Subject: OT: Adtran 550 Setup for Voice CCIE
- All,
This probably isn't as off topic as it
sounds, as some Voice CCIE candidates
will probably be asking the same thing
as they ramp up. . .
Has anyone used an Adtran 550 to perform
voice emulation successfully with either
FXO or PRI's?
* Can a single port be setup for both acting
as "network" meaning that the FXO ports
terminate a connection from the network,
and act as "user" ports which terminate
incoming calls as well for user equipment?
It would be used for incoming or outoing calls just as any FXO port
would. So the 'network' side may have a specific number tied to it
(your phone number) while the 'user' side would have a range 9.whatever
for outgoing calls. Can you plug a telephone into it? Yes. Remember
that an FXO port in Cisco's sense means that the port is functioning as
an FXS device. (relying on the device on the other end to supply
dial-tone, etc.)
* Or do you need two separate ports, one to
act as network, and another to act as user?
The nomenclature is a little misleading. If you are in a lab-only
environment, you can configure things however you want all based on the
user dial-plan that you configure on the Adtran.
* Is a normal RJ11/14 (crossed) used with
FXO's when connected to a VIC-2FXO-M1, or
do you need a straight thru cable?
Just a generic, all-purpose RJ11 cable AFAIK.
* At what point should you see TEI assigned
on a NM-HDV (with VWIC) during the Adtran's
configuration? Awaiting establishment is
about as far as I get.
Not sure on this, I've use my PRIs for data calls on regular T-1 cards
and haven't really paid attention.
* Is there any real difference between the
network and user modules that provide one
or multiple T1/PRI port(s)?
Unless the 550 is different than the 800, the answer is that it just
depends on your configuration. I have an 800Plus unit, so that's what
I'm basing my experiences on. Each can be configured to be what you
want it to be and the difference is based on which side of the game you
are on. If you're connecting to a live telco network, your switch is
being a user. If you're connecting to devices in the lab, your switch
is going to be the network.
For study purposes, which ones would be
best?
