●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. typical application: (1) large-scale enterprise call centers;
(2) exchange call center post ivr function;
(3) voice gateways and signaling gateways;
(4) color value, color ring tones and other voice value-added services;
(5) data acquisition, voice monitoring system;
(6) conference calls, multi-party communications;
(7) add automatic equipment monitoring business. digital trunk voice card application topology: |
