-- FurherSpecOfTypeOfInterception Type

FurtherSpecOfTypeOfInterception ::= BIT STRING {
	iRI (0),
	cC (1),
	stereo (2),	-- Default: mono
	optionA (3)	-- Default: Option B

--  Explanation: 	iRI and cC provide the information, whether IRI and CC are requested. 
-- 	Stereo indicates indicates, whether the cC needs to be delivered in stereo or mono mode
--	optionA indicates, that Option A shall be used, where option A and B exist.

-- Numbers from 0 to 1000 shall be allocated by a standardization body
-- Numbers from 1001 to 9999 shall be allocated by a national regulatory agencies
-- Numbers above 10000 shall be mutually agreeable between operators

-- Explanation:	This type identifies the type of triggerinformation, which is send.

-- TriggerInformation Type

-- This parameter is used to pass information concerning the target identification. It is assumed that
-- the receiving side is able to decide autonomously if the LI function has to be started or not.
