●the main called information receiving function. ●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. industry application: (1) mobile network data collection;
(2) large-capacity e1 relay recording system. digital relay recording card application network diagram: |
