System and method for supporting higher-layer protocol messaging in an in-band modem |
| 摘要 |
Acknowledging a source terminal data message from a destination terminal in an in-band communication system is disclosed. A first synchronization sequence followed by a low layer acknowledgement message and a second synchronization sequence followed by a high layer acknowledgement message is transmitted. |

1. A method of acknowledging a source terminal data message from a destination terminal in an in-band communication system, the method comprising:
transmitting an in-band low layer acknowledgement (LLACK) signal, wherein the LLACK signal is comprised of a first synchronization sequence followed by a LLACK message; and transmitting an in-band high layer application (HLMSG) signal, wherein the HLMSG signal is comprised of a second synchronization sequence followed by a transformed HLMSG message, wherein the second synchronization sequence is different than the first synchronization sequence sufficient to distinguish the LLACK message from the transformed HLMSG message without acknowledgement identifier bits.
