Gateway Channels (DSP Channels)

Gateway connections are required for connections to TDM workpoint clients and lines. A gate-
way channel is required on the HiPath HG 1500 board for each gateway connection. TDM work-
point clients and trunks include, for example
U stations (optiset E, optiPoint 500)
●
P0/E
CMI stations
●
analog stations
●
ISDN stations
●
trunk and tie lines (MSI, S
●
Examples: a consultation call to an optiPoint 500 telephone is set up during an existing connec-
tion between two IP workpoint clients. A HG 1500 board gateway channel is necessary for the
consultation call.
An IP workpoint client seizes a trunk. A HG 1500 board is required for this trunk.
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).
