The modularity of the Alcatel-Lucent 7330 ISAM FTTN expansion shelf (ES) enables your efficient growth of services and supports up to 192 DSL lines per shelf (as shown in Figure 4). The same shelf, which is used for the host is also used for the ES. The expansion shelves can be collocated with a host shelf at a common site, or remotely located with the host and expansion shelf at separate sites. In either scenario, the Alcatel-Lucent 7330 ISAM FTTN ES uses GigE links to connect to the host shelf.
For flexibility and convenience, the Alcatel-Lucent 7330 ISAM sealed expan- sion modules (SEMs) (Figure 4) are sealed enclosures that can be mounted directly on the outside of a cabinet, on a pole or in a pedestal, or hung on a strand. There are two versions: VDSL and ADSL. The VDSL version has 24 VDSL ports, and the ADSL version has 48 ports. Based on the design of the line terminations of the Alcatel-Lucent 7330 ISAM FTTN host shelf, both versions have features and capabilities that are similar to the line cards on the Alcatel-Lucent 7330 host and expansion shelves (See Figure 2).
