color:#1F497D'>Since the cheaper phone is only 10/100 a lot of customers have structured
wiring with 3 or more runs to each desk. In the closet they have non-POE
1000BaseT switches for PCs and 10/100BaseT switches for phones with PoE. They
run 10/100 to the phone and 1000 to the PC. The cost of 10/100/1000 PoE
switches is pretty expensive compared to 10/100 PoE. Still one network on
backend just no IP Phones on expensive 1000BaseT ports. This also reduces
SmartNet costs.<o:p></o:p></span></p>

<p class=MsoNormal style='margin-bottom:12.0pt'>So there are two network cables
going from your distribution closet to your desk. One cable to the phone and
one cable to the PC? I want to run one cable, have the phone on the voice
network and PC on the data network. If I have to configure the VLAN manually
that is fine I just want to know if it will work this way. <o:p></o:p></p>

<p class=MsoNormal>Note I said logically separated not physically separated.
Yes you run a cable to your PC and a cable to your phone. You can
do the logical separation at the switch (configure port-based VLANs) or further
downstream if you want a whole switch of just phones and another whole switch
of just PCs... etc. We do not run separate core networks.
Disadvantages?... if we want to connect from pc to the voice network it's
routed (but this is to our advantage because then we have the ability to set up
access lists at the router level). We can't use VT Advantage (not a
concern) and we miss out on some silly click-to-dial stuff that no one in our
organization seems to care much about. Rather, they want a rock-solid
phone system and that's what they get.<br>
<br>
I guess the definition of "converged network" is different for
everyone though.<br>

<p class=MsoNormal style='margin-bottom:12.0pt'>Bill I don't think you
situation is comparable to most. You are not using a converged network which is
one of the big reasons to go with an IPT system. You have two physical networks
one for voice and one for data.<br>
I want to have one physical and two logical networks like I can with
Cisco phones and Cisco switches. The phone boots up and changes to the voice
vlan and the phones are on the data vlan. I don't care to tell the customer
that they must manually configure this but can they still use DHCP for all of
the IP info and just manually set the voice vlan?<br>
ALso if I do this how do I set it up on the HP switch side? Is it a trunk or an
access port with two vlans?<o:p></o:p></p>

We use (have used but are phasing out) HP Procurve on the voice<br>
network. No problem. But note: we have a
logically-separated<br>
voice network, do not use the phone's PC port (thus no need for<br>
VLAN) and have had to deal with power insertion because our HP<br>
switches are not powered.<br>
<br>
CDP is not needed. I don't understand what you mean about
hard-code<br>
the configuration. DHCP provides the options the phone needs
to<br>
contact Call Manager.<br>
<br>
I was watching the other thread about Adtran and some of the stuff<br>
people said seems quite like FUD. Cisco appreciates this<br>
scare-tactic marketing but the truth is that you can use any LAN<br>
switch. Using Cisco gear will make your life easier though.<o:p></o:p></p>
