Software Initiated Tone-Clock Interchanges
Tone-Clock interchanges may be initiated by software in two ways:
1. A scheduled Tone-Clock or IPSI circuit pack interchange occurs according to the
parameters set by change system-parameters maintenance. This parameter can be
disabled or set to run weekly, the default is for it to occur daily, at a time specified in the
system-parameters list for scheduled maintenance to begin. This interchange will be
blocked, if the non-preferred Tone-Clock or IPSI circuit pack in a PN has been selected with
set tone-clock or set ipserver-interface. Also if the standby Tone-Clock or IPSI
system-parameters list for scheduled maintenance to begin. This interchange will be
blocked, if the non-preferred Tone-Clock or IPSI circuit pack in a PN has been selected with
set tone-clock or set ipserver-interface. Also if the standby Tone-Clock or IPSI
has been set to the busyout state, or if the clock generation capability is known to be
impaired. When this scheduled interchange occurs, the standby Tone-Clock or IPSI circuit
pack becomes active for twenty seconds to test its ability to generate clock signals. For IPSI
scheduled interchanges, the other IPSI modules located on the IPSI circuit pack, i.e. the
Packet interface and Archangel are also tested. After testing the IPSI is returned to standby
mode.

2. For non IPSI Port Networks, unscheduled interchanges occur when on-board Tone-Clock
circuit-pack maintenance, or ongoing switch maintenance test of the TONE-BD, TONE-PT
or the TDM-CLK uncover failures serious enough to raise a MAJOR or MINOR alarm
against the active Tone-Clock circuit pack.

against the active Tone-Clock circuit pack.
For IPSI Port Networks, unscheduled IPSI/Tone-Clock interchanges may occur any time
as a part of an unscheduled IPSI interchange. The IPSI interchange may be the result of
Tone-Clock, PKT-INT, or EAL faults.

Note:
The following information is for non IPSI port networks.
The TN780 Tone-Clock circuit pack uses three firmware configuration parameters for
international support [G3i V2]. The following two are automatically set by the software load for
the targeted country:
international support [G3i V2]. The following two are automatically set by the software load for
the targeted country:
●
The circuit pack’s country-code (USA, ITALY, AUSTRALIA, etc.)
●
The circuit pack’s companding mode (mu-Law or A-Law)
The third configuration parameter is used only for Italy (country code: ITALY), and selects
whether new versus old ISPT (Istituto Superiore Poste Telegrafi) tones will be used for dial and
confirmation tones. Values for dial confirmation tone can be set independently on the change
tone-generation form. Whenever such changes are made, the effects are immediately
whether new versus old ISPT (Istituto Superiore Poste Telegrafi) tones will be used for dial and
confirmation tones. Values for dial confirmation tone can be set independently on the change

enforced on all TN780 Tone-Clock circuit packs without disrupting tone or timing services.
