NT5K93 Central office trunk circuit card
Functional description
The NT5K18BA Central Office trunk card provides the interface between the
Option 11 system and up to eight analog Central Office (CO) trunks. It can
be installed in slots 1-9 in the main cabinet and in any slot in the expansion
cabinet.
Trunk types supported
The Central office trunk card has eight identical units. The trunk type of each
unit is configured independently in the trunk data block (LD 14) as one of the
following:
•Central office - ground start
•Central office - loop start
The NT5K18BA central office card also supports Direct Inward System
Access (DISA).
Common features
The NT5K18BA Central office trunk card:
•allows trunk type to be configured on a per unit basis
•provides disabling of individual units or the entire card through
software
•indicates self-test status during an automatic or manual self-test
•converts transmission signals from analog-to-digital and from
digital-to-analog

New Zealand standards.
Physical description
Measurements
Each NT5K18BA Central office trunk card measures as follows:
Switch settings
There are no option settings on the NT5K18BA Central office trunk card. All
settings are configured in software.
Connections
The NT5K18BA Central office trunk card has eight units. Each trunk unit on
the card connects to the backplane through an 80-pin connector. The
backplaneiscabledtotheinput/output(I/O)panel,andtheI/Opaneliscabled
to the cross-connect terminal. At the cross-connect terminal, each unit
connects to external apparatus by tip and ring leads.
Hardware installation
Table 1 provides cross connect information for the NT5K18BA Central
Office trunk card.

Self-test
When the card is installed, the red Light Emitting Diode (LED) on the
faceplate flashes as the self-test runs. If the self-test completes successfully,
the card is automatically enabled (if it has been configured in software) and
the LED goes out. If the self-test fails, the LED will remain lit. The LED will
also remain lit if one or more units on the card become disabled while the card
is operating.
Trunk configuration
Route Data Block
Each trunk unit on the NT5K18BA central office trunk card is attached to a
route with an associated route data block. Trunk timers are configured on a
route basis.
Note: All prompts are defaulted except for those noted in Table 2.
Default values are shown in brackets.
