I'm a technical analyst for First Data, in the credit card software dept (or 'tech desk'). Basically, I field questions from developers who are trying to integrate their own interfaces into the engine we provide, but I also get cases assigned to me from the lower level tech support personnel. Basically, if something pops up that the lower level reps can't figure out or fix, it gets escalated to my dept and we figure it out.
The one case I got today is a modem issue, but the lower level rep already rebuilt all the configuration files to eliminate the possibility of corruption and has done everything they can to get the modem to talk. I'm not entirley sure why this case got escalated, as the first person covered everything that can be covered from the software angle. Basically, I just need to call this person and tell him he either needs an onsite technician to look at the machine or he needs to just buy a new modem.
