1 Introduction

This guide describes how to install the Ethernet DSL Access (EDA) IP

DSLAM EDN312.

The guide is intended for installation and maintenance personnel.

An overview of the installation process of a complete Access Domain is

described in the Access Domain Installation Guide.

The reader should have a basic understanding of the Internet Protocol (IP).

The guide can be read separately, but for a full understanding of the EDA

system the reader is referred to the System Overview.

The guide can be printed on a monochrome printer, but illustrations are

easier to understand if a color printer is used.

1.1 Revision History

The guide is valid for EDA 1.3. Please refer to the Release Notes for valid

versions of the EDN312 IP DSLAM and the application SW. Other product

versions with functions not described in this guide may be available.

Environmental and Space Requirements

2 1/1531-HSD 101 41 Uen A 2004-01-30

2 Environmental and Space Requirements

The 12-line IP DSLAM (EDN312) complies with the following standards

regarding storage, transportation and operation. The operation category is

also designated stationary in-use at weather-protected locations.

• ETS 300 019-2-1: Storage, class 1.2

• ETS 300 019-2-2: Transportation, class 2.3

• ETS 300 019-2-3: Operation, class 3.2

• GR-63-CORE Section 2.9.4 (-40°C to 65°C) for non-environment

controlled equipment housings (Outdoor cabinet installation).

The storage class 1.2 means tested for storage in weather-protected area,

not temperature-controlled.

The transportation class 2.3 means tested for public transportation.

The operation class 3.2 means tested for partly temperature-controlled

location.

Caution!

The temperature within a rack assembly may be higher than the ambient

room temperature. Check that the rack environment temperature is within

the specified operating temperature range.

The EDN312 can be mounted in Ericsson subracks prepared for installation

in a 19” or ETSI rack. This includes micro subracks, small subracks and

medium subracks. For detailed information, please see the Subracks

Installation Guide. The EDN312 is also used in an EDN288 IP DSLAM and

for additional information, please see the EDN288 Installation Guide. The

EDN312 can also be mounted in a Outdoor cabinet and for specification

and installation details please see the Outdoor Cabinet Installation Guide.

Mounting in the rack must be done in such a way that there is sufficient

space to allow airflow around the EDN312 as shown in Figure 1 on page 3.

Environmental and Space Requirements

1/1531-HSD 101 41 Uen A 2004-01-30 3

The distance between the IP DSLAMs must be at least 20 mm so that an IP

DSLAM can be dismounted without interfering with the adjacent IP

DSLAMs.

3 Cabling

3.1 Cabling of Subscriber Lines

Before the IP DSLAM is mounted the connections between the Line MDF

and the Exchange MDF have to be rewired. The wires are disconnected,

and then reconnected through typically a Broadband MDF and the EDA

System according to planning.

3.1.1 Cabling Lines

The following description explains how to rewire the connections between

the Line MDF and Exchange MDF through the EDGE connectors.

Figure 2 on page 4 shows the subscriber line connections through the

EDGE connectors both for exchange and line side.

3.1.2 Wiring EDGE Connectors

It is recommended to follow the “Best practice” wiring procedure when

wiring the EDGE connectors.

The EDGE connector can be mounted by using a Tool Kit. The kit consists

of a wiring bracket-tool and an LSA+ inserter-tool. Figure 3 on page 5

shows how to mount the wiring bracket-tool on the rods in a subrack.

Figure 3 Mounting the Wiring Bracket-Tool

The EDGE connectors must be mounted as shown in Figure 4 on page 6.

The wiring bracket-tool ensures that the cables are long enough so that the

IP DSLAM can be dismounted by pulling it out. In case the wiring bracket-

tool is not used, it is important to ensure that the cables are long enough.

Figure 4 Mounting the EDGE Connectors

Strip approximately 20 cm off the new cable and tie it up with a cable tie to

the existing cable as illustrated in Figure 5 on page 7. Alternatively, make a

loop around the cable guide.

Note: It is recommended to use 0.4 mm thick wiring cables
