Network Interface Configuration Options

Table C-1. Network Interface Configuration Options (1 of 3)

Line Framing Format: ESF (Factory 1) D4 (Factory 2)
D4 ESF
The framing format to be used on the network interface.
D4 – Configures for the D4 framing format.
ESF – Configures for the Extended Superframe format.
Line Coding Format: B8ZS (Factory 1) AMI (Factory 2)
AMI B8ZS
The line coding format to be used on the network interface.
AMI – Configures for the Alternate Mark Inversion coding format.
B8ZS – Configures for the Bipolar 8 Zero Suppression coding format.
Bit Stuffing: 62411
62411 Part68 Disable
Determines when bit stuffing is performed to meet the ones density requirements for
data transmission on the network. You must choose the maximum number of
consecutive zeros the DSU/CSU can receive before it inserts a one.
62411 – Specifies that a one be inserted in the data stream after 15 consecutive zeros
or when the density of ones falls below 12.5% (complies with AT&T TR 62411).
Part68 – Specifies that a one be inserted in the data stream after 80 consecutive zeros
(complies with FCC Part 68).
Disable – Disables bit stuffing so that ones density is not enforced.
NOTES: To comply with Canadian DOC CS-03 regulations, equipment installed
in Canada must be configured to select 62411.
To comply with USA Part 68 regulations, equipment installed in the USA
must be configured to select Part 68.
This configuration option is only available if the network interface line
coding format is set to AMI.
Line Build Out (LBO): 0.0
0.0 –7.5 –15 –22.5
The line build out (LBO) for the signal transmitted to the network.
