From CUI or Tellabs Panorama EMS the R-UVG can also be provisioned to support “firebar” (continuous) ringing, full time on-hook transmission and Private Line Automatic Ringdown (PLAR) hotline service. The R-UVG
is typically used at the RST. The R-UVG can be installed in the LET to support Direct-Inward-Dial (DID) applications. Each R-UVG circuit can be independently provisioned as a D4 FXS, D4 DPO, TR-8 POTS or TR-8 DID circuit. The R-UVG card provides ring cadence following including ring-ping.
Mutliple Modes of Transmission
Three (3) modes of on-hook transmission are supported: between ring bursts, loop current feed open interval and provisionable full time.
Forward disconnect is supported in POTS mode. The card also supports precision gain adjustment in 0.1 dB steps over a 12.0 dB
range and automatic transmission loss switching with loop length (one step of 3 dB).
