Mediatrix media and signaling gateways are small branch office gateways that connect endpoints in an office serving 200 or fewer subscribers. Because they are ISDN gateways, they support ISDN switching, router function, and a gateway which converts ISDN voice data into Internet Protocol IP data streams or voice over IP, and vice versa.
The Mediatrix gateways support the following:
User-programmable call handling.
CLI, SNMP, Telnet, and TFTP (Trivial File Transfer Protocol) for configuration and management.
RS-232 console port for configuration.
Fax over IP.
The Mediatrix gateways also support encrypted SRTP (Secure Real-Time Transport Protocol) with the MIKEY (Multimedia Internet Keying) Profile 0 key management protocol.
The following table lists and describes the Mediatrix models. The number of users each supports depends entirely on the following:
