Zhejiang Medou Communication Technology Co., Ltd.

● When the connection is used, a single card can provide up to 16 digital trunks. When using monitoring, the single card provides 8 pairs of (two-way monitoring) digital trunks.

● Without the DSP module, it supports up to 16E1 SS7, ISDN, SS1 acquisition, supports 480 channels of FSK communication, for data transmission, supports a full range of different kernel LINUX, WIN series operating systems, multi-card cascade. ● With different number of DSP modules, different channels can be used for voice recording and playback operations, high-speed signaling acquisition and output, power-off control, SMS interception, voice recording output, multi-party conference calls, etc. Each E1 time slot can be used. Configured into different signaling formats, voice channels, and data channels. ● SS7 supports 64k and 2M high-speed links and supports 1 to 31 arbitrary signaling time slots. SS7 supports protocols such as MTP3, TUP, ISUP, and TACP. It supports 14-bit and 24-bit point codes, and can be used in combination with multiple cards and multiple cards, and can complete the processing of multiple No. 7 signaling links. ● Support multi-link working mode to meet the needs of users' pure data services. Can support SIGTRAN protocol, provide M3UA development interface. ● ISDN supports protocols such as PRI-ISDN clusters and Q.SIG. ● SS1 supports CAS, LINE SIED, CLEARCHANNEL and other protocols. ● The backplane can be configured with an IP module that supports up to 256 lines of SIP voice access processing capability. ● Maximum support for 496 channels of 64K HDLC reception. ● Supports 480-line conference calls and supports hybrid access of SIP and relay conferences. Each channel has its own independent conference resource and can be configured to any voice channel. ● The backplane can accommodate up to four DB1200 modules for high-speed signaling access. ● Supports 32/64-channel soft fax resources. ● Support standard H.100 bus, which can be interconnected with third-party devices that support this bus.
