2 E1 Digital Trunk Board

The 2 E1 digital trunk voice processing board adopts the latest DSP, and one board provides 2 E1 digital trunk interfaces, which can process 60 voice channels, and 2 SS7 (MTP, TUP, ISUP, and SCCP) links. The powerful DSP technology can effectively reduce the host loads, and the firmware can be updated by the network. It ensures that the high-density and large application system runs stably, which is convenient to construct multi-function, nice cost performance, and upgradable application system to protect customer investment maximally.
