ITG Trunk 2.0 ISDN Signaling Link (ISL) Description, Installation and Operation
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 1.0 to 2.0 in field upgrades. It breaks out the signals from the
I/O connector on large systems and Option 11 to the ethernet management
port (E-Lan connection) , ethernet voice port (T-Lan connection), one
maintenance RS232 port brought out on a 9-way D-type connection plus the
Dchannel 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 System) 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
Meridian 1/ Option 11 systems via the mounting screw provided on the top of
the 25 pair Amphenol connector.
The NTCW84LA/MA cable provides a shielded RJ45 to RJ45 coupler at the
end of its E-LAN and T-Lan interfaces. This provides the connection point to
the customers E-LAN equipment. Shielded Cat. 5 cable must be used for
connection from this point to the customers Hub or Router. See Figure 64 and
Table 63.
Note: For all LAN cables originating from the ITG card, standard cable
ties should be adopted to bundle these cables together as they route out
of the system.
