1751/1760 Very Confising Info on CCO re PVDMs

http://www.cisco.com/en/US/partner/products/hw/routers/ps221/prod_configuration_guide09186a0080106d1c.html

it says regarding codec complexity:

high—Specifies two voice channels encoded in the following formats:

G.711a-law, G.711u-law, G.723 Annex A(r5.3),

G.723 Annex A(r6.3), G.723(r5.3), G.723(r6.3),

G.726(r16), G.726(r24), G.726(r32), G.728

G.729(br8), G.729(r8).

medium—Specifies four voice channels encoded in the following formats:

G.711a-law, G.711u-law, G.726(r16),

G.726(r24), G.726(r32), G.729(br8), G.729(r8).

Configuring the codec complexity as medium, blocks the G.723(8) and G.728 voice calls on the voice-card.

So is g.711 and g.729br8 ulaw high or low? how can it be both?

Re: 1751/1760 Very Confising Info on CCO re PVDMs

You have an option to run medium complexity codecs as high. So while technically speaking G.711 is by default a medium complexity codec, you can run it as a high complexity codec if you wish.
