Alcatel-Lucent 7705 SAR
SERVICEAGGREGATIONROUTER|RELEASE1.0
The Alcatel-Lucent 7705 Service Aggregation Router (SAR) delivers industry-leading IP/MPLS and pseudowire
capabilities in a compact platform that has the ability to groom and aggregate multiple media, service and
transport protocols onto a normalized, economical packet transport infrastructure.
The Alcatel-Lucent 7705 SAR is extrem-
ely well suited to the transport needs of
the evolving mobile radio access net work
(RAN). The platform delivers strong
convergence capabilities in the mobile
RAN with native service processing of
2G, 3G and 4G traffic. In addition, the
platform can provide a powerful solution
for wire line aggre gation and routing in
carrier and enterprise applications. For
example, the Alcatel-Lucent 7705 SAR
can be deployed in a T1/E1 private
line multiplexing environment.
The Alcatel-Lucent 7705 SAR owes
much of its development heritage
to the Alcatel-Lucent Service Router
(SR) product line. Sharing much of
the market-leading feature set of that
product, the Alcatel-Lucent 7705 SAR
brings a powerful, service-oriented
capability to the RAN, but in a form
factor and at a price point that are
particularly appropriate for cell sites
and hub locations. With end-to-end
service management under the
Alcatel-Lucent 5620 management
portfolio, the Alcatel-Lucent 7705 SAR
greatly augments the IP/MPLS RAN
transport solution from Alcatel-Lucent.
Industry-leading scalability and density
is provided in the 8-slot, two rack unit
(RU) version that supports up to 96 T1/E1
Any Service, Any Port (ASAP) ports. On
the network uplink side, media connec-
tivity options are: Ethernet, Fast Ethernet
(FE), Gigabit Ethernet (GE), or n xT1/E1
Multi-Link Point-to-Point Protocol
(MLPPP). The platform can be option-
ally configured with a redundant core
control module and uplinks. The
Alcatel-Lucent 7705 SAR-8 has eight
slots; two are allocated for control
and switch modules (CSMs), with the
remaining six being available for user
traffic adapter cards. The Alcatel-
Lucent 7705 SAR has a compact modular
architecture, constructed to allow
flexible use of line adapter cards so
operators can optimize the configura-
tion to meet the specific requirements
of a site.
With the modular architecture comes
additional resilience and flexibility.
The solution can optionally support
1+1 fully redundant CSMs. Each adapter
card has dual paths to the active and
standby CSMs. Each of the six adapter
card slots can be used for any adapter
card type, removing the burden of
complex pre-engineering and future
scenario planning. The two adapter
card types supported in Release 1.0 are
a 16-port ASAP T1/E1 adapter card and
an 8-port Ethernet adapter card.
