Install and cable IP Trunk 3.01 (and later) cards 191
Each ITG-Pentium 24-port trunk card requires two slots in a IPE shelf. Only
the left slot of the card requires connection to the system IPE backplane
and I/O panel. Each Media Card 32-port trunk card requires only one slot in
the system IPE shelf.
At least one DCHIP card must be installed in an IP Trunk 3.01 (and later)
node. The D-Channel (DCH) PC Card and the associated NTCW84EA
DCHIP PC Card Pigtail cable must be installed on to the DCHIP card.
Install a maximum of eight IP trunk cards in an IPE shelf. The ITG-Pentium
24-port trunk card can occupy any two adjacent slots in an IPE shelf, with
the left slot of the card plugging into slots 0 to 6 and 8 to 15. The left slot
of an IP trunk card cannot be plugged in slot 7, because the XPEC card is
situated in-between slots 7 and 8.
To allow a module to hold the maximum number of IP trunk cards, install
each ITG-Pentium 24-port trunk card with the left slot of the card inserted
in an even-numbered slot.
If the maximum card density for each module is not required, the left slot of
the IP trunk card can be inserted in an odd-numbered slot.
The required software version on the ITG-P card is version 5.7.
The ITG-Pentium 24-port trunk card requires 24-pair tip and ring I/O cabling.
NT8D37AA IPE modules have 24-pair tip and ring I/O cabling for card slots
0, 4, 8, and 12 only. Insert the left slot of the IP trunk card in NT8D37AA slots
0, 4, 8 or 12 only. NT8D37BA or later IPE modules have no such restriction.
When multiple IP trunk cards are installed, distribute them between available
IPE shelves. This prevents total loss of IP trunking, in the case of localized
shelf failure.
CAUTION
CAUTION WITH ESDS DEVICES
Wear an electrostatic discharge strap when handling IP trunk
cards. As an additional safety measure, handle all cards only
by the edges and, when possible, with the loosened packaging
material still around the component.
CAUTION
Equipment Damage
Never install an IP trunk card in an IPE shelf that has been wired
for a Central Office Trunk (COT) card. Before inserting the card
into the slot, disconnect the cable connecting this card to the Main
Distribution Frame (MDF). COT cards can receive ringing voltage,
which, when applied to an IP trunk card, can damage the card.
