Technical Specifications

The MultiModemZDX modem meets the following specifications:

Trade Name	MultiModemZDXTM
Model Number	MT5656ZDX
Server-to-Client Data Rates	V.90 speeds when accessing a V.90 or V.92 server (actual speed
	depends on server capabilities and line conditions) *Though these
	modems are capable of 56K bps download performance, line
	impairments, public telephone infrastructure and other external
	technological factors currently prevent maximum 56K bps
	connections.
Client-to-Server Data Rates	Up to 50Kbps when accessing a V.92 server (actual speed depends
	on server capabilities and line conditions); otherwise, the same as
	client-to-client data lines.
