 +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
 +
 +Line BuildOut:
 +
 +The line build-out (or LBO) is an integer, from the following table:
 +
 +0: 0 db (CSU) / 0-133 feet (DSX-1)
 +1: 133-266 feet (DSX-1)
 +2: 266-399 feet (DSX-1)
 +3: 399-533 feet (DSX-1)
 +4: 533-655 feet (DSX-1)
 +5: -7.5db (CSU)
 +6: -15db (CSU)
 +7: -22.5db (CSU)
 +
 +Framing:
 +
 +ccs - Common Channel Signaling (CCS) over a digital PRI. It is the transmission of signaling information out of the information band. ISDN Q.931 signaling is referred to as a CCS
 +
 +Coding:
 +
 +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
