Hi All,
I'm taking ICND2 this coming Nov.11 (wish me luck). I do have a few questions to better understand some topics covered in the exam and I would really appreciated if some of you guys could simplify it for me.
1. What does clock rate command do?
2. DS1/T1 has 24 DS0s w/c equals to 1 channel w/c equals to 1voice/data line. Does it mean that if I have DS1/T1, I will be able to receive 24 incoming calls and/or 24 outgoing calls simultaneously?
Hope someone can elaborate that to me in a simplified term. Much appreciated guys.:D

The clock rate command controls the timing for serial connections. This simulates the timing that the ISP would set on the line. This command is usually only utilized in a lab scenario to replicate WAN connections. As for your second question I am not sure. -

It depends on the codec used. For G.711 it's 64kbps, but it's only 8 kbps for G.729a (plus overhead). It's outside of ICND2 scope I believe.
