Gateway channels (DSP channels)
Connections from IP workpoint clients/lines to TDM workpoint clients/lines
Gateway connections are required for connections from IP to TDM workpoint clients and lines.
A gateway channel is required on the HG 1500 board for each gateway connection.
TDM workpoint clients/lines are:
U
stations (optiPoint 500)
●
P0/E
CMI stations
●
analog stations
●
ISDN stations
●
trunk and tie lines (MSI, S
●
Examples for assigning a gateway channel on the HG 1500:
A consultation call to a TDM workpoint client is set up during an existing connection be-
●
tween two IP workpoint clients.
An IP workpoint client seizes a trunk.
●
Connections between TDM workpoint clients/lines
Connections between TDM workpoint clients/lines do not require DSP channels. The commu-
nication system automatically detects that no DSP channels are required.
Conferences
In the case of conferences, the number of gateway channels seized corresponds to the number
of stations and IP workpoint clients involved.
Channels required for gateway connections
The following table shows the number of gateway channels (HG 1500 boards) necessary
based on the existing IP workpoint clients.
The calculation of the values is based on the following assumptions:
A station spends 10 % of its working time in call status.
●
The average time per call is three minutes.
●
The availability loss is limited to 1.2 %.
●
Provisions should be made for more gateway channels (HG 1500 boards) in high traffic volume
environments (for example, call centers).
