Fiber PNC with Remote PNs DPT Considerations

Last Updated : Oct 30, 2012 |

Fiber PNC refers to a Center-Stage Switch, ATM-PNC, DS1C-PN. Please note the following:

  • Customers wanting DPT for Survivable Core Server-controlled Port Networks (PNs) must migrate those PNs from Fiber-PNC to IP-PNC. Fiber-connected cabinets must be in Network Region 1.

  • Fiber-PNC users can reach disconnected users in other Network Regions through DPT.

  • IP-PNC/GW can only initiate DPT calls to the fiber-PNC fragment that contains the trunks associated with the IGAR LDN.

  • Users connected through Fiber-PNC cannot use DPT if another fiber PN fails over to different Survivable Core Server. This is because DPT is not triggered within same Network Region.
