check the end-to-end data transmission on the data port. If transmission
does not work properly, choose

EQP Handshaking
The DIU 2130 and DIU 1130 supports five handshaking signals on each
data port. The V.35 names appear in the DIU menu screen, although
RS449 and RS530 interfaces are also available. Set each signal to
N or Y .
The DIU 2130 and data port handshaking signals are listed below.

NOTE 1. (CTS) Set this option to NO (default) if you want CTS from the DIU to follow conditioned RTS from the data
equipment. If NO , CTS turns off automatically if the associated NCC, CCC, or TAC goes into an LOF state or receives a
Yellow (i.e., RAI) alarm regardless of RTS. Or, set this option to YES to permanently turn on DSR.
NOTE 2. (DSR) Set this option to NO (default) if you want DSR from the DIU to follow conditioned DTR from the data
equipment. If NO , DSR turns off automatically if the associated NCC, CCC, or TAC goes into an LOF state or receives
a Yellow alarm regardless of DTR. Or, set this option to YES to permanently turn DSR on.
NOTE 3. (RLSD) Set this option to NO (default) if you want RLSD on except when the associated NCC, CCC, or TAC
goes into an LOF state. Or, set the RLSD t YES to permanently turn it on.
