Some decription of MindSpeed M825xx
1, CSM_ENCAPS protocal :
The CSM_ENCAPS protocol is used to provide a Reliable Data Transfer Mode over the Ethernet, while keeping the protocol as simple as possible.
2, Message Transfer Mechanism:
The API uses a common message format with a specific message transfer mechanism for the PCI/uP and Ethernet control interfaces.
3, Message Operation:
4, Boot Loading:
5, Supervisor:
The Supervisor main function is to create and destroy channels based on commands from the Host. The Supervisor monitors the status of system resources and decides whether to accept or decline a request to create a channel based on the availability of resource requirements for the channel type requested.
6, SPI Bus Feature:
The Mindspeed Comcerto Device IP PBX demo design uses the SPI bus to control the SLIC/SLAC devices.
7, TDM Bus Management Feature:
The Mindspeed Comcerto Device provides four TDM buses that can be configured for a total of 512 timeslots.
A bus that is clocked at 8.192Mhz has 128 physical timeslots from 0-127.
1). TDM_SELECT_BUS_MODE: This command allows the Host to select 1-bus, 2-bus or 4-bus mode of operation.
2). TDM_ENABLE_BUS: it is used to enable one or more TDM buses on the Mindspeed Comcerto Device.
3). SUPVSR_ SET_PCM_LAW: it allows the Host to specify which PCM law (i.e. A-Law or mu-Law) will be used when transmitting (8-bit) PCM samples over a TDM time slot.
4). SUPVSR_SET_TS_MODE:
5). SUPVSR_SETUP_TDM_PARAMS:
8, TDM-to-TDM (TDM Hairpin Loopback) Feature:
9, POS/Utopia Interface:
10, AAL5 Device Level Message Descriptions:
The Mindspeed Comcerto Device handles Voice-stream transport over ATM
networks (VoATM).
11, Ethernet Interface:
12, Mangement Data Input/Output:
13, Dynamic DMAC Configurtaion:
14, Speical Packet handing:
Special Packet Handling is used by the Host to support Network protocols that are not
supported by the Mindspeed Comcerto Device. When the Mindspeed Comcerto
Device receives packets it cannot handle (i.e. unknown protocol from Layer 2 or
Layer 3), some packets (based on specific requirements) will be sent to the Host for
processing.
Special Packet Handling also allows the Host to send packets on the Mindspeed
Comcerto Device Ethernet interface. This requires the Host processor to process the
“special” packets. The Host processor can send packets via a customer supplied
Ethernet interface, or the Host can send the packets through the Mindspeed Comcerto
Device Ethernet interface, using the Special Packet Handling feature.
15, IP Device and Channel Level Message Descriptions:
16, Multiple Source IP Adress Feature:
Comcerto devices support two modes of Source IP Address usage: Single IP Source
Address Mode or Multiple IP Source Address Mode.
Multiple IP Source Address Mode uses one of up to 10 IP Addresses as the Source IP
Address for packets generated by channels on the same device, and each channel can
use any of the 10 possible IP Addresses.

VoIP_VOPENA: Start/Stop VoP Channel Processing (Function Code 0x8000)
The VoIP_VOPENA function code is used to start or stop VoP channel processing in
the Mindspeed Comcerto Device. VoP channel processing is disabled by default.
When channel processing is enabled, the stream of packets from the host will be
decoded into PCM signals on the line, and PCM signals from the line will be encoded
into a stream of packets. The command also activates the DTMF and tone detectors,
so the host may start to receive autonomously generated indication messages after this
command is issued. The encapsulation method used is indicated by a value passed in
the FIFO and the values are described in the following sections.
