The signalling tester monitors the communication between MS and BS for efficient trouble shooting. It acts as a base station simulator as it supports L1 and L2 sequences by being able to edit the L3 protocol sequence (which controls L1 and L2). It gives information by monitoring the communication between the MS and signalling tester. The MD8480B contains 3 solutions. It is able to confirm modulation and demodulation parts of the MS, confirm the protocol sequence between MS and BS and even simulate applications. It can simulate the following applications: AMR voice test, user data test, IP packet test, PPP packet test, ISDN test and communications between two MS. This signalling tester also has the ISDN option. It is in excellent condition and comes with a variety of accessories including a phone line (RJ45), test phone, BNC test cable, power cable, DB9 cable and other wires. See pictures for exact items.
