In NYC high rise not catching the signal indoor. any recommendation for antenna?

If you aren't able to get a GPS signal indoors, then an outdoor antenna may be the only option. The manufacturer of the device has some recommended options if putting something outdoors/rooftop is an option. Alternately, the TM2000B, if connected to the Internet and only needed for NTP time serving, can be setup to get its time from Peer time servers and server time that way without a GPS signal.

Does it support ptp profile g.8275.2?

Yes, it supports the Telecom profile.

What is the current requirement (amps)? What is the input voltage tolerance?

Total current draw is under an Amp. Higher draw at startup to warm up the OCXO. The input voltage regulator is tolerant of a wide range of voltages, but 9-14V should be just fine, this has not been extensively tested. Contact the manufacturer directly with specific requirements.
