I am having some trouble in locating network addressing prerequisites for SBA deployments. My main question is that to deploy an SBA successfully do the branch and head office sites need to be on different network addressing schemes, for example:
Head Office: 192.168.10.0/24
Branch Office: 192.168.11.0/24
I have already deployed an SBA where the above addressing scheme was true, however in environments where customer has their LAN extended between sites, through a LES circuit for example, will be SBA function as intended? I assume it would, but I cannot find any supporting documentation regarding network addressing in such a scenario. Any feedback would be much appreciated.

It depend on your networkconfiguration. In Lync Networkconfiguration you can configure different Subnet as the real Subnetting.
The SBA will always work, maybe only Medibaypass will not work if the Lync Endpoints are in a different Site as the Gateway.

thanks for the response. Am I correct in assuming if my Lync Standard Edition server in my head office is on IP address 192.168.10.1/24 and my SBA at my branch site is on 192.168.10.2/24 , for example, the functionality of the SBA will operate correctly? Any feedback would be much appreciated.

We recommend you to deploy a DHCP server at each branch site to enable clients to obtain IP addresses.
As an alternative to deploying a DHCP server at each branch site, enable Microsoft Lync Server 2010 DHCP on the Survivable Branch Appliance or Survivable Branch Server by using the Lync Server Management Shell cmdlet Set-CsRegistrarConfiguration -enableddhcp $true.

thanks for the feedback. What I am looking to find out if possible, is whether the SBA and Front End server can be be on the same IP addressing scheme or do they need to be on different subnets for example? Any feeedback would be much appreciated.

If you are talking about the functionality of this as a backup registrar (or primary for your branch users) and PSTN gateway then the subnet does not matter. The subnet only comes into play with things like CAC and supporting media bypass for your PSTN calls. As far as Lync is concerned both the FE Pool and the SBS or SBA can be in the same IP range.
