R

RJ-45. A CAT 5 cable used to connect the Tenor CMS to an Ethernet.

RJ-48. A CAT 5 cable used to connect the Tenor CMS to a Line Circuit or Trunk Circuit.

RADIUS. When using IVR, the RADIUS (Remote Au- thentication Dial-In User Service) is used for authen- ticating and authorizing user access to the VoIP network.

S

SelectNet™. The next generation of TASQ technology; the functionality monitors your data network for jit- ter, latency, and packet loss, and transparently switches customer calls to the PSTN when required.
