This attribute specifies the number of Logical Connections (LC)
preestablished between each DcmeLink associated with this Dcme
and its remote peer, that are established beyond those that are
required to carry established connections. Those are the standby
LCs to be used for the subsequent user speech or audio 3.1 kHz
calls. This attribute should be set to the number of speech and audio
3.1 kHz calls expected in a typical burst of calls received from the
ISC on one DcmeLink.
