Description

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-mounting or desktop use, while the T1 ESF CSU Smart 16 Card occupies a single slot in the ADTRAN Smart 16 shelf. A front panel LCD and four user keys on the front of the ACE provide easy configuration and unit monitoring from the front panel. The Smart 16 ESF CSU card can be controlled from the shelf controller through a VT 100 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 inter-face 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 ANSI PRMS information in 15 minute intervals for 24 hours, which is fully accessible from the front panel, over the FDL, or via a dial-up modem connection.

Remote configuration is made simple by using the FDL channel of a T1 ESF formatted circuit with the front panel or the Smart 16 controller interface. Using the remote configu-ration capability of the T1 ESF CSU enables central site control and setup for ADTRAN T1 CSUs or TSU devices. Compatibility with the popular T-Watch PRO software package enables the T1 ESF CSU to integrate easily into ADTRAN TSU environments.
