  701282-3 BET Module  
  BET Module, 16 E1/T1 Lines + a Single E3/T3 Line 701182-3
The Technisys LINE BET Module is designed for use with the 701180-1D 1U Modular Laptop Size Chassis. It is capable of providing framed or unframed, high speed, serial binary output ranging from T1 to T3 rates. Frame/unframed operatioin is selected by an on-board jumper. Line outputs can be encoded with applicable zero suppression techniques. All low rate (E1/T1) electrical I/O is through 68 pin SCSI connectors while E3/T3 is handled via industry standard BNC connectors.

Signal levels include single ended AMI for E3/T3 rates and differential AMI for E1/T1rates.

All controls and indicators are located on the front panel and I/O is on the rear panel. All switches, except the RUN/STP/RST, are momentary rocker switches. The RUN/STP/RST is an ON/OFF/Momentary switch.
