D Channel De-assign 0x00C5

SwitchKit Name

DChannelDeAssign

Type

EXS API and SwitchKit API message

Description

D Channel De-assign 0x00C5

This message is used by the host to de-assign an ISDN PRI D channel. The D channel may then be re-assigned using the D Channel Assign message. D channel De-assign messages must be sent for each of the D channels (DSOs) making up the Super Rate D channel. The base D channel must be de-assigned before any of the others can be de-assigned.

Data channel. One of two fundamental components of an ISDN interface, it provides a path (16Kbps for BRI, 64Kbps for PRI) for carrying control signals and call data in a packet-switched mode.
See Integrated Services Digital Network.
A computer, attached to the Excel platform through an RS-232 or Ethernet link, from which you run the telecommunications application that controls the Excel platform.
Range of channels provided by T1 or E1 transmission service. A physical span is a group of channels taking up a single physical wire. A logical span is a group of channels taking up less than a single logical wire, or carried over more than one physical wire.
A group of data bits in a specific format, with a flag at each end to indicate the beginning and the end of the frame.
