It depends on the amp you are using.  I believe if you're using the 87A or the 
89, whenever PIN diode switching is used, then you need to use the Y-cable 
described on the Alpha web site.  If you're' using the '91b or the '99 or other 
vacuum relay switched Alpha, then you can use the TX-En / TX-out keying loop 
just as you would a TT amp.  That's how I had my '99 wired to the Omni VI+, and 
it's how I'm currently wired with my Orion to the '99.

BTW, Alpha is offering the last of their 87A's with gold plated coils, silver 
plated capacitors, and calling it the Alpha 87A Omega as a limited offering 
before their new replacement amp comes out.  It was described to me as one that 
will be better optimized for manufacture, and will most likely have new 
features.  They were not talking much about it when I asked.  FWIW.
