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 r ing 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 445) and

Table 77 "NTMF94LA cable connections" (page 445).

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
