Hello, Looking for information about cabling and possibly cards. Customer has system which is being ripped out. Replacing the unit and hopefully using existing cabling. There are 515 analog extensions in use. From photos there looks to be 5 cabinets/modules stacked. Unfortunately they did not remove the front panel therefor unable to see what cards are installed. Each cabinet has approx 15 cables on the rear. Look to be 25pr Amphenol cables. When we install our equipment we will have 22-23 units with 24 ports on a single amphenol cable. Therefor using 22-23 existing cables. Minimum downtime. This will obviously mean moving jumpers. Depending on the analog cards installed, either 8 or 16 port. Searches suggest 16 port cards with message waiting (site is hotel).
Approx 50 existing cables will not be used. It could be that each room may have had at one time 2 lines per room. Hence the number of cables.
Questions:
1. Gender of cables. Hard to make out but looking at an empty slot the PBX the PBX is female expecting a male cable.
2. Are the cables full 25pr Amphenol.
3. Best guess the type of analog extension cards.
Any information would be appreciated.

1 - <<<Yes -- the cabinets will be female on the back. Gateways too - female.
2 - Probably. I'm assuming you are asking how many lines exist per card -- it will depend on the model of the phone. Maximum will be 24 ports per cable.
3 - What?

Can you clarify more of what is going on here, ie are you moving this customer to a non-Avaya system, or is this an Avaya->Avaya upgrade?
 
wow not a bad install you shouldn't have much to do as you can reuse all existing cable, do you know what the software level is at? a list config will tell you how many ports the cards are, make sue you have the maintenance log in and password from previous customer

 
Swapping to a non Avaya system. Hosted system. Polycom admin users and analog gateways for guest rooms. Depending on analog card types will decide how many jumpers to move using existing cabling. Analog gateways are 24 port units. Perfect scenario would be 24 port cards on Avaya System. To date we have not been that lucky with Mitel,Avaya or Nortel. Close but not quite. Also never really had much luck in getting passwords or a report of old systems.
 
If someone opens the doors to the cabinets and gets the 'TN' number for the circuit packs that will tell you the quantity of ports:

TN742 = 8 ports
TN746 = 16 ports
TN793 = 24 ports

You can alo tell by looking at the labeling on the wallfield:

TN742 allocates 3 pairs/port
TN746 uses pairs 1-4, 9-16, & 21-24
TN793 uses pairs 1-24

Not sure why you would rip out a perfectly good Avaya Definity system when you are using analog phones.
These systems are solid as a rock and last for years.

dumping configurations and local or remote access are not so difficult to get working.

Tinga1... What types of reports? Any BP should be able to dump most of the switch into excel files. ASA can also dump alot of good information.

 
Re: rip out. Not my call. Chain of hotels making changes. Have been sent pics of systems and all look to be similar and all look to be very well installed. Not like some of the jobs we come across. Great cabling makes for easy transition. Downtime during cutover is related to card types in the "old" pbx. 8 port card means moving 2/3 or cross connects.16 port 1/3 of cross connects. 24 port 0.
Most time consuming time is pre-ctover. Not familiar with systems we port map all analog port by setting up a digital (CID) extension and call from each analog station on the block from the PBX and map accordingly. 2 techs. We then config the gateways to match blocks/cables and use existing cabling. Usually means a lot of cabling "could" be ripped out as most hotels these days do not need 2 lines per room.
I agree that these systems run for a very long time and are great for the hotels. Usually we get reports from customers that system is being continually repaired and time to replace. This does not seem to be the case. Cloud based SIP with analogue gateways is the way they are looking at.
