T1ESFCSUACE
Stand Alone and Smart 16 T1 Network Facility Interface
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.
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 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 stand-
alone 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.

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.
