Configuring Synchronous Services

Using Site Manager
See the Sync Priority parameter on page A-86 for information.
Setting the Hold Down Time
On a synchronous interface configured for dial services, you can specify a time
period (0 to 9999 seconds) for the router to wait before bringing down a backup
line. This delay allows time for the primary line to fully recover before
deactivating the backup line.
For a dial-on-demand interface, the Hold Down Time parameter is set to 3 seconds
by default.
For other interfaces, the Hold Down Time parameter is set to 0 by default. Set this
parameter to a value from 0 to 9999 seconds.
Using the BCC
To set the hold down time, navigate to the serial prompt (for example,
box
;
serial/
2/1
) and type:
hold-down-time
integer
For example:
serial/2/1#
hold-down-time 0
Using Site Manager
See the Hold Down Time parameter on page A-83 for information.
Setting the B Channel Override
On AN and ANH routers with ISDN support only, you can connect the ISDN
B channel to a specific serial communications controller (SCC). By default, the
B channel is determined by the connector.
You can use the Sync B Channel Override parameter to specify which B channel
this interface is using for ISDN. Select BCHANNEL1 or BCHANNEL2 to
explicitly assign the B channel.
