Testing and Fault Mitigation

---

The complexity of T1 testing certainly parallels or possibly exceeds that of RF tests at a cell site. Shadowing efforts and customer expression have shown that most cell site technicians reduce the complexities of backhaul T1 testing down into a series of well-defined steps. These tests are often not comprehensive, but are often sufficient to determine the continuity of a T1 circuit with a high degree of confidence. The test sequence is often developed by an experienced technician and is determined by finding the shortest path to an adequate measurement on a particular piece of readily available equipment. T1 testing often involves one technician on each end of a circuit. In the case of wireless, the technician at the switch end, very experienced at backhaul testing, is often working with a field technician who has a broader-based set of knowledge and is often less experienced in backhaul testing. The switch technician quickly develops a test procedure that involves the smallest number of verbal instructions to the field technician.
