The purpose of the Restart indicator information element is to identify the class of the facility (i.e. channel or interface) to be restarted.
The Restart indicator information element is coded as shown in Figure 4-31 and Table 4-22.
The maximum length of this information element is three octets.

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. |
