Contents
This section contains information on the following topics:
"Install NTBK51 DDCH on NT5D97 dual-port DTI2/PRI2 card" (page 91)
"Remove NTBK51 DDCH from NT5D12 dual-port DTI/PRI" (page 94)
Introduction
This chapter provides installation and removal procedures for the NTBK51
Downloadable D-channel Daughterboard, the NT5D97 dual-port DTI2/PRI2
card, and the NT5D12 dual-port 1.5 Mb DTI/PRI card on all Large Systems.
Note: The only version of the NTBK51 DDCH that can be used on an
NT5D97, or NT5D12 installed on a Large System, is the NTBK51AA.
Vintage NTBK51BA cannot be used, due to a different pin configuration
(the NTBK51BA is used on Small Systems.)
Before beginning an installation:
•
Consult the Spares Planning (NN3001-253) document and follow the
instructions.
•
Bring spares of all cables and boards.
•
Remember that test procedures require a 24-hour minimum bit error-rate
testing before being used.
•
Remember that either the DDCH, the MSDL, or NT5D97, or NT5D12
card can be installed first. However, NT5D97 PRI2 loops, and NT5D12
PRI loops, must be configured in software before defining DCH links.
