cvcmABCDBitTemplateConfigTable
1.3.6.1.4.1.9.9.389.1.1.1
This table is used to configure templates
on the module/card. These templates provide
mapping information between the incoming CAS
ABCD signaling bit patterns and the outgoing
ABCD signaling bit patterns. The outgoing
bit patterns are derived from the incoming
bit patterns by applying a set of actions to
each incoming bit.
Thus, this table essentially contains
configuration information about CAS ABCD
signaling bits.
The ABCD bit carries signaling information
describing off-hook, on-hook event etc on a
T1 or E1. The pattern representations
differ in CAS variants on a T1 and E1.
For example:
On T1:
E&M protocol ABCD seized is 1100
On E1:
CAS-R2 signaling ABCD seized is 0001
This table is configured on a per module/ card
basis.
Further, one can have multiple different actions
performed on the different bits (A, B, C or D)
consecutively for the same incoming ABCD bit
index. However, a given bit position can only
have one action being performed on it for a given
incoming bit pattern.
For example, for a given incoming bit index,
one can define the 'A' bit to be set to 0, the 'B'
bit to be swapped with the 'C' bit, the 'C' bit to be
swapped with the 'B' bit and the 'D' bit to be inverted.
Thus, using this table, the user can create a template
with name (cvcmCasTemplateName) 'Template1' where for
incoming pattern (cvcmABCDIncomingPattern) '0000',
the action on the A bit (cvcmCasABitAction) is
'casBitSetToZero', the action on the B bit
(cvcmCasBBitAction) is 'casBitCBit', the action on the
C bit (cvcmCasCBitAction) is 'casBitBBit' and the action
on the D bit (cvcmCasDBitAction) is 'casBitInvertBit'.
This will create one entry in 'Template1' where the
resultant outgoing pattern (cvcmABCDOutgoingPattern)
will be '0001'.
