Install NTBK51 DDCH on NT5D97 dual-port DTI2/PRI2 card

553-3001-201 Standard 2.00
NTBK51 DDCH installation and removal
• 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.
Installation procedures for the NTBK51 DDCH are the same for all Large
Systems. Use Procedure 5 below.
The DDCH can be mounted on any NT5D97 DDP2 card. Set the address for
the DDCH (see the switch settings section to set the address). If a DDCH is
present on a DDP2 card then an external D-channel should not be connected
to J6. If a DDCH is present the LED "DDCH" lights up.
CAUTION
The static discharge bracelet located inside the
cabinet must be worn before handling circuit cards.
Failure to wear the bracelet can result in damage to
the circuit cards.
Procedure 5
Install the NTBK51 on the NT5D97 dual-port DTI2/PRI2 card
1 Unpack and inspect the DDCH daughterboard.
The DDCH comes with four stand-offs so that it can be mounted onto the
NT5D97. These are easily pushed into four corresponding mounting
holes on the DDP2.
2 Mount the DDCH so that it mates with P1 and P2 on the NT5D97
motherboard.
Note: P 1 and P 2 contain (40+30) sockets as the NTBK51AA respective
pins (40+30), which enables the technician to "mate" them. This is
applicable for the NT5D97AA/AB. The NT5D97AD has 44+34 sockets. In
order to place the NTBK51AA (40+30 pins), place the NTBK51AA inside
P1 and P2. Start from their lower edge. (The remaining "free" sockets
(4+4) in P1 and P2 are in their upper edge.)
