slot, management interfaces, and a T1 interface, in the rear
panel. See Figure 2-3.
Figure 2-3. TSU 100 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 Appendix C, Wiring on page
C-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 bro-
ken, and the test equipment will terminate the incoming T1.
The
R-MON test jack
provides a bridged access jack for non-
intrusive monitoring of the incoming T1. When connected to
this jack, the test equipment should be configured for a bridged
termination.
Nx/DBU Serial Interface (TSU 100e only)
The Nx/DBU provides a serial V.35 port that operates from
56kbps to 1.536Mbps. This port provides 511 pattern genera-
tion and detection and remote loopback capability. (DBU in
TSU 100e only.)
