(7302ISAM (IntelligentServicesAccessMultiplexer, intelligent service access multiplexer) is a DSLAM completely based on IP core, which continues the attributes and advantages of 7300/7301ASAMXD (extremely high density) equipment and DSL software and hardware platforms. The hardware structure of ISAM adopts the same hardware structure as that of ASAMXD. A single chassis supports 48-line ADSL/ADSL2/ADSL2 user boards, and has 16 LT user board slots and 2 NT main control board slots (NT board supports active and standby office mode ), using an independent splitter frame, the splitter can be built-in or external. A single rack can support 768 line users under the condition that the user board chassis and the splitter chassis are installed at the same time. A single rack can support up to 1536 line users without installing the splitter frame and only installing the user board frame.)
