5 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:
Table 1 Verification without Connection to Management System
Verification Activity 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
