I have a need for an FXS ATA that can withstand relatively high ambient temperature ranges. The issue I face is a need to accommodate analog auto-dialers that relay pre-recorded voice announcements. The dialers are located in remote outdoor, weatherproof enclosures (NEMA4 or IP55) and there are no nearby structures that offer any relief or ability of being able to locate the ATA. The ATAs will need to be located in similar cabinetry, but if I cannot find a more suitable model, likely in NEMA-3R rated encloures with air exchange capability in order to keep the ambient temperatures manageable. The dialer equipment is rated for 140F, whereas most of the ATAs I have been able to source are rated from 104F or 113F. I have seen a couple from companies based in India and S. Korea that report 122F capability, but I seek something even higher if available. I am hoping that some on the forum might know of a make/model that is more robust.
