Patton electronics 2784 NAU Manual de usuario
he Patton 2784 Network Access Unit is a multiservice,
integrated access platform that enables service providers to
integrate dial-in modem users, Internet, Extranets, Corporate
Intranets or IP LANs–using Ethernet, Frame Relay, or PPP–over
a single network backbone connection.
Network connectivity has developed into an integral part of today’s
business infrastructure. The number of connected users directly
translates into an increased demand for WAN access. Private enterprise
networks, incumbent local exchange carriers, and competitive local
exchange carriers (CLEC's) have all found that, in order to compete
effectively, they must offer products and services which form an
integrated solution.
By providing an integrated business solution, carriers now have the
opportunity to leverage technology to further their own business
objectives. By eliminating multiple pieces of equipment, application
performance is enhanced. Through simplified configuration and network
management, maintenance and support costs are dramatically reduced.

OVERVIEW • MANAGEMENT
Patton 2784 Network Access Unit
Product Overview
The 2784 NAU enables the small/medium-size enterprise to
take advantage of multiservice networking using a single
multifunction platform for service concentration. The
enterprise customer can now employ a single carrier facility
(T1 or E1) for voice, data, Internet, LAN and remote access
applications.
Frame Relay virtual circuits allow interoffice
communications without using additional leased lines,
dramatically reducing both equipment and facilities’ costs.
Frame Relay’s ability to combine multiple streams of
“bursty” data over a single physical interface provides the
advantage of high bandwidth and wide area connectivity.
The Drop-and-Insert port serves an attached PABX for
local voice calls to the public switched telephone network.
Through user configurable timeslot selection, the 2784 NAU
can process Voice and Modem calls by routing a call to
either the PABX or to an internal modem for dial-in remote
access (RAS).
By answering and terminating both analog (V.90,
K56Flex™, V.34+) and digital (ISDN) calls, the 2784
functions as a Remote Access server. Each call is processed
by a single DSP functioning as a digital modem. PPP/SLIP
users easily become an attached node on the network. Built-
in filtering offers security over users’ activity on the network.
IP Routing permits access of local area network traffic
either to remote offices or to the Internet through the built-in
routing engine. IP datagrams, routed by the CPU, are then
forwarded to a FR/PPP WAN port or a 10Mbps Ethernet
LAN for delivery.
The 2784 NAU provides for extensive
connection management and operator control
from a variety of local and remote interfaces.
Each 64kbps DS0 can be configured to support
six unique services–all using an easy-to-learn
GUI.
Management interfaces are presented through a
built-in SNMP agent, an embedded HTTP Web
server, or via a standard TELNET session.
Access, with security through multi-permission
passwords, is accomplished through the RS-232
console port, Ethernet port, Frame Relay port,
or through any dial-in port.
The built-in HTTP server allows each 2784
management screen to appear as an intuitive
Web page to the user. Operators can configure,
control, monitor or receive status on any 2784
parameter–from any PC.
SNMP/HTTP Connection
Management
The 2784 NAU provides integrated voice support by
presenting up to 24 voice/fax calls onto the T1 DSX-1 Drop-
and-Insert port. The user may select the number of channels
(1-24 voice/fax calls) to be "dropped" onto the PABX port by
customizing the DS0 channel selection configuration through
the SNMP/HTTP NMS (see screen snapshot, opposite).
DS0s can also be identified as dial-in modem ports. With this
facility, the 2784 will intercept and answer V.90, K56Flex
™
,
V.34+ and ISDN BRI users via built-in DSP modems.
This allows the 2784 to minimize costs and maximize
facilities by answering remote access calls within the 2784,
while switching calls to the PABX to handle corporate
voice–all at the same time. Now users can call the corporate
voice and data networks, using different telephone numbers
on the same T1.
The 2784 NAU offers a flexible and cost-effective network
access solution using Frame Relay over a multi-service
T1/E1 connection. Designed to be simple and efficient,
Frame Relay is a data networking technology for connecting
remote offices over the Wide Area. While eliminating the
need for individual and expensive leased lines, Frame Relay
provides distance insensitive connections to remote
networks. Connectivity is established through logical end-to-
end connections [Permanent Virtual Circuits (PVCs)]
between the 2784 and the remote office.
Frame Relay provides multiple PVCs over a single physical
circuit, which allows the 2784 to forward data over those
connections to its intended destinations. Using RFC-1490
multiprotocol encapsulation and the 2784's sub-interface
architecture, each virtual circuit is multiplexed over a single
physical interface. The 2784 NAU scales to support
additional connections without adding to capital equipment
costs.
By combining the capabilities of a CSU/DSU, FRAD and
router, the 2784 provides scalability without the additional
costs of multiple pieces of equipment.
APPLICATIONS
Patton 2784 NAU Applications
Frame Relay
Corporate Voice Integration
Flat rate pricing from service providers results in significant
cost savings when comparing leased-line services with public
facilities from carriers. As a cost-effective alternative to direct
dial-in connections or leased lines, Virtual Private Networks
(VPNs) create a new telecommunications capability by
providing secure remote access across the public Internet or
Frame Relay network.
By permitting the enterprise to use a public data network,
VPNs take advantage of the Internet's global presence. Using
the Patton 2784 NAU, mobile and SOHO users can create
secure intranet access using industry standard Layer 2
Tunneling (L2TP) and IP Security (IPSec) VPN technology.
VPN's support secure remote access to the home network
LAN. A secure path, or “tunnel”, is set-up between the 2784
and the end user. Once the session is established, applications
function as though a direct connection to the local LAN exists.
Tunneling encapsulates private intranet traffic into the Internet,
while security enhancements control user authentication,
authorization and encryption to assure confidentiality of all
private information.
