A communications network (200) and method (500) is provided for framing poin t- to-point frame structures (215, 300, 402) to minimize the overhead that consumes the bandwidth of a radio air interface (216) located between a mobi le station (206) and a packet switched network (202). More specifically, the mobile terminal (206) utilizes a serial interface (222) and point-to-point protocol to connect to a data terminal (220), and a communication protocol a nd air interface (216) to connect to the packet switched network (202). The mobile terminal (206) inserts a first predetermined set of fields (312) (overhead) onto a first frame structure (300) (data) received from the packe t switched network (202), and then forwards the inserted first frame structure (302) (data and overhead) to the data terminal equipment (220). In addition, the mobile terminal (206) removes a second predetermined set of fields (406) (overhead) from a second frame structure (400) (data and overhead) received from the data terminal (220), and then forwards the stripped second frame structure (402) (data) to the packet switched network (202). Wherein the consumption of the bandwidth is minimized when the frame structures (215, 30 0, 402) depending on the direction of travel are either stripped off or inserte d with overhead fields (312, 406) such that mostly data is transmitted between the mobile terminal (206) and the packet switched network (202).
