Tellabs® 1000 Multiservice Access Platform (MSAP)
LET Universal Voice Grade (L-UVG) Plug-in Card
Overview
L-UVG
The Tellabs® 1000 Multiservice Access Platform (MSAP) 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.
FAIL
BUSY
The L-UVG card is direct-mapped (nonconcentrated) 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 the provisionable full time.
Forward disconnect is supported in the POTS mode. The card
also supports precision gain adjustment in 0.1 dB 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).
