Network planners believe that maximizing revenue and

minimizing cost is best achieved through the consolidation

of network elements, which in turn leads to increased

overall network efficiency. The Alcatel-Lucent 1671 SC

provides a path for central office and network optimiza-

tion by offering the features and densities needed to achieve

these goals. The MSM is available on all new Alcatel-

Lucent 1671 SC systems or can be added, in service, to

all existing Alcatel-Lucent 1671 SC systems via a simple

plug-in unit replacement, as illustrated in Figure 3.

The 80G center stage can be

easily swapped out for the new

240G center stage, while the

new 20G end stage cards, shown

in blue, replace the functionality

of the previously discrete 5G link

end stage cards and switching

cards, shown in yellow and

green respectively. This allows

the Alcatel-Lucent 1671 SC to

offer 4,608 STS-1 equivalents in

only two seven-foot racks, with

Copy 0/Copy 1 redundancy, far

outclassing the density of

competitors’ devices.

Flexible Matrix

In addition to a full range of inter-

faces, the Alcatel-Lucent 1671 SC

promotes network versatility by

supporting a variety of network

topologies. As a multiservice cross-

connect, the Alcatel-Lucent 1671 SC

offers a valuable solution for multi-

protocol networks. As versatile as

it is efficient, the Alcatel-Lucent

1671 SC provides VT1.5, DS0 and

STS-n grooming, enabling carriers

to maximize the productivity of

their infrastructure.

Figure 4 illustrates how various pro-

tocols at differing bandwidths are

switched by the non-blocking and

versatile MSM. For example, the

green line, which enters the I/O card

as a DS3 wideband signal, is provi-

sioned as a VT1.5 channel to pass

through the MSM. After switching

and multiplexing, it is represented as

a DS3 at the output. Correspondingly,

the blue line enters an I/O card as an

OC-12c signal which is then software

provisioned as a broadband STS-12c

clear channel. After switching, it is

presented at another output as an

OC-12c. For narrowband switching,

the red line illustrates the entry of

an OC-n signal that is software

provisioned as VT 1.5 with DS0

grooming. The MSM hands off the

VT signals to a dedicated DS0 switch

matrix that completes the switching

and then hands the signals back to

the MSM. In this example, the

narrowband signals are multiplexed

to a DS1 output. All of these connec-

tions are internal and implemented

via software commands.

Enhanced Data Shelf

The multiservice capabilities of the Alcatel-Lucent 1671 SC make it possible

to extend the data network closer to the customer and to support adaptation

to a unified multiprotocol label switching (MPLS) core. This allows the service

provider to make more efficient use of expensive router ports provisioned for

the delivery of data services, which leads to increased cost efficiencies. In fact,

with a reduced delivery cost, it may be possible to extend services to areas

where, in the past, it was not economically feasible to do so.

The Enhanced Data Shelf (EDS), illustrated in Figure 5, supports data

applications such as data aggregation, Layer 2 switching and circuit emulation.

By providing full SONET and data interworking, the Alcatel-Lucent 1671 SC

can support legacy functionality now, and incrementally switch capacity over

to data functionality as new services come on line; or it can be immediately

commissioned as a data transport solution. The EDS accepts signals that

include, but are not limited to, Gigabit Ethernet, clear channel and concate-

nated payloads, DS1, DS3, and OC-3 to OC-192 SONET; and this includes

any-to-any connectivity.

Impressive Return on Investment

The driving forces for next genera-

tion networks are the maximization

of return on investment through the

reduction of CAPEX and OPEX, and

the expansion of the range of services

offered to end customers. The Alcatel-

Lucent 1671 SC eases the migration

from traditional services to the new,

advanced services by safeguarding

existing revenues from legacy services

while simultaneously enabling new

revenue streams. With the Alcatel-

Lucent 1671 SC, I/O bays are inter-

connected using standard optical

interfaces, simplifying installation.

This means that racks can be remotely

deployed, reducing space constraints

and increasing deployment flexibility.

Fewer bays with more flexibility

decrease both OPEX and CAPEX,

and the on-board OC-48 interface

provide the opportunity to reduce the

numbers of multiple leased circuits

running at lower speeds.

Dynamic Grooming

The 240 Gb/s MSM switching fabric

on the Alcatel-Lucent 1671 SC allows

managed. Although new, cutting-edge

technology is important to service

providers, simplicity is still a focus.

The dynamic switching subsystem of

the Alcatel-Lucent 1671 SC creates

an efficient scenario where traffic is

categorized into narrowband, wide-

band or broadband as it traverses the

cross-connect, thus eliminating any

unnecessary grooming and the

associated cost.

10 Alcatel-Lucent 1671 Service Connect

Intelligent Network Adaptability

Next generation networks feature

intelligent network elements capable

of communicating on a common

plane for the purposes of optimizing
