Description
The AAC family offers a fl exible, modular
architecture, allowing you to choose the most
cost-effective service for each application and
manage everything from a single platform. Each
AAC contains slots for Protocol Modules (PM) that
determine the traffi c type—ATM, Frame Relay or
Ethernet—and Physical Layer Modules (PLM) that
determine the physical interface. The broad array
of available Protocol and Physical Layer Modules
meets the needs of a variety of customers,
including enterprise, service provider, government
and military.
The AAC family comprises three models to deliver
a full range of access options at a variety of price
points.
The AAC-3 offers the highest levels of
connectivity and scalability, supporting speeds
ranging from T1/E1 to OC-3c/STM-1. Its
modular chassis supports up to seven PM/PLM
pairs, making it an ideal hubbing device for
enterprise networks or a port fan-out device
for service distribution.
The AAC-2 provides economical integration
of services over public and private networks at
speeds ranging from T1/E1 to OC-3c/STM-1. Its
smaller chassis supports up to three PM/PLM
pairs, making it suitable for mid-sized locations
that need to connect voice, video and data
traffi c to the WAN.
The CellSMART 200 IMA series is ideal for
medium- to high-speed data applications
that require NxT1/E1 access using Inverse
Multiplexing for ATM (IMA). A variety of
models are available with V.35, HSSI,
Ethernet, T3/E3 or OC-3c/STM-1 user ports.
The high port density and modular architecture lets
each network grow and upgrade at a minimal cost.
As service or application needs change, customers
just add or switch modules while maintaining
a common chassis and management interface.
For instance, using an Octal IMA Physical Layer
Module, you can steadily add T1/E1 circuits as your
bandwidth needs increase. When eight T1 or E1
lines become insuffi cient, you can switch to a T3/E3
Physical Layer Module. You do not need to replace
the Protocol Module, because it can now be paired
with the new T3/E3 Physical Layer Module.
