Installation Push Button and LED Indicator Interaction The following is a further explanation of the required interaction between the front panel pushbuttons and LEDs. When no port has been selected, (no flashing port LEDs) only the PORT SELECT push button is enabled, and the LLOOP, RLOOP, and BERT LEDs indicate the status (refer to Table Table 7.
SHDSL 2-Wire/4-Wire NTU Product Series Installation and Maintenance Guide Power Supply The various models support one of the following power schemes: • Local AC powered only • Local DC powered only • Span powered with local DC power auto-switchover NOTICE No adjustments, strapping, or configuration changes are necessary to power the units.
Connections SHDSL Pinout The SHDSL port uses a TNV-3 rated, 135W impedance, RJ-45 connection with signals and pinouts (refer to Table 10). Table 10. SHDSL Port RJ-45 Pinout Circuit Name Function Tip 2 4-Wire Loop, 2 Pair Tip Ring 2 4-Wire Loop, 2 Pair Ring Not Connected Tip 1...
This product supports a 37-pin (DB-37) female connection through a 12-inch V.35-to-V.36 adapter cable that complies to ISO 4902 pinouts (ADTRAN P/N 1225004L1). This cable connects to the NTU rear panel V.35 M34 Winchester female connector and provides ID pins to automatically set the Nx64K type to V.36.

Connections X.21 Pinout The SHDSL 2-Wire/4-Wire NTU Product Series rear panel provides a 15-pin female connection that complies with ISO 4903 pinouts. The X.21 interface implementation is intended to be for leased lines with no end-to-end signaling or byte timing. Refer to Table 14 for the X.21 pinouts.
SHDSL 2-Wire/4-Wire NTU Product Series Installation and Maintenance Guide Optioning Timeslot Cross-Connect Map The SHDSL 2-Wire/4-Wire NTU Product Series supports the configuration of multiple services. A service is comprised of an arbitrary collection of timeslots from the SHDSL interface that are configured through the management interface.
Optioning Timeslot Allocation The SHDSL timeslots are individually mapped to the required G.703/G.704 and Nx64k service timeslots on a one-to-one basis. As illustrated in Figure 11 Figure 12 on page 24, both contiguous and non-contiguous service allocations are allowed, as long as the chrono- logical transmission ordering of timeslots is maintained.

Troubleshooting Troubleshooting For troubleshooting, the SHDSL 2-Wire/4-Wire NTU provides loopback tests, an internal Bit Error Rate Tester, and bad splice detection. Local and Remote Loopbacks for Ports and Services For troubleshooting purposes, the SHDSL 2-Wire/4-Wire NTU provides five types of loopback tests for each interface port and each data service.

SHDSL 2-Wire/4-Wire NTU Product Series Installation and Maintenance Guide Searching for Pattern The SHDSL 2-Wire/4-Wire NTU is able to reset the BERT counters when requested to do so by an NMS or VT100 test screen. Injection of a single bit error from the NMS, VT100 test screen, or front panel BERT push button is also possible.
Troubleshooting Bad Splice Detection (TScan) The SHDSL 2-Wire/4-Wire NTUs provide bad splice protection using the ADTRAN propri- etary Runtime TScan 2.0 splice protection feature. TScan splice detection is a non-intrusive algorithm that enables SHDSL 2-Wire/4-Wire NTUs to detect anomalies (bad splices) in the copper pair.
SHDSL 2-Wire/4-Wire NTU Product Series Installation and Maintenance Guide • If two or more count register exceed the threshold and are of equal count, then the distance count closest to the unit displays as a bad splice because the detector is more accurate the closer the anomaly is to the unit.
Troubleshooting Unit Mode: 21-Nov-06 11:01:32 Circuit ID: Terminal Mode: Local Restart Bad Splice Detector Are you sure you want to restart the bad splice detector and lose all 24 hour count history (Y/N)? Selection: System Help Figure 18. Restart Bad Splice Detector Screen The Restart Bad Splice Detector screen options are shown in Table Table 18.
SHDSL 2-Wire/4-Wire NTU Product Series Installation and Maintenance Guide Bad Splice Detection (TSCAN) 24 Hour Counts Screen Provisioning The Bad Splice (TSCAN) 24 Hour Counts screen displays the history register. If the unit is handshaking or training, the splice loop rates and count registers do not update. If the unit is trained, it updates the splice current day data registers.
