CAUTION
Check if the module is equipped with BTUs that protrude
between card slot connectors in the network shelf. Do not
attempt to install the Local Carrier Interface card in the card
slot immediately to the left of a BTU. If Network Hybrid Kit
NT5D40AA is used instead of BTUs, the Local Carrier Interface
card can be installed into any superloop network card slot with
the network hybrid
Table 9 "Modules supporting Local Carrier Interface cards" (page 59)
modules that provide network card slots, the system options where these
modules are used, and card slots where network cards can be installed.
Card slots that might be physically restricted by BTUs are identified by a
Note in Table 9 "Modules supporting Local Carrier Interface cards" (page
59). The right-hand superloop card slots can be used if the slot does not
have a BTU.

Note: Card slot 11 and 12 can be used with NT8D35BA and NT8D35EA vintage
Network Modules or Network Modules with NT8D3507 backplane, which are
equipped with network Hybrid Kit NT5D40AA instead of BTUs. In older vintage
NT8D35 Network Modules, NT9D11 Core/Network Modules, and NT6D39
CPU/Network Modules, a BTU upgrade kit can be used to replace the BTUs to
be able to use the card slots identified with the Note for the installation of the
Local Carrier Interface card.
The NT5D40AA Hybrids Kit includes four network hybrids required
to replace two BTUs in a single network shelf or module. The kit also
includes the extraction tool that must be used if a network hybrid has to
be removed.
