The in-line modular TAMs are designed to plug straight into the DSLAM, but due the DSLAM construction this is not possible as the module extends outside the cabinet. When space is available within the DSLAM rack an Internal Shelf is utilised to house the XD modules. When no space is available within the rack or corresponding racks then an External Shelf shelf is required. The External shelf is fitted to the top of the rack and the XD Modules inserted.
The DSLAM cable is connected to the DSLAM side of the module and a tie cable, fitted to the other side, is returned to the DSLAM.
Retrofit takes less than an hour, the cables are removed from the Module, the modular TAM replaced and the cables re-connected.
The installation teams will be provided with all the tools required to carry out a retrofit installation.
Partial installations are also possible, adding additional modules as the customer base expands.
Line Capacities are achieved by daisy chaining up to 24576 lines with an ISMC 32ES-EU or 98304 with the ISMC 128ES-EU.
