Tellabs® 1000 Multi-Service Access Series
LET Universal Voice Grade Plug-in Card (L-UVG)
Overview
Features
The Tellabs 1000 Multi-Service Access (MSA) Series Local
Exchange Terminal (LET) Universal Voice Grade (L-UVG) plug-in
card provides six individually provisionable circuits that support
ground start, loop start and reverse battery signaling for applications
such as PBX off-premises lines.
®
The L-UVG card is direct-mapped (non-concentrated) to a corresponding R-UVG card, installed in an Remote Subscriber Terminal
(RST) and provides six dedicated circuits of universal voice grade
services.
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. Three 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 0.1dB steps over a 12.0 dB range. The L-UVG can be located
at the RST to support Direct Inward Dialing (DID) applications.
The L-UVG card also supports multiple loop testing systems
including Mechanized Loop Testing (MLT).
