Channels in DAHDI devices (such as DAHDI PCI cards) are groups to logical units called «spans» (for example: a port in a digital card is a span).

span ⇒ <Number>,<Timing>,<Line BuildOut>,<Framing>,<Coding>[,Yellow]

Timing:

This determines how timing is handled by the card.

  • 0 - Порт является источником синхронизации
  • 1 - Получает синхронизацию с удаленной станции

ccs: Common Channel Signaling (CCS) over a digital PRI. It is the transmission of signaling information out of the information band

hdb3: high density bipolar of order 3 - один из способов линейного кодирования, применяется при передаче данных на расстояние по цифровому каналу связи

crc4: Cyclic redundancy check - алгоритм нахождения контрольной суммы, предназначенный для проверки целостности данных

termtype: setting is for TE or NT (the default is TE), TE - cpe signallingget and get timing from the remote party, NT - provide timing to the remote party
