Xenon Switching System
The Xenon Switching System is a digital switch supporting T-S-T switching. It can connect with Subscriber Access Networks (AN) with the V5.2 protocol. On the network side it connects with other switches using the SS7 (Signaling System #7). All the connections are implemented with standard E1 Digital trunks.
The design and development of this switching system is covered in the following sections:
