3.3.2. MTP Configuration

The only time where some special MTP configuration is required is when some SS7 link is to be routed over the CT Bus or SCbus, from an Intel® Dialogic network interface card (DTI) to an Intel® NetStructure™ SS7 board. The MTP_LINK lines that correspond to such links must be preceded by a comment having the following syntax:

    * [link src=<device_name>] 
    MTP_LINK ...  

where <device_name> is the Intel® Dialogic DTI time slot device name (for example, dtiB1T1, dtiB1T31) on which the SS7 signaling link is present.

Note: For E-1 lines, physical time slot 16 on a DTI board is usually reserved for signaling, but is named dtiB1T31 (because physical time slot 17 is named dtiB1T16).

Additionally, for links that are routed over the CT Bus, for the Intel® NetStructure™ SS7 ISA (PCCS6) board the stream parameter of the MTP_LINK command must always be set to 0x12 and the timeslot parameter must be set in such a way that the same time slot of stream 0x12 is not used for more than one signaling link. Normally, you would start with time slot 1 for the first link and increase the number for every additional link routed over the CT Bus. For example, the following lines define two signaling links that must be routed to/from time slots 16 of dtiB1 and dtiB2 boards.

    * [link src=dtiB1T31]               stream      ts
    MTP_LINK 0  0  0  0  0  0   0x12  0x01  0x06 
    * [link src=dtiB2T31] 
    MTP_LINK 1  0  1  1  0  1   0x12  0x02  0x06  

For Intel® NetStructure™ SS7 CompactPCI and PCI boards, the stream parameter should be set to 0x83, and the timeslot parameter should be set to 0 for the first link, 1 for the second link, 2 for the third link and 3 for the fourth link. The other parameters should be set to the correct values for the link being configured.

    * [link src=dtiB1T31]               stream        ts
    MTP_LINK 0  0  0  0  0  0   0x83    0  0x06 
    * [link src=dtiB2T31] 
    MTP_LINK 1  1  0  0  0  1   0x83    1  0x06
