Network Tests

Network tests control the activation of loopbacks and the initia- tion of data test patterns.

Network tests are run on the Network Interface (NI). You can select three different test configurations to determine the type of loopback and the pattern to run. Test results display in the LCD window.

Executing NETWORK TESTS will disrupt normal data flow unless only TST DS0S are selected for testing.

Loopback Tests

A number of different loopbacks can be invoked locally from the front panel, by T-Watch commands, or remotely by using special in-band codes (AT&T D4 network loop-up and loop- down codes). Additionally, the loopbacks can be remotely con- trolled by means of out-of-band commands by the T1 ESF FDL or from T-WATCH Pro by a modem connection.

Network Interface Loopbacks

Network interface loopbacks (see Figure 7-2 on page 7-4) affect the entire T1 data stream. There are two types of network loop- backs, LINE LOOPBACK and PAYLOAD LOOPBACK.

Line Loopback

Line loopback loops all of the received data back toward the network. The transmitted data is the identical line code that was received, including any bipolar violations or framing errors.

Payload Loopback

Payload loopback is similar to line loopback, except that the framing is extracted from the received data and then regener- ated for the transmitted data.
