Universal Voice Grade (L-UVG)

SKU: 0110-0095 Category:

The LET Universal Voice Grade (L-UVG) plug-in card is the LET counterpart to the RST Universal Voice Grade (R-UVG) plug-in card. In the default ground start/loop start service mode, the L-UVG card direct-maps to the corresponding R-UVG card and establishes six dedicated circuits, thereby reducing the total number of spans for concentration. Other provisionable service modes provide for timeslot concentration within the Tellabs 1000 transport.

Material Status

Production

  • Automatic or provisionable transmission gain (0.1 dB steps)
  • Ground Start and Loop start and Reverse battery signaling
  • Reverse battery (quiet)
  • Wide ring voltage/frequency detection window
  • Software provisionable 600/900 Ω impedance
  • On-hook transmission
  • Compatible with the following test systems MLT, Teradyne 4TEL and Reltec
  • Call Message Waiting Indicator (CMWI)

Easy Provisioning

From CUI or Tellabs Panorama EMS each L-UVG circuit can be independently provisioned as a D4 FXO, D4 DPT, GR-08 POTS or GR-08 DID circuit. The L-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. The L-UVG is typically used at the LET. The L-UVG can be located at the RST to support Direct Inward Dialing (DID) applications.


Testing Capabilities

The L-UVG card also supports multiple loop testing systems including Mechanized Loop Testing (MLT).
