Bandwidth Provisioning

Intra-Cluster Communications Signaling (ICCS)
Total Bandwidth (Mbps) = ((Total BHCA) / 10,000)
[2.25 + (0.006 Delay)],
where Delay = Round-trip-time delay in msec
This is the bandwidth required between each Unified CM subscriber that is connected to voice
gateways, agent phones, and Agent PGs.

Database and other communications
1.544 Mbps for each subscriber remote from the publisher
The BHCA value to use for the ICCS formulae above is the total BHCA for all calls coming into the
contact center.

These bandwidth requirements assume proper design and deployment based on the recommendations
contained throughout this document. Inefficient design (for example, if ingress calls to Site 1 are treated
in Site 2) will cause additional intra-cluster communications, possibly exceeding the defined bandwidth
requirements.

Bandwidth Requirements for Gateway PG to System PG
This section provides some basic guidelines for provisioning bandwidth for the connection between the
gateway PG and the system PG.

Bandwidth Requirements for Unified CCE Gateway PG to Central Controller
No special considerations are necessary for the PG-to-CC connection over other TDM PGs.
If agent reporting is not used, then the Enable Agent Reporting checkbox in the Agent distribution tab
of the PG explorer should be unchecked to avoid sending unnecessary data over the link. For more
