Figure 3 illustrates the elements of a complete Alcatel-Lucent 7342 ISAM FTTU end-to-end solution. The solution includes a packet optical line terminal (P-OLT), located in the CO, that terminates PON interfaces connected to many outlying ONTs. The Alcatel-Lucent FTTU solution includes four different types of ONTs: Indoor ONTs (ONT I-Series) for single family homes; Outdoor ONTs (ONT O-Series) for single family homes and Small Office Home Offices (SOHOs); Business ONTs (ONT B-Series); and MDU/FTTB ONTs for up to 24 living units.
The Alcatel-Lucent 7342 ISAM FTTU solution supports longer reach from the CO to the subscriber — up to 20 kilometers (12.4 miles). Each fiber terminated at the P-OLT in the CO can be split using optical splitters, which enables the 7342
to serve up to 64 ONTs located at outlying subscriber sites. The Alcatel-Lucent 7342 FTTU performs service differentiation and traffic flow prioritization in the ONT and P-OLT. The solution grooms voice traffic and forwards it to the PSTN voice gateway — the GenBand G6 using GigE interfaces. Data traffic is groomed and forwarded to a broadband service aggregator (BSA) using multiple GigE and 10 GigE interfaces. Traffic flow prioritization
is performed at all interfaces using up to 8 queues for different service types. Traffic flow grooming is per- formed by using per service or per subscriber virtual LANs (VLANs) in the Alcatel-Lucent 7342 ISAM FTTU and virtual private LAN service (VPLS) instances in the BSA. The VPLS instances are terminated at the BSR, which is connected to the IP routed network.
