4 Point Code and CIC Translation Configuration
This chapter describes the procedures necessary to configure the Point Code and CIC Translation feature.
4.1 Introduction
The Point Code and CIC Translation (PCT) feature allows the EAGLE to change the destination point code (DPC) and originating point code (OPC) of an MTP-routed MSU to previously configured values. This functionality allows external networks to continue using the old point codes by emulating and mapping them to the new real point codes within the networks. The feature can also be used to change the circuit identifier code (CIC) for the MSU.
24-bit ITU-N point codes, spare point codes, and private point codes are not supported by PCT entries.
Network nodes can send and receive traffic to and from the emulated point code (EPC) without knowing the real point code that is being emulated by the emulated point code. This ability allows the real point code to be changed transparently from the rest of the network, which can continue using the emulated point code to route traffic.
For each incoming MTP-routed MSU, a DPC lookup is performed if the PCT feature is applied either by using the global setting defined by the chg-stpopts
command or using the setting for the incoming linkset defined by the chg-lsopts
command. If a translation is found during the DPC lookup, then the DPC of the MSU is replaced by the real point code as the MSU is received by the EAGLE. If the matching translation also contains provisioning for CIC translations, then the CIC of the MSU is changed to the value from the real CIC range.
For each incoming MTP-routed MSU, a DPC lookup and an OPC lookup are performed. If a translation is found during the DPC lookup, then the DPC of the MSU is replaced by the real point code as the MSU is received by the EAGLE. If a real CIC was provisioned in the translation, then the CIC of the MSU is changed to the value from the real CIC range.
If no matching translation is found during the DPC lookup, the OPC lookup is performed. If a translation is found during the OPC lookup, then the OPC of the MSU is replaced by the emulated point code as the MSU leaves the EAGLE. If the matching translation also contains provisioning for CIC translations, then the CIC of the MSU is changed to the value from the emulated CIC range. The OPC lookup is also performed on MTP-routed MSUs which are processed by the service module after feature processing has completed but before the service module sends the MSUs to an outbound LIM for routing. The OPC lookup is performed only on MSUs whose OPC is not the EAGLE's point code, a capability point code, or a secondary point code.
If no matching translation is found during the DPC lookup, the OPC lookup is performed. If a translation is found during the OPC lookup, then the OPC of the MSU is replaced by the emulated point code as the MSU leaves the EAGLE. If an emulated CIC was provisioned in the translation, then the CIC of the MSU is changed to the value from the emulated CIC range. The OPC lookup is also performed on SCCP MSUs after the GTT feature processing has completed but before the service module sends the MSUs to an outbound LIM for routing. The OPC lookup is performed only on MSUs whose OPC is not the EAGLE's point code, a capability point code, or a secondary point code.
- Changing the Point Code and CIC Translation Quantity - Used to enable the number of PCT entries that the EAGLE can contain. The EAGLE can contain a maximum of 1000 PCT entries.
- Adding a Point Code and CIC Translation Entry - Used to add a PCT entry to the database.
- Configuring the Point Code and CIC Translation STP Option - Used to configure a system-wide option for controlling the behavior of the PCT feature. This option has three values.
on
– The PCT feature is applied to all MSUs.off
– The PCT feature is not applied to any MSUs. This is the default value for this option.lset
– The PCT feature is applied to incoming MSUs or outgoing MSUs on a linkset whosePCT
option value ison
.
- Configuring the Point Code and CIC Translation Linkset Option - Used to configure the
PCT
value for a specific linkset when the system-wide option is set tolset
. This option has two values.on
– The PCT feature is applied to incoming MSUs or outgoing MSUs on a linkset.off
– The PCT feature is not applied to incoming MSUs or outgoing MSUs on a linkset. This is the default value for this option.
- Removing a Point Code and CIC Translation Entry - used to remove a PCT entry from the database.
4.2 Changing the Point Code and CIC Translation Quantity
This procedure is used to increase the number of PCT (point code and CIC translations) entries that are allowed in the EAGLE. The EAGLE can contain a maximum of 1000 PCT entries.
The enable-ctrl-feat
command enables the PCT quantity by specifying the part number for the PCT quantity and the PCT quantity’s feature access key with these parameters.
:fak
– The feature access key supplied by Oracle. The feature access key contains 13 alphanumeric characters and is not case sensitive. If you do not have the feature access key for the PCT quantity you wish to enable, contact your Oracle Sales Representative or Account Representative.
:partnum
– The Oracle-issued part number for the PCT quantity shown in Table 4-1.
Table 4-1 PCT Quantities and Part Numbers
Part Number | PCT Quantity |
---|---|
893037201 | 25 |
893037202 | 50 |
893037203 | 75 |
893037204 | 100 |
893037205 | 150 |
893037206 | 200 |
893037207 | 250 |
893037208 | 1000 |
The enable-ctrl-feat
command requires a valid serial number for the EAGLE to be configured in the database, and that this serial number is locked. This can be verified with the rtrv-serial-num
command. The EAGLE is shipped with a serial number in the database, but the serial number is not locked. The serial number can be changed, if necessary, and locked once the EAGLE is on-site, by using the ent-serial-num
command. The ent-serial-num
command uses these parameters.
:serial
– The serial number assigned to the EAGLE. The serial number is not case sensitive.
:lock
– Specifies whether or not the serial number is locked. This parameter has only one value, yes
, which locks the serial number. Once the serial number is locked, it cannot be changed.
Note:
To enter and lock the EAGLE’s serial number, theent-serial-num
command must be entered twice, once to add the correct serial number to the database with the serial
parameter, then again with the serial
and the lock=yes
parameters to lock the serial number. You should verify that the serial number in the database is correct before locking the serial number. The serial number can be found on a label affixed to the control shelf (shelf 1100).
Once the PCT quantity is enabled with the enable-ctrl-feat
command, the PCT quantity is also turned on. The chg-ctrl-feat
command is not necessary to turn on the PCT quantity.

To add a PCT entry, a PCT quantity must be enabled. Adding the new PCT entry cannot exceed the enabled PCT quantity. The enabled PCT quantity is shown in the rtrv-pct
output. The EAGLE can contain a maximum of 1000 PCT entries. Perform the Changing the Point Code and CIC Translation Quantity procedure to enable the required PCT quantity if adding the new PCT entry will exceed the enabled PCT quantity and the current PCT quantity is less than 1000.
Canceling the RTRV-RTE
Command
Because the rtrv-rte
command used in this procedure can output information for a long period of time, the rtrv-rte
command can be canceled and the output to the terminal stopped. There are three ways that the rtrv-rte
command can be canceled.
- Press the
F9
function key on the keyboard at the terminal where thertrv-rte
command was entered - Enter the
canc-cmd
without thetrm
parameter at the terminal where thertrv-rte
command was entered - Enter the
canc-cmd:trm=<xx>
, where<xx>
is the terminal where thertrv-rte
command was entered, from another terminal other than the terminal where thertrv-rte
command was entered. To enter thecanc-cmd:trm=<xx>
command, the terminal must allow Security Administration commands to be entered from it and the user must be allowed to enter Security Administration commands. The terminal’s permissions can be verified with thertrv-secu-trm
command. The user’s permissions can be verified with thertrv-user
orrtrv-secu-user
commands.
For more information about the canc-cmd
command, refer to Commands User's Guide.

– The emulated point code of the PCT entry shown in the EPCA
, EPCI
or EPCN
columns.
:realpc/realpca/realpci/realpcn
– The real point code of the PCT entry shown in the REALPCA
, REALPCI
or REALPCN
columns.
:filtpc/filtpca/filtpci/filtpcn
– The filter point code of the PCT entry shown in the FILTPCA
, FILTPCI
or FILTPCN
columns.
:si
– The service indicator value of the PCT entry shown in the SI
column.
:ssn
– The subsystem number value of the PCT entry shown in the SSN
column.
:ecics
– The emulated CIC start value of the PCT entry shown in the ECICS
field.
:ecice

field.
:rcics
– The real CIC start value of the PCT entry shown in the RCICS
field.
:rcice
– The real CIC end value of the PCT entry shown in the RCICE
field.
The PCT entry that is being removed must exist in the database. The values for the parameters of the PCT entry must be entered as shown in the rtrv-pct
output. If dashes are shown in a field or column, the field or column has no value and the parameter that corresponds to that field or column cannot be specified with the dlt-pct
command.

4.5 Configuring the Point Code and CIC Translation STP Option
This procedure is used to configure the STP option for the PCT (Point Code and CIC Translation) feature using the chg-stpopts
command with the pct
parameter. The pct
parameter has three values.
on
– The PCT feature is applied to all MSUs.off
– The PCT feature is not applied to any MSUs.lset
– The PCT feature is applied to incoming MSUs or outgoing MSUs on a linkset whosePCT
option value ison
.
The default value for the pct
parameter is off.
The value of the pct
parameter is shown in the PCT
field of the rtrv-stpopts
output. The PCT
field of the rtrv-stpopts
is shown only if a PCT quantity is enabled.

4.6 Configuring the Point Code and CIC Translation Linkset Option
This procedure is used to configure the PCT (point code and CIC translation) option for a linkset using the chg-lsopts
command with the pct
and lsn
parameters.
pct
parameter has two values.
on
– The PCT feature is applied to incoming MSUs or outgoing MSUs on a linkset.off
– The PCT feature is not applied to incoming MSUs or outgoing MSUs on a linkset.
The default value for the pct
parameter is off
.
The lsn
parameter value is the name of the linkset that is being changed. The lsn
value is shown in the LSN
column of the rtrv-ls
output.
The value of the pct
parameter of the linkset can be changed only if a PCT quantity is enabled. The pct
parameter value the linkset will effect the linkset's traffic only if the PCT
value in the rtrv-stpopts
output is lset
. The PCT
field of the rtrv-stpopts
is shown only if a PCT quantity is enabled.
The value of the pct
parameter of the linkset is shown when an individual linkset is displayed by entering the rtrv-ls:lsn=<linkset name>
command. The pct
parameter value is shown in the PCT
column.
Canceling the RTRV-LS
Command
Because the rtrv-ls
command used in this procedure can output information for a long period of time, the rtrv-ls
command can be canceled and the output to the terminal stopped. There are three ways that the rtrv-ls
command can be canceled.
- Press the
F9
function key on the keyboard at the terminal where thertrv-ls
command was entered. - Enter the
canc-cmd
without thetrm
parameter at the terminal where thertrv-ls
command was entered. - Enter the
canc-cmd:trm=<xx>
, where<xx>
is the terminal where thertrv-ls
command was entered, from another terminal other that the terminal where thertrv-ls
command was entered. To enter thecanc-cmd:trm=<xx>
command, the terminal must allow Security Administration commands to be entered from it and the user must be allowed to enter Security Administration commands. The terminal’s permissions can be verified with thertrv-secu-trm
command. The user’s permissions can be verified with thertrv-user
orrtrv-secu-user
commands.
