About the Hotwire 8300 Endpoint
Introduction
The Hotwire®8300 Endpoint is a feature-rich, intelligent integrated access device
(IAD) that manages voice and data applications in an ATM network. The
8300 Endpoint 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 8300 Endpoint is a service-aware IAD with the following hardware:
 SHDSL network interface
 Constant Bit Rate (CBR) port configurable as T1 or E1
 Serial port software-configurable for V.35, V.36, X.21, RS-232, RS-449, or
EIA-530
 10/100Base-T Ethernet port
 Asynchronous Supervisory port
 Five tri-color status LEDs
 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 customer premises 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 8300 Endpoint’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
AT M (P P Po A ) 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
RIP (Routing Information Protocol) 1 and RIP 2, or OSPF (Open Shortest Path
First), Dynamic Host Communications Protocol
( DHCP), and Network Address
Translation (NAT).

1. About the Hotwire 8300 Endpoint
1-2 April 2003 8300-A2-GB20-00
RIP 1 and RIP 2 allow routers to exchange routing information. The 8300 Endpoint
then uses this information exchange to build routing tables for IP Packet routes.
After building the routing tables, the unit periodically broadcasts the contents to
neighboring routers so your network can choose the most efficient routes
available.
OSPF uses link-state routing algorithms to calculate routes based on the number
of routers, transmission speeds, delays, and route costs. Using the OSPF
protocol, the 8300 Endpoint works with other routers in your telecommunications
fabric to dynamically change routes on the fly to make use of the most efficient and
cost-effective transit across your network.
Bridging separate LANs together is another option for the IP traffic. Using the IEEE
Standard 802.1D Transparent Bridging specification, the 8300 Endpoint can
simplify your network architecture by allowing you to bridge separate LANs across
a WAN so they operate as a single LAN.
Because IP Gateway enables the 8300 Endpoint to route IP traffic either statically
or dynamically or to bridge IP traffic across your LAN/WAN architecture, your need
for costly routers is substantially reduced. This one-stop solution can help you
meet the requirements of your many different applications.
DHCP uses a server-client architecture to assign IP Addresses to PCs and
workstations on the LAN. The DHCP server dynamically assigns these IP
Addresses, which can be either temporary or permanent, to each PC or
workstation (DHCP client). These IP Addresses are housed on the DHCP server.
The flexibility to reassign IP Addresses saves the end user money by eliminating
the need for a single IP Address for each piece of equipment on the LAN.
NAT enables an enterprise to set up two sets of IP Addresses: one set for internal
network use (or LAN traffic) and one set for external use (or Internet traffic). This
can provide a layer of security for a company by eliminating outside access to
internal IP Addresses from the Internet.
The 8300 Endpoint gives service providers and enterprise customers the
capability to monitor end-to-end network performance (with support of up to 16
virtual channels); isolate performance problems to the LAN, local loop, or ATM
network; determine appropriate bandwidth needs; and monitor network trends to
aid in future capacity planning.
All of the 8300 Endpoint’s installation, performance configuration, traffic
monitoring, alarm reporting, and diagnostic capabilities can be configured through

Features of the 8300 Endpoint
Performance
Historically, WAN access devices have tended to perform well as single-function
devices such as CSU/DSUs, but have not been optimized to address higher-level
traffic issues such as service levels and integration. The 8300 Endpoint’s
architecture and web-based user interface work together to address all access
issues such as services and applications, rather than as circuits and protocols, for
exceptional WAN management performance.
The 8300 Endpoint also allows firmware to be upgraded via the web from a
standard browser, with password control if desired.
SNMP Management
With integrated SNMP in-band management, enterprise managers can now
manage 8300 Endpoints and their integral CSU/DSUs as a single unit. With only
one LAN segment in the network, the 8300 Endpoint can be managed by SNMP.
By downloading all configuration parameters from the central site, no interaction is
required at remote sites to establish connectivity. The unit allows any port to be
configured for any of its available service technologies through simple software
configuration. Network managers can now fine tune the enterprise network for the
lowest cost and highest performance.
Intelligent WAN Access Architecture
The 8300 Endpoint’s WAN access architecture is built around a PowerPC™
processor with 50 MIPS of processing power and 16 Mbytes of onboard memory,
and works with non-proprietary network management solutions via SNMP. An
embedded web server supplies a simple-to-use interface for configuration and
statistics collection, with a service table for mapping services to ports and a user
table for monitoring and controlling traffic.
Overview and Advantages
The 8300 Endpoint is an innovative, highly intelligent, software-based WAN
access device optimized for ATM over G.shdsl access. This unit provides network
managers with all the tools necessary to monitor and troubleshoot voice, data, and

To access the Web Server interface, type the unit’s IP address in the browser’s
Address (or Location) field and press the Enter key.
Layout of Interface Screens
When you first access the Web Server interface, your browser will display a
screen that is divided into three frames. The upper frame forms a border across
the top of the screen; it identifies the unit in service and displays the hardware and
software revision and serial numbers under which the unit is operating. The far
right corner of the upper frame displays whether or not a Save and Restart is
necessary when parameters are changed on the currently displayed screen.
The area beneath the upper frame is divided into two side-by-side frames. The
frame on the left side of this area depicts a hierarchical tree structure used to
navigate through the various interface screens. Each branch on the tree guides
you to more specific upper-level information about the unit and its configuration.
Note that the Interfaces, Applications, and Utilities branches do not link to a page;
these branches simply provide structure for navigation. The frame on the right side
of the screen displays the actual configuration screen. The screen images
throughout this chapter show only the configuration portion of the screen, except
in the case of the Unit screen, which shows the left and right frames. The Unit
screen represents the top of the navigation tree.
