Introduction
The 8xDMT is designed for use in one of the following system configurations:
• With a POTS splitter chassis—Provisions one modem directly and is physically connected to one
specific subscriber line through the POTS splitter chassis.
• Without a POTS splitter chassis—Provisions one modem directly and is physically connected to one
specific subscriber line through the main distribution frame (MDF) connections.
The 8xDMT
• Supports eight ADSL modem connections.
• Converts ADSL modulation from the line into digital data streams to and from the NI-2 card.
• Negotiates the line rate with the customer premises equipment (CPE) when it trains and bases the
rate on line quality and distance.
If provisioned, the 8xDMT rate adapts to the maximum bit rate negotiable on the line. The maximum bit
rate settings are provisioned in the management software.
Table 1 details the total available ADSL modem connections for each chassis.
Note For line card intermixing information, refer to the appropriate hardware installation guide for
