ZESA Configuration

[Beauty1982]

Hi to everybody!

I have a CS1K 5.5 with Geographic Redundancy (3 sites, one main and 2 BO), The BOs has their own routes to PSTN, and I would like to use ZESA in order to send the emergency calls to the PSTN according to the BO that is making the call, every BO has a different zone assigned.

Can you help me? I don't know if I have to change translation tables or only use LD 117 and LD 24, but I don't know exactly how.

Can sombody post a configuration?

Regards, have a nice day.

Thanks in advance

Is this one switch or 3?
How do the BO's use there own routes to PSTN?




This is a Signature and not part of the answer, it appears on every reply.

This is an Analogy so don't take it personally as some have.

Why change the engine if all you need is to change the spark plugs.

They're 3 switches but according to the Geographical redundancy, they seem like a node.
All the configuration is set in the main, and the database is replicated among them.
The BO have the PSTN routes, not the main.

If you figure this out, I'll be pleased to hear of it. I installed one of these systems and discovered the same problem.

the Zone based Emergency Services Access (ZESa) is not intended to provide alternate routing by zone. It's intended only to provide a solution to E911 issues created by spreading your node across a large geographic area.

Nortel, when I inquired with them, indicated that zone-based alternate route selection is not a feature available in the CS1000, and if you want this, then you would be better to go for a multi-node environment and not a geographic redundant or branch office configuration.

The problem stems from the fact that each node has one BARS configuration, and everyone uses the BARS configuration at the main site.

ZESA is not in Release 5.00 and 5.50. It has been replaced by ESCM/ESA enhancements that route and modify CLID based on the ERL values.

Suggest you hire some help here. (I'm currently booked through September)

Sorry, I misread the original post. Apparently reading is not among my skills today. However, although ZESA shows up in the 5.0 documentation, it seems pointless to hack out the relevant sections since he's talking about a 5.5 installation.

I actually helped Fletch edit and review the ESA NTPs last year some time. I'll probably see him today or this weekend and I'll let him know that he missed pulling that stuff out.
