dsx3Unframed

e3Unframed

Line Coding

Type of zero code suppression used on the line, which in turn affects a number of its characteristics. Choose one from the pop-up menu:

dsx3B3ZS

e3HDB3

Line Length

The line length. Choose one from the pop-up menu:

Line Check AIS Bits

Determines the when AIS condition is declated. Choose one from the pop-up menu:

checkCbits: AIS is declared when 1010 pattern is found and C-Bits are all zero.

ignorebits: An AIS condition is declared when the AIS pattern 1010 is detected irrespective of the state of the C-Bits.

Line Loopback Command

Represents the loopback configuration of the DS3/E3 interface. Choose one from the pop-up menu:
