Hello All-

Our network recently was rebuilt and the Merlin Messaging IP Address is now no longer on the subnet of the new network. I am attempting to access the administration interface through a serial connection. I have found documentation that requires a 355AF adapter, DB25 to DB9 adapter, and a D8W (or ethernet) cable. Unfortunately, I do not have access to any of these. What I do have, however is a Cisco console cable that has an RJ-45 on one end and a DB-9F on the other. Has anyone used one of these cables to connect to the Merlin Messaging system? I have tried unsuccessfully and I am trying to determine if it is the cable or the HyperTerminal connection. Any assistance is greatly appreciated!

Thanks in Advance.

It's the cable. You need the 355A/355AF adaptor for it to work. You can either make one or buy one for about $35. Here's a post on how to make it yourself:

The pin out sequence is:
Mod Plug to 25 DB
= To Avaya 355AF adapter
1 blue to 22
2 orange to 5, 6, 8
3 black to 20
4 red to 7
5 green to 3
6 yellow to 2
7 brown not used
8 white not used

Mod Plug to 9 DB
= To Avaya 355AF adapter to DB 9
1 blue to 9
2 orange to 1, 6, 8
3 black to 4
4 red to 5
5 green to 2
6 yellow to 3
7 brown not used
8 white not used
 
There are a couple FAQ's here on Tek-Tips about making this cable too..

Does anyone know what the pinout is from the 355af adapter to the admin port of the phone system? I know that a standard straight through patch cord works however I also know that you do not need all 8 conductors (I believe that you only need 4) I need to extend a connection over a 50PR feeder cable and this would help tremendously! Thank you for your help!
