ITU-T H.324 Annex H (11/2000)

Mobile multilink operation

This annex defines the operation of H.324 over up to 8 independent physical connections, aggregated together according to the mobile multilink layer defined in this annex to provide a higher total bit rate. These connections are error prone mobile channels as defined in Annex C/H.324 all having the same transmission rate. The difference between Annex H and Annex F is that Annex H is primarily intended to be used on error prone connections by not using HDLC framing and with less flexibility in terms of the number, the bit rate, and the delay differences of the channels involved in the aggregation than Annex F in order to work on mobile connections. Annex H is not intended to be a replacement of Annex F on connections with very low bit error rates.
