2250 DB25F to RJ45 to Bix and the various jumpers

[dabble]

I have a 2250 console connected to a CS1000E at Rls 6 that I would like to be able to move to different workstations as the need arises.

At each of our workstations we have quad RJ45 CAT5 jacks going back to a cabinet.

For extending our digital phones to the workstations, from the QCBIX1A block from the PBX, I jumper the TN's to another bix that is 100 pair CAT3 cable to the cabinet punched down in RJ45 panels. I then connect a patch cord from the workstation jack to the appropriate corresponding pair.

This works for a normal digital phone.

I have a DB25F to RJ45 adapter (part # 29-0810-01) connected to the back of the console, and the CAT5 patch cable connected to a wall jack.

My question then, is how would I jumper the 2250 consoles on the various bix?

I don't necessarily need the power TN's as the distance is within the 3000ft.

I have checked out Mike's PBX Cookbook link for the 2250 console wiring, but I think I am missing something.

Somehow I guess, I need to get the two TN's down to the one pair on the bix that goes to the cabinet, I think......not really sure.

Thanks for any assistance.

2 TNs will require 2 pairs (4 wires)


not sure what you mean by :

"Somehow I guess, I need to get the two TN's down to the one pair on the bix that goes to the cabinet, I think......not really sure."

Yes, I think my issue was having only a single pair (2 wire) to the jack that I needed to patch to the workstation jack. So if I take another pair and punch it to the same jack i would then have the 2 pairs I need. I'll try that next week. thanks.

Where did the 3000 foot rule come from? That statement is incorrect. There is no guarantee the consoles will work for 300 feet without power. They might - but all console wiring should include power TNs.

Refer to page 50 of NN43001-567_05.03 Telephones and Consoles Fundamentals:

Normal operating ranges
The Avaya 2250 Attendant Console has a maximum permissible loop length of 3500 ft (915 m), assuming 24 AWG (0.5 mm) wire with no bridge taps. A 15.5 dB loss at 256 kHz defines the loop length limit.

Yes, but this statement is incorrect "I don't necessarily need the power TN's as the distance is within the 3000ft."

OK Thanks. I will be sure to use the power TN's then. Thanks.
