The "TMP-9701" is a measuring instrument used for the maintenance and fault analysis of ISDN lines in communication equipment. It can analyze circuit-switched procedures for up to 8 lines in both BRI and PRI, and it is capable of long-term recording of voice signal packets. The call recording function can record up to 184 channels for more than 2 months. Additionally, the use of an LCD display and touch panel allows for easy operation in setting measurements and analyzing measurement data. 【Features】 ■ Up to 8 BRI or PRI lines can be connected and measured simultaneously. ■ Each of the 8 lines can be selected as BRI/PRI. ■ The call recording function can record up to 184 channels for more than 2 months (when using 8 PRI lines). ■ Recorded data is separated into Lch./Rch. for transmission/reception, allowing for effective detailed analysis of voice signals. *For more details, please refer to the PDF document or feel free to contact us.
