adtran

This should apply to US/North American Adtran TSU 600 + T100P. I've got 6x quad FXO cards, so this may not apply to the FXS models.

In the menuing system of the TSU 600, go to the config section and verify the following settings:
1) Network (NI)

format: ESF
code: B8ZS
yel alarm: ENA
xmit prm: Off
clock source: network
set lbo: 0.0 dB (if cable is short)
Inband Lpbck: ??
Bit Stuffing: ??

7) Port Config
Cycle through all available ports and verify they are FXO+. Mine came shipped from ebay in this mode.
Then hit enter on each one and verify that they are all in FXO_LS mode.

Now plug the T1 Crossover Cable into the "Network" slot in the back of the Adtran unit (I made one myself, it shipped with a staight-through T1). Plug all appropriate telephone cables into the FXO slots in each module, and connect them to the wall outlet.

I'll assume that you've already installed * and it is working from your SIP phones (i.e. you can connect to the sample server).

Edit your /etc/zaptel.conf and add the following lines:

span=1,0,0,esf,b8zs
fxsks=1-24

Edit your /etc/asterisk/zapata.conf and add the following lines (at the bottom):

group=1
context=default
signalling=fxs_ks
channel => 1-24

Now, you'll need make sure that the module is loaded. Do this by typing:

# modprobe zaptel
# modprobe wct1xxp

Verify that things are working by:

# ztcfg -vv

You should see something like:

24 channels configured.

If you want to be able to dial out, then add this to your extensions.conf file:

exten => _91XXXNXXXXXX,1,Dial(Zap/g1/${EXTEN:1})
exten => _9NXXXXXX,1,Dial(Zap/g1/${EXTEN:1})

Now start up asterisk using:

# asterisk -vvvvc

Congratulations! Asterisk should now be working with your new (or gently used) Adtran TSU 600 + Digium T100P.
