58 CHAPTER 4: BASIC CONFIGURATION OF PORTS, PATHS, AND CONNECTORS must match the attached communication device. AMI or B8ZS should be used for T1 connectors and HDB3 should be used for E1 connectors. NRZ and NRZI are not valid options on Ultra-WAN interfaces. 5 Set the LineDistance as appropriate for your setup using: SETDefault ! -PAth LineDistance = LH1|LH2|LH3|LH4|SH1|SH2| SH3|SH4|SH5|SH7 The LineDistance parameter determines the supported long haul (LH) or short haul (SH) line distance. For T1 lines, long haul and short haul settings are supported. Further granularity is provided in units of dB for long haul, and in units of feet for short haul. For E1 lines, only short haul is supported. Use SH7 for E1 lines.

must match the attached communication device. AMI or B8ZS should be
used for T1 connectors and HDB3 should be used for E1 connectors. NRZ
and NRZI are not valid options on Ultra-WAN interfaces.

Set the LineDistance as appropriate for your setup using:
SETDefault !<path> -PAth LineDistance = LH1|LH2|LH3|LH4|SH1|SH2|
SH3|SH4|SH5|SH7
The LineDistance parameter determines the supported long haul (LH) or
short haul (SH) line distance. For T1 lines, long haul and short haul
settings are supported. Further granularity is provided in units of dB for
long haul, and in units of feet for short haul.
For E1 lines, only short haul is supported. Use SH7 for E1 lines.
6
Enable the connector using:
SETDefault !<path> -PAth ConnControl = Enabled
Connector parameter settings are not applied until the connector is
enabled.
