Trunk-based communications monitoring system
The “TerraLine” Global Monitoring System (hereinafter as “System”) is designed for automatically input,
record and process communication sessions from digital trunks with different kind of signaling such
as ITU #5, R1, R1.5, R2, DTMF, R2D, ISDN, EDSS1, SS#7 and A or A-ter interfaces. The System provides
classification of sessions according to signal forms (voice, fax or data) and their storage during predetermined
time together with the session-related information (date, time, duration, calling and called
telephone number, TMSI, IMSI, IMEI, cell’s number etc.). Also System provides an ability to determine a
location of the selected/targeted mobile subscriber while the session is in progress.
“TerraLine Global” system provides:
• Monitoring connection, tapping and translation of digital trunks of E1 and STM1-16;
• Procession of digital trunks with ITU #5, R1, R1.5, R2, DTMF, R2D, ISDN, EDSS1, SS#7 signaling;
• Procession of digital trunks of GSM cellular communications network with A or A-ter interfaces;
• Automated selection of sessions by phone numbers, MSISDN, IMSI, IMEI, Cell ID;
• Demodulation of fax sessions, according to V.27ter, V.29, V.17 and V.34 fax recommendations;
• Procession of MH, MR, MMR, ECM, JBIG, JPEG protocols.
• Demodulation of V.21, V.22, V.22bis, V.26, V.26bis, V.27, V.29, V.32, V.32bis, V.33, V.34, V.90 modem
• Decoding and error correction V.42, V.42bis, V.44, CODEX, MNP 1-5, HDLC, PPP, Slip, UUCP, IP, TCP, UDP,
SMTP, POP3, IMAP, MIME, FTP, Web, X-Y-Z modem and Kermit protocols etc;
• Support of the local database, providing
the storage of phone numbers of interest
and search of information about the
required communication sessions;
• Automated archiving of the recorded
information into external digital media;
• Automated operation of the system according
to pre-set scenario;
• Possibility of the remote access to the
system via LAN, WAN, Dial-up, Leased
