Page 45: Hdsl Loopbacks
This Appendix describes operation of the HDSL system with regard to detection of in-band and ESF facility data link loopback codes. The operation of the loopback commands in the ADTRAN HDSL system is compliant with the recommendation to ANSI recorded in T1E1.4/92. The HDSL network loopback points described below are shown in Figure A-1. -
Page 46: Loopback Process Description
HDSL T200 HTU-R, Span Powered, 60 mA Installation and Maintenance Practice Loopback Process Description In general, the loopback process for the HDSL system elements is modeled on the corresponding DS1 system process. Specifically, the HTU-C loopback is similar to an Intelligent Office Repeater loopback and the HTU-R loopbacks are similar to an inline T1 Repeater loopback. -
Page 47: Hdsl Loopback Codes
Appendix A, HDSL Loopbacks - HDSL Maintenance Modes In-band control code sequences are transmitted over the DS1 link by either the unframed or overwrite method. The HDSL elements respond to either method. The unframed method produces periodic control sequences and the normal DS1 framing bit is omitted. - Page 48 HDSL T200 HTU-R, Span Powered, 60 mA Installation and Maintenance Practice Table A-1.
