Note
• The UCD Time Table is not available for incoming extensions or transferred calls.
• The overflow extension is the IRNA destination of the hunting group or the CO line group
assigned by programme "[134-135] Hunting Intercept — Day/Night" or "[457] Intercept
Extension ". If both of them are assigned, the IRNA destination of the hunting group will
be effective.
• If the overflow extension is not assigned, the system will not answer the call and waits for
an idle extension.
• If the Time Table number is not assigned, the system will not answer the call. In this case,
IRNA will be employed.
• In sequence assignment, "Sx" can be assigned to a space other than the first only when
another "Sx" is assigned in the first space.
• In sequence assignment, an assignment after "TR", "RT" or "Blank" is not available.
• If a timer is the first item in a Time Table sequence, it will delay answering according to the
Timer's setting. The caller will hear a ringback tone.
• Music on Hold after an OGM can be changed to a ringback tone by programme "[990]
System Additional Information, Area 01 — Bit 1."
