Channel Release Request 0x0037
SwitchKit Name
Type
EXS API and SwitchKit API message
Description
The conditions in which the Excel platform uses this message depends on the protocol you are using.
An SS7 channel reports this message to the host if both of the following conditions exist:
• The SS7 channel is connected to a channel that is released
• The release modes for the channels call for the SS7 channel to be released
This lets the host insert parameters for the outgoing ISUP REL using the Release Channel With Data message. If no data is to be inserted, the host may use the Release Channel message.
The Excel platform sends this message to the host upon a network-initiated ISDN Disconnect message if the ISUP mode configuration is set to allow release upon a disconnect. The host responds with either a Release Channel message or a Release Channel With Data message to send information to the ISDN with the release.
