| Description | The cItpAclType object indicates which types of tests
will be processed on the each access list entry.
Each may contain one or more filters. The filter will
be processed ascending order(si,dpc...all). Each test
is evaluated and if true the packet is processed
according to cItpAclAction.
'si' : The cItpAclSi is the relevant column. The packet
is compared to cItpAclSi to determine if the
packet matches this filter.
'dpc' : The cItpAclDpc and cItpAclDpcMask are the relevant
columns. The packet is compared to cItpAclDpc
in conjunction with cItpAclDpcMask to determine
if the packet matches this access control.
The mask is first negated (~mask) and bitwise
AND is perform with mask and dpc.
'dpcMask' : Indicates that a mask is to be applied when the
dpc filter is specified. If the mask is not
specified then the mask is assumed to be all
zeros.
'opc' : cItpAclOpc and cItpAclOpcMask are the relevant
columns. The packet is compared to cItpAclOpc
in conjunction with cItpAclOpcMask to determine
if the packet matches this access control.
The mask is first negated (~mask) and bitwise
AND is perform with mask and opc.
'opcMask' : Indicates that a mask is to be applied when the
opc filter is specified. If the mask is not
specified then the mask is assumed to be all
zeros.
'pattern' : cItpAclPattern and cItpAclOffset are the
relevant columns. The matching criteria is
based on matching the pattern specified by
cItpAclPattern at offset cItpAclOffset from
the start of the packet.
'comment' : The cItpAclComment object provides an entry
that can be used to describe filters.
'cgpa' : The cItpAclCgpa, cItpAclCgpaMask,
cItpAclCgpaSsn and cItpAclCgpaSsnMask are the
relevant columns. The Calling Party Point code
is compare with cItpAclCgpaPC using the
ItpAclCgpaMask. Also, the cItpAclCgpaSsn
and cItpAclCgpaSsnMask are compared if specified.
'cgpaMask': Indicates that a mask is to be applied when the
cgpa filter is specified. If the mask is not
specified then the mask is assumed to be all
zeros.
'cgpaSsn' : Indicates that a Subsystem Number(SSN) is to
be checked when the cgpa filter is specified.
'cgpaSsnMask': Indicates that SSN mask is to be applied
when checking the SSN number for the cgpa
filter is specified. If the mask is not
specified then the mask is assumed to be all
zeros.
'cdpa' : The cItpAclCdpa, cItpAclCdpaMask,
cItpAclCdpaSsn and cItpAclCdpaSsnMask are the
relevant columns. The Called Party Point code
is compared with cItpAclCcpa using the
ItpAclCcpaMask. Also, the cItpAclCcpaSsn
and cItpAclCcpaSsnMask are compared if specified.
'cdpaMask': Indicates that a mask is to be applied when the
cdpa filter is specified. If the mask is not
specified then the mask is assumed to be all
zeros.
'cdpaSsn' : Indicates that a SSN is to be checked when the
cdpa filter is specified.
'cdpaSsnMask': Indicates that SSN mask is to be applied
when checking the SSN number for the cdpa
filter is specified. If the mask is not
specified then the mask is assumed to be all
zeros.
'selector': The Global Title Selector is used to select
which objects will be tested and in what order
the tests will be applied as follows.
x
The types of translations are different based on
the variant. In both, variants the translation
type and other parameters are used to provide the
following types of translations.
- Intermediate GTT resulting in MSUs routed to a
solitary point code
- Intermediate GTT resulting in MSUs load
balanced across two or more point codes
- Final GTT routed to a solitary point code
- Final GTT routed to a primary and backup
point-code and SSN (dominant mode)
- Final GTT load balanced across a group of
point-codes and subsystems
For ANSI the translation types are defined in
TABLE B.1/T1.112.3 of TR-NWT-000246. The ANSI
selector table may be a simple flat table/array of
256 Translation Types(0-255). In this method of
translation tables can be directly accessed using
the translation type from the Called Party Point
Code.
For ITU section 2.4.5 of ITU-T Q.714, defines the
use of the Global Tile Indicator(GTI), along with
Translation Type(TT), Network Plan(NP), and Nature
of Address Indicator(NAI), as selectors for the
table to perform the Global Title
Translation(GTT). In this cae the selector table
must be searched using a combination oF GTI, TT,
NP and NAI.
The objects cItpAclGtiSelector,
cItpAclGtiTranslateType, cItpAclGtiNumberingPlan,
cItpAclGtiNai, and cItpAclGtiEsv are the relevant
columns. These object will be used in the
following order based on variant and translation
type.
1 => cItpAclGtiNai
2 => cItpAclGtiTranslateType
3 => cItpAclGtiTranslateType
cItpAclGtiNumberingPlan
cItpAclGtiEsv
4 => cItpAclGtiTranslateType
cItpAclGtiNumberingPlan
cItpAclGtiNai
cItpAclGtiEsv
'aft' : The cItpAclAft, cItpAclAftMask,
cItpAclAftSsn and cItpAclAftSsnMask are the
relevant columns. The affected point code is
compared with cItpAclAftPC using the
ItpAclAftMask. Also, the cItpAclAftSsn
and cItpAclAftSsnMask are compared if
specified.
'aftMask': Indicates that a mask is to be applied when the
aft filter is specified. If the mask is not
specified then the mask is assumed to be all
zeros.
'all' : Used in conjunction with cItpAclAction to specify
defaults for packet that did not match any
specified access list entry. |
