sonet chipset evm user guide 3/23/2001 4:42 pm mindspeed technologies build it first 7 1 introduction the sonet evaluation module (sonet evm) consists of two subsystems. the first subsystem consists of an ibm-compatible pc, which is supplied by mindspeed technologies, containing the sonet evaluation module board. this ?host pc? and its application software run on vxworks, a real-time operating system. the second subsystem consists of the sonet evm gui software running on a windows-based pc, which the user must supply. this ?host pc? provides the user an interface to the ?target pc? through the sonet evm gui software. communication between the two subsystems is through ethernet. socket-based messages originating from the sonet evm gui software residing on the host pc are processed by the vxworks application residing on the target pc. the target pc responses to the host pc?s messages, or requests, by sending back request status and requested information, if any. the sonet evaluation module platform is illustrated in the figure below. high-level details of the software architectures are shown in figure 2. figure 1: sonet evaluation module platform ethernet windows-based "host pc" running sonet evm gui software vxworks "target pc" with evm board user socket-based messages socket-based messages as shown in figure 2, the sonet evm gui software consists of three software layers. the highest layer is the graphical user interface. the gui allows the user to execute device- driver commands and operate the evm at a higher level of abstraction, or without the need to know all the details of the device drivers. messages of the chosen operations or commands are passed down to the second layer for processing. the second layer consists of software modules, whose jobs are to service the messages from the gui. messages from the gui are translated into specific socket-based messages to be sent to the target pc. in most cases, these socket-based messages are one-to-one mapping to the device driver functions residing on the target (vxworks) pc. as such, each device, or chip, on the sonet evm board has a ?control? module that is dedicated to translating, forming, and sending messages from the gui on the windows-based pc to the vxworks application on the target pc, and vice versa. the lowest layer is the comm control, who is responsible for opening and closing tcp/ip sockets, and sending and receiving message across the communication port. on the target (vxworks) pc, the evm message manager is the first to receive messages from the host (windows) pc. it deciphers received messages and processes them according to the request. as shown in figure 2, the evm message manager calls on the corresponding device driver functions directly to perform the requested actions from the sonet evm gui software. as a side note, the device drivers are fully functional drivers. as aforementioned, the second layer of the sonet evm gui software, or the individual control modules, exposes the device driver interfaces. the full sonet gui evm software will allow the user to directly access these driver entry points. figure 2 also shows the different levels of abstraction that each device driver has. once the requests are processed, their status and requested information, if any, are passed upstream from the device driver, to the evm message manager, through the
