Hi,

I came across very interesting question from one of my Client on the above. When i was explaining the benefits of IPT migration, i narrated that ENterprise Survivability is possible in IP Enabled system like S87XX systems. If a server is down, then IP Phones will automatically register to the other Gateway connected to ESS or Survivable server at other location.

Customer questioned me if the same possible in TDM systems also? and also asked if Digital Phones too can get connected in the same way? Is there any technology can do the same?

I don't know how far this question is correct?

Any Help on this please?

With regards

Avaya does have survivability in a traditional Definity G3r only, if they still sell it. But it is different than survivability on an IP switch. This works for remote EPNs (that is why it is G3r only). The difference is that the entire remote EPN will cut over to a G3si carrier colocated and connected to the remote EPN.

To make this work successfully the remote EPN must be self sufficient when installed. It must have local trunks for calling out and receiving calls, if there are any announcements they must be on a local announcement board. When making changes to this remote EPN there are two places that changes need to be made. In the G3r for that EPN and in the standby G3si located with the EPN. You need to keep track of where everything is. If the programming does not match, if it cuts over then there will be problems.

Of the handful of these EPNs that I installed the remote EPN was always a single carrier G3si style EPN, never an MCC cabinet (different slot count).

I did some reading on a G250-Analog gateway, they also have a G250-BRI, G250-DCS, and a G250-DS1. The G250-DCS supports digital stations and just like other G250 gateways it can register to up to 4 MGCs. If Avaya wins our RFP we would be using the G250-Analog gateways in very small locations with the built-in PoE ports for 8 IP phones. I believe that the G250-DCS will support 24 digital stations.

The G250-Analog supports 4 CO trunks, 2 analog stations and 8 IP stations.
