Note:
The data packet that the MGC sends to the IAD108 contains the ringing type
parameter (whose value is the same as that of
mgcpara
), by which the IAD108
searches in the table of ringing mapping records, finds the matching
mgcpara
and
then gets the corresponding ringing types of
cadencering
and
initialring
.
Take Hong Kong as an example, and add a ringing mapping
record. Correspond the ringing type parameter 22 of MGC with the
ringing types of IAD108, and adopt the Hong Kong ringing type 2 as
the cadence ringing tone, and Hong Kong ringing type 18 as the initial
ringing tone. In this way, when the MGC sends the ringing type
parameter 22 to the IAD108, the IAD108 will use these two kinds of
ringing type. The operation is as follows:
IAD2000(config)#
mgringmode add 22 2 18
IAD2000(config)#
5.1.2 Configuring PSTN Port Attribute
The PSTN port attributes include: the volume which can be sent
and received by the PSTN access user, whether pulse dialing is
permitted at the PSTN port, and whether to provide polarity reversal
charging at the PSTN port.

Configuring Polarity Reversal Charging
Polarity reversal charging is a way to realize “immediate
charging” of the access user. The charging terminal (for example, user
charging phone) with this function has charging data itself, so only the
start and end time of the conversation is needed. The IAD108
