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.
