Signaling Point Code

I don?t know the convention of defining Signaling Point Codes. I know there is a decimal representation of SPC like OPC-1004, DPC-3345. There is another format of representing SPC, it is binary format (8-8-8). I want to know the details about the conventions of representing point code along with the conversion process of each.

I?ll be glad if anyone helps me or provide some reference.

Re: Signaling Point Code

There are 4 types of point codes in use:

1.
ANSI point codes are divided into three parts:
NetworkIndicator(8 bit)1 ? NetworkCluster(8 bit) - NetworkClusterMember(8 bit)
example: 240-012-140

2.
ITU International point codes are divided into three parts:
Zone(3 bits) - Area(8 bits) - ID(3 bits)
example: 04-208-06

3.
ITU National Point Codes have two possible values:
NNNNN or M1-M2-M3-M4
where:

NNNNN = A number in the range 0-16383 (14 bits)
M1 = 0-7 (3 bits)
M2 = 0-15 (4 bits)
M3 = 0-15 (4 bits)
M4 = 0-7 (3 bits)

example: 15045  or  003-010-012-005

4.
ITU National 24 bit point codes are divided into three parts:
Main Signaling Area(8 bits) ? Sub Signaling Area(8 bits) ? Signaling Point(8 bits)
example: 140-123- 028

If you would like to convert your poincodes try to use http://jhartman.webd.pl/pc/ - that's online converter.
