Hi Xihua,

The G.872 does talk about media channel supporting multiple OCH-Ps.

Thanks,

Hi Iftekhar,

If you refer to current "in force" G.709 or G.872, you can't get any describtion on an OCh-P is supported by multiple network media channels. This is what I mean.

Hi,

Regarding OCh-P, thee text is referring to the ¡°in force¡± ITU doc namely,  G.872, and requesting clarification from the ITU experts. What do you mean it is not defined by ITU?

Thanks,
Iftekhar

Hi All,

I have a few minor changes to draft text.
The relationship between optical tributary signal from Q6 and network media channel from Q12 is 1 to 1.
ITU-T hasn't reach aggreement to use terminology OCh-P which is supported by multiple medial channels. I suggest we don't need to  mention this.
We should only mention when this requirement will be documented in ITU-T Recommendation. This requirement may be described as "An OTUCn is supported by multiple network media channels. These NMCs must be co-routed. They must be recoveried and cross-connected  at the same time."

Hola Oscar and Ramon.
