+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:
+<code>
+: 0 db (CSU) / 0-133 feet (DSX-1)
+: 133-266 feet (DSX-1)
+: 266-399 feet (DSX-1)
+: 399-533 feet (DSX-1)
+: 533-655 feet (DSX-1)
+: -7.5db (CSU)
+: -15db (CSU)
+: -22.5db (CSU)
+</code>
+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
