IP-Based xDSL
MSAP2000’s AAM provides IP-based ADSL2/2+ services.
Each AAM will support 12 ADSL2/2+ interfaces, and can share 100
Mbps bandwidth. When the MSAP2000 uses GbE as its transmission
trunk interface, and will allow 192 ADSL interfaces in one single shelf
share 2000 Mbps of bandwidth for uplink.
