You are adding a remote location to a Communication Manager(CM) 6.2 customer with a duplex system, and G650 media gateways at the core. You want to use H.248 gateway(s). The location will have 30 IP sets, 30 analog sets, and 40 DCP sets. You know that the base G430 gateway includes 32 Touch Tone Receivers (TTRs), and the G450 gateway includes 64 TTRs.
To support all of the sets going off-hook at the same time, how many TTRs will be required, and which hardware would be required to provide the TTRs?
