E1/T1 Monitor 3.0 provides permanent monitoring of signalling on E1/T1/J1 (2 or 1.5 Mbit/s) lines. It can be connected to the GSM Gb, Abis, A, C, D, E and F links and on 3G Iub, Iucs and Iups links.
E1/T1 Monitor 3.0 decodes layer 1 and layer 2 of the protocol stack, timestamps and then forwards the monitored data to an external server over TCP/IP. The monitored data can be used for real-time billing, fraud detection and network supervision.
Hardware Features
- Dual 48 VDC power inputs.
- Dual 10/100 Mbit/s ethernet, both can use Power over Ethernet (PoE).
- Low power consumption (typical: 6 W).
- No moving parts.
- 19" rack mount, 1U high, 144 mm (6" ) deep.
- 64 E1/T1 receivers, i.e. capable of monitoring both directions of 32 E1/T1/J1 links.
- E1/T1/J1 inputs are compatible with -20 dB and -30 dB protected monitor points (ITU-T G.772) for non-intrusive monitoring and normal, unattenuated E1/T1/J1 signals for connection to a MUX or DXC.

In-band data access
For applications requiring unprocessed access to the data, for instance error analysis or voice quality measurements, the probe can forward the links to an external application without any L2 processing.
In-band signalling (DTMF, CAS MFC R2, SS5) can also be applied to voice timeslots.
