How do I setup DCOSS for a simple loopback mode for testing?
Configuring DCOSS for loopback mode differs slightly depending on the protocol being used. First, connect a crossover RJ-45 cable (the TX is connected to the RX and the RX is connected to the TX) to the DCOSS; one end of the cable to trunk 0, the other end of the cable to trunk 1 (this may differ depending on which DCOSS trunks you wish to loopback). CAS Protocols. The two trunks being placed in a loopback configuration must be configured with the same protocol and protocol configuration (using the DCOSS Protocol Configuration screen). After opening the trunks, use the DCOSS Manual Call Generation (1) screen to place a call on a desired timeslot. Use the DCOSS Manual Call Generation (2) screen to answer the call on the incoming timeslot (the opposite trunk). PRI ISDN Protocols. The two trunks being placed in a loopback configuration must be configured with the same protocol and protocol configuration (using the DCOSS Protocol Configuration screen). One side of the loopback must be conf
