122 Bandwidth Management Support for Network Wide Virtual Office
The customer can check the value of the Current Zone for IP sets using
LD 20, PRT command - as this value is not configurable, no changes are
made to LD 11.
Operating parameters
The following are operating parameters for this feature:
• Only IP Phones with the "IP Client cookies" feature enabled are
supported
• The correct BWM calculation for a Virtual Office (VO) IP Phone is
possible only within the home Customer network (when all the systems
are configured with the same VPNI number).
• The maximum number of Bandwidth Zones that can be configured on the
Call Servers within the home customer network is limited to 255 (1-255).
• The interaction between CS 1000 Release 5.0 and the previous releases
is not supported. Therefore, the correct bandwidth calculation will not
be provided if a remote VO login is performed from a CS 1000 with a
software release that is earlier than CS 1000 Release 5.0. In this case
the earlier release’s bandwidth calculation method is used.
• If two or more Call Servers have the same VPNI and Bandwidth Zone
configured, the usage in this zone can’t be synchronized between these
Call Servers.
• The feature supports only one customer. If more than one customer is
configured, the customer with the lowest customer number is supported.
Assumptions
The following configuration is used:
• Bandwidth zones are allocated on a Network-wide basis.
• All zones in the network are configured on all the Call Servers.
• All Call Servers within the network will have the identical copy of the
zone table and each individual zone policy.
• The VPNI number will be configured as the same for all Call Servers
within the network.
• Call Servers that belong to different networks will have different VPNI
numbers. Each network has its individual VPNI numbers.
• The identical copy of the zone table within the network should be
configured manually unless a synchronization mechanism is introduced.
