Product Description

The ADTRAN T1 CSU ACE is a compact, full-featured T1 channel service unit used to connect T1 data terminal equipment (DTE) and T1 facilities.

The unit is designed to provide alarms, loopbacks, signal regeneration, line build out, and surge protection, as well as maintain 1s density for the DTE and T1 network.

The compact T1 CSU ACE is suitable for wallmounting or desktop use. Four LEDs on the front of the unit (POWER, LOOPBACK, EQUIPMENT LOS and NETWORK LOS) display the status of the unit.

Above the LEDs, five small switches provide settings for customer premises equipment and network line build-out (LBO) distances. A small switch located on the unit's faceplate enables manual loopback operation. The three switches allotted for the equipment LBO offer five combination settings for PBX termination at distances up to 655 feet. The two network LBO switches provide four combination settings from 0 to 22.5 dBs in 7.5 increments. The compact T1 CSU ACE provides three bantam jacks which are available for testing purposes. Two connections provide interruptive transmit and receive access toward the T1 network or the DTE device.

The third is a non-interruptive connection for monitoring data flowing in either direction. Two RJ-48C modular jacks provide the network and DTE connections. The -48 VDC power pack is included with the unit and plugs into a wallmounted socket. The T1 CSU ACE also supports a customer-supplied -48 VDC power source.
