Resumen del manual


Slow Blinking (Blinking 1 time per second) Synchronized with an SNR margin Green greater than the user defined SNR Margin Alarm Threshold and the pulse attenuation is greater than the user defined Loop Attenuation Alarm Threshold Solid Yellow Synchronized with an SNR margin greater than 0 dB but less than the user defined SNR Margin Alarm Threshold . Slow Blinking Synchronized with an SNR margin greater than 0 dB but less than the Yellow user defined SNR Margin Alarm Threshold and the pulse attenuation is greater than the user defined Loop Attenuation Alarm Threshold Solid Red Synchronized with an SNR margin of 0 dB . Slow Blinking (Blinking 1 time per second) Synchronized with an SNR margin of 0 dB Red and the pulse attenuation is greater than the user defined Loop Attenuation Alarm Threshold LP1/LP2 CUST Off No span power present Solid Green Synchronized with an SNR margin greater than the user defined SNR Margin Alarm Threshold . Fast Blinking (Blinking 3 times per second) Attempting to synchronize with the Green H4TU-R . Slow Blinking (Blinking 1 time per second) Synchronized with an SNR margin Green greater than the user defined SNR Margin Alarm Threshold and the pulse attenuation is greater than the user defined Loop Attenuation Alarm Threshold Solid Yellow Synchronized with an SNR margin greater than 0 dB but less than the user defined SNR Margin Alarm Threshold . Slow Blinking Synchronized with an SNR margin greater than 0 dB but less than the Yellow user defined SNR Margin Alarm Threshold and the pulse attenuation is greater than the user defined Loop Attenuation Alarm Threshold Solid Red Synchronized with an SNR margin of 0 dB . Slow Blinking (Blinking 1 time per second) Synchronized with an SNR margin of 0 dB Red and the pulse attenuation is greater than the user defined Loop Attenuation Alarm Threshold LL/RL Green Indicates a loopback at the H4R toward the H4TU-R is active Yellow Indicates a loopback at the H4R toward the H4TU-C is active .

TURNUP & TROUBLESHOOTING GUIDE PRICING AND AVAILABILITY 800.827.0807 TECHNICAL SUPPORT 800.726.8663 RETURN FOR REPAIR 256.963.8722 61221445L1-22B TURNUP & TROUBLESHOOTING GUIDE PRICING AND AVAILABILITY 800.827.0807 TECHNICAL SUPPORT 800.726.8663 RETURN FOR REPAIR 256.963.8722 61221445L1-22B H4TU-C VMDF H4R1 H4R2 H4TU-R FOR OPTIMUM OPERATION HDSL4 LOOP SPECIFICATIONS NOTE: The H4TU-Cs P/N 1221401L6, 1221403L6, 1221404L6 support only one H4R in the HDSL4 circuit. ¦ HDSL4 circuit containing no H4Rs will reach up to 16 kft on the local loop (24 AWG) ¦ HDSL4 circuit containing one H4R will reach up to 16 kft on the first segment and 15 kft on the second segment (24 AWG). First Segment Second Segment Third Segment ¦ HDSL4 circuit containing two H4Rs will reach to 13.5 kft on the first segment, 14 kft on the second segment, and 15 kft on the third segment (24 AWG). * NOTE: Refer to the H4TU-C or H4TU-R Installation and Maintenance Practice, Section HDSL4, Deployment Guidelines, for other loop parameters including Insertion Loss, Pulse Attenuation, and Resistance Budgets for span powering *This is one example of a circuit with 2 H4Rs. Other loop length configurations are possible in compliance with loop resistance restraints. Refer to the H4R Installation and Maintenance Practice, Section HDSL4 Deployment Guidelines, for other loop parameters including Insertion Loss, Pulse Attenuation, and Resistance Budgets for span powering. UNIT RESISTANCE Measurements are with no power applied The H4R Tip-to-Ring resistance is approximately 6 . for each pair. COMPLIANCE This product complies with UL 60950, third edition. It is intended for installation in restricted access locations only and in equipment with a Type “B” or “E” installation code. Ensure chassis ground is properly connected.
