This is from an email list I’m on, and I realized I knew each acronym – and it made sense!
Can a SDI/DCH (ntak02ba) card be used as a programable d channel for a DTI card? If not what is the actual purpose of the SDI/DCH card? I need to be able to set the IFC type on the d channel to ISGF as necessary to interface with cisco and have QSIG work. On systems with the DTI T1 card the d channel daughterboard is not capable of being set to that type. (receive some sch error message that says isgf can only be set for card type msdl..or something close to that) These systems are all pre 24.x so a TMDI card is not an option. Even though Nortel doesn't support the msdl card anymore, could the msdl card be used in conjuction with DTI to get at PRI that works with QSIG?
