NAME

6       xpp_sync - Handle sync selection of Xorcom Astribanks.
7

SYNOPSIS

9       xpp_sync [auto|dahdi|nn]
10

DESCRIPTION

12       On a normal operation one Astribank device provides timing for all the
13       other Astribank devices.
14
15       When run without parameters, xpp_sync will display a list of Astribanks
16       (xbuses) that are connected and registered as Dahdi spans. The current
17       xpp sync master will be marked.
18
19       If you this an Astribank is connected and yet it does not appear on the
20       output of xpp_sync, it may be unregistered. Try running
21       dahdi_registration .
22
23   Parameters
24       auto
25           Automatically selects the best Astribank for syncing.
26
27       dahdi
28           Gets synchronization from the Dahdi sync master.
29
30       nn  Sets XBUS-nn as sync source.
31
32       (Parameter name is case-insensitive)

34   Example output:
35               Setting SYNC
36               Current sync: 01
37               Best Available Syncers:
38                + XBUS-01 (usb-0000:00:10.4-3) [usb:12345678]       [ PRI_TE PRI_NT PRI_TE PRI_NT ]
39                  XBUS-00 (usb-0000:00:10.4-2) [usb:QA-01]          [ FXS FXO ]
40               ==================================================
41               WARNING: FXO which is not the syncer cause bad PCM
42                        Affected Astribanks are:
43               --------------------------------------------------
44                       XBUS-00
45               ==================================================
46
47       In this example we see that the recommended xpp sync master is XBUS-02
48       - it is the first on the list. It is also the actual syncer, as we can
49       see from the '+' beside it.
50
51       xpp_sync is normally called from the dahdi init.d script.  The
52       parameter it is called with defaults to auto, but it is possible to
53       override that parameter (e.g: set it to dahdi) through the value of
54       XPP_SYNC in /etc/dahdi/init.conf .

FILES

57       /proc/xpp/sync
58           xpp_sync is essentially a nicer interface to /proc/xpp/sync . That
59           file shows the current xpp sync master (and in what format you need
60           to write to it to set the master).
