Configuration Option Tables
Table A-2. DSX-1 Interface Options (2 of 2)
Line Coding Format
Possible Settings: AMI, B8ZS
Default Setting: B8ZS
Specifies the line coding format to be used by the DSX interface.
AMI – Indicates the line coding format used by the DSX interface is Alternate Mark
Inversion (AMI).
B8ZS – Indicates the line coding format used by the DSX interface is B8ZS.
Line Equalization
Possible Settings: 0-133, 133-266, 266-399, 399-533, 533-655
Default Setting: 0-133
Compensates 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 Failure
Possible Settings: Enable, Disable
Default Setting: Enable
Specifies the action taken on the signal transmitted to the DSX-1 when a valid signal
cannot 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 an
LOS or OOF condition on the network interface.
Disable – The failed signal on the interface is passed through to the DSX-1 network
unchanged.
Send All Ones on DSX-1 Failure
Possible Settings: Enable, Disable
Default Setting: Enable
Specifies the action taken on the signal transmitted to the network when a valid signal
cannot 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 LOF
condition on the DSX-1 interface.
Disable – The failed signal on the interface is passed through to the DSX-1 network
unchanged.
Primary Clock Source
Possible Settings: DSX-1, Internal
Default Setting: Internal
Specifies 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.
