### Description

```asn1
sigChanMcdnChanMaintenanceHandling OBJECT-TYPE
SYNTAX INTEGER {
globalOnStartup(0),
serviceMessage(1),
restartMessage(2) }
ACCESS read-write
STATUS mandatory
DESCRIPTION
"This attribute specifies handling of channel maintenance events
such as locking and unlocking a channel or channel registration on
start-up. The decision here is whether to send individual channel
RESTART messages, SERVICE messages, or nothing. Note that
channel registration only occurs after the global interface restart at
startup.

The attribute controls start-up handling absolutely, and channel lock
and unlock conditionally. That is, setting this to enable SERVICE
messages ensures SERVICE messages at start-up and whenever a
channel goes into or out of service. However, if this is not set to
enable SERVICE messaging, a RESTART is always sent on
unlocking a channel.

globalOnStartup provides the minimum required function at start-
up, without any individual channel confirmation. Note that when
this is set, channel RESTART is still used for channel unlock.
globalOnStartup applies to SigChan start-up only.

serviceMessage enables sending and receiving SERVICE messages.
If enabled, SERVICE messages are always used for channel
maintenance on channel lock, channel unlock and start-up.

restartMessage provides individual channel RESTARTs when a
SigChan starts up. If enabled, the RESTART is used at start-up and
channel unlock. However, if both SERVICE and RESTART
messages are disabled, the RESTART will still be used when a
channel unlocks."
