2 Section 61245201L1-5, Issue 3 61245201L1-5C With the exception of the physical dimensions of the units, the FNID and T200 FNID units are functionally identical. The FNID terminates local loop DSL signals originating from the Central Office (CO) unit and transforms the DSL signal into fractional T1 signals to be delivered to the customer.
3 Section 61245201L1-5, Issue 3 61245201L1-5C 3. CONNECTIONS All connections of the FNID are made through card edge connectors. Table B gives the card edge pin assignments for the FNID circuit pack.
4 Section 61245201L1-5, Issue 3 61245201L1-5C 5. CONTROL PORT OPERATION The FNID provides a faceplate-mounted DB9 connector that supplies an RS-232 interface for connection to a controlling terminal. The pinout of the DB9 is illustrated in Figure 4. The terminal interface operates at data rates from 2.

A-1 Section 61245201L1-5, Issue 3 61245201L1-5C Appendix A FT1 Loopbacks 1. GENERAL This Appendix is an overall reference to the loopback capabilities of the ADTRAN Fractional T1 system. Included in this Appendix is a description of the FT1 loopbacks and the methods for activating the FT1 loopbacks.
A-2 Section 61245201L1-5, Issue 3 61245201L1-5C There is one loopback available to the FT1 Repeaters. The FT1 Repeater Network loopback is a digital loopback toward the CO as shown in Figure A-4. The loopbacks are initiated by the DDS latching loopback codes for NEI Position 1 (N1000001) for FT1 #1 or NEI Position 2 (N100001) for FT1 Repeater # 2.
A-3 Section 61245201L1-5, Issue 3 61245201L1-5C 3. LOOPBACK ACTIVATION/DEACTIVATION This section describes loopback activation and deactivation methods for the ADTRAN Fractional T1 system. Loopback activation and deactivation is controlled with the push-button located on the front panel, through craft interface, or latching loopback codes.
