Provisioning Orderwire
To provide the maintenance personnel with a dedicated express orderwire channel, you can configure orderwire for NEs.
Configuring Express Orderwire
In the case of two NEs without a fiber connection, you can configure the express orderwire to provide the maintenance personnel with an express orderwire channel between the NEs.
Configuring Conference Calls
To provide the maintenance personnel with a dedicated express channel that allows concurrent voice communication among multiple NEs, configure the conference calls for NEs.
Dividing Orderwire Subnets
When there are too many NEs, the concurrent conference calls affect the quality of the conversation. You can assign the subnet number to optical ports, where the conference calls are configured, to allocate the NEs to different orderwire subnets. You can make the conference calls between NEs that are associated with the same orderwire subnet.
