Alcatel-Lucent 7342 ISAM FTTU - Manual (Page 7)

7 Alcatel-Lucent 7342 ISAM FTTU
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
differ ent 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 Low Profile
Multiple Dwelling/Tenant ONTs
for up to 12 living units or small
businesses (LP-MDU-ONTs).
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 forward ed to a
broadband service aggregator (BSA)

Figure 3. Alcatel-Lucent 7342 ISAM FTTU in a Network
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.
