chain + * of struct dsp_conf_member. + * + * After a party is added, the conference is checked for hardware capability. + * Also if a party is removed, the conference is checked again. + * + * There are 3 different solutions: -1 = software, 0 = hardware-crossconnect + * 1-n = hardware-conference. The n will give the conference number. + * + * Depending on the change after removal or insertion of a party, hardware + * commands are given. + * + * The current solution is stored within the struct dsp_conf entry. + */ + +/* + * HOW THE CMX WORKS: + * + * There are 3 types of interaction: One member is alone, in this case only + * data flow from upper to lower layer is done. + * Two members will also exchange their data so they are crossconnected. + * Three or more members will be added in a conference and will hear each + * other but will not receive their own speech (echo) if not enabled. + * + * Features of CMX are: + * - Crossconnecting or even conference, if more than two members are together. + * - Force mixing of transmit data with other crossconnect/conference members. + * - Echo generation to benchmark the delay of audio processing. + * - Use hardware to minimize cpu load, disable FIFO load and minimize delay. + * - Dejittering and clock generation. + * + * There are 2 buffers: + * + * + * RX-Buffer + * R W + * | | + * ----------------+-------------+------------------- + * + * The rx-buffer is a ring buffer used to store the received data for each + * individual member. This is only the case if data needs to be dejittered + * or in case of a conference where different clocks require reclocking. + * The transmit-clock (R) will read the buffer. + * If the clock overruns the write-pointer, we will have a buffer underrun. + * If the write pointer always has a certain distance from the transmit- + * clock, we will have a delay. The delay will dynamically be increased and + * reduced. + * + * + * TX-Buffer + * R W + * | | + * -----------------+--------+----------------------- + * + * The tx-buffer is a ring buffer to queue the transmit data from user space + * until it will be mixed or sent. There are two pointers, R and W. If the write + * pointer W would reach or overrun R, the buffer would overrun. In this case + * (some) data is dropped so that it will not overrun. + * Additionally a dynamic dejittering can be enabled. this allows data from + * user space that have jitter and different clock source. + * + * + * Clock: + * + * A Clock is not required, if the data source has exactly one clock. In this + * case the data source is forwarded to the destination. + * + * A Clock is required, because the data source + * - has multiple clocks. + * - has no usable clock due to jitter or packet loss (VoIP). + * In this case the system's clock is used. The clock resolution depends on + * the jiffie resolution. + * + * If a member joins a conference: + * + * - If a member joins, its rx_buff is set to silence and change read pointer + * to transmit clock. + * + * The procedure of received data from card is explained in cmx_receive. + * The procedure of received data from user space is explained in cmx_transmit. + * The procedure of transmit data to card is cmx_send. + * + * + * Interaction with other features: + * + * DTMF: + * DTMF decoding is done before the data is crossconnected. + * + * Volume change: + * Changing rx-volume is done before the data is crossconnected. The tx-volume + * must be changed whenever data is transmitted to the card by the cmx. + * + * Tones: + * If a tone is enabled, it will be processed whenever data is transmitted to + * the card. It will replace the tx-data from the user space. + * If tones are generated by hardware, this conference member is removed for + * this time. + * + * Disable rx-data: + * If cmx is realized in hardware, rx data will be disabled if requested by + * the upper layer. If dtmf decoding is done by software and enabled, rx data + * will not be diabled but blocked to the upper layer. + * + * HFC conference engine: + * If it is possible to realize all features using hardware, hardware will be + * used if not forbidden by control command. Disabling rx-data provides + * absolutely traffic free audio processing.

If software is used to do the + * process, it is actually the real data flow. If hardware is used, data + * may not flow, but hardware commands to the card, to provide the data flow + * as shown. + * + * NOTE: The channel must be activated in order to make dsp work, even if + * no data flow to the upper layer is intended. Activation can be done + * after and before controlling the setting using PH_CONTROL requests. + * + * DTMF: Will be detected by hardware if possible. It is done before CMX + * processing. + * + * Tones: Will be generated via software if endless looped audio fifos are + * not supported by hardware. Tones will override all data from CMX. + * It is not required to join a conference to use tones at any time. + * + * CMX: Is transparent when not used. When it is used, it will do + * crossconnections and conferences via software if not possible through + * hardware. If hardware capability is available, hardware is used. + * + * Echo: Is generated by CMX and is used to check performane of hard and + * software CMX. + * + * The CMX has special functions for conferences with one, two and more + * members. It will allow different types of data flow. Receive and transmit + * data to/form upper layer may be swithed on/off individually without loosing + * features of CMX, Tones and DTMF. + * + * Echo Cancellation: Sometimes we like to cancel echo from the interface. + * Note that a VoIP call may not have echo caused by the IP phone. The echo + * is generated by the telephone line connected to it. Because the delay + * is high, it becomes an echo. RESULT: Echo Cachelation is required if + * both echo AND delay is applied to an interface. + * Remember that software CMX always generates a more or less delay. + * + * If all used features can be realized in hardware, and if transmit and/or + * receive data ist disabled, the card may not send/receive any data at all. + * Not receiving is usefull if only announcements are played. Not sending is + * usefull if an answering machine records audio. Not sending and receiving is + * usefull during most states of the call. If supported by hardware, tones + * will be played without cpu load. Small PBXs and NT-Mode applications will + * not need expensive hardware when processing calls. + * + * + * LOCKING: + * + * When data is received from upper or lower layer (card), the complete dsp + * module is locked by a global lock. This lock MUST lock irq, because it + * must lock timer events by DSP poll timer. + * When data is ready to be transmitted down, the data is queued and sent + * outside lock and timer event. + * PH_CONTROL must not change any settings, join or split conference members + * during process of data. + * + * HDLC: + * + * It works quite the same as transparent, except that HDLC data is forwarded + * to all other conference members if no hardware bridging is possible. + * Send data will be writte to sendq. Sendq will be sent if confirm is received. + * Conference cannot join, if one member is not hdlc. + * + */ + +#include +#include +#include +#include +#include +#include "core.h" +#include "dsp.h" + +const char *mISDN_dsp_revision = "2.0";

If the remote side changes its IP +the new IP is used for all transmitted packets until it changes again. + + +On Demand: + +If the ondemand parameter is given, the remote IP is set to 0 on timeout. +This will stop keepalive traffic to remote. If the remote is online again, +traffic will continue to the remote address. This is usefull for road warriors. +This feature only works with ID set, otherwhise it is highly unsecure. + + +Socket and Thread +----------------- + +The complete socket opening and closing is done by a thread. +When the thread opened a socket, the hc->socket descriptor is set. Whenever a +packet shall be sent to the socket, the hc->socket must be checked wheter not +NULL. To prevent change in socket descriptor, the hc->socket_lock must be used. +To change the socket, a recall of l1oip_socket_open() will safely kill the +socket process and create a new one. + +*/ + +#define L1OIP_VERSION 0 /* 0...3 */ + +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include "core.h" +#include "l1oip.h" + +static const char *l1oip_revision = "2.00";
