Switch SW4—Carrier Shield Grounding
This switch allows for the selective 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. This applies only to the NTBK05CA cable.
Switch Down (On)
SW 4-1 Rx—FGND
SW 4-2 Tx—FGND
Note: The usual method is to ground the outer conductor of the receive
coax signal.
Slide the circuit card into any unused card slot 1 through 9 in the main cabinet.
Secure the circuit card in the cabinet by locking the lock latch assemblies. The
card number associated with a 2 Mb PRI card is based on the slot in which the
card is installed.
Follow the instructions below to connect cables to the NTAK79 PRI card.
— 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 slot in which the NTAK79 is installed. Re-install the retaining
bar to secure the cable(s) in place.
— Terminate the NTBK05DA/CA carrier cable as required.
