Tellabs 1000 Multi-Service Access Series LET Universal Voice Grade Plug-in Card (L-UVG) Overview
DATA SHEET 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). Six two-wire circuits per unit n Software selectable transmit gain (0.1 dB steps) n Ground start/loop start capability n Reverse battery (quiet) n Wide ring voltage/frequency detection window n Software provisionable 600/900 Ohms impedance n On-hook transmission n Compatible with the following test systems: MLT, Reltec, Teradyne 4TEL n Support for CMWI (Call Message Waiting Indicator) n LED Indicators LEDs on the L-UVG faceplate indicate the following: Green BUSY — one or more L-UVG circuits are busy or are being tested and must not be removed from service nRed FAIL — plug-in card failure nBlinking red FAIL — illegal signaling n See tellabs.com for more information about Tellabs Solutions 2 TELLABS 1000 MULTI-SERVICE ACCESS SERIES LET UNIVERSAL VOICE GRADE PLUG-IN CARD (L-UVG) Specifications MLT/Teradyne DC Signatures Signaling End-to-end signaling delay (normal and reverse battery): < 50 msec n On-hook: n – Pulse distortion (normal, reverse, pw > 50 msec): < 15 msec – Ring detection: < 100 msec n AC ringing load (20 Hz): 4 kOhms ± 10 % – Ring detector sensitivity: 40 Vrms 17 to 55 Hz – Nominal DC input resistance: 800 Ohms n n n n Tip to ring: 50 kOhms Environmental Operating Temperature n -40° F to +149° F (-40° C to +65° C) Tip to ground, ring to ground: 430 kOhms n n Nominal DC input resistance in DID mode: 250 Ohms n Ring ground resistance: 600 Ohms n Tip to ring: 43 kOhms Tip to ground, ring to ground: 430 kOhms Off-hook: n DLC Test Resources in Use Signatures n Tip to ground, ring to ground: 167 kOhms Humidity: 5–95% non-condensing n Average power consumption: 1.0 W n Tip to ring: 900 Ohms Off-hook, ring grounded: Tip to ground, ring to ground: 430 kOhms – Width: 0.563 in (1.429 cm) n Depth: 10.5 in (26.67 cm) Tip to ring: 900 kOhms – Dimensions n Height: 5.125 in (13.018 cm) n Maximum CO wiring resistance: 200 Ohms n Weight n 0.5 lbs (0.23 kg) Reltec DC Signatures Audio On-hook: n Companding: μ-Law – VF input impedance (provisionable): 600/900 Ohms – n Tip to ground, ring to ground: 430 kOhms n Nominal net loss (referenced 2-wire 600 Ohms): 0 ± 0.4dB n Tip to ring: 50 kOhms GR-1089-CORE n Off-hook: n Maximum VF overload level: + 5.0 dBm Tip to ground, ring to ground: 430 kOhms – n Longitudinal balance: > 58 dB (400 Hz to 3.4 kHz) – Two-wire return loss: ERL > 18 dB, SRL > 10 dB – n Tip to ring: 835 Ohms Off-hook, ring grounded: n n Transmit gain adjustment: 3 dB to + 9dB n Receive gain adjustment: 9 dB to + 3dB – Tip to ground, ring to ground: 430 kOhms Tip to ring: 835 kOhms n Compliance nR-TSY-000057 TR-TSY 000303 n Next Step: Visit www.tellabs.com to learn more about how Tellabs makes it easy for carriers to offer new higher-speed services.
