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.
Dial-In Modems
1U-high platform with DSP architecture
for analog and digital modems
SNMP/ HTTP Management
Use SNMP or HTTP to completely configure, control,
and manage all subsystems
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.

APPLICATIONS
Patton 2784 NAU Applications
Frame Relay
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
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
networks. Connectivity is established through logical end-to- costs.
end connections [Permanent Virtual Circuits (PVCs)]
between the 2784 and the remote office.
By combining the capabilities of a CSU/DSU, FRAD and
router, the 2784 provides scalability without the additional
costs of multiple pieces of equipment.
Corporate Voice Integration
The 2784 NAU provides integrated voice support by
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.
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.

Virtual Private Networking
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.
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,
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
while security enhancements control user authentication,
authorization and encryption to assure confidentiality of all
private information.
