Corelatus develops a range of 19" rack-mounted products to connect to E1/T1 and SDH/SONET telecommuncation links. All products are controlled over ethernet. Our customers are system builders who add their own application software on a server and market the complete package to telecom operators.
Corelatus products are all designed according to a philosophy of physical, electrical and functional isolation. Our products are physically and electrically isolated by being inside their own chassis with all IO protected. The functional isolation comes from a narrow, well-defined control interface with a clear separation of responsibilities.
The E1/T1 Monitor 3.0 provides low cost monitoring of 3G Iub, GSM Abis and GSM Gb links.
E1/T1 Monitor 3.0 has 64 E1/T1 receivers, so it can connect to both directions of 32 E1/T1 links. It decodes LAPD and ATM signalling and forwards it to an external server over TCP/IP.
The SDH Monitor 3.0 extracts signalling and voice from E1/T1 streams carried on SDH and SONET links in fixed and mobile telephone networks.
SDH Monitor 3.0 connects to 155Mbit/s STM-1/OC-3 links, extracts a subset of the the E1/T1 streams inside them, decodes layer 1 and layer 2 of the protocol stack and then forwards the monitored data to an external server over TCP/IP.
The E1/T1 Monitor 2.1 connects to E1/T1 lines the same as the E1/T1 Monitor 3.0, but provides a wider range of protocols. 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 2.1 has 16, 32 or 48 E1/T1 receivers in a 1U chassis, so it can connect to both directions of 8, 16 or 24 E1/T1 links.
The E1/T1 Messenger 2.1 terminates 8, 16 or 24 E1/T1 links, provides a non-blocking timeslot switch, handles ISDN LAPD signalling, records voice and signalling, detects DTMF tones and plays back voice and tones.
E1/T1 Messenger 2.1 uses the same hardware as E1/T1 Monitor 2.1.
