Configuration Option TablesA-58774-A2-GB20-10 December 1998Table A-2. DSX-1 Interface Options (2 of 2)Line Coding FormatPossible Settings: AMI, B8ZSDefault Setting: B8ZSSpecifies the line coding format to be used by the DSX interface.AMI – Indicates the line coding format used by the DSX interface is Alternate MarkInversion (AMI).B8ZS – Indicates the line coding format used by the DSX interface is B8ZS.Line EqualizationPossible Settings: 0-133, 133-266, 266-399, 399-533, 533-655Default Setting: 0-133Compensates for signal distortion for a DSX-1 signal over a given distance.0–133 feet – Provides equalization for a cable length up to 133 feet.133–266 feet – Provides equalization for a cable length up to 266 feet.266–399 feet – Provides equalization for a cable length up to 399 feet.399–533 feet – Provides equalization for a cable length up to 533 feet.533–655 feet – Provides equalization for a cable length up to 655 feet.Send AIS on Network FailurePossible Settings: Enable, DisableDefault Setting: EnableSpecifies the action taken on the signal transmitted to the DSX-1 when a valid signalcannot be recovered from the network interface (LOS or OOF).Enable – An Alarm Indication Signal (AIS) is sent to the DSX-1 port in the event of anLOS or OOF condition on the network interface.Disable – The failed signal on the interface is passed through to the DSX-1 networkunchanged.Send All Ones on DSX-1 FailurePossible Settings: Enable, DisableDefault Setting: EnableSpecifies the action taken on the signal transmitted to the network when a valid signalcannot be recovered from the network interface (LOS or OOF).Enable – A pattern of all ones is sent to the DSX-1 port in the event of an LOS or LOFcondition on the DSX-1 interface.Disable – The failed signal on the interface is passed through to the DSX-1 networkunchanged.Primary Clock SourcePossible Settings: DSX-1, InternalDefault Setting: InternalSpecifies where the unit will derive its timing from.Internal – The clock source is derived from the internal oscillator.DSX-1 – The clock source is derived from the DSX-1 interface.
