IOSS Provisioning Component Architecture
Figure 2-6 depicts the proposed Provisioning Management Solution for OPT networks, as applied to an H.323-based global long-distance network. The key component is the Cisco Packet Telephony Center (Cisco PTC), which provides for overall configuration management of the OPT network and realizes the virtual entities as discussed. A module within Cisco PTC, called Cisco VRC, provides for H.323 dial-plan management. Cisco PTC enables context sensitive launching of other management tools, that is, where it makes sense from a navigation standpoint, for an integrated user experience. A pre-integrated application is the Voice Services Provisioning Tool (VSPT), which can be used to bulk configure the Cisco PSTN Gateway (PGW) 2200. VSPT is used for initial configuration of the PGW 2200 with SS7 components such as point codes, link sets, SS7 paths and routes, SS7 subsystems, and ethernet cards and interfaces, which are prerequisites to Cisco PTC configuring RLMs and nailed trunks in the PGW 2200.
To communicate with underlying network devices, Cisco PTC makes use of underlying EMSs, such as the Cisco MGC Node Manager (CMNM) for the Cisco PGW 2200. EMSs can also be launched as auxiliary tools by the user to drill down into the device or obtain a graphical device view. In cases where an EMS is not readily available, Cisco PTC can also interface to devices directly or, as in the case of Cisco IOS devices, utilize the Cisco CNS Intelligence Engine (Cisco CNS IE2100). It should be noted that the applicability of the Cisco PTC and its fundamental concepts goes beyond any particular solution and is not limited to support only certain device types; it is expected that essentially any Open Packet Telephony (OPT) Solution can be added.
The network elements that can be provisioned with the pictured applications include:
1.Virtual zones of IOS based H.323 voice gateways and gatekeepers including:
a.AS5000 series.
b.c2600, c3600, c7200 series.
2.Virtual gateway node elements including:
a.Signaling Link Terminals.
b.PGW 2200 Signaling Controller.
c.Catalyst switches.
d.AS5000 series voice gateways.
