T1, 100 Ohms, 16 Port High Impedance
(Hi-Z) Monitoring Patch Panel
(T1, 100 Ohms - Version)


The E1/T1 16 Port Monitoring Patch Panel is primarily designed for applications where E1/T1 circuits are required to be “tapped” for non-intrusive monitoring applications. The E1/T1 Monitoring Patch Panel is simultaneously provides up to 16 high-impedance (Hi-Z) outputs on it's monitoring (MON) port(s) from which, both the transmit (Tx) and the receive (Rx) signals of the patched E1/T1 link can be “tapped non-intrusively” (i.e without disturbing or loading the active E1/T1 link(s) in any manner, and connected to E1/T1 Groomers, Probes or Analysers.

DIP Switch settings

All four DIP switches must be set to OFF position for non-intrusive monitoring applications.

Connecting E1/T1 Main Link


The RJ-45 Connectors Row A and Row B are used for Data IN/Data OUT from/to the Site A and Site B E1/T1 link.

Connecting Hi-Z Output

The RJ-45 Connectors Row MON are used for Hi-Z Data OUT from the E1/T1 link connected on Row A and Row B to E1/T1 Groomers, Probes or Analysers.
