isdnCIPvalue -- ISDN compatibility information profile value parameters

Synopsis

   #include <sys/types.h>
   #include <sys/scoisdn.h>
   
   typedef isdnWord_t isdnCIPvalue_t;

Description

The isdnCIPvalue parameter identifies a complete Compatibility Information Profile (CIP):

``Bearer Capability'' (BC)
``Low Layer Compatibility'' (LLC)
``High Layer Compatibility'' (HLC)

With this parameter, standard applications are not required to do complex coding and decoding of the aforementioned information elements.

Some of the CIP values only define a ``Bearer Capability'' and others define a combination of ``Bearer Capability'' and ``High Layer Compatibility''. A ``Low Layer Compatibility'' information element is not defined with the CIP and must be provided by the application if required.

The isdnCIPvalue parameter is used by the ISDN_CONNECT.ISDN_REQ(D7isdn) and ISDN_CONNECT.ISDN_IND(D7isdn) messages.

BC values

CIP values defining only ``Bearer Capability'' have these attributes (except where noted otherwise):

coding standard: ITU
transfer mode: circuit mode
information transfer rate: 64Kbps

Valid BC values for the indicated service (except where indicated, the information transfer capability corresponds to the service) are:

ISDN_CIPVAL_NONE

no predefined profile

ISDN_CIPVAL_SPEECH

speech

NOTE: The latter coding applies to ISDN with a default of A-Law coding for speech/audio. For ISDN with a default of GREEK SMALL LETTER MU

-Law coding, the corresponding values will be used

<0x04, 0x03, 0x80, 0x90, 0xA2>

NOTE: The latter coding applies to ISDN with a default of A-Law coding for speech/audio. For ISDN with a default of GREEK SMALL LETTER MU

-Law coding, the corresponding values will be used

BC/HLC values

CIP values defining a combination of ``Bearer Capability'' and ``High Layer Capability'' have these attributes (except where noted otherwise):

coding standard: ITU
interpretation: first characteristics identification is to be used
presentation: high layer protocol profile
Bearer Capability: according to corresponding BC value
