VMS modems are soft and do not rely on hardware which may become obsolete. Several of the largest global telco’s have transitioned from legacy analog- based RAS solutions, to the VMS platform, surpassing analog-based connections efficiency with the soft modems. VMS is available for both Commercial and Federal Government applications with CDI providing a turnkey solutions including professional services for system tuning. The VMS will seamlessly integrate with our Out of Band Management system for PSTN, LTE, or Internet OOB. The IP RAS supports the follow modem protocols and can be scaled from One (1) channel, up to hundreds (100’s) of soft modems. The VOIP server operates on the principals of Voice over IP (VoIP) technologies. It is required that the provider supports G.711 μ-law or A-law. It is also required, for V.32 speeds and above, that the provider either does not perform echo cancelation or that the echo cancellers are properly disabled when modem tones are detected.
