Hello everyone, I want to share with you about What is PRA link. I hope you find it useful.
A type of common channel signaling link that usually occupies the 16th timeslot of an E1 link. The PRA link uses the digital subscriber signaling No.1 (DSS1) signaling. The DSS1 signaling is a type of non-peer-to-peer user signaling. Before a PRA link is set up, the two ends of the link detect the network identifications (NIDs) of each other. The PRA link can be set up only when the NID of one end indicates the network side and the NID of the other end indicates the user side.
That's all, I welcome everyone to leave a message and exchange in the comment area!
