Page 50: Gnlb Loopback Test Procedures
Loopback Operation 150-231-165-01, Revision 01 GNLB L OOPBACK ROCEDURES To perform the GNLB loopback test procedure: Have the CO tester send the HRU (3-in-7) in-band loopup code for 5 seconds. You should be able to see that an HRU NREM loopback is in effect by observing the NREM message on the front panel display. (Loopback states are indicated by the green LOOP LED on the front panel and also display in the Span Status screen.) Have the CO tester transmit a T1 test signal into the HLU-231 and verify that the returned (looped) signal is error-free. - Page 51 HLU-231 may indicate one more or one less bit error, depending on the test set type and the number of frame bits contained in the block of errored bits. To avoid this uncertainty, PairGain recommends sending the IR commands unframed.
- Page 52 Loopback Operation 150-231-165-01, Revision 01 Once the test is complete, do one of the following: • If the system is to loopdown but remain ARMED, send the IR (Intelligent Repeater) LPDN code (universal loopdown). • If all the equipment is to be looped down, disarmed and returned to normal operation, send the disarm code 11100.

Page 58: Appendix C - Functional Operation
UNCTIONAL PERATION PairGain HDSL technology provides full-duplex services at standard T1 rates over copper wires between an HLU and an HRU, which comprise one HiGain system. HiGain systems use PairGain 2-Binary 1, Quartenary (2B1Q) HDSL transceiver systems to establish two, full-duplex, 784 kbps data channels between the HLU-231 and a remotely located HDU or HRU. -
Page 59: Power Consumption
150-231-165-01, Revision 01 Appendix C - Functional Operation OWER ONSUMPTION The three most important power parameters of an HLU are its maximum power consumption, its maximum power dissipation, and its maximum current drain. The Maximum Power Consumption is the total power that the HLU-231 consumes or draws from its -48 V shelf power source. -
Page 60: Power Consumption: With Doublers
Appendix C - Functional Operation 150-231-165-01, Revision 01 Power Consumption: With Doublers One or two doublers may be used in the HDSL loops between the HLU-231 List 6E and HRU. See Table 16 general doubler deployment rules. This section addresses HLU-231 List 6E operation with the HDU-451 List 1, 2, 3, and 4 doublers, the HDU-437 and 439 mini doublers, and the HDU-404, 407, and 409 micro doublers. -
