E1 Analyzer
Setting Up Delay Test Mode
Use this test mode to have the test set measure the round trip delay of an E1 circuit.
It is necessary to have a loop condition at the far end during this test. The best
accuracy is obtained when a hard loop exists at the far end. Be aware that devices
placed in loopback may add additional delay. During this mode, a pattern consisting
of a zero inserted into a string of ones is transmitted and analyzed to determine the
delay in the path. The selected test pattern is sent as filler during the calculation
interval.
