Lync 2013 Bandwidth for 50 users (all services)
Hi all,
I am looking into implementing Lync 2013 as our replacement voice system. We currently have 2 ISDN lines "Nortel BCM50", and our current bandwidth is as follows:
Line 1: 16MB Down / 1.5MB Up
Line 2: 16MB Down / 1.5MB Up
Line 3: 5MB Down / 5MB Up
We have 2 external numbers with external calls routing through the 2 ISDN lines currently.
We have 50 users and are looking to use the following services:
External calling
Audio Conferencing
Video Conferencing
Instant messaging (globally)
Lync for Smartphone
Remote assistance
Would anyone be able to advise if our current bandwidth/ISDN system would be up to the job?
Or even if anyone could advise me roughly what Internet speeds we need (upload and download) for all Lync services for 50 users?
Any help at all would be massively appreciated!

Yes and I inputted "Bandwidth" and "users" field only like it says you can do for a rough calculation. It came up with a green tick stating "% of internet link 24%".
Im having a hard time trusting it though as BT told me my bandwidth wasnt enough (Though it was a sales person who wants to sell me their own cloud hosted Lync).
Im basically looking to see if there is anything off the bat that would prevent me from going down the road of having on-premises Lync.

Based on running the bandwidth tool with the information you provided it indicated that Line 3 has enough bandwidth to support 50 users with a standard usage profile while Lines 1 & 2 are weak in the UP bandwidth but good in the down bandwidth.
To answer your statement Sean, I see no reason why you could not go with on prem Lync as long as you have the hardware to support it. You'll need to design a decent system. My recommendation would be 2 FE's in a pool, 2 ED in a pool minimum. This will give you some semblance of HA with two servers vs one server in the pool. A single Director and a single Mediation server should suffice (I prefer to not colo the mediation server on the front end server.) For presentations you'll also need an OWApp server as well.

Wow ok, thats a lot of servers! We were looking to purchase a new Proliant Server with VMware and virtualize our servers. Do you think a single VMhost machine would suffice to host all of these servers?
Dependent upon the server. If it can provide the required number of VM's at the minimum hardware specs then yes, you'll be fine. In our environment, all of our servers are VM's.
Well, I think you need to do more requirement gathering.
How many total users?
Is HA a requirement if yes for Internal and External service?
Load balancing DNS or HLB is there one existing in the infrastructure?
Is there an existing Reverse proxy infrastructure that can be used by Lync?
Public IP's depending on the Edge design it may be 3, 6 or 9
Public UCC certificate for Edge use
If you are talking Voice/Video then QOS
Bandwidth requirements
PSTN connectivity do you already have a supported gateway or pbx?
