Asked about the TRSP-TRSP. It's the trunk conditioning.
When you test this with any other type of trunk conditioning, you'll see CRC errors (bit errors). This is because the 6th and 12th frame of SF (and 6, 12, 18, 24 frames of ESF) are used for signal supervision such as ON HOOK, OFF HOOK, etc.
The TRSP-TRSP means TRANSPARENT. In another perspective, it's the trunk conditioning you would need for data circuits going through a 1/0 DACS. The least significant bits (LSBs) on each DS0 in the frames listed above aren't modified for the signal supervision when using TRSP-TRSP.
One thing you need to make sure of: match the trunk conditioning with the circuit type, or things won't work.
