Recording Server CarpeStar DTP800

  • 1U height, standard rack design
  • support bidirectional recording for 1~8*E1/T1 interface
  • support the global protocols with high interoperability
  • support DSP-based compression coding format
  • web-based recording system management software
  • support recording data storage, query and real-time monitoring

Support multiple protocols and recording modes

DTP800 supports 8*E1/T1 ports at maximum, a range of protocols such as SS1, SS7 (Tup, ISUP), ISDN signaling call status analysis and voice signal analysis, and can be configured for inbounding recording, outbound recording, and mixed in/outbound ones.

Support multiple speech coding formats

DTP800 supports DSP-based a-law (g. 711), µ-law, IMA-ADPCM, GSM, MP3 and G. 729A format coding, and software processing -linear PCM, VOX format Codecs. It can adapt to any recording environment in the world for short time to market.

Adopt hi-impedance multiplexing mode

DTP800 supports high impedance, and does not affect the normal operation of the system. And DTP800 has a strong signal adaptive ability, and can tap into line at any point to monitor call conversation.
