static routing configuration or dynamic routing
protocols (Routing Information Protocol
−
RIP 1 and RIP 2, or Open Shortest
Path First
−
OSPF), Dynamic Host Communications Protocol
−
DHCP, and
Network Address Translation
−
NAT.
RIP 1 and RIP 2 allow routers to exchange routing information. The
WANsuite 6450 then uses this information exchange to build routing tables
