SDH Monitor 3.0

The SDH Monitor 3.0 extracts signalling and voice from E1/T1 streams carried on SDH/SONET links in fixed and mobile telephone networks. The probes connect to 155Mbit/s STM-1/OC-3 links, extract a subset of the the E1/T1 links inside them, decode layer 1 and layer 2 of the protocol stack and then forward the monitored data to an external server over TCP/IP.

SDH Monitor 3.0

Hardware Features

  • Two or six SFP sockets in 1U. One chassis can monitor both directions of one or three SDH/SONET links.
  • Dual 48VDC power inputs
  • Dual 10/100Mbit/s ethernet, both can use Power over Ethernet (PoE)
  • Low power consumption (typical: 6 W per sub-module or 18 W per chassis)
  • No moving parts
  • 19" rack mount, 1U high, either one or three sub-modules per chassis

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.
