Zhejiang Medou Communication Technology Co., Ltd.

● The single card has 2/4/8/16 high-impedance multiplexed input channels to monitor the uplink and downlink signals of 1/2/4/8 E1 ports. ● Supports three recording modes: incoming one-way recording, outgoing one-way recording, and incoming and outgoing mixed recording. ● Supports automatic gain control (AGC). ● Supports standard or custom DTMF signal/single audio signal detection call/mute detection. ● The card is equipped with a lightning protection circuit that complies with the telecommunications standard to ensure that it is not damaged by lightning strikes. ● A single card supports a maximum of 496 low-speed 64Kbps signaling accesses, supports 16 high-speed 2Mbps signaling accesses, and supports 16 high-speed n*64Kbps signaling accesses. ● It can be configured to collect 64K SS7, 2M SS7, HDLC, and transparent data stream. ● It can collect the direct connection and the collimated link of the SS7 fixed network and the A interface, B interface,

C interface, D interface, E interface, G interface and PSTN of the mobile network all SS7 signaling links in the SC short message center and other interfaces. ● Support China SS7 related protocols: MTP, MTUP, TUP, ISUP, SCCP, TCAP, MAP, BSSMAP, BSSOMAP, DTAP, INAP, CAP. ● Flexible configuration of signaling links and E1. ● Each E1 has an independently adjusted gain amplification and can adjust the signal according to the actual line conditions.
