Control
Channel
Interchange
Each port network has a pair of TDM busses (A and B). Each has a set
of time slots dedicated to the control channel. One bus at a time carries
the control channel in eac h PN. (daily, days of the week, or no -
prevents interchanges). (no)
System Clocks
Interchange For High and Critical Reliability syste ms, this option initiates a
Tone-Clock interchange in eac h port network possessing duplicated
Tone-Clock circuit pa cks. Each port network interc hanges into the
standby Tone-Clock for 20 sec onds and then bac k to the
originally-active Tone-Clock. This field indicates the days that
interchanges occ ur. (daily, days of the week, or no). “ No” prevents
interchanges. (no)
The system performs a Tone-Clock interchang e, activating the stand b y
Tone-Clock. After the newly-active Tone-Clock c ircuit pack is te sted, it
provides system cloc ks for its native port network. Then the system
interchanges to the origina lly active Tone-Clock circ uit pack.
