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 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.
®
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.

Applications
The wide array of Physical Layer Modules and
Protocol Modules supports old and new applications
alike. On the user side, legacy interfaces such as
V.35/EIA-530 Packet and T1/E1 CBR protect your
investment in existing routers, codecs, LAN switches
and PBXs. Interfaces such as HSSI, T3/E3 and
OC-3c/STM-1 ensure support for newer bandwidthintensive applications.
On the network side, AACs connect to WANs at
speeds ranging from T1/E1 to OC-3c/STM-1. And to
fi ll the gap between T1/E1 and T3/E3, ATM Forumcompliant Inverse Multiplexing for ATM (IMA) is
available. The IMA module aggregates up to eight
T1 or E1 lines into a single, logical link operating
at up to 16 Mbps. The module uses a round-robin
algorithm to divide traffi c evenly across multiple
links. Furthermore, if one or more links fails, the
traffi c is automatically redistributed among the
remaining links, providing redundancy in the network.
The AAC family also offers numerous options for
each protocol. For ATM UNI, both the Cell Protocol
Module (PM) and the Enhanced Shaping Cell PM
are available. The Cell PM is optimized for full
throughput on high-speed private networks and
local router or switch interfaces. The Enhanced
Shaping Cell PM is designed for use with public ATM
services, shaping each connection to ensure the
traffi c complies with carrier service level agreements.
Multiple PMs are available for Frame Relay services,
ATM DXI, PPP and HDLC packet traffi c. The Quad
Packet and Quad Packet/CBR PMs support packet
traffi c over T1/E1 and low-speed V.35. The Packet
PM supports packet traffi c over T3/E3, HSSI, and
high-speed V.35. All PMs support Frame Relay
Link Management and Frame Relay-to-ATM Service
Interworking (FRF.8) and Network Interworking (FRF.5).
For circuit emulation, there are four or eight ports
of structured or unstructured data transfer options.
The Quad Packet/CBR PM supports up to four ports
of unstructured circuit emulation on T1/E1 or V.35.
The Octal CES PM supports up to eight ports of
structured or unstructured T1/E1, up to four ports
of unstructured V.35 or one port of unstructured
T3/E3 or HSSI. The Octal CES PM also supports an
Adaptive Timing option.
The Ethernet PM and PLM pair supports RFC
1483/AAL5 bridging with the Spanning Tree
Protocol. The modules are designed for full-speed,
point-to-point Ethernet connections over ATM.

include an embedded SNMP agent and standard

management systems. You can also Telnet to the
devices via the Ethernet port on the Integrated
System Controller or an in-band ATM/Frame Relay
connection. The native user interface is menu
driven, making port and connection confi guration
quick and easy.
Performance Monitoring
AAC systems collect extensive statistics, including
port and cell utilization, cell and packet discard, and
physical line errors. You can view the information
in table or graphical form. With this information
you can monitor network performance, anticipate
growth in bandwidth requirements and troubleshoot problems in both the local and wide area
Traffi c Management
You can maximize the utilization of expensive
wide-area bandwidth with AAC traffi c
management features. The Enhanced Shaping
networks. The products also support a full range
of loopbacks including line, local, and payload. In
OC-3/STM-1 networks, you can insert BIP and AIS
errors to test sections of that link.
Cell Protocol Module performs traffi c shaping on
a per-VC and per-VP basis, ensuring that traffi c
meets the rates contracted with your carrier. This
prevents cell discard and retransmissions, improving
the overall use of available bandwidth. Connections
exit the module through a weighted-fair queuing
(WFQ) mechanism that ensures each connection
gets scheduled bandwidth, even in the presence of
congestion. The system uses early-packet discard
(EPD) to reduce congestion quickly and to maximize
network utilization.
Other AAC modules increase bandwidth utilization
by reallocating idle CBR bandwidth. The Octal
CES module monitors the CAS voice on/off hook
status and V.35/CBR handshake signals. When a
Standards Compliance
AAC products comply with the relevant standards
of the ATM Forum, ITU-T, Bellcore/Telcordia, the
Frame Relay Forum, and the SMDS Interest Group.
This alleviates compatibility issues in multi-vendor
networks and reduces the risks associated with proprietary solutions.
