Translational cross-connect (TCC) is a switching concept that allows you to establish interconnections between a variety of Layer 2 protocols or circuits. It is similar to its predecessor, circuit cross-connect (CCC). However, while CCC requires the same Layer 2 encapsulations on both sides of a Juniper Networks router (such as PPP-to-PPP or Frame Relay-to-Frame Relay), TCC lets a network administrator connect different types of Layer 2 protocols interchangeably. With TCC, combinations such as PPP-to-ATM and Ethernet-to-Frame Relay cross-connections are possible. Also, TCC can be used to create Layer 2.5 VPNs and Layer 2.5 circuits.
