Installation and configuration
systems, the IP Line card can be provisioned in the main or expansion
cabinets. In an Option 11 main cabinet the IP Line card cannot be configured
as an XDLC card in slots 9 or 10 if the Meridian Mail Card Option is present
in card slot 10.
In order to accommodate the maximum number of IP Line cards per module,
each card should preferably be installed such that the left slot is an
even-numbered slot and the IP Line card is configured as an XDLC card in
the even-numbered slot.
The IP Line card may be configured as an XDLC card in an odd-numbered
slot, if the maximum IP Line card density per module is not required.
Note: In NT8D37AA IPE shelves only 16 tip and ring pairs are
supported for most card slots. Since the IP Line card requires 24 tip and
ring pairs in the left-hand card slot, the IP Line card can only be
configured as an XDLC card in slots 0, 4, 8, and 12 in the NT8D37AA
IPE shelf. The NT8D81AA IPE Expansion Kit is available to modify the
older shelves in order to bring out 24 tip and ring pairs per card slot.
Note: It is not necessary to install all IP Line cards that belong to the
same node in the same IPE shelf. For multi-card ITG nodes, it is
recommended that the cards be provisioned in separate IPE shelves. This
is to avoid total loss of IP telephony capability in case of the failure of a
single IPE shelf.
Do not install an IP Line card into an IPE card slot if that card slot has
been configured for a central office trunk card. Before you insert the
card into the card slot, disconnect the cable connecting this card slot to
the MDF. Central office trunk cards may receive ringing voltage or
other foreign voltage, which, when applied to the IP Line card, may
damage the card.
Identify the IPE card slots selected for the IP Line card(s).
