General 1-12010 CSU

General

1.0 Introduction

The TxPORT 2010 ESF CSU provides an economical solu-

tion for interfacing a metallic T1 facility to customer pro-

vided T1 equipment. The 2010 supports ANSI T1.403 or

AT&T 54016 ESF CSU requirements.

The 2010 may be ordered as a stand-alone unit or as a mod-

ular card for mounting in a chassis. When the 2010 is paired

with a TxPORT 2000 CSU at the far end, the 2010 can be

managed over the TxPORT EM8000 element manager net-

work.

For applications requiring the use of alarm contacts, the unit

may be ordered with an ACO and alarm card. The 2010 has

primary and secondary surge protection on both the network

and DTE side (meeting UL 1459 requirements).

The unit provides ALBO circuitry on the network path and

DSX circuitry on the DTE receive paths. The network

ALBO supports a receive range of +1 dB to -30 dB. The

DTE supports DSX1 signal ranges up to 655 feet.

The unit also provides LBO circuitry on both network and

DTE. The network transmit LBO is user selectable (0, -7.5,

-15, and -22.5 dB). The DTE transmit LBO is user select-

able in four incremental ranges from 0 to 655 feet.
