Example 2: TELEVIC
TELEVIC sends alarms where behavior depends on tone code or message contents.
If the alarm is described as TELEVIC, the system looks first for a string pattern (first blank or
first xx characters as specified in the L:xx description of the INPGM_Model_str field of the
eKERNEL_INPGM table (PROTOCOL CONVERTOR – L:03). If no length (L:xx) is specified,
the default value is 3. Characters of message or search until first blank character: NUR, SAN,
ASS, REA, MUG, and so on.
See documentation Table eKERNEL_inpgm.pdf.
If no such definition is found; the system looks for a matching tone code pattern (for authorized,
0, 1, 2, 3, 4, 5, 6, 7, 8, 9 or 0).
If again no definition is found, the system looks for an *OTHER definition.
Example 3 - National Instruments
The National Instruments distributed I/O modules FP-DI-300, FP-DI-301 and FP-DI-330
generate discrete input alarms, the I/O module FP-AI-100 generates analogue input alarms.
Both modules are configured in eIO_MODULE, eIO_AI and eIO_DI tables. In the latter two
files the alarm type can be defined, default is D-INPUT and A-INPUT. If these defaults are
used, ALA_Descr_id_str must have records for D-INPUT and A-INPUT.
Example 4 - Guarding
A special feature in the eCAP input program consists of a method to verify the amount of time
between two requests. If a specific type has elapsed, this can be caused by a failure in the
external alarm system or the physical interface. In such case, GUARDING can be
implemented. This is configured in the eKERNEL_GUARDING table. The link between
eKERNEL_GUARDING and eKERNEL_ALARM is performed through an alarm identifier, but
Avaya recommends specifying GUARDING in the alarm description field.
An authorized of an entry typically found in this field is as follows: GUARDING
ALA_Remove_after_str
This field can have the value *SENT or *RESET.
If the field value is *SENT, the message is removed after successfully sending the message.
If the field value is *RESET, the message remains in the database until an explicit reset signal
is received from the alarm system.
Again, this value is generally depending of the proprietary implementation of the alarm system
and the attached peripherals. Some devices can send a SET and RESET indication (for
authorized, a switch button van be set to on or off); others cannot generate a RESET (for
authorized, a push button can only generate a push signal while pressing the contact).
In some cases you can have difficulty determining whether alarms have reset or not. In fact,
some third-party alarm system vendors are not aware of the signals provided. In these cases,
