Re: Point to Point

No, you don't need a router that splits the T1 into 2 ports. You use
subnetting. The ideal setup for systems like that is to keep the phones in a
different subnet with its own switch. We always set it up this way - not
only for the voice quality but also for security purpose. Phones are
relatively easy to hack. You would set it up like this:
A location phones 192.168.100.x
B location phones 192.168.101.x
A location computer LAN 192.168.200.x
B location computer LAN 192.168.201.x

When you do the PtP T1 you configure the router with static routes to route
the traffic through the T1 pipe. Depending on where you terminate the pipe
(phone or LAN) you add a little DLink or something to use for the gateway to
the second subnet.

Let me know if this makes sense to you or if you want me to draw a little
diagram.

the good news is mys customer wants to keep the phone support separate
from
the network support. I say good news because I have no experience with
VOIP.
I do have lots of networking experience but never VOIP. I am sure it is a
simple application of TCP/IP but since i have no experience I don't want
to
start with thios customer. My job will be to provide a router on 1 side.
Site A is getting a 24 port T1 router with 12 telco lines and 12 data
lines
tomorrow. Sometime later a point to point T1 will be run to Site2 (like
in
the next couple of weeks). They intend to share the same phone #'s and
want
phone routing between the two sites. They will be sharing a software
program
that will reside on a server at Site2 so we will need a router that splits
the T1 to two different ports one for the phone lines and one for data. I
will need to make sure the router will work for 5 phones connecting to
site
1. The data side will then be run to the linksys switch.

Am I making sense?

A point to point T1 is just that. 1.544MB data transfer. I'm not quite

what you mean by "5 phone lines and 1 data line". Normally the telco
company
providing a point to point is just providing the jacks and you have to
supply the routers. So it's up to you what routers you use. One of the
more
cost effective ones are Adtran with a T1 interface.

I assume that the phones are VoIP - because otherwise this wouldn't work.
The networking part is easy. Just use a different subnet at the remote
site
and add some static routes. The tricky part are the VoIP phones. In order
to
help you there I would need to know what VoIP gateway system you are
using.
Are there currently VoIP phones at HQ? If yes, what is the address
schema?

Give me some more info and I will be able to point you into the right
direction.

I have a client who is looking to do point to point about 3o miles
apart.

At one site (Site A)they are already getting 12 phone lines and 12 data
lines via T1 and are running with a file server and 7 users.

On the other site (Site B) they will be bringing in a point to point T1
line
from the first site with 5 phone lines and 1 data. They are running a
SBS
server with Exchange in operation and 7 users. They will be maintaining
a
DSL
line for Internet on this site.

They are hoping to keep SBS functioning and add the users from the
first
location to the second.

My thought was to bring the point to point from site A through a router
into
Site B's existing Linksys 2024 switch. The router would break the voice
lines
over to their telco controller and the data line to the Linksys switch.
This
would then put all the users from Site A to Site B and allow me to add
them
to the existence network.

Any surprises I should be aware of? What router is recommended for Site
B?
Any SBS limitations that will hinder this?

My knowledge of voice over IP is not fantastic so bear with me if I am
asking stupid questions here.
