Page 30: Loopback Operation
Loopback Operation OOPBACK PERATION HiGain HDSL2 has a family of loopback options for analyzing circuit functionality. The loopback signal is transmitted and returned to the sending device for comparison. This allows you to verify the integrity of the HDSL2 channels to the H2TU-C, the H2TU-C DSX-1 interface, and the DS1 channels to the customer. Loopback options include: •... -

Page 32: Special Loopback Commands
In addition to the GNLB loopback command mode, a HiGain HDSL2 system can be configured for one of three special loopback command modes. These command modes, A2LB, A3LB, and A4LB, are selected from the ADC Options maintenance terminal screen or by using the MODE and SEL buttons on the H2TU-C front panel. Once a loopback mode is activated, other loopback commands can be sent by a test set connected to the craft port on the H2TU-C or H2TU-R front panel. -

Page 34: A2Lb Test Procedures
Loopback Operation A2LB Test Procedures Using the codes listed in Table 11, a network tester can activate NLOC, NRG or NREM loopbacks (or SMJK, if enabled). A tester at the customer premises can activate CLOC, CRG, or CREM loopbacks. Table 11.

Page 36: A3Lb And A4Lb Test Procedures
Loopback Operation A3LB and A4LB Test Procedures The H2TU-C can be looped back by sending the Addressable Office Repeater (AOR) LPBK activation code 1111-1111-0001-1110 (FF1E) for at least 5 seconds. This causes the H2TU-R-402 to enter the NLOC state. The H2TU-C Loopback Time-out (LBTO) setting determines the duration of this loopback unless it is overridden by the reception of a second identical 16-bit loopup command before the timer expires. -
