NetworkInterface.T1E1[x].LineCode

Specifies the ones density maintenance method used on the trunk line to maintain a clear channel transmission.

NetworkInterface.T1E1[x].LineCode = code

x = 0-(n-1) (0-based trunk number or range of trunk numbers where n equals the number of trunks on the board.)

Read/Write

String

HDB3

Note: For T1 trunks you must specify a value, typically B8ZS.

AMI | B8ZS | HDB3 | AMI_ZCS | AMI_BELL | AMI_DDS | AMI_GTE

NetworkInterface.T1E1[0..7].LineCodeCode = AMI

The valid T1 trunk formats are:

Format	Definition
AMI	Alternate mark inversion - standard line coding with no zero code suppression.
B8ZS	Binary 8-zero code suppression that uses patterns of bipolar violations to replace zero data bytes; especially useful for clear channel transmission.
AMI_ZCS	AMI with jammed bit 7 zero code suppression.
AMI_BELL	Same as AMI_ZCS.
AMI_DDS	AMI with zero data byte replaced with 1001 1000.
AMI_GTE	AMI with jammed bit 8 zero code suppression, except in signaling frames when jammed bit 7 is used if the signaling bit is zero.

The valid E1 trunk formats are:

Format	Definition
AMI	Alternate mark inversion - standard line coding with no zero code suppression.
HDB3	High density bipolar 3 code that uses patterns of bipolar violations to replace sequences of 4 zero data bits to maintain ones density on clear channel transmission.

NetworkInterface.T1E1[x].LineCode is optional.
