The 7500B Data Module is a terminal adapter primarily intended for connecting

allow the attached DTE and DCE to send and receive data through the digital
network. The 7500B has no voice functions.

wants to connect his DCE and DTE with DTE, DCE, or host processor at another
location using an ISDN network. The 7500B data module cannot be used in a
