| Question ID 13002 | How many signaling bits are there in each T1 time slot using channel associated signaling
with Super Frame?
|
| Option A | 1
|
| Option B | 2
|
| Option C | 4
|
| Option D | 8
|
| Option E | 12
|
| Correct Answer | B |
Explanation Explanation: Each T1 CAS has 24 channels that can transmit 8 bits per channel each. This gives us a total of 192 bits. The T1 has one additional bit for framing, bringing the total to 193 bits. Two types of line coding can be used on a T1 CAS. The first type of line coding is called Super Frame (SF). This is an older and less - efficient type of framing. Super Frame bundles 12 of these 193 - bit frames together for transport. It then uses the even numbered frames as signaling bits. The T1 CAS signaling then looks at every sixth frame for signaling information. This comes out to be 2 bits that are referred to as the A and B bits, which reside in frames 6 and 12.
