ISDN Lines Analyzer
TMP-9701
This instrument is used to maintain ISDN lines in communication equipment and analyze their failures.
It can analyze a maximum of eight lines, including the line switching procedures of BRI and PRI lines, as well as record audio signal packets in such lines for an extended period.
Equipment Category
Measuring instruments for digital communication
Power supply
AC adaptor
A maximum of eight lines including BRI and PRI lines can be connected to this analyzer and measured simultaneously.
The eight lines can be individually selected from BRI or PRI lines.
Its call recording function allows the recording of up to 184 channels for over two months.
(when eight PRI lines are recorded)
Recording of transmission and reception is performed separately in L-ch. and R-ch., respectively, allowing its effective use for the detailed analyses of audio signals.
Measured data is stored in the built-in memory and can be converted into a format that can be edited with PCs, etc.
LAN ports are incorporated for interfacing with PCs, enabling the collection of measured data in addition to the remote setting and monitoring of measurement conditions.

| Data storage | Capacity | Continuously stored for 2 months (traffic intensity: 6 HCS) | |
| Contents | D channel: signals on the D channel B channel: audio signals, data (packet signals) Audio signals are processed into an audio file (WAV format) when they are transferred to a console PC for storage. In the file, upstream signals (TE to NT) in the left channel and downstream signals (NT to TE) in the right channel are separated in a similar way to stereo recording. |
