SMA1/4UC, Marconis new, cost-effective, multiservice,

metro edge device

Evolution at the network edge

SMA1/4UC Data Sheet

With networks in transition from voice to data, a

device that can enable the change seamlessly byfunctioning effectively in both domains is a key benefit.SMA1/4UC is such a device, using the resilience ofSDH to deliver both Ethernet and PDH services cost-effectively in metro edge/access network applications.

The versatility and integration of SMA1/4UC

creates a simple, low-cost unit for network

edge and premium-customer applications.

Sharing cards with our Series 4 range, and

making use of small-form-factor-pluggable

optical interfaces on line and data interfaces,means that the operational benefits are

equally compelling.

Applications

Multiservice delivery platform

SMA1/4UC constructs multiservice delivery

rings or spurs operating at STM-1 or STM-4.

The high-capacity switch and high-density

interfaces provide low-cost hubbing nodes

where consolidation close to the edge of the

network increases the efficiency of the higher

layers.

Multi-tenant buildings

In multi-tenancy buildings, on business parks

or campuses, SMA1/4UC distributes multiple

services from the existing SDH infrastructure

either as a hub, in customer rings or in dual-parenting loops. Where data security is a

strong consideration, SMA1/4UC provides

low-cost rings with nodes hubbing from

suitable roadside cabinets, or from operator-

controlled equipment rooms, to terminal units

inside the customer premises.

Fixed and mobile radio backhaul

In fixed and mobile radio applications,

SMA1/4UC ensures economical backhaul

solutions, as a very compact (6U) device with

high-density 2 Mbit/s interfaces and with

STM-1 electrical SFP line interfaces reducing

interfacing costs in the associated radio

equipment.

Major customer premises

The SMA1/4UC provides an economical yet

flexible solution for premium customers with

the need for service variety coupled with high

levels of security. It delivers a wide range ofservices including Ethernet LAN, 2 Mbit/s

and other PDH circuits, together with STM-1

and STM-4. With card/unit protection

supplementing network protection, and with

a subrack that can be mounted vertically or

horizontally, SMA1/4UC provides high levels

of functionality whilst making best use of

available space.

The SMA1/4UC is suited to the delivery of both dataand TDM services in varying volume and mix

Key features

Data

The PacketSpan range of Ethernet tributaries

gives access to revenues for the provision of

Ethernet services: Ethernet Private Line,Ethernet Virtual Private Line, Ethernet Virtual

Private LAN and Ethernet Internet Access. A

PacketSpan tributary card also provides

Layer 2 aggregation into a Gigabit Ethernet

port. SMA1/4UC can also act as a hub for

optical Ethernet distribution. The platform

has the capability to deliver up to

16 x 10/100M Ethernet ports together with

63 x 2 Mbit/s into an STM-4 ring, resulting in

a very low cost per interface.

VC-12 switch capability

The SMA1/4UC has a high-capacity VC-12

switch (26 x STM-1) providing the flexibility ofhigh-hubbing capacity in a very small, low-

cost package.

SFPs hot-pluggable for convenience

and flexibility

SFPs provide a rugged solution for reliable

installation and upgrade. They also offer

increased flexibility plug any interface into

the line aggregate socket on card:

STM-1 (S1.1, L1.1 or L1.2)

STM-1 electrical

STM-4 (S4.1, L4.1 or L4.2)

The same SFPs are used throughout our

portfolio of next-generation SDH platforms,

resulting in reduced inventory cost and

spares holding.

In-service upgrade

To relieve bandwidth bottlenecks without

installing new equipment, SMA1/4UC can be

upgraded from STM-1 to STM-4 in service

and with significantly reduced installation

time due to the use of SFP interfaces offering

savings in time and incremental cost.

An additional SFP interface can easily be

added incrementally to a core card to act asa tributary, or in an LTE application to add

line protection in customer premises.

Tandem Connection Monitoring

TCM provides valuable performance visibility

for the monitoring of connections between

operator boundaries. This also offers faster

location of faults through isolation of

problems to particular network segments.

Data Communications Network

Solutions

SMA1/4UC has two options that allow

management of DCN communications

without the need for external network

equipment.

For remote management of SMA island

networks, the VC-4 path overhead

(F2 byte) provides a management

communications channel across an Other

Licensed Operator network.

For remote management of third-party

equipment, IP tunnelling provides a

management channel via an auxiliary

Ethernet port.

Protection

The SMA1/4UC provides a range of

equipment and traffic protection options,

including:

Network protection, SDH line and

tributary

MSP protection

Sub-Network Connection protection

Card protection

Core switch/line unit

SDH & PDH tributaries 1+1

System architecture

Each powerful core module provides a

housing for two STM-1 or STM-4 SFP

line interfaces and a full-connectivity

VC-12/VC-3/VC-4 switch with 26 x STM-1

equivalent capacity.

Cross-connection may be between line and

line, between line and tributary or between

tributary and tributary.

Configuration, performance, error and alarm

monitoring are available centrally via the

network management system or locally via

the Local Craft Terminal.

Access and security management can be

programmed to provide various levels of

operator access.

Embedded software can be downloaded for

feature enhancement in service. In addition,

the multiplexers can report details of their

inventory status from non-volatile memory,

either locally or remotely.Mechanical description

The subrack can be mounted vertically or

horizontally with a plug-in fan tray used in the

horizontal position. Horizontally mounted, the

6U height is a major advantage where space

is at a premium.

The subrack, with its integrated line and core

units, can provide a protected STM-1 or

STM-4 ADM system and accommodate

various combinations of line and tributary

cards. All external connections are front-

access for ease of installation and

maintenance.

Each module within the shelf has its own

front panel for robustness, whilst meeting the

necessary EC directives for EMC and ESD

compliance.

Mounting options

one vertically

two side-by-side

one horizontally in a 6U high slot
