Bandwidth Control
[Series 3100 software required]
General Description
This feature allows to assign an available bandwidth threshold for VoIP traffic within a Location and be-
tween Locations, and to restrict outgoing/incoming calls when the VoIP traffic exceeds the threshold.
The Location is a group of VoIP devices (IP Enabled D
trunks]), which the same VoIP communications parameters such as codec selection list and ToS field value
are assigned.
When the VoIP traffic over CCIS exceeds the threshold, the call can be routed to legacy trunks (TDM net-
work).
When exceeding the threshold, the system can store fault information and provide external alarm indica-
tion.
Station Application
Not applicable
Service Conditions
1. Two kinds of threshold can be assigned on a Location-to-Location basis by system programming.
Limit Threshold
Warning Threshold: This threshold should be assigned lower than the Limit Threshold, and can be
2. Each threshold can be assigned on a Location-to-Location basis.
3. Maximum 65534 Kbps can be assigned for each threshold on a 1 Kbps increment. If no data is as-
signed, 100 Mbps is assigned (default data).
4. The following parameters can be recorded as peg count on a Location-to-Location basis.
a. The number exceeding the Limit Threshold
b. The number exceeding the Warning Threshold
c. Maximum bandwidth actually used
d. The bandwidth currently used
5. The bandwidth managed by this feature is that of voice packets for Peer-to-Peer connections only.
The data packets for control signals of IP Enabled D
feature. The bandwidth of the voice packets for each call is defined by the combination of voice en-
coding type and payload size as follows.

When the traffic exceeds this threshold, the later calls are restricted within
that Location or between those Locations.
In case of CCIS calls over IP network, the calls can be routed to the legacy
trunks (TDM network).
