4.6.2 Configuring SPC Service
I.
Overview of SPC service
Without presence of an MGC, the SPC can be established by
the commands issued from the command line terminal or NMS, in
order to set up an SPC between the ports of two IAD108s, or
between different ports of the same IAD108. In SPC, the voice
channels are fixed and dedicated, so that the service demands and
communication quality of important users can be guaranteed.
There are two kinds of SPCs:
z
IP SPC, which is established between the IAD108 and
another IAD.
z
Internal SPC, which is established between the ports of the
same IAD108.
On the same user port, you can configure either the ordinary
access user service or the SPC service. In case both services are
configured on the same user port, the SPC service will have a higher
priority. To enable the ordinary user service on this port, you must
release or delete the SPC service data on this port.
