KE3700 xDSL MultiTest is the perfect tool for service technicians from network operators and for ICT specialists.

The innovative and modular platform of KE3700 can be configured according to the requirements of the user. Numerous hardware and software options allow the user to combine the functions of several test devices in one housing – even at a later date. This guarantees a high degree of investment and future security and a high degree of flexibility.

The multifunctional KE3700 is ideally suited for testing tasks during installation and interference suppression of the broadband services ADSL1/2/2+ / SHDSL / VDSL2, VDSL2 Vectoring as well as for the latest standards Super Vectoring (VDSL 35b) and xDSL autodetect starts at the push of a button and automates the synchronization process. Thanks to gigabit interfaces for copper and fibre optics, the KE3700 can also be used to carry out measurements in broadband networks based on FTTB and FTTH and also in the local customer network (LAN). Automatic and configurable speed tests enable the user to determine the maximum available bandwith.

Disturbances of the service, caused for example by faults in the cabling, defective customer equipment and external frequency interferers, can be reliably isolated.
Measured values can be viewed in tabular form and selected parameters can also be viewed graphically over the entire duration of the measurement. The colour display of the KE3700 is protected by safety glass and can even be read in sunlight.

Thanks to the at-a-glance display and intuitive operation, without time-consuming menu changes, efficient work is guaranteed. The multitasking function allows the user to run several tests in parallel.

In addition to extensive test functions for the common telephony services ISDN and POTS (analogue), KE3700 is able to test VoIP telephony and evaluate voice quality based on relevant parameters. KE3700 supports standard SIP, SIP trunk and enables users to conduct up to 10 calls simultaneously (MultiCalling).
The test function for IPTV services includes a channel scan and a preview image in addition to single and multistream. Extensive parameter statistics allow the technician to make a reliable quality assessment.

New Wi-Fi test functions are available for service testing in 2.4 and 5 GHz networks. Classic function tests, extensive network information, quality parameters incl. automatic good/bad evaluation and a Wi-Fi monitor are part of the range of functions. Furthermore, the KE3700 even enables the testing of triple-play services (Data/VoIP/IPTV) in wireless networks.

The KECT copper test module, which can be integrated in the housing, is used for comprehensive status analysis and detailed fault detection on the telecommunication twisted pair. AC/DC cable multimeter measurements help to determine important line parameters. Precise measurements of line length and fault location can be determined via TDR (Time Domain Reflectometry) and RFL (Resistive Fault Location). In combination with the KE905 Remote electronic line switch, automatable measurement sequences can be carried out. RF measurement functions allow the technician to assess the quality and qualification of the copper twin wire. The KE3700 also provides an insight into the transmission spectrum, which enables the detection of frequency disturbances.
The DMM Digital Multimeter option allows a quick test of the building‘s internal telecommunication lines. Resistance and capacitance values are tested, including determination of the line length and voltage.

Stored measurements in the KE3700 can be recalled for review and viewed in detail. Measurement logs can be transferred directly to a USB stick as a PDF or managed via the included KE-Manager software. The QR code display also allows live measurement results to be transferred to digital order processing systems.
