24 port modular analog PCI 3.3/5.0V card with 4 Trunk interfaces and HW Echo Can
The Digium Wildcard TDM2400P is a full-sized 32-bit, 33 MHz PCI 2.2 card that supports FXS and FXO interfaces for connecting analog phones and analog phone lines to a PC. With the help of an Asterisk Open Source PBX IP telephone exchange server and a primary PC, the purchase of a Digium Wildcard TDM2400P can provide a telephone exchange for a small office, which will provide all the complex and basic functions of the daily telecommunications equipment for great business.
The Digium Wildcard TDM2400P board takes the place of a bulky and expensive channel concentrator, and the performance of the IP telephony system is even low. If you choose the existing X400M and S400M mezzanines with TDM2400P board, you can achieve a solution that supports a variety of telephone connections. To increase the scale of your solution, simply add additional TDM2400P cards with the necessary sets of interface modules and echo compensation.
Apparently, the skin mezzanine QFXO / QFXS has 4 ports.
Decoding the smart values of TDM sets is available: TDM24 XYB, where “TDM24” means what is Digium Wildcard TDM2400P, “X” means the number of FXS mesonines, “Y” means the number of FXO mezzanines, "B" means that the dialing is without hardware echo compensation. "E" means dialing at the same time with hardware echo compensation.
