This appendix describes the NTMF94DA, NTAG81CA and NTAG81BA
cables.
The NTMF94DA provides the E-LAN, T-LAN ports that provide the
interface from the IP Line card to the customer's network equipment, and one
DB9 serial port that provides serial connection between the card and the
customer PC or TTY (see Figure 26). Table 23 describes the NTMF94DA
cable pins.
It is very important to use the mounting screw provided to secure the top of
the NTMF94DA cable 25-pair Amphenol connector to the Meridian 1. The
screw ties the LAN cable shield to the Meridian 1 frame ground for EMC
compliance.
The NTMF94DA cable provides a factory installed, shielded, RJ45 to RJ45
coupler at the end of both the E-LAN and T-LAN ports. An unshielded
coupler is provided to prevent ground loops (if required). Turn to page 250
for a test that helps you decide if you have to use the unshielded coupler. Both
ends of the RJ45 ports of the cables are labeled as to which is the T-LAN and
which is the E-LAN. The ports provide the connection point to the customer's
E-LAN and T-LAN equipment. You must use shielded Category 5 cable to
connect to the customer's equipment.
To improve EMC performance, use standard cable ties to bundle all LAN
cables as they route out of the system.
Note: To avoid damage to Category 5 cable, do not overtighten cable
ties.
