Test Interface

The NETWORK IN and OUT Bantam test jacks provide intrusive test capability for the incoming T1. By connecting test equipment to these jacks, the T1 con- nection breaks and the test equipment terminates the incoming T1. The MON IN and OUT Bantam test jacks provide a bridged access jack for nonintrusive monitoring of the incoming T1. When connected to this jack, configure the test equipment for bridged termination.
