￼The Osmocom E1/T1 tap adapter allows you to tap into the communication of an E1/T1 line.
This is useful for tracing/analyzing communications on any type of E1/T1 based interface, such as A-bis, A and core network interfaces in GSM networks, as well as classic ISDN networks.
Two RJ-45 ports are used for passing through your existing E1/T1 line. Using a switch, the pass-through can be configured in straight or cross-over mode.
Two additional RJ-45 sockets are provided for tapping into either of the two pairs (Rx/Tx) of the E1/T1 line.
An additional switch can be used to select between high and low impedance tapping.
All ports are configured in Digium-compatible pin-out, i,e, pairs 1+2 / 4+5
