TSU 600 Interfaces
The TSU 600 is equipped with six option slots, management interfaces,
and a T1 interface, in the rear panel. See Figure 2-2.
Figure 2-2. TSU 600 Interfaces
Network Interface
The network interface (NI) port provides the connection to the T1. This
port complies with the applicable ANSI and AT&T standards. For more
information, see Wiring on page B-1.
Network Test Interface
The IN and OUT test jacks for the network interface provide intrusive
test capability for the incoming T1. By connecting to these jacks with test
equipment, the T1 connection will be broken, and the test equipment
will terminate the incoming T1. The
MON test jack provides a bridged
access jack for non-intrusive monitoring of the incoming T1. When con-
nected to this jack, the test equipment should be configured for a
bridged termination.
Control Port Input
The control port input provides an EIA-232 input from a PC or a modem
for control of the TSU 600. You can also use it as a chain input from an-
other TSU 600 or TSU 100. For more information, see Wiring on page C-
1.
Chain Port Output
The chain port output provides an EIA-232 output to chain control to
other TSUs. For more information, see Wiring on page C-1.
