ADTRAN T1 ESF CSU ACE (4th Gen) - CSU

The ADTRAN T1 ESF CSU is a full-featured T1 Channel Service Unit used to connect T1 data terminal equipment (DTE) such as a PBX, switch or channel bank to T1 facilities. Capable of interfacing to both B8ZS or AMI circuits, the T1 ESF CSU can convert signal formats or line code to integrate older equipment. The ESF CSU is designed to provide alarms, loopbacks, signal regeneration, line build-out, and surge protection, while maintaining 1's density for the DTE and T1 network.

The T1 ESF CSU ACE is suitable for wall- or rackmounting or desktop use, while the T1 ESF CSU Smart 16 Card occupies a single slot in the rackmount ADTRAN Smart 16 shelf. The standalone models provide a front panel LCD, four user keys on the front of the ACE, and provides easy configuration and unit monitoring from the front panel. The ESF CSU provides an EIA- 232 port (DB-9) for provisioning through a VT100 interface. The Smart 16 ESF CSU card can be controlled from the shelf controller through a VT100 interface or the optional Datamate. For SNMP management, the Smart 16 ESF CSU card is supported by the Smart 16e controller and the ADVISION software package.

The T1 ESF CSU provides a T1 network interface and a DSX-1 DTE connection through modular RJ48C jacks. For testing purposes, the T1 ESF CSU is capable of initiating several built-in local and remote loopback tests and conducting stress testing of the network with built-in test patterns. For more extensive network testing, the unit uses bantam jack access for external test equipment. To aid with circuit monitoring, the T1 ESF CSU gathers AT&T maintenance information in 15 minute intervals for 24 hours, which is fully accessible over the FDL or via the Smart 16 controller.

Remote configuration is made simple by using the FDL channel for the standalone ACE or the Smart 16 controller interface for the rackmount version. Using the remote configuration capability of the T1 ESF CSU enables central site control and setup for ADTRAN T1 CSUs or TSU devices.

The standalone ACE includes an autoranging 12-48V internal DC power supply and wallmount AC power supply. The L2 version adds a terminal block for easier connection to an external DC supply.

For additional T1 applications, ADTRAN provides several T1 DSU/CSUs and T1 Multiplexers for combining traditional DSX-1 functionality with additional DTE ports. The TSU 100e, TSU 120e and TSU 600e are modular T1 DSU/CSUs with embedded SNMP and are capable of supporting a single DSX-1 interface and up to 22 DTE interfaces for data or video applications.
