Regular Operations
Table 3-13 lists the preconditions that you must establish for the component before you can perform any
modification or deletion as part of dynamic reconfiguration. There are no preconditions for adding
components as part of dynamic reconfiguration.
For example, to change the settings for a DPC or remove it altogether, you must first set the service state
of the DPC to OOS, before attempting to make changes. If you do not set the service state to OOS, your
dynamic reconfiguration request is rejected with an error message.
During dynamic reconfiguration, the system goes through two phases. First, it validates the service states
of all objects being changed. If any error is encountered, no reconfiguration takes place on any of the
objects. Error messages indicate which components are in error. The format of the error message is
“Component’s MML name, process rejecting change, reason for rejecting the change, remedy.”
If no errors are encountered during the validation phase, the update phase proceeds. In this phase, all of
the processes load the new configuration data. At the beginning of the update phase, the system displays
an SNMP alarm to indicate that the update is starting. At the end of the update phase, the alarm clears,
and if MML initiated commit or deploy, the system returns the MML response.
To change the current configuration of a component using dynamic reconfiguration, you can use only
the provisioning tools that are provided with the Cisco PGW 2200 Softswitch, MML provisioning
commands, or an SNMP provisioning agent (such as the Cisco Voice Services Provisioning Tool (Cisco
VSPT)).
Table 3-13 Dynamic Reconfiguration Preconditions
Component Preconditions
CICs Call state of the CIC must be IDLE (see the “Verifying CIC
States” section on page 3-15) and the service state of the
associated DPC must be set to OOS (see the “Setting the
Service State of a Signaling Service” section on page 6-103).
or
Block type for the CIC must be set to locally blocked (see the
“Blocking CICs” section on page 3-55) and the associated
media gateway span and time slot must be set to OOS (see the
documentation for the media gateway).
Point codes (DPC, OPC, or APC) and
SS7 routes
Service state of the point code and SS7 route must be set to
OOS (see the “Setting the Service State of a Signaling
Service” section on page 6-103).
Signaling links (TDM, ATM, or SS7) Service state of the signaling link must be set to OOS (see the
“Setting the Service State of a C7/SS7 Link or Linkset”
section on page 6-105).
Signaling services Service state of the signaling service must be set to OOS (see
the “Setting the Service State of an SS7 Signaling Service”
section on page 6-104).
SS7 subsystems Service state of the subsystems and routes must be set to OOS
(see the “Setting the Service State of a Local Subsystem
Number” section on page 6-107).
Trunk groups
Component properties (linksets,
signaling services, and trunk groups)
None.
