hi,

It's possible connect more than one ePTP Slave in one ePTP master ? or in PTP TDD ?

Hi Alex,

PTP abbreviation you see in mode names ePTP and PTP TDD  means Point-to-Point.

Only one SM in ePTP Slave mode can be registered on AP in ePTP Master mode and only one SM in TDD mode can be registered on AP in TDD PTP mode.

Thank you.

Hi Fedor;

Just for further information on the ePTP mode. 

  1. If an AP that is servicing a sector of say 10 clients/SMs, then one of those SMs can be set to ePTP mode and connect to the same AP?
  2. If so, then this basically means that the AP-SM link will operate with better performance (latency, throughput) or give some advantages on how/why this setup will be practical.
  3. If the AP is set to be GPS Synch, will this still work?
  4. If the AP is set to use ePTP mode, (GPS synch or not), will this still operate as an Access Point (AP), i.e. service all SMs in the sector, but allow one SM to connect to it in ePTP mode?
  5. Or, are the ePTP modes both on the AP and SM, strictly for making and establishing the e ePMP series to be a pure PtP system, without the capability of having more than one device associated to it?

Regards.

Hi Lincs_Chel,

SM in ePTP Slave mode can be registered only on AP in ePTP Master mode.

AP in ePTP Master mode cannot hold more than one SM.

GPS sync is supported only in TDD mode.

Thank you.

Hi Fedor;

Thanks very much for explaining this further. 

Sometimes, it appears from the documentation and users comments that you can have an ePTP slave or ePTP mode on a single SM in the same sector just to satisfy a low-latency customer or for a micro-POP or micro-cell setup/application.  While at the same time having regular SMs associated to the same AP.

Maybe a warning or popup note on the AP that says that this is exclusively for establishing a Point-to-Point mode may help.  Like when you hover the mouse of the various mode selections may help.
