The CRU995 module was designed as an efficient, less expensive remote IP/4 wire E&M interface, for a maximum of 4 transmitters, receivers and/or transmitters-receivers. The CRU995 module allows users to use E&M transmitters/receivers in VOIP networks.

The CRU995 module support the ATC ED137 IP/SIP standard. This makes the CRU995 very suitable to use in ED137 migration procedures / processes on airports. Existing analogue transmitters and receivers can connect to ED-137 products. Or ED-137 transmitters and receivers can be connected with existing Communication Systems via the CRU995.
