Introduction 14
Model 6081RC Network Access Server Getting Started Guide 1 • Model 6081RC overview
Introduction
The Model 6081RC Network Access Router (see figure 1) is a MIPS-based processor blade for the ForeFront
Access Infrastructure System (AIS). With hardware and software features optimized for Layer-2/Layer-3 net-
working, the 6081RC enables the AIS to deliver IP as an access infrastructure element as well as support the
delivery of advanced broadband IP services and applications.
Figure 1. Model 6081RC EdgeRoute Network Access Router
When installed into the 2U, 4U, or 6U ForeFront chassis, the Model 6081RC adds IP routing and access ser-
vices to installed interfaces, such as xDSL, T1/E1, and STM ports. With the addition of data termination
packages, as well as select edge services packages (e.g. DNS), the Model 6081RC provides full-featured
ipDSLAM functionality to any ForeFront system.
The Model 6081RC preserves legacy TDM services while providing Layer-2/Layer-3 services. TDM data
communications can operate seamlessly within the same hardware, the same chassis, even over the same
wired infrastructure.
Product overview
The Model 6081RC is a frame and service edge-routing resource that provides access-to-edge, packet-based
services for IP termination; forwarding; and frame services within a ForeFront AIS chassis. Ideal for use by ser-
vice providers, the Model 6081RC provides:
•Aggregation for customer DSL/T1/E1 to framed network services, including Ethernet bridging and VLAN
v1 and v2
•IP routing and forwarding (including complete RIPV2 and OSPF)
•IP access services (including QoS class-based queuing, NAT, and firewall)
The Model 6081RC interfaces to ForeFront line cards via the TDM chassis. The 6081RC processes packets at
45k packets per second (pps). The main differences based on the processor chosen. With access to all 4,096
DS0s the 6081RC allows up to 2,048 discreet full-duplex data connections from a single card.

Network connections may come from any number of ForeFront interfaces. The 6018RC allows any resource
card within ForeFront to deliver TDM and IP/packet services on a DS0-by-DS0, connection-by-connection
basis.
The ForeFront system with the 6081RC allows:
• Any DSL or T1/E1 port to deliver IP access
•This access can be offered simultaneously with other TDM services
•This access can be on the same DSL or T1/E1 link as the same time
Leveraging ForeFront’s any-to-any architecture packet services expands the scope of services from a single
installed system. Providers can now use ForeFront for simultaneous TDM/leased-line and packet service deliv-
ery. The smart carrier today wishes to incorporate IP/L2/L3 services as an infrastructure element into their ser-
vice offering. Based on the foundation of intelligent TDM switching and integrated DACsing, the Patton
ForeFront architecture is highlighted by the following key features:
•Any DS0 level timeslot can be used for either TDM or IP Accesses. This is operator selectable and not lim-
ited by a module, external equipment, or backplane capabilities.
•Access to any DS0 is completely non-blocking. In other words, you are not limited to a specific data
path/backplane, service selection based on the capabilities of a module, or it’s location within a shelf.
•Delivery using Integrated wires through the use of the standard and integrated DACS. Now, both TDM
and IP can be offered on the same DSL, E1, or STM/VC12 ports at the same time. For example, using the
Patton 3086 IAD, you can deliver nx64kbps for TDM access and select the remaining bandwidth for
Packet access. Both services can run at the same time over the same port and terminate at the customer
premise in a single low-cost unit.
•Local network based and processing and termination. We continue legacy TDM services without disrup-
tion, but add value-added protocol internetworking to those TDM applications.
The 6081RC connects directly to all channels (4,096) on the H.110 bus and is agnostic to the line interface
method. The current set of compatible ForeFront resources which interface to the 6081RC include:
•3096RC G.SHDSL 16 port, 64-kbps–4.6 Mbps, 2-wire access
•3196RC iDSL 16 port, 64/128/144-kbps, 2-wire access
•2616RC T1/E1 DACs bulk DS0 cross-connecting
•6511RC STM-1 (63 E1s, 84 T1s per connection)
Since the 6081RC can go into any of the available slots processing and routing/switching power can be
increased by simply adding more cards to a system. The following tables indicates the number of 6081RCs that
can placed into a single chassis:
Chassis Card support Aggregate packet processing
Model 6276 (2U) Supports up to 4 6081RC 400K pps
Model 6476 (4U) Supports up to 8 6081RC 800K pps
Model 6676 (6U) Supports up to 17 6081RC 1.7M pps

The 6081RC’s applications give life to the hardware features of the 6081RC. Details of the software applica-
tions are indicated in the section 6081RC IP Access Server Functionality.
•PPP Bridging and Routing
•VLAN Ethernet Support
•OSPF/RIPv1 and v2 and static routing
•SNMPv1,2,3
•RADIUS AAA Client
•HTTP/web for management
•Apache HTTP/WEB
•NTP Network Time
•Syslog
Additionally, new applications such as L2TP, IPSEC, and MPLS will be added in releases subsequent releases.
The HTTP WEB GUI provides for easy configuration, provisioning, and management. Full SNMP control of
the device allows standardized OSS configuration and provisioning when used with an external FCAPS NMS.
Using SNMP management, the 6081RC is fully configured, managed and monitored via Patton’s ForeSight
EMS solutions. With ForeSight, a Graphical User Interface provides an intuitive, real-life representation of all
installed ForeFront equipment and enables network managers to control and monitor device functions, port
settings and receive device status information and statistics via SNMP. Features include management, a
routable configuration utility, SNMP trap manager, device autoscan, automatic configuration and device firm-
ware downloads and more. The user and NMS have full remote control for provisioning, alarms, accounting,
and security.

Note When the Fast-Ethernet PMC module (part number
PEC1/FENET/2/TX) is installed in PMC slot 2, you may redirect
one or both internal Ethernet ports B and C to the front-panel RJ-45
connectors B and C (See section “Ethernet interface configuration”
on page 40). Redirecting an Ethernet port to the front panel disables
the backplane interface for that port.
RS-232 control port
The RS-232 port provides for initial configuration of the Model 6081RC’s IP and gateway addresses. The RS-
232 port supports:
•Asynchronous data rates of 19.2 kbps, 8 data bits, no parity, 1 stop bit.
