• Category 5 balanced cable: Gigabit Ethernet interface, supporting 1000Mb/s data rate as specified in IEEE 802.3, clause 40 (1000BASE-T).

Note: 1000-Mb/s data rate is assumed to be split onto four pairs of cable (per direction), each working at 250 Mb/s.

• The maximum link length supported by 100BASE-T interface depends on the characteristics of the cable used; minimum target is 100 m.

• The maximum link length supported by 1000BASE-T interface with CAT 5 balanced cable is > 100 m

• RJ-45 connector is supported for RX/TX differential connectivity (MDI connectivity)

• Standard load impedance to be considered for transmitter/receiver characteristics evaluation is 100 ohms

• When operating as 100BASE-T, an internal 4B/5B block coding is supported in order to convert the 100 Mb/s data rae (at MII) to the 125-Mb/s line rate (at MDI)

• No line coding block is supported when operating as 1000BASE-T.

DWDM channelsIntroduction


............................................................................................................................................................................................................................................................

DWDM channels

1850 TSS-320 and 160 support the transport of DWDM channels at 10 Gbps. The exact data rate depends on the particular mapping of the client. For details, refer to “DWDM interface at 10Gbps” (p. 1-10).

The DWDM system is based on the 100 GHz channel spacing in the C-band, according to the ITU-T G.694.1 Rec. In current release, the 16 channels of the L1 and L2 bands are supported. The optical spectrum is shown in next Table 1-7 (ITU-T standard grid). It is anchored to the 193.1 THz reference

The engineering rules are designed to accommodate all line rates available in PP10GSO and PP10GE. They can be equipped with 16 different XFPs, each one tuned on one DWDM channel/wavelength.

A DWDM channel must be regenerated if the OSNR or Dispersion limits are exceeded. One DWDM unit is required to regenerate each direction of transmission.

Main DWDM features

System Capacity

16 channels, belonging to L1 and L2 bands. Refer to Table 1-7, “DWDM frequencies allocation plan in C-band” (p. 1-16) for details.

Application

The NE supports point to point applications.

Optical Supervisory Channel (OSC)

OSC is not supported. Each node has a local DCN address.

Amplifier tuning

Amplifiers are tuned with a constant output power. The output power depends on the numbers of channels, as shown in the following table

............................................................................................................................................................................................................................................................

Minimum number of channels

As amplifier tuning is not linear down to 1 channel, in order to avoid critical non linear effects, the minimum number of channels should be limited.

If transmission with 1 channel is mandatory, it is required to place fixed attenuators at each span input, so reducing span budget.

Chromatic Dispersion mapping

The DCM are placed in the amplifiers interstage in order to compensate about 90% of each span. Pre-compensation should be 30Km DCM when possible

Transponders interworking

Each wavelength must be originated and terminated by transponders of the same technology. As PP10GSO and PP10GE are the WDM tributaries and the technology is the same, they can interwork.

The interstage of each amplifier must be adjusted according to the previous span loss (including the fixed attenuators). The following rule applies the 22/09 amplifier:

• GAIN + INTERSTAGE = 37 dB

The gain corresponds to the loss inducted by the previous span, plus the fixed attenuator (if used).

A General on Customer Documentation

Products, product–releases, versions and Customer Documentation

A product is defined by the network hierarchical level at which it is used and by the whole of performance and services for which it is meant.

A product evolves through successive product releases, which are the real products marketed for their delivery at a certain release availability date. So, a product release defines a set of hardware components and a software package which, as a whole, identify the possible network applications and the equipment performance for which the specific product release has been designed, engineered, and marketed.

In some cases, a product release has further development steps, named versions, that are introduced to improve or add some functionality (mainly software) over to the previous version, or for bug fixing purposes.

A product release has its own standard Customer Documentation, composed by one or more documents.

A new version of a product release may or may not produce a change in the status of the Customer Documentation set, as described in Section “Updating document” (p. A-2).

Document supply to Customers

Documents are not automatically delivered with equipment with which they apply. The number of documents per unit to be supplied must be decided at the contract level.

............................................................................................................................................................................................................................................................

Aims of standard Customer DocumentationGeneral on Customer Documentation

A-2 PN 8DG 08763 GAAAIssue 1 March 2009

............................................................................................................................................................................................................................................................

Aims of standard Customer Documentation

Standard Customer Documentation, referred to hereafter, is always meant as plant–independent.

Plant–dependent documentation, if specified by the contract, is subject to commercial criteria based on content, format, and supply conditions. Plant–dependent documentation is not discussed in this document.

Standard hardware and software documentation is meant to provide customers with the information necessary to install, commission, operate, and maintain the equipment according to ALCATEL-LUCENT Laboratory design choices.

In particular, the content of documents associated with software applications focus on the explanation of the man–machine interface and the operating procedures allowed. Maintenance is covered to the faulty PCB location and replacement level.

Consequently, design documentation (like PCB hardware design and production documents and files, software source programs, programming tools, etc.) is not supplied to customers.

Hardware-specific documents (usually the "Technical Document") and software-specific documents (usually the User Provisioning Guide, see “Related information” (p. 1-x)) are not part of the standard documentation set because they are not necessarily impacted by product changes.

For example, only the Technical Document might be revised because of hardware configuration changes (for example, replacing one unit with another that performs the same function but has a different P/N).

On the other hand, the User Provisioning Guide, see “Related information” (p. 1-x), may be updated because of a new software version. Changes in software versions do not impact the Technical Document as long as it does not imply hardware modifications.

Both document types can be updated to improve content, correct errors, etc.

Updating document

The documents associated with this product release are listed in “Related information” (p. 1-x). Each document is identified by:

• the name of the product–release (and version when the document is applicable to the versions starting from it, but not to the previous ones)

• the document name• the document Part Number (P/N)

Updating documentGeneral on Customer Documentation


A-3

............................................................................................................................................................................................................................................................

• the document edition (usually first edition=01)• the document issue date. This date on the document does not refer to the date of print

but to the date on which the document source file was finalized and released for the production.

Changes introduced in the same product–release (same document P/N)

The edition and date of issue might change on future document versions for the following reasons:

• only the date changes (pointed out in the Table of Contents) when modifications are of an editorial nature and do not change the technical content of the document.

• the edition, hence the date, is changed because modifications impact the technical content. In this case:– the changes from the previous edition are listed in “Reason for revision” (p. 1-ix)– revision bars on the left of the page in updated chapters indicate modifications in

text and drawings

Changes that impact the technical content of the document cause the edition number to increase (for exmaple, from Ed.01 to Ed.02). For minor updates (for example, for corrections), documents retain thier edition but an extra letter is appended to the version (for example, from Ed.02 to Ed.02A). Version character/letters can also be used for draft or proposal editions.

Supplying updated documents to customers

Supplying updated documents to customers who have already received previous issues is submitted to commercial criteria.

By updated document delivery, it is meant the supply of a complete copy of the document new issue (supplying errata-corrige sheets is not envisaged).

Changes due to new product version

A new product version changes the document P/N and the edition starts from 01.

In this case, the modified sections of the document are not listed.

NOTES ON DOCUMENTS RELEVANT TO SOFTWARE APPLICATIONS

Documents relevant to software applications (typically the User Provisioning Guide, see “Related information” (p. 1-x)) are not updated when the new software version distributed to customers implies man-machine interface changes or in case of slight modifications to procedures.

Moreover, screenshots and figures in documents do not run with releases; they are not updated to reflect current product release versions if the screens or figures are unchanged.

Customer documentation on CD-ROMGeneral on Customer Documentation


............................................................................................................................................................................................................................................................

Customer documentation on CD-ROM

In the following sections, 'CD-ROM' is used to refer to the 'Customer Documentation on CD-ROM'

Contents, creation and production of a CD-ROM

In most cases, a CD-ROM contains, in read-only electronic format, the documents for one product release (or version) for a particular language.

In other cases, a CD-ROM can contain documentation for different product releases (or versions) for a particular language.

As a general rule:

• CD-ROMs for Network Management products do not contain:

• Installation Guides

• documentation of system optional features and related software that are not available for purchase from ALCATEL-LUCENT

• CD-ROMs for Network Elements products do not contain:

• documentation of system optional features (for example, System Installation Guides for racks and related hardware) that are not available for purchase from ALCATEL-LUCENT

A CD-ROM contains guides and documents for a particular product/release in .pdf format. Bookmarks and hyperlinks are included to aid navigation. The resulting master CD-ROM is electronically transferred to the appropriate department for distribution to customers.

The information contained on CD-ROMs and in paper documents for a given product/release is identical.

Suitable checks are made to ensure a virus-free product.

Use of the CD-ROM

The CD-ROM can be used both in PC and UNIX WS environments.

The CD-ROM starts up automatically with autorun; the Index and other hyperlinks help navigate the documents. ReadMe notes are also included on the CD-ROM.

In order to open the .pdf documents, Adobe Acrobat Reader Version 4.0 (minimum) must be installed on your system. The customer is responsible for obtaining and installing the correct version of Adobe Acrobat Reader.

Once the correct version of Reader is installed, users have the option of reading the documents on their PC/WS, installing documents to their PC/WS, or printing all documents or selected documents/sections to a local printer.



A-5

............................................................................................................................................................................................................................................................

CD-ROM identification

Each CD-ROM is identified by the following:

a. external identifiers (imprinted on the CD-ROM):

– the name of the "product release(s)" (and "version" if applicable)

– text indicating the language(s)

– the CD-ROM Part Number)

– the CD-ROM edition (usually first edition=01)

• internal identifiers - a list of files and documents (with P/Ns and editions) included on the CD-ROM

CD-ROM updating

The list of source document P/Ns-editions indicated in the previous section (C.5.3 point 2), in association with the CD-ROM's own P/N-edition, is also loaded in the ALCATEL/LUCENT-INFORMATION-SYSTEM as a structured list.

Whenever a new edition of any document is released in the ALCATEL-LUCENT archive system, a check in the ALCATEL/LUCENT-INFORMATION-SYSTEM is made to identify the list of CD-ROMs that must be updated to include the new editions of these guides/documents.

This causes the planning and creation of a new edition of the CD-ROM.

Updating of CD-ROMs always follows, with a certain delay, the updating of the single documents composing the collection.
