GSM Analyzer Main Features
Interfaces supported are A (Interface b/w BSC and MSC), A-bis (Interface b/w BSC and BTS), B (Interface b/w the MSC and its associated VLR), C (Interface b/w the HLR and the MSC), D (Interface b/w the HLR and the VLR), E (Interface b/w MSCs), F (Interface b/w MSC and EIR), H (Interface between HLR and AuC), J (Interface b/w the HLR and the gsmSCF).
Supports real-time as well as off-line analysis.
Displays summary, detail, hex-dump, statistics, and call trace views.
Summary View displays MTP2, MTP3 information, GSM Message types, information about various channels used during the call, frequency hopping etc.
Detailed View displays easy to understand decodes of user selected frame.
Decoding of many RR layer non-transparent messages such as “System Information”, “Measurement Result”, “Immediate Assignment” etc.
Statistics view displays statistics based on frame count, byte count, frames/sec, bytes/sec etc for the entire captured data.
Call trace view displays call statistics such as number of active/completed calls, durations of the completed calls, Type of Call (e.g. SMS/Location Update/Authentication/Speech Call), IMSI/TMSI associated with each call.
Hex dump view displays raw HDLC frame data as a hexadecimal and ASCII octet dump .
Real-time filter and search features on various GSM message types
Recorded trace files can be played back using HDLC playback option
Streams can be captured on the selected time slots (contiguous or non-contiguous), sub-channels or full bandwidth. Frames can be transmitted/captured in either, n x 64 kbps, or n x 56 kbps data channels .The variations accommodated in the software are inverted or non-inverted data, and byte reversal or non-reversal.
Simultaneous decoding of multiple GSM Links on the same or separate T1/E1
Exports detailed and summary information to a comma delimited file for subsequent import into a database or spreadsheet.
Remote monitoring capability using GL's Network Surveillance System
Supports interfaces such as A, Abis and Gs for different variants of GSM such as GSM 900, DCS 1800 , PCS 1900MTP2: Q.704, ITU-T Blue Book / ANSI T1.111-1996
