The DS1-CO maintenance object monitors and m aintains a CO trunk port on
either a TN767 DS1 Interface circuit pac k or a TN464 UDS1 Interface circuit
pack. Throughout this discussio n, the term DS1 circuit pack app lies to both. See
‘‘DS1-BD (DS1 Interface Circuit Pack)’’ and ‘‘UDS1-BD (UDS1 Interface Circuit
Pack)’’ in this chapter for more information ab out these circuit pac ks. The DS1
circuit pack supports low level CO trunk si gnaling interfac es for both
ground-start and loop -start trunks. This maintenance strategy c overs the in-line
errors log, initialization tests, period ic tests, scheduled tests, demand tests, and
alarm resolution.
Three trunk service states are specified by DS1 CO trunk maintenance:
Error Log Entries and Test to Clear Values
