Type

EXS API and SwitchKit API message

Description

D Channel Facility List Configure 0x00C6

This message is used by the host to add or delete spans from the facility list of D channels in NFAS mode. A D channel can control up to 20 spans of NI2 channels and 10 spans for all other channel types. The span where the D channel is assigned is automatically added to the facility list as Facility 0. You do not need to add it to the facility list using this message.

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 Non Facility Associated Signaling.
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.
See Address Information Block.
