IDSL/DDS Trouble Code
The IDSL/DDS system provides a quick diagnosis in
the case of a circuit condition where continuity is
broken. The trouble code type received by a tester
determines whether the open condition is occurring on
the local loop or at the customer premises. In the
event of a 2-wire DSL loss of signal, loss of sync, or
open condition caused by an open conductor or
disconnected 2-wire loop, the SLC 5 U-BR1TE III
transmits a Mux-Out-of-Sync trouble code (MOS
9Ah) into the network as shown in Figure 11. During
a similar out-of-service condition at the customer
premises, the IDSL OCU-R transmits Abnormal
Station Code (ASC 9Eh) upstream into the network as
shown in Figure 11.
4. MAINTENANCE
The U-BR1TE III does not require routine
maintenance for normal operation.
