CHAPTER 9: Data-Channel Configuration

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
.
Unless you have the optional NMS installed, you
must leave one port configured for async (to access
the Command Facility).
P ROTOCOL M ENU
Configure the port for sync.
The following protocol menu will appear:
Select a channel protocol from the menu.
Table 9-1
explains each option. Pressing M will abort
the process.
After you have selected the appropriate protocol,
the CONFIGURE LOCAL NODES menu will
reappear. You may continue to configure data ports
as either sync or async.
Important
Once you have completed your port
configurations, you must do a node
reset using the current configuration
option.
Until the Multiserver has been node-reset, you will
not be able to set any sync channel parameters.
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.)

To continue with the sync configuration process,
select option 3, Sync Channel, from the Configure
Local Nodes Menu.
The screen will display the following prompt:
Enter the node ID/channel number followed by a
carriage return to accept the entry.
If you see CONFIGURATION INHIBITED and WRONG
CHANNEL TYPE
messages, the port you have chosen
is not configured as a sync channel. It is likely that a
node reset (to current configuration) was not
