Tributary And Optical Tests For Vtbm Rings; How To Use This Chapter - Nortel SONET AccessNode Manual

Tributary and optical tests for VTBM
rings
Use this chapter to test DS1, DS3, and optical equipment at an AccessNode
(system) network element (NE) Access Bandwidth Manager (ABM) shelf.
These procedures cover local in-bay tests on equipment located at a single NE,
and can form the basis for customer acceptance tests. Unless otherwise noted,
the tests can be performed by one technician. End-to-end testing (between two
NEs) of optical and digital equipment is described in System Testing
Procedures, 323-3001-222, in this volume.
