E1 interface options

Line interface options of the From Network and  the From User connections :

  • Transmit options
    • Short-Haul 120 Ohms
    • Short-Haul 75 Ohms
    * For Clarinet-Book SCSI type, this option can be used to link a transmit equalizer with any selection except the first one. 
  • Receive equalizers
    • Standard cable loss
    • 20 dB flat loss
    * Not supported by Clarinet-Book SCSI type.

Input impedance. Impedance mode of the Clarinet interface imputs:

  • --. default 120 Ohms
  • High impedance
  • 75 Ohms
  • 100 Ohms
  • 120 Ohms
* For Clarinet-Book SCSI type, this option can be used to set high impedance inputs with any selection except the first one (fixed hardware version 120 or 75 Ohms).

Abcd signalling on time slot 16. To select G704 CAS on TS 16.

Crc4 multi-frame. The bit 1 of TS0 is used for CRC4.
