Cross Disconnect Span 0x001D

SwitchKit Name

CrossDisconnectSpan

Type

EXS API and SwitchKit API message

Description

Cross Disconnect Span 0x001D

This message disconnects all data paths of two spans that were previously connected by means of the Cross Connect Span message (XL_CrossConnectSpan).

NOTE: When cross-connecting channels across nodes in a CSP system, a separate message must be sent to each channel in the connection.

For example, you would send one message to Node 1: Cross Disconnect Span (CrossDisconnectSpan) 0,1. You would send another message to Node 2: Cross Disconnect Span (CrossDisconnectSpan) 1,0.

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 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.
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.
