1677 SONET Link

NEXT-GENERATION MULTISERVICE PLATFORM

Never before have businesses been under such pressure

to provide and support multiple high-bandwidth services

while continuing to support traditional revenue-generating

services. The Alcatel-Lucent 1677 SONET Link provides the

means to maximize bandwidth availability and to ﬁll that

bandwidth effectively.

Businesses have invested billions of dollars

in their SONET network infrastructures,

their operations systems, and the personnel

to run and maintain them. Customers,

both consumers and businesses, are now

demanding more services, more versatility

and more bandwidth, and these demands

are expected to continue to rise over the

next few years. Consequently, SONET

equipment is still called on to provide

transport for new and existing services.

Pressure for revenue growth means

that services must be deployed in the

here and now, without dramatic changes

to the network topology or to operational

methods. To fully use and expand the

capabilities of SONET, next-generation

transport solutions must be able to

aggregate disparate native channels at

differing bit rates, groom these signals

seamlessly, and then efﬁciently ﬁll the

transport “pipes”.

The Alcatel-Lucent 1677 SONET

Link (SL) fulﬁlls these requirements

by combining the functions of legacy

SONET add/drop multiplexers (ADMs),

the bandwidth-grooming capability of

narrowband, wideband and broadband

digital cross-connects, and the optical

ﬁber-sharing of dense wavelength division

multiplexing (DWDM). The Alcatel-Lucent

1677 SL offers best-in-class port densities

combined with the scalability that is

necessary for gradually adding more

services. What’s more, this class-leading

feature set comes at a realistic price.

YOUR NEEDS

Most operators have sufﬁcient ﬁber in the

ground to support current and near-future

needs, provided that the ﬁber is used

effectively. In situations in which more

bandwidth is needed, they know that Alcatel-

Lucent has a full range of state-of-the-art

active and passive coarse wavelength

division multiplexing (CWDM) and DWDM

devices. What operators want is a network

element (NE) that leverages the existing

network, offers data and other services

via this network, and grooms signals at

the network edge. The NE must produce

substantial cost savings over incumbent

equipment by providing signiﬁcantly

increased switching capacity and port

density, while at the same time controlling

heat output and power usage.

Legacy equipment makes it difﬁcult for

businesses to scale their networks to meet

ever-changing demands for increased

capacity and new high-bandwidth services.

Upgrading the capacity of a traditional

SONET ring can be a time-consuming

and expensive process, often requiring

the replacement of thousands of dollars’

worth of equipment. Deploying new rings

could be even more complex and difﬁcult

to manage, with even further investment

in additional central ofﬁce equipment to

terminate the ring and to switch trafﬁc

throughout the network.

As a next-generation SONET solution,

the Alcatel-Lucent 1677 SL eliminates

scaling-limitation issues and additional

ring-upgrade complexity. The Alcatel-

Lucent 1677 SL provides for future expan-

sion as bandwidth needs grow within

metropolitan and regional networks. When

a new service offering is created, Alcatel-

Lucent clients can increase support for

hundreds of subtended rings from the

same NE and from a variety of interfaces,

to support the myriad offerings that they

will want to provide.

The ability to grow networks with

an installed base of equipment provides

businesses with rapid returns on their

investments and saves operational and

engineering expenses. Key functionality,

such as OC-192, VT1.5 grooming and

transmultiplexer support, allows Alcatel-

Lucent clients to get ahead of their

competition when rolling out next-

generation services. On-board, point-to-

point DS0 grooming eliminates the need

for a second NE or for inter-machine

trunks. No competitor’s solution beats

the Alcatel-Lucent 1677 SL for integrated

functionality.

Scalability for Increasing Capacity

BANDWIDTH MANAGEMENT

Successful businesses efﬁciently manage bandwidth and network resources.

As large metropolitan and regional networks evolve to support hundreds

of rings and terabytes of capacity in a region, it is imperative that they

have the power and ﬂexibility to switch and groom end-customer services

in the most resource-efﬁcient way possible. This means taking small,

disparate feeds that are currently transported inefﬁciently and combining

them into appropriately sized trunks to maximize return on investment.

The Alcatel-Lucent 1677 SL grooms trafﬁc by taking circuits from

multiple interfaces and switching them onto one pipe for transport across

the network. The Alcatel-Lucent 1677 SL supports STS-n (n = 1 to 48c)

grooming to make the most efﬁcient use of the carrier’s network infra-

structure (see Figure 1). Additionally, two optional modules provide DS0

and VT1.5 switching capability, allowing ﬁne-grain bandwidth manage-

ment. Full-featured wideband and narrowband grooming are also possible

with this modest-sized platform using the transmultiplexing card, and

carriers may deploy this capability as needed.

In contrast to the traditional centralized model, the multi-ring termina-

tion and bandwidth-grooming capabilities of the Alcatel-Lucent 1677 SL

ﬁt the emerging optical network model that disperses bandwidth manage-

ment to the edge of the network.

INTEROPERABILITY

As businesses roll out new network equip-

ment, this equipment must be integrated

into their back-ofﬁce environments and

under their operations support systems

(OSSs), which provide provisioning,

monitoring and management of multiple

vendors’ NEs. Hence, the network manage-

ment architecture must provide standard,

user-friendly, open interfaces to allow

other third-party vendors to pick up sup-

port for the product. This enables them to

provide comprehensive management such

as end-to-end provisioning and monitoring

across multiple NEs. The Alcatel-Lucent

1677 SL is designed with the goal of

deployment in a carrier-class environment

and includes development for open inter-

faces for OSS integration. The Alcatel-

Lucent 1677 SL supports interworking

standards such as open systems inter-

connection (OSI) and target ID address

resolution protocol (TARP), and these

allow integration with other vendors’

systems.

MULTIFUNCTIONALITY

Any new capital expenditure must be

justiﬁed by increased revenues and prof-

itability, and the Alcatel-Lucent 1677 SL

provides these beneﬁts. For example, its

multi-ring feature allows numerous users

and circuits to be supported on one NE,

thus eliminating the need for multiple NEs

(see Figure 2). This decrease in equipment

use results in an immediate reduction

in CAPEX, followed by ongoing savings

in OPEX.

In addition to the valuable protection

and restoration capabilities of SONET, the

Alcatel-Lucent 1677 SL offers businesses

the opportunity to deliver Gigabit Ethernet

services. The Gigabit Ethernet interface

of the Alcatel-Lucent 1677 SL makes use

of leading-edge technology to permit the

transport of data services over the existing

SONET infrastructure. This capability

enables new revenue sources in return

for compellingly low deployment costs.

Alcatel-Lucent was one of the ﬁrst

vendors to support VCAT, the standard

that enables businesses to map Ethernet

directly onto a SONET network (see

Figure 3). VCAT enables these operators

to offer low-cost Ethernet services, while

maintaining all the beneﬁts of SONET

networking and without requiring drastic

changes to the network infrastructure

or operational systems.

GOING FROM STRENGTH TO STRENGTH

Alcatel-Lucent continues to invest heavily

in the development of the 1677 SL, winning

industry interest and customer satisfaction.

Recently added functionality includes

Gigabit Ethernet broadcast, dual-ring

interconnection, transmultiplexing without

the need for a vertical switch controller

(VSC), DS1 management integration, and

DS0 grooming. More is on the way for this

exceptionally ﬂexible and upgradeable

solution.
