NOTE :(Refer figures 4.2d , 4.2e)
e) Reference digital trunks may be terminated on NSE as follows
Ref. DTK1 : NSE J17 tab 1, Ref. DTK2 : NSE J17 tab 3 , Ref. DTK3 : NSE
J17 tab 3
f) For terminating reference digital trunks do the following
•
Remove existing jumpers from Rx to Rx for ref. digital trunks between tag
blocks A & B
•
Terminate Rx pairs of ref.digital trunk 1 from tab blocks on 7x2 connector
for NSE J17 tab1 as shown in fig.4.2e
•
Similarly, terminate Rx pairs of ref.digital trunks 2 & 3 on two different 7x2
connectors for tab 2 & tab 3 of NSE connector J17.
• Keep 7 x 2 connectors always plugged in NSE J17 connector to avoid break
in Rx pairs of digital trunks going to switch room.
