(H.245) conference member size limitation ?

in H.245 Asn

TerminalLabel ::=SEQUENCE { mcuNumber McuNumber, terminalNumber TerminalNumber, ... }

McuNumber ::=INTEGER(0..192) TerminalNumber ::=INTEGER(0..192)

It seems that there is limitation of conference member size in one mcu to 193 members.

Am I right?

I think that in the conference type of broadcast ( one speaks and others listen ) the limitation is a little severe..
