ISDN Terminal Adapter Data-Only	5

This type of digital data station includes only the DTE and ISDN terminal adapter. The ISDN terminal adapter connects the DTE to the system through an MLX extension jack on the control unit (see Figure 5–5). Since the configuration does not include an MLX telephone, if a 7500B data module is used as the ISDN terminal adapter, a 440A4 terminating resistor adapter is required.
