Adit 600 - Getting Dial Tone
Hello, I have an Adit 600 (3 FXS cards) hooked up to a digium T1 card in my
asterisk box. I 'connected' the slots to the a:1 T1 interfaces via the
command line. The slots (3 fxs) are configured with 'ls' signaling. I
configured the T1 card with the same line settings as the T1 interfaces on
the adit and I get green lights on both the T1 card and the T1 interface on
the adit (so

Adit Asterisk Cabling Connundrum.
I am hoping to replace my Nortel 8x24 switch with
Asterisk. Right now my cabling comes from my outside
phone box into my office and into a punchdown block
and leaves the punchdown block as an amphenol
connector which currently plugs into the Nortel
swicth. A second amphenol connector them plugs into
the switch and extends to another punchdown block that
I believe carries the lines throughout the

Rhino Channel Bank or ADIT 600
I am forklifting a Merridian option 51c with 112 Nortel Digital Handsets
and 400 analog units. For the analog units I have quotes for 9 ADIT 600
48 port fxs units and 17 Rhino 24 port FXS channel banks. I have used
neither. Which is the best choice? The price difference is not that
great. I am looking at Citelinks 24 port Handset Gateway for the Nortel
Digital units. (Any other suggestions

[Fwd: Re: Adit 600 channel bank in UK setting]
Jon,
I actually had some more discussions with Tim on this issue, and it seems that the channel bank
would still be a good option to choose for internal purposes. I would not see any other solution
than a channel bank to connect many 2wire phones into one asterisk box. I had a talk today with
Carrier Access, and it seems that the adit would do us fine. The fxs cards of the adit 600 are

Adit 600 over MGCP.
Hi,
Anybody out there running Adit600s?
I have in my care an Adit600 channel bank connected to an old (version
1.0.6) Asterisk instance with MGCP. When trying a more recent Asterisk
(1.4.21.2~dfsg-3+lenny1, Stock current Debian) calls fail.
I have attempted to add the "slowsequence = yes" line to mgcp.conf. (It
seemed to be the only likely candidate in the example files I found

Carrier Access Access Bank 1, incomming calls only echo problems, and Adit 600
I am a little confused about the FXO ports on the Carrier Accesss Bank
1. The wiki, and people on the mailing list have stated that they do not
have impedance matching, but Carrier Access states in their
documentation that they do have impednace matching. Did Carrier Access
make a typo, or does it depend on the version of the FXO card?

DTMF detection with Adit 600
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
It seems like Asterisk are having problems detecting DTMF digits when
using an Adit 600 channel bank via MGCP.
I've tried to turn on RFC 2833 on both Adit and Asterisk, but no
digits at all are working then.
Anyone experienced simular with Adit or other channel banks?
I'm also unable to use V.90 modem through my setup (Adit600 via MGCP

Does anyone know what I need to put in the mgcp.conf to connect to an

BT / X100P impedance matching
I understand that the X100P card is matched to a 600 ohm impedance but the
UK BT phone system is not (I haven't been able to find much information on
the impedance of the UK system).
Has anyone come up with an easy way to match the impedance between the two
so the X100P can work in the UK? Presumably a simple transformer won't do
the job since it won't pass the DC components?

FXS channel banks
Greetings list,
I've been asked to provide a system for 200 extensions, most of which will be existing analogue POTS handsets, not IP handsets. I've not really had any experience with large channel banks in the past (since most of our deployments are strictly IP-only to the desk), so I'm at a loss as to which ones are worth looking at.
If anyone's had experience using channel

Callerid on t1 lines
Hello All,
Just a question, I have an adit600 and I am looking for a way to pull
the incoming cid into asterisk.
Does anyone know if this is just not possible via t1? Or is it only
available on PRI?
Thanks,
Greg

Channel Bank Echo
We are a voip terminating company, we're using Channelbank with FXS
modules, Rhino, CAC, etc.. What we're wondering is, is how to would you
echo cancel a channelbank. Of course we're realizing that cancel'ing on
the T1 (on Ast) does no good (we think?) because the analog conversion
is at the channelbank. Suggestions? Lowering the gain helps but we're
looking for a real solution

- 40 phones and only 3 PSTN trunks?. I would recommend at least 2 BRIs
for this. If you have ISDN you can also get DDI to the extensions.I
would strongly recommend abandoning the analogue PSTN lines and using
ISDN. The setup pain you will go through will be significantly less,
combined with better audio, more features (like DDI numbers!) and much
more robust connections.

Problems with ADIT600 and T100P
I am having trouble getting my T100P and ADIT 600 talking. I have 2 FXO

Fax/Modem, Asterisk, Channel Banks
I've been replacing an old Toshiba DK switch with an Asterisk solution. I'm
needing a solution for fax machines that works as well as a POTS line from
my carrier. If the POTS line is the solution, I'll keep it, but I'd rather
move away from that.
Here's what I'm thinking...will it work?
I would use a dual-port Digium T1 card. In one port, I'd terminate a telco

Rhino cards lock up system -- anyone else ever seen this?
Hi Folks,
Struggling with a new * installation with 2 Rhino R2T1 cards. For some
reason, the system is locking up tight when you run ztcfg to configure the
card(s). Configuration is asterisk 1.2.14, zaptel 1.2.12, and rhino's
1.05rxt1 drivers. The cards seem to load fine with a "modprobe rxt1",
but once
you run "ztcfg -vvv", the system will lock up within a few seconds, no

CAC ADIT600 / T400 config
I know a few ppl have those CAC Adit 600's with t400
I can't seem to get my second span up on the T400
connected to the second spand on the adit (A:2)
A:1 seems ok
Can someone post they zaptel.conf span defintions
And maybe a "print config" from the adit 600 cli
I think my issue is timing srcs the coding, framing. bld out are all matched

FXS vs. FXO
Hello,
I've recently purchased Adit 600 with 3FXS and 1FXO to be connected to
my * server via T100P card. This is the output of "status equipment"
command in the Adit600:
For some reason the FXO card is seen as FXS, why? Is it ok? On the card
it is written "FXO".
