[asterisk-users] S110M not working

[Noah Miller]

Hi All -

I pulled from a working system a TDM400 with one s110 fxs and three
x100 fxos.  I put it into a new box and the fxs no longer works.  The
fxos work just fine.  I thought it was odd, but I chalked it up to a
random chance failure and ordered another s110.  The replacement
doesn't work either, and now I'm confused.

dahdi_scan recognizes the s110, but it says it fails.  Output looks like this:

[2]
active=yes
alarms=OK
description=Wildcard TDM400P REV E/F Board 5
name=WCTDM/4
manufacturer=Digium
devicetype=Wildcard TDM400P REV E/F
location=PCI Bus 05 Slot 01
basechan=5
totchans=4
irq=169
type=analog
port=5,FXO
port=6,FXO
port=7,FXO
port=8,FXS FAILED

I tried moving both the s110s to other positions on the TDM400, but it
fails in all of them.

Is this a power issue?  The system it's in only has sata power
connectors, so I had to splice on an ide power connector.  Both the 5v
and 12v lines are connected through all the way from the power supply
to the tdm400 card.

If I force the issue, and manually configure the s110 like this:
---------------
fxoks=8
echocanceller=mg2,8
---------------
the dahdi startup script throws this error:

Running dahdi_cfg:  DAHDI_CHANCONFIG failed on channel 8: Invalid argument (22)
Selected signaling not supported
Possible causes:
        FXO signaling is being used on a FXO interface (use a FXS
signaling variant)
        RBS signaling is being used on a E1 CCS span
        Signaling is being assigned to channel 16 of an E1 CAS span


Have I bungled the power connection and/or the config, or am I just
extremely unlucky and have two bad s110s?


Thanks,
Noah
