442 Appendix B Cable description and NT8D81BA cable replacement
NTCW84LA and NTCW84MA upgrade cables
The following cables are required for the upgraded 8-Port ITG ISL Trunk
DCHIP card:
• NTCW84LA for upgraded NTCW80CA cards
• NTCW84MA for upgraded NTCW80AA cards
The NTCW84LA and NTCW84MA shielded cables are required on DCHIP
cards for ITG Trunk 1.0 to ITG Trunk 2.0 in field upgrades. It breaks out the
signals from the I/O connector on Large systems and Option 11 to the ELAN
network interface, TLAN network interface, one maintenance RS-232 port
brought out on a 9-way D-type connection, and the D-channel port brought
out on a 15-way D-type connection. The NT8D81AA cable is used to bring
all 24 tip and ring pairs (on Large systems) from the backplane to the I/O
panel and mates with the NTCW84LA cable.
It is very important that the NTCW84LA/MA cable be secured to the system
with the mounting screw provided on the top of the 25-pair Amphenol
connector.
The NTCW84LA/MA cable provides a shielded RJ-45 to RJ-45 coupler
at the end of its ELAN and TLAN network interfaces. This provides the
connection point to the customer’s ELAN subnet equipment. Shielded CAT5
Ethernet cable must be used for connection from this point to the customer’s
hub or router. See
Figure 154 "NTMF94LA upgrade cable" (page 443) and
Table 77 "NTMF94LA cable connections" (page 443) .
For all LAN cables originating from the IP trunk card, standard cable ties
should be adopted to bundle these cables together as they route out of
the system
