mCC5500 NO LONGER SUPPORTS MIXED MODE?

[Radiogeek97]

FOLKS
My department is working on replacing all of our infrastructure (micor based) and CCII console. We are in the process of dealing with the aces team and ironing out the quote ect. My salesperson sprung on me today that because we are working towards a mixed mode system and not strictly conventional system with no plans of digital the Mcc5500 is no longer capable of doing this. I was told that motorola has had supply chain problems with the digital interface for the 5500 and thus they are no longer reccomending it for mixed mode systems. My salesperson told me that we need to move up to a mcc75oo console with a gateway module to accomplish what we want. The system basically has one main site and two recievers, one of which is the back up repeater/reciever. We also have a second channel that is stand alone (msr) no voters. What we planned is to replace all the recievers with quantars flashed for p25 all the repeaters (including the stand alone) will be P25 quantars. The comparitor (astro tac) as well as the necessary modems. I have been told that the quantars have been given a final order date of this coming sept.
Any suggestions will be appreciated. I was under the impression that the mcc7500 was a trunking only console I could be wrong. Any pointers help would be appreciated


thanks

The 7500 is the only new dispatch offering beyond Gold Elite which supports trunking, however it is not 'trunking only'. Like Elite, it's a full dispatch solution. That said, it's a big price jump over the 5500. I don't know if your sales guy is snowing you or not, I haven't heard of any troubles with the 5500, but then again we haven't dealt with them at all. Maybe someone else can chime in with more info for you.

I trust the sales guy as far as the information he is giving me, i used to work with him at another M dealership before I pinned on the badge again. That being said he may have been given bull crap info from his regional moto guy or this moto "aces" team. I guess the crux of the problem is there is that the digital interface for the mcc5500 is NLA according to my salesperson M had problems with the supplier and is not offering the digital interface for the mcc5500 which in our configuration would not work "suposedly"
As far as the price I think a single position mcc5500 is around 100K +or- what prices are you seeing for a Mcc7500??

anybody with any further info on the interface unit availability? I will try to contact motorola myself what should I be asking for exactly? I refer to this as a digital interface? Does anybody have any part numbers ect that i can throw out to motorola when i do call?

I have seen a couple of the MCC5500 units installed recently that have both analog and digital interfaces on them. On one system, they used the MIP-5000 units to go from the digital interface (IP) to an analog radio circuit (one analog port per unit). The other one was just installed over the last 3 months or so and uses the CCGW rack mounted unit as the analog interface (4 analog ports per unit).

My money is on the Motorola sales force trying to maximize their share of the bounty for the new system. Sounds like you need to be more forceful in the approach of talking with them. Maybe another approach would be to look at another vendor for the console. That is a good way to get the attention of the Motorola sales force. If you haven't figured it out yet, you can't spend any more money on a console than with Motorola.

Eh Jim - They are using CCGW interfaces on MCC 5500? Or are you thinking of 7500 (which I would expect to see CCGW's on).

GGM 8000's coming out real fast to replace the CCGW/DCCGW on MCC 7500... More ports & it'll decode MDC, redundant power supplies, etc.

While the 5500 does not support direct trunking system connection, it never has. It will work with xtl consolettes for trunking control bases as well as any conventional resources. I have installed 5 mcc5500 systems and never heard of a digital interface, the only digital connection the 5500 is capable of is a sb9600 connection to a xtl consolette or other control base and all DAP's are capable of it, it just needs an ibutton to activate it. They are full of it.

In this case the 5500 will not be used in a trunking enviorment at all. What we want to do is since all of our infrastruture wont pass the narrowband mandate we want to build out the backbone as P25 and when money comes available we can replace flash the mobiles/portables for digital. So basically the new mcc5500 will be wire lined to out two channels channel 1 is has 3 recivers and channel 2 is a stand alone repeater. From what I was told there is no way to have the mcc5500 wire lined to a mixed mode capable backbone because of this mysterious interface unit that is NLA. I know we could tie the console to an xtl consolette but i tont like that set up I would prefer positive wire line control over the system not a 100k console tied to our repeaters via an rf link. I was told that the mcc can do conventional only digital only but it "supposedly" cant exist in a mixed mode conventional/digital (non trunked) system anymore ?? Our M dealer also sells zetron but i would prefer moto. That being said we could go to another M dealer in our area But most of them arent worth a dam

[Batwings21]

Ok, so it sounds like this mystery interface is maybe a DIU?

[Batwings21]

Also I don't see how a 7500 is going to do this without using control bases which a 5500 can also do.

[Radiogeek97]

batwings yes i think that is exactly what the salesperson said id NLA i belive he did indeed refer to it as a DIU. The question now is is there a part number for the diu and that way there i can call moto. Anticipating one step further if indeed this diu is not available is there anything else or any way else to get around using one? What exactly does this diu do?

[Batwings21]

The DIU is a analog on the console side and digital v.24 data on the radio side. They are used for converting the analog audio from the console to IMBE digital to be sent to the quantar as data. On the other side it takes receive audio as data from the quantar and turns it into the analog audio that is sent to the console. It also handles the encryption if used. However I don't think a 7500 can do analog and digital mixed mode using a direct interface to the repeater or comparator without a DIU.

Sure. DCCGW or GGM 8000 allow 7500 to do this.
