Maximum number of TGM550s 250

controlled by an S8500 or S8700-series Server

Maximum number of TGM550s	5
controlled by an S8400 Server

Maximum number of TGM550s 49

controlled by an S8300 Server in a G350 or G700

This number also applies if a combination of Avaya G700 Media Gateways, Avaya G250 Media Gateways, and G350 Media Gateways are controlled by the same server.

This capacity is 50 if a combination of Avaya G700 Media Gateways, Avaya G250 Media Gateways, and G350 Media Gateways are also controlled by the same server. The S8300 must reside in a G700 or G350. Therefore, the maximum of 50 H.248 gateways supported by the S8300 means that only 49 of the 50 could be IG550s.
