Anyone know of a solution that doesn't require an external antenna, is NEBS compliant, and has T1-type outputs for me 
to hook into my Metaswitch gear?

Hello, 
As other have commented before, it looks you need an outdoor antenna, however, reading the specs it says: 


"The built in high sensitivity GPS receiver is able to lock multiple satellites from within multiple buildings or from 
a window location , eliminating the requirement that an outdoor antenna be installed ." 



Weird. 


Alejandro,

hey there Nanog, 


I am trying to buy a GPS based NTP server like this one 


https://timemachinescorp.com/product/gps-time-server-tm1000a/ 



but I will be placing this inside a data center, do these need an actual view of a sky to be able to get signal or will 
they work fine inside a data center building? if you have any other hardware requirements to be able to provide stable 
time service for hundreds of customers, please let me know.
