NT6D80 MSDL card

A D-Channel on the MSDL requires a connection from the appropriate
MSDL port connector to the DCH connector located on the ISDN PRI trunk
faceplate.

Other operations on the MSDL are connected to external devices such as
terminals and modems. To complete one of these connections, connect
the appropriate I/O connector on the MSDL to a connector on the I/O panel
at the back of the module where the MSDL is installed. If a terminal is
connected to the regular SDI port, use 8 bit, VT100 terminal emulation. If
the terminal is connected to the SDI/STA port with line mode editing, use 8
bit, VT220 terminal emulation.

To determine the type and number of cables required to connect to MSDL
cards, you must determine the type of operation you wish to run and select
the appropriate cable to connect the operation to the MSDL port. Different
types of cables, as described in

Table 163 "Cable types" (page 399)

,

connect the MSDL port to a device:

NTND26, used to connect the MSDL port to the ISDN PRI trunk
connector J5, for DCH

QCAD328, when cabling between two different columns, that is, I/O to
I/O (when MSDL is in one row and QPC720 is in another row)

NTND98AA (J5 of QPC720 to I/O panel)

NTND27, used to connect the MSDL port to the I/O panel at the rear of
the module, for other interface functions
