The Quad RS-232 Module is intended for use in the Adtran Total Access 1500 channel bank. The channel unit provides for up to four RS232 Data Communications Equipment (DCE) interfaces from a single 56/64 kbps Digital Data Service (DDS) Circuit. One communications link is shared by up to four Data Termination Equipment (DTE) devices by enabling each DTE to use the path exclusively at regular intervals. Each of the four DTE devices is allowed a portion of the dedicated circuit, not exceeding the allowable bandwidth of 60 kbps.
