7.84 Enabling LCAS

Description
The Enabling LCAS parameter can increase or decrease the SDH network capacity without
affecting the service. The capacity is automatically decreased if a member fails, and is
automatically increased if the member recovers.
Impact on the System
As a bidirectional protocol, the LCAS can work normally only when some bandwidth is available
in the bidirectional physical paths. If the bandwidth is available in the unidirectional physical
paths only, the LCAS may fail to correctly adjust the bandwidth.
