Table A-2. DSX-1 Interface Options (1 of 2)
Port Status
Possible Settings: Enable, Disable
Default Setting: Enable
Determines whether the port can be configured and used.
Enable – The port can be configured and used.
Disable – The port cannot be configured or used. Configuration fields for the port are
inaccessible, no alarms or traps associated with the port are generated, and the LED
associated with the port is OFF.
Line Framing
Possible Settings: ESF, D4
Default Setting: ESF
Specifies the framing format to be used by the DSX-1 interface.
T Line Framing is only available when the unit is configured as an LTU. The NTU is
automatically configured to match the framing format used by the LTU.
ESF – ESF framing formatting is used for transmitted and received data over the DSX-1
Interface.
D4 – D4 framing format is used for transmitted and received data over the DSX-1
Interface.
Line Coding
Possible Settings: AMI, B8ZS
Default Setting: B8ZS
Specifies the line coding format to be used by the DSX-1 interface.
AMI – Indicates the line coding format used by the DSX-1 interface is Alternate Mark
Inversion (AMI).
B8ZS – Indicates the line coding format used by the DSX-1 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.

533–655 feet – Provides equalization for a cable length up to 655 feet.
Excessive Error Rate Threshold
Possible Settings: 1E– 4, 1E–5, 1E– 6, 1E–7, 1E– 8, 1E–9
Default Setting: 1E–4
Determines the error rate at which an excessive error rate (EER) condition is recognized.
The rate is the ratio of the number of CRC5 errors to the number of bits received in a
certain period.
1E–4 – 1E-9 – The rate at which EER is recognized.
