RST Universal Voice Grade (R-UVG)
Remote Subscriber Terminal (RST) Universal Voice Grade (R-UVG) plug-in card provides six individually provisionable ground start or loop start circuits and supports reverse battery signaling for applications such as PBX off-premises lines. The R-UVG is the constant current loop feed counterpart to the L-UVG card, which installs in the Local Exchange
Terminal (LET). The R-UVG is direct-mapped (non-concentrated) to the corresponding L-UVG card and establishes six dedicated circuits.
Features
- Automatic or provisionable transmission gain (0.1 dB steps)
- Ground Start and Loop start and Reverse battery signaling
- Forward disconnect
- Firebar continuous ringing
- Private Line Automatic Ringdown (PLAR) hotline service
- On-hook transmission
- Remote test access to metallic tip and ring
- Call Message Waiting Indicator (CMWI)
Features
Easy Provisioning
From CUI or Â鶹¹û¶³´«Ã½ Panorama EMS the R-UVG can also be provisioned to support Å“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).
Testing Capabilities
The R-UVG card also supports multiple loop testing systems including Mechanized Loop Testing (MLT).
