telephone service.
Handles DMT signals only in both direct connect and splitterless deployments
Requires that its DMT modem ports be connected directly to a CO facility main distribution frame
(MDF) when used in splitterless CPE installations
Requires that its DMT modem ports be connected to an ADC Telecommunications, Inc. central
office high-density 240-port chassis (DMT/ISDN) signal splitter or other Cisco qualified
DMT/ISDN signal splitter when used in CPE ISDN installations
