Panasonic KX-TAW848
I just installed my first one of these today, and at Gary's request, here's my take on it:
First Impressions
Prior to ordering, my first impression was how confusing all of the optional cards are to plan out and implement. The 848 uses three different sizes of card slots and each size slot is designed for a variety of different expansion cards. It is very important to plan out both the current and future uses of the system as each card array contains a very limited amount of expansion cards. For instance, the medium sized card slots will accomidate either 4 CO or 4 Hybrid extension cards with a maximum of 4 cards per chassis. The large card slots will support either 8 port SLT cards, 8 port proprietary extension cards, etc. Without having the installation manual, you'll easily pull all of your hair out trying to determine how many cards you'll need and be able to support.
Upon unpacking, I noticed several nice improvements over the 624 systems.
Cable management has been improved
The removable cover is now large enough that you no longer have to whittle out the top of it to fit standard 3.5mm jacks for page out and music on hold
The transformer now includes screw holes for wall mounting it. No more staples and wire ties to hang the transformer!
Included is a memory card for backing up your programming
Gone is the 4-inch high loose stack of installation, programming and user manuals. They've now been replaced by three seperate bound manuals.
Also included is a tutorial CD and a programming software CD.
Installation
I have to admit to reading over the installation manual while I was driving with the manual in one hand, a doughnut in the other and the steering wheel lodged between my knees. The installation manual is written in easy to understand language and thourough without being TOO thourough.
After arriving at the job site, I was able to install the CO, Extension and Caller ID cards in less then 10 minutes. Everything fit very nicely and nothing left me scratching my head.
The supplied template and screws gave me no problems with mounting the 848 on a plywood wall (unlike the very unfriendly Panamax that I mounted next to it).
After doing some punching down and UTP termination, I was feeling pretty confident in myself that it was going to be an easy day.
Programming
As was mentioned in a previous post, Panasonic has radically changed bot the way that the system is programmed and many of the terminology has changed too. The 848 is big into "groups", which will probably throw you off a bit first, but after you dig deeper into the features, you'll realize that the groups can be very powerful tools.
After booting up the software, I was miraculously able to connect to the 858 via RS232 on the very first attempt (null modem cable required). Many of the features that litterally took hours to program on a 624 can now be done in a matter of minutes by using the software.
However, because of the sophistication with the 848, there's going to be more then just a couple of drill down items in the software that you're going to look at and think "hmmm, I wonder what the hell this is for?". Fortunately, in my case, the defaults worked in most cases.
Within a couple of hours, I had the system pretty well programmed to do what I needed it to do for this application. I should also point out that this was installed into a busy office environment that is fairly feature demanding.
After customizing the programming for each extension and enabling call logging, I distributed the user manual for each of the KXT7731 telephones on each of the user's desks. At one point, I needed to refer to the 7731's user's manual when I noticed that OOOPS, the manuals don't yet include support for the 848, and the 848 operates much differently then the older models of KSU's therefore rendering the station user's guides mostly useless.
Now here's where the real fun began
VPS integration
This system was sold with a TVS-50 Voice Mail Processor. The 848 brags of having powerful digital integration with Panasonic's VPS's. HOWEVER, there is absolutely NO details in either the 848's installation or programming manuals on how to do it. I then refered to horridly written PDF documentation that comes with the TVS-50, and unfortunately, when it was written, there was no 848 system, so there's no mention on integration with one of them.
After nearly two hours of trial and error, I finally found the proper configuration of the TVS50, which would allow it to properly communicate with the 848. Panasonic really, really should have immediately issued addendums to the TVS50's manual to include support for the 848. I lost valuable time having to figure all of it out by myself.
Summary
After glueing back the hair that I'd pulled out trying to integrate the voice mail, I found the system to be extradinarily powerful. I didn't use any of the wireless phones, so I can't comment on them, but overall, when compared to the 624, hands down no contest, this thing rocks.

I've only done a few houses with the 848/7680, but I can say WOW! Great coverage, and seamless handoffs...

0How are the things that all phone systems seem to get wrong in the residential market? Namely caller ID logging, executive override, paging and such?

0I'm in the middle of my first 848 installation right now, so I'll report back on that question in a week or two.
The client found the manuals on line somewhere and now has a long, long list of features he wants to add to the system. He was annoyed with me that my guys didn't finish up the basic installation on Friday, yet he had them chasing around changing ring tones for him. Go figure. He will be paying T&M on the feature changes, so that may damp his enthusiasm for bells & whistles!

0I found it by trial and error. What I did was go into the TVS-50's quick setup feature and tried all of the six or seven PBX options that are listed. Since the 848 uses digital integration, none of the analog options (624, etc.) will work.
Unfortunately, I don't have the system in front of me, but if memory serves, the setting that works is either the 4th or 5th one listed. I want to say that it's for the 308, but don't hold me to it. The setting that works is definitely for one of the digital PBX's.
The other thing that you need to do (and you've no doubt seen this in the study guide) is to use the 848's maintanence program to change the VPS extensions from the default phone setting to VPS (this is done in the Configuration/Extension drop down menu). If you've got the TVS-50 properly configured, the 848's software will immediately show the VPS ports as having a VPS connected to them (after you place the extension port back in service).
If you don't have the TVS50 properly configured, then the 848 will show the VPS ports as "fault" as soon as you put them back online.
I hope this helps, and I feel your pain.

0AHEM,
Many thanks. We're headed out there this morning to continue, so I'll make sure and try this, and will report back.

0I was told that the new units would work with Service Provided Voice Mail - or phone company vm. Does it? If you have a Service Provided Voice Mail does the message light work when someone leaves a message?
I think this is a great feature for resi if it works.

0I can't rule it out, but I can't imagine how it would work.
