Evaluation Board for Octal E1 Applications — LXD381
Developer Manual 5
1.0 General Description
The LXD381 evaluation board is a versatile tool for engineers designing E1 short haul applications
using the LXT381.
The evaluation board operates in Hardware mode only. All device and channel controls are set
using jumper blocks and DIP switches.
The board provides banana jacks for both power and line interface connections. Connectors are
provided for each framer or back-end ASIC interface. An E1 pattern generator/analyzer may be
used to provide external signals for evaluation.
