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

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

Cabling

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

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

Cabling

Figure 5

Tie Up the New cable

Connect and cut the wires (one action using the KRONE LSA+ InsertionTool S, see Figure 6 on page 7) by placing the Insertion tool above the slit
(place the cutting end towards the connector’s center), and firmly press
towards the connector. Repeat this step for all wires.

Figure 6

Cutting and Connection a Wire

It is recommended to label the EDGE connectors with the same number as
the LAN cable and tie up the Exchange and Line EDGE connectors
together according to Figure 7 on page 8.

Tie Up and Label the EDGE Connectors

Cabling of Ethernet Connections
The EDN312 IP DSLAM is connected to the network with cat. 5 straight
through standard LAN cables.
The total cable length from a switch to the IP DSLAM must not exceed 100
m and must conform to category 5 standard for LAN cables.
Note:

The cable resistance must not exceed 8.5 Ω (one cable one way),
when the ECN310 switch and/or the ECN320 switch is used. When
EPN124 power nodes are used the resistance must not exceed 10
and ECN320 Ω (one cable one way).

The length of the LAN cable must be long enough to make it easy to mount
and dismount the IP DSLAM.
Typically the IP DSLAM is connected directly to an ECN310 switch, an
ECN320 Controller Node or an ECN108 switch. If the IP DSLAM is
connected to other switches, which does not supply power over Ethernet,
then the EPN124 Ethernet Power Node must be connected between the
switch and the IP DSLAM.

Mounting the IP DSLAM

Mounting the IP DSLAM
The illustration below shows how to mount the EDN312 after the subscriber
lines, exchange lines through the EDGE connector have been pulled.
The EDGE connector is removed from the bracket-tool and inserted in the
rear of the IP DSLAM. The IP DSLAM has been labelled with “line” on one
side and “exchange” on the other side.
After the EDGE connectors have been inserted the IP DSLAM is pressed
into place on the two rods in the subrack.

Verifying the Installation

Verifying the Installation
The purpose of the verification is to ensure the following:
•

No errors in the rewiring of the subscriber lines

•

The old services (POTS or ISDN) function

•

The physical installation of the EDA Access Domain nodes was done
correctly

•

The power and Ethernet connections function

•

It is possible to make an ADSL connection to a CPE modem

•

The registration in PEM has been done correctly

The following methods can be used for verification, each implying a
different level of verification and effort:
1. Verification without connection to PEM or any management system
2. Verification using the Local Craft Tool (LCT).
3. Verification using PEM.

5.1

Verification without Connection to PEM
It is not possible to activate the IP DSLAM by this method. It is the least
time consuming method but also gives the least assurance. This method
involves the following:

Comments

Perform continuity check on each line from
the Exchange MDF to the Line MDF

Best to perform after rewiring and
before installing nodes

Verify (if possible) that the ECN320 switch
port where the IP DSLAMs are connected,
indicates active Ethernet connection

Active Ethernet connection is
verified

Recommended to perform continuity check
on each POTS or ISDN line

Test that the new installation has
not affected the old services

Verifying the Installation

5.2

Verification with the Local Craft Tool
The LCT can be used without a connection to PEM or to any backbone
network as described in section section Error! Reference source not
found. on page Error! Bookmark not defined..
The LCT activates the IP DSLAMs (as well as providing an IP address to
other nodes) and configures each IP DSLAM to start all the lines, and by
using a CPE modem on each line, it is possible to verify that the ADSL
connection is up and running. The registration process cannot be verified
by using this method. Using the LCT is more time consuming than method
1, but not as time consuming as method 3.

The ECN320 Local Craft Tool
When the EDN312 IP DSLAM is embedded in an EAN as for example the
EDN288 and connected to the ECN320 Ethernet Controller Node the line
verification is done by means of the ECN320 Local Craft Tool. The ECN320
Local Craft Tool is an application used for checking the function of each IP
DSLAM embedded in an EAN. When the ECN320 LCT has been
connected to the ECN320 the line verfication is done by activating a line
configuration script placed on the LCT, so the user starts a Windows
Command Prompt, navigates to a folder with the script and activates the
script. The following steps are taken:
1. Copy the 24 standard (“empty”) configuration files from the ECN320
flash disk to a folder on the LCT. The files are needed when reverting
to the initial state.

Verifying the Installation

2. Copy 24 configuration files with line configurations from the LCT tool to
the ECN320 flash disk.
3. Restart the embedded IP DSLAMs by using the Command Line
Interface (CLI)
4. Test the ADSL lines by connecting a CPE modem to each line one at a
time. The LCT has an SNMP Notification Receiver, which enables the
user to receive traps from the embedded IP DSLAMs.
5. When the test is finished the initial, standard configuration files are
copied back to ECN320 flash disk.
6. Finally the embedded IP DSLAMs are restarted from the CLI.

Verfication of the ADSL Lines with the LCT

The ECN320 has by default 24 standard configuration files installed on the
flash disc. The files are “empty”, which means that they do not contain any
line configurations. The LCT has been installed with 24 configuration files
containing line configurations.

5.3

Verification Using PEM
This is the most time-consuming method, and the only method, which gives
100% verification. Verification of the ADSL connection is done by
configuring an end-user with a service in PEM for each line.

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

Verifying the Installation

This method is similar to activating real subscribers. In order to use this
method the following preconditions have to be fulfilled:
•

The PEM installation has succeeded

•

The PEM configuration of the network has been done

•

The servers in the network are running

•

All registration has been transferred to the PEM

The Service Configuration Manager is used for this task.
Alternatively the Bulk Configuration Manager can be used instead of the
Service Configuration Manager and may simplify the task of configuring an
end-user with a service for each line; please see the Bulk Configuration
User’s Guide for further details.
Please refer to Local Craft Tool User’s Guide and the PEM User’s Guide for
detailed information of how to use them.
