Legend Networking 1

[PhoneTechMan]

I've two Legends, R7 in my lab that I'd like to network together. I understand that you need the 100D's in both switches. I've never networked two Merlins before and wondered if anyone might have a cheat sheet for the basic setup. A post or email will be fine. Thanks in advance.

This will get you started.

I threw this together kind of last minute, so if anyone out there sees corrections or additions that need to be made, go ahead. Then we can post a final under the FAQ.

Networking two Merlin Legend or Merlin Magix systems using UDP(uniform dial plan).

You must use Legend Rel 6.0 or higher to network, but it is recommended to use 6.1 or higher in order to take advantage of centralized voice mail.

Each system must be equipped with a DS1 card to handle the point to point T-1. CSU is preferred but not required. Although the system will handle using a partial T-1 for voice, leaving the remainder for data using an optional CSU/DSU, this guide will cover installation based on using the entire T-1, and assume that there are no additional PRI T-1s in either system.

*If you have an existing PBX, and you adding a remote location, it will save you time and troubleshooting if you are able to co-locate both systems for the purpose of programming and testing. This way, you are sure your programming works prior to having to deal with any LEC issues concerning the point to point. For testing purposes, using a cross-over cable will simulate a point to point T-1. Remember to use a T-1 crossover and not a standard Cat 5 crossover.

Install the DS1 card in each system. Set both card to PRI. Use ESF and B8ZS as your frame format and suppression.

Once this has been done, the following will need to be done to each system. There is no specific order, but following this guide will help you keep track of programming.

1. Set the switch type of each system. Under PRI, Switch Type, set the main PBX, which will be referred to as Switch A to Legend-PBX. Set the other PBX, Switch B, to Legend-Ntwk.

2. Set the switch number of each system. Under Lines Trunks, UDP, SWNum-Single. Set Switch A to 21, set Switch B to 22.


3. Assign the B channels to each system’s B-Channel Group. Under PRI, B-ChannelGrp, B Channels. Use B-Channel Group number 80 for both systems. It is recommended that you assign them in reverse order. For example, if your T-1 card is in slot 4, then your B-Channels are 0401 through 0423. Assign them starting at 0423, 0422, and so on.

4. Then you must assign the corresponding lines to each system’s B-Channel Group. Under PRI, B-ChannelGrp, Lines. Assign the lines to group number 80. Remember to account for lines in front of the T-1 card. For example, if you T-1 card is in slot 4, and there are 408 cards in slots 1-3, then your starting line number would be 813.

5. Assign the corresponding lines to a line pool. You can use any pool available, but starting at the last pool, 899, and working back will leave the other pools available for standard lines.

6. Now you must setup your UDP (uniform dial plan) routing. Switch A must have a different extension dial plan than Switch B. Using a 4-digit number plan is recommended. For our example, we will use 1000 series extensions for Switch A and 2000 series extensions for Switch B. Under each system, SysRenumber, Non Local UDP, define each Non Local UDP. It will be the other systems extension numbers.

7. Now set up your UDP routing in each system. Under Tables, UDP Routing, Pools, enter the appropriate pool number(899 if you followed the example). You will not need to redefine the FRL level unless you have modified the default ARS tables or you plan to make outbound calls across the the network using the other PBX as the carrier. You will not need to make any digit settings.
