If the optical interfaces that support conference calls form a loop, howler tone is generated. Hence,
"releasing loop" is required, that is, only one optical port can be set for the conference calls on a certain
node.
The conference call numbers for all the NEs must be the same, and must have the same length as the
corresponding orderwire phone numbers. If the orderwire phone number has four digits, it is recommended
that you set the conference call number to 9999.
