NOTES
- 1 The channel identification information element must be included and indicates which channels are to be restarted.
- 2 If non-associated signalling is used, the channel identification information element must be included to indicate the interface to be restarted if it is other than the one on which the D-channel is present.
- 3 May be used when there are two or more interfaces controlled by the D-channel. The channel identification information element must not be included with this coding.
