Alcatel-Lucent 7342 ISAM FTTU ONT R04.05.06 July 2008 4-5
3FE 51892 AAAA TCZZA Edition 01 ONT Product Information Manual
SLID entry via Ethernet port
The SLID can be entered with a laptop connected to an Ethernet port on the ONT.
This method is only supported on ONTs that have Ethernet connections.
SLID entry via first POTS port
The SLID can be entered with a buttset connected to the first POTS port on an ONT
supporting this SLID entry method.
4.4 NTP server authentication
ONTs authenticate NTP servers using a provisionable security key before
communicating with NTP servers to derive accurate time settings. If the P-OLT is
used to derive time settings, communication is secured using SSHv2. See the
7342 ISAM FTTU Operations and Maintenance Procedures Guide using TL1 and
CLI for more information.
4.5 Physical ONT security
Physical ONT security is provided to limit unauthorized access to remote or outdoor
units.
Tamper-resistant seals and bolts are used to secure the TELCO access cover to the
ONT and to prevent easy access to the enclosure. Specialized security wrenches are
required to open the pin-in Allen-type tamper-resistant screws.
Certain models of indoor ONTs cannot be opened.
4.6 Rogue ONT defence
Fault or error conditions on a single ONT may disrupt the PON for other ONTs on
the same PON. Figure 4-2 shows some possible failure conditions.
