NAME
xpp_sync - Handle sync selection of Xorcom Astribanks.SYNOPSIS
xpp_sync [auto|dahdi|nn]DESCRIPTION
On a normal operation one Astribank device provides timing for all the other Astribank devices.When run without parameters, xpp_sync will display a list of Astribanks (xbuses) that are connected and registered as Dahdi spans. The current xpp sync master will be marked.
If you this an Astribank is connected and yet it does not appear on the output of xpp_sync, it may be unregistered. Try running dahdi_registration .
Parameters
- auto
- Automatically selects the best Astribank for syncing.
- dahdi
- Gets synchronization from the Dahdi sync master.
- nn
- Sets XBUS-nn as sync source.
(Parameter name is case-insensitive)
Example output:
Setting SYNC Current sync: 01 Best Available Syncers: + XBUS-01 (usb-0000:00:10.4-3) [usb:12345678] [ PRI_TE PRI_NT PRI_TE PRI_NT ] XBUS-00 (usb-0000:00:10.4-2) [usb:QA-01] [ FXS FXO ] ================================================== WARNING: FXO which is not the syncer cause bad PCM Affected Astribanks are: -------------------------------------------------- XBUS-00 ==================================================
In this example we see that the recommended xpp sync master is XBUS-02 - it is the first on the list. It is also the actual syncer, as we can see from the '+' beside it.
xpp_sync is normally called from the dahdi init.d script. The parameter it is called with defaults to auto, but it is possible to override that parameter (e.g: set it to dahdi) through the value of XPP_SYNC in /etc/dahdi/init.conf .
FILES
- /proc/xpp/sync
- xpp_sync is essentially a nicer interface to /proc/xpp/sync . That file shows the current xpp sync master (and in what format you need to write to it to set the master).
