ConfiguringCableLength

WhenyouconfigureyourCT1trunkcards,youmustincludethedistanceofthecable

connectedtothefeaturecard.Tospecifythisdistance,youmustusethecablelength

command.NocablelengthcommandisrequiredforCE1trunkcards.

Ifyouchangethecablelengthwheninstallingandcablinganewtrunkcard,youneed

tospecifycablelengthinyoursoftwareconfiguration.Thecablelengthcommandis

designedtorecognizetwobasicfixedsettings:

• CableLengthShort

• CableLengthLong

CableLengthShort

Thefollowingcablelengthshortconfigurationsdefinethelengthrange(infeet),

betweenyourNetworkAccessServer(NAS)andyourrepeater.Thecablelength

shortcommandincludesthefollowingsettings:

• 133feet(0133feet)

• 266feet(134266feet)

• 399feet(267399feet)

• 533feet(400533feet)

• 655feet(534655feet)

NoteAlthoughyoucanspecifyacablelengthfrom0to655feet,thehardwareonly

recognizesfixedconfigurationlengths.Forexample,ifyourcablelengthis50feet

betweenyourNASandyourrepeater,youshouldconfigureyourcablelengthusing

the133feetsetting.Ifyoulaterchangethecablelengthto200feet,youshould

reconfigureyourcablelengthusingthe266feetsetting.
