IP Payload Switching
4.7 IP Payload Switching
Introduction
IP payload switching optimizes communication between LAN-based IP workpoint clients.
In HiPath 3000 V1.2 and lower, two B-channels (with two DSP resources) in the HiPath
HG 1500 and HiPath 3000/5000-internal switching network were seized for internal network
calls.
In HiPath 3000/5000 V3.0 and later, VoIP voice data (payload) is transferred directly between
two IP workpoint clients in the network. When this happens, both IP workpoint clients have full
access to all system features.
Payload switching is also implemented for IP networking (PBX routing).
By ceasing to use B-channels, we have managed to preserve HG 1500 resources and facilitate
a higher volume of network-internal call traffic.
A B-channel is still required on the HG 1500 for connections to the following stations and lines:
● U P0/E stations (optiset E, optiPoint 500)
● Analog stations
● ISDN stations
● Trunks and tie lines (MSI, S 0 , S 2M )
Example: a consultation call to an optiPoint 500 telephone is set up during an existing connection
between two IP workpoint clients. A HG 1500 B-channel is necessary for this consultation
call.
In the case of conferences, the number of B channels seized corresponds to the number of stations
and IP workpoint clients involved.
A HG 1500 DSP resource is permanently reserved for playing music-on-hold.
Example: a license was acquired for two B channels and six clients. Six optiPoint 400 standards
were logged on. The following scenario is possible in this case: two stations can conduct an
external call, while two stations are listening to Music on Hold and two stations are talking to
each other.
