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 connection 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 ter-
mination.
