Alcatel 7652 and 7622
PowerRail Distribution Routers
The Alcatel 7652 and 7622 PowerRail Distribution Routers (PDRs), formerly the
PowerRail 5200 and 2200, are designed to meet the demands of high performance,
high availability networks within MANs, ISPs, CLECs and other service providers.
They feature extensive routing capabilities and flexible connectivity options.
Their powerful parallel access shared memory architecture and policy-based
management simplify network design and administration, reducing the cost of
ownership. Superior forwarding rates, scalability, and mission critical
resiliency features make the Alcatel 7652 and 7622 PDRs ideal solutions for
scaling the performance of your network.
Alcatel 7652 PDR
The Alcatel 7652 PDR provides 52 Gb/s of non-blocking bandwidth. A fully
loaded fourteen-slot chassis supports high performance switching at Layers 2, 3,
4 and 7, allowing port densities up to 240 auto-sensing 10Base-T/100Base-TX, 240
100Base-FX, 73 Gigabit Ethernet ports, or 24 FDDI ports, as well as 24
Packet-over-SONET (POS)/SDH (OC-3 or OC-12) ports.
Alcatel 7622 PDR
The Alcatel 7622 PDR provides 22 Gb/s of non-blocking bandwidth. A fully
loaded seven-slot chassis supports high performance switching at Layers 2, 3, 4
and 7, allowing port densities to 100 auto-sensing 10Base-T/100Base-TX, 100
100Base-FX, 30 Gigabit Ethernet ports, or 10 FDDI ports, as well as 10 POS/SDH
(OC-3 or OC-12) ports.
High performance routing
The Alcatel 7652 PDR provides wire-speed, packet-by-packet routing throughput
of more than 37.2 Mpps (14.8 Mpps for the 7622 PDR) for IP and IPX traffic via
standards-based routing protocols. The routers' cacheless routing engines
support more than 256 K MAC or IP routes per port. For the Alcatel 7652 PDR,
this equates to 6.4 million subnet routes per chassis (2.56 million for the 7622
PDR) - more than enough to accommodate the largest networks.
Parallel access shared memory
PowerRail routers use Alcatel's reliable ASIC-based parallel access shared
memory architecture, which allows them to deliver wire-speed multicast traffic
without affecting overall performance. The parallel access shared memory
architecture is superior to traditional shared memory architectures in that its
non-blocking design provides every port with simultaneous full access to a
central shared memory. Memory is allocated to each port according to demand,
providing a highly efficient use of router resources.
Mission-critical reliability
The modular design offers future-proofing, simple field-serviceability, and
product flexibility. All key components exist independently, are optionally
redundant, and are hot swappable.
Application-enabled networking
The Alcatel 7652 PDR incorporates unique "best-of-breed"
characteristics that provide quality of service functionality for your network
through MPLS/RSVP, DiffServ and programmable bandwidth queuing. Using the
ability to perform wire-speed analysis of Layers 2, 3, 4, and application
attributes, the Alcatel 7652 PDR can route traffic according to a broad set of
management policies that enable application-based filtering, access control list
(ACL) features, wire-speed accounting, bandwidth on demand, policing and rate
shaping.
Continuous investment protection
The PowerRail product line leverages your current hardware investment and
provides smooth expansion and migration well into the future. The size,
modularity and variety of interfaces available for the PowerRail routers assure
that they will scale as your network grows. Alcatel even provides gigabit
interface card (GBIC) transceiver cards for the Alcatel 7652 and 7622 PDRs.
Furthermore, the interface modules for the Alcatel 7652 PDR fit into the smaller
Alcatel 7622 PDR, enabling flexible network design as networking requirements
change.
Superior forwarding rates, scalability, and mission-critical resiliency
features make the PowerRail product line the ideal solution for improving the
performance of any network.
