8 Other interconnection requirements
8.1 Equipment lighting
If NE includes integrated lighting system, the system shall meet the lighting and illumination
requirements in ATT-TP-76400.
8.2 Test (Streaker) Cards
Network Transport Elements shall have test cards (e.g., streaker) to enable verification of the
network element hardware and the continuity of cabling, through the backplane, to the point of
termination such as DSX panels or frames.
The test card or cards shall not:
•
require the shelf to be powered for such testing.
•
interrupt existing service on any other slot.
The test card or cards shall:
•
Provide metallic access to each backplane terminating conductor via an appropriate
connector Bantam for DS1, including timing inputs, 440 for DS-3, STS-1 and E-3 Facilitate
electrical signal insertion and transmission toward the drop; especially for DS1 or DS3 signals.
•
Facilitate optical signal insertion and transmission for continuity checking of optical
jumpers that would, when such active Plug-In were installed, interconnect rear terminated Plug-
Ins utilizing shelf backplane(s) optical connectors/barrels using SC or LC connectors.
Note: Test Set connections on face of Plug-In shall conform to AT&T standard connectors.
8.3 MOBILITY BAR CODE LABEL STANDARDS
Introduction
Applying bar codes, as simple of a task as it may seem on the surface, can actually be
somewhat complex due to variations in equipment. These differences prevent a strict set of
rules from being applied across the board.
Below is a base set of ‘common sense’ guidelines to be followed by personnel responsible for
applying bar codes on mobility core equipment. Adhering to these guidelines improves the
consistency of where bar codes are applied and assists personnel performing the inventory
scan of the installed equipment.
8.3.1 Determining Bar Code Requirement
There are a few methods of determining that the unit requires a tag, meaning the equipment is
serialized (bar coded and tracked).
1.) The PO in CATS indicates which items are serialized and which items are not.
2.) A parts query in CATS will give you serial tracking information.
