VISM Features
MGX 8000 Series Implementation Enhancements
The following enhancements are supported with this release with additional implementation of your
MGX 8000 Series switch:
• Additional VBR Enhancements
• Expanded Clock Source Selection
• Private Network-to-Network Interface Priority Routing
• Additional SPVC Connection Management Capabilities
• 192 T1/248 E1 DS0 Support with High Complexity Codecs on VISM-PR

Additional VBR Enhancements
Setting connections between a VISM-PR card and an RPM-PR card in your MGX 8000 Series switch
chassis requires you to use the new VBR (NRT) 3 connection type. Use the modified addcon or cnfcon
commands to configure this connection type. In addition, the following new connection service types can
be configured with the modified commands in this release:
• VBR (RT) 2
• VBR (RT) 3
• VBR (NRT) 2
Expanded Clock Source Selection
An expanded clock source selection allows you to configure any VISM-PR card line as the clock source.
You cannot delete a VISM-PR line that is configured as the clock source; you must configure a different
line as the clock source and then you can delete the original clock source line. The previously released
CLI commands allow you to use this feature.
Note This feature requires you to use a PXM1E or PXM45 in your MGX 8000 Series switch chassis.
Private Network-to-Network Interface Priority Routing
The Private Network-to-Network Interface (PNNI) routing priority feature allows you to specify
connections with a routing priority. The PNNI controller uses your configuration selections to route the
higher priority connections before routing the lower priority connections. Use the cnfpncon command
to configure a routing priority for a specified connection.
Note This feature requires you to use a PXM1E or PXM45 in your MGX 8000 Series switch chassis.
