Two questions:

If i use an E1 G703 for a lease line at 256k. I need to configure 2 or 4 Timesolts?

I think 4 but my ISP tell me 2.

Who is right?

I think: E1 -> 2048 with sync (32ts).

1 ts = 64k. 2ts= 128k 4ts=256 !

Second question. All G703 use NSA frame?

Thank for your answer

You would need to configure 4 timeslots

Each timeslot will give you 64K and hence you would require 4 timeslots

Controller e1 0/0

channel-group 0 timeslots 1-4

I didn't clearly understood your 2nd question

HTH, rate if it does

For the second question, I think like you !! Provider send me to configure frame NSA + CRC4.

Crc4 is not a problem i can configure that. But for the NSA, i never see that. What is it? Convertion for N= ? S= ? A= ?

But thank for all your answer

NSA (Non Service Affecting) is a minor alarm frame that can be sent by T1/E1. I don't think the router uses it and I've never seen it used in practice.
