Model 6081RC Network Access Server User Manual
1 • Model 6081RC overview
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:
