Overview
This chapter provides the information required to install the 2.0 Mb DTI card
in Meridian 1 Option 11C systems. It includes information for:
• hardware installation
• software programming
With the introduction of Release 25.3x, the 2.0 Mb DTI card is now supported
in Option 11C IP expansion cabinets. This increased capability is possible
with the introduction of IP daughterboards in expansion cabinets and
100BaseTor F connectivity with the Main cabinet.

Hardware Requirements
Hardware requirements for 2.0 Mb DTI are as follows:
• 2.0 Mb DTI Circuit card - NTAK10
(a Clock Controller is incorporated into the circuit card)
• CEPT Cable – NTBK05DA (120 ¾ twisted pair – 6.15 m length)
or
CEPT Cable – NTBK05CA (75 ¾ coaxial – 6.15 m length)

Option 11C 2.0 Mb DTI/PRI
NTAK10 2.0 Mb DTI card
The 2.0 Mb Digital Trunk Interface card provides the physical interface for
the digital E-1 carrier on the Option 11C system. The card includes an
on-board clock controller and is installed in slots 1 through 9 in the main
cabinet. On IP Expansion cabinets, it may be placed in slots 11-19, 21-29,
31-39, 41-49 of the first, second, third, and fourth expansion cabinets,
respectively.
The NTAK10 2.0 Mb DTI card is also used for ISL shared mode applications.
For information on the NTAK10 faceplate LEDs, refer to DTI Maintenance
in this guide.
Install DTI hardware
The NTAK10 circuit card can be installed in any available card slot 1-9 in the
main cabinet. On IP Expansion cabinets, it may be placed in slots 11-19,
21-29, 31-39, 41-49 of the first, second, third, and fourth expansion cabinets,
respectively
Inspect the NTAK10 circuit card
Inspect the circuit card before installing it in the main cabinet:
• Locate the NTAK10 2.0 Mb circuit card and carefully remove it from its
packaging.
• Inspect the circuit card for any visible damage which may have occurred
during shipping.
Set the switches
The NTAK10 incorporates four surface mounted dip switches. The following
tables provided information on the various settings and related functions of
these switches.
Note: The ON position for all the switches is towards the bottom of the
card. This is indicated by a white dot printed on the board adjacent to the
bottom left corner of each individual switch.
Set the switches found on the circuit card as per the requirements of your
specific installation.

Switch S1—Clock Controller Configuration
This switch enables/disables the on-board Clock Controller.
Switch S2—Carrier Impedance Configuration
This switch sets the carrier impedance to either 120¾ or 75¾. Twisted pair
cable is usually associated with 120¾. Coaxial cable is usually associated
with the 75¾ setting.
Switch S3—Mode of Operation
This switch selects the mode in which the NTAK10 operates. The NTAK10
supports firmware that allows it to operate in the standard CEPT format
mode, or the modified CEPT format used in France.

Option 11C 2.0 Mb DTI/PRI
Switch S4—Carrier Shield Grounding
This switch allows for the selective shield grounding of the Tx and/or Rx
pairs of the carrier cable. Closing the switch (down position) applies Frame
Ground (FGND) to the coaxial carrier cable shield, creating a 75¾
unbalanced configuration. The Tx and Rx pairs are referenced with respect to
the 2.0 Mb DTI card (i.e. Rx is carrier received from the far end device).
Note: The usual method is to ground the outer conductor of the receive
coax signal.
Insert the NTAK10
Slide the circuit card into any unused slot 1 through 9 in the main cabinet, or
in slots 11-19, 21-29, 31-39, 41-49 of the first, second, third, and fourth IP
xpansion cabinets, respectively. Secure the circuit card in the cabinet by
locking the lock latch assemblies.
Connect the cables
• In the cabling area, located directly below the card cage, remove the
retaining bar used to secure the MDF cables. Connect the
NTBK05DA/CA interface cable to the 50-pin Amphenol connector
below the card slot holding the NTAK10 2.0 Mb DTI circuit card.
Re-install the retaining bar to secure the cable(s) in place.
• Terminate the NTBK05DA/CA carrier cable as required.
