The OTM overhead signal (OOS) consists of the OTS, OMS and OCh overhead. The format, structure and bit rate of the OOS is not defined in this Recommendation. The OOS is transported via an OSC.
Depending on an operator's logical management overlay network design, general management communications may also be transported within the OOS. Therefore, the OOS for some applications may also transport general management communications. General management communications may include signalling, voice/voiceband communications, software download, operator-specific communications, etc
OTM开销信号(OOS)由OTS、OMS和OCh开销组成。OOS的形式、结构和比特率不在本建议中定义。OOS通过OSC传送。
与涉及网络设计的操作人员逻辑管理有关的,通用管理通信可以在OOS中传送。所以,一些应用的OOS也可以传送通用管理通信。通用管理通信可能包括信令、语音/语音频带通信、软件下载、操作者特定通信等。
