D9068 | Operation and Installation Guide | 4.0 System Operation
Phone 2 Backup is the default
and recommended setting for all
event types. Changing this
setting can cause messages to
transmit to the central
station.
Each event is routed through the
telephone to the central station in one
of four ways:
1. PHONE 1 Only: Only uses Phone Number
1.
2. PHONE 2 Only: Only uses Phone Number
2.
3. PHON 1 AND 2: Uses Phone Number 1 and
Phone Number 2.
4. PHN 2 BACKUP: Primarily uses Phone
Number 1 with Phone Number 2 as a
backup when communication cannot be
established with Phone Number 1. PHN
2 BACKUP is the default setting for
the D9068.
Refer to
Appendix
page 63 for more information about
report steering.
Use the default setting of
Phone 1 with Phone 2 as a
backup. If this setting
changes, the telephone lines
used also change and the
messages might not transmit to
the central station. Table 6 on
page 21 does not apply to the
PHONE 1 ONLY and PHONE 2 ONLY
route settings.
4.1.5 Call Attempts
When an event must be communicated to
the central station, the D9068 makes up
to ten attempts to communicate with the
central station until the call is
answered.
Table 6 on page 21 shows the procedure
that the D9068 follows in attempting to
communicate with the central station
when it is programmed to use Phone 2
Backup (default) or Phones 1 and 2.
4.1.6 Communication Fault
When a report must be transmitted to the
central station, the D9068 makes up to
ten attempts to communicate (refer to
Table 6 on page 21). If after ten
attempts the D9068 does not connect
successfully, a communication failure
occurs and a Comm Fault Report is
generated.

Bosch Security Systems, Inc. | 3/13 | F01U071094-07
Then, the D9068 makes up to ten attempts
to communicate the Comm Fault to the
central station. If the D9068 does not
succeed, the original report and the
Comm Fault Report clear from the D9068's
buffer.
The total time from the first sequence
of attempts to a communications failure
is approximately 15 min. This time
varies depending on how ACK Wait time is
programmed. A Comm Fault Restoral Report
transmits when communication restores
after a communications failure.
4.1.7 Programming Fault
Programming faults indicate if specific
telephone programming items are not
completed.
A programming fault occurs when:
Both account numbers are not changed
from their default values of 0000.
No telephone number is programmed.
A report is routed to Phone Number 1
and either Account Number 1 is 0000
or Phone Number 1 is invalid.
A report is routed to Phone Number 2
and either Account Number 2 is 0000
or Phone Number 2 is invalid.
A report is routed to Phone Numbers 1
and 2 or to Phone 1 with Phone 2 as
backup. At least one of the account
numbers is 0000 or one of the
telephone numbers is invalid.
4.1.8 Data Lost and Limited Reports
A Data Lost Report generates when an
event cannot transmit to the central
station. This occurs when:
The reporting buffer contains the
maximum of 32 events and another
event occurs. The lowest priority
event in the report buffer is deleted
and replaced by Data Lost unless the
report is already a Data Lost Report.
If the new event has a higher
priority than an event already in the
report buffer, the lower priority
event is discarded and replaced with
the higher priority event. When the
buffer is full, the lowest priority
event is discarded when a new event
occurs. The Data Lost Report is the
last event sent, emptying the report
buffer. If the buffer fills again,
another Data Lost Report is sent.
