Line State Allows the line administrative state (in service and out of service) to be
persistent.
Admin State Control This control object is used to change the service state of the line from is to coos
or from coos to is. The resulting service state of the line is represented by
vismDsx1State. inService: transition vismDsx1State to is. In the course, the
MGs MGCs may get notified of this transition, e.g. in the case of MGCP
through emission of RSIPs to registered call agents according to policy.
forcefulOutOfService: Take the line out of service forcefully. This releases
any resources at the line. In the course, the MGCs may get notified of this
transition, e.g in the case of MGCP through emission of RSIPs to registered
call agents according to policy. gracefulOutOfService: Take the line out of
service gracefully. If there are no resources existing, vismDsx1State
transitions to coos immediately. If resources exist, vismDsx1State transitions
to poos thus initiating a graceful shutdown. In the course, the MGs MGCs may
get notified of this transition, e.g. in the case of MGCP through emission of
RSIPs to registered call agents according to policy.
Bearer Busy Code Used when vismTrunkConditionEnable is enabled on a line. It is a
configurable busy pattern sent out on the “Bearer” on the channels, which are
receiving remote ATM channel ID (CID) alarms. If this object is not set, it
assumes a default value of 255 for E1 and 127 for T1.
