Black Box 5000 manual Synchronous Channels, Configure the port for sync

9.2 Synchronous Channels

Sync is supported only when directly attached to a Multiserver. Feeder muxes can only support async or voice channels.

Sync channels are not switchable and must be force connected. Refer to Section 10.4, Synchronous Connections.

If you change sync protocols, be sure to configure both ends of the channel with the same protocol. Do a node reset on both the local and remote Multiserver units. (When changing protocol, the channel cannot be connected.)
