Hello

I was wondering if its possible to expand beyond 3 cabinets on any samsung system? The system currently in use is the idcs 500 Release 1 which would be the preference.

If its not possible to expand beyond 3 cabinets, would it be possible to locally link 2 idcs 500 system in the same office without using the VOIP which is design to connect 2 system remotely?

Please let me know if either on these 2 options are viable.

Thanks for your help.

Hi WalkerTexasRanger,
3 Cabs is the max that you can link off of the one processor.
You can link multiple systems together also with QSIG using TEPRI cards and this will give increased features over linking with VoIP.
If you upgrade the processor cards to Rel2 then you will have the same features linking with VoIP.

Best bet would be to do what Tailor says and upgrade to Release 2 and link them via IP networking. Using QSIG you won't have as much features cross systems as you would with IP networking though they would both give you cross system dialing. Plus once you network them via IP you could expand to 99 systems, (don't think that will ever be done) though Samsung before they swapped out to the 7200 had quite a few 500's networked together in Texas.

Both ways are very good. The cheepest way would be the T1 route. Hook up the cards back to back no impact to the local network. You will have to address the voicemail issue since you will be in a network. I would centralize the VM that way you don't have to deal with network mailboxes and local boxes. It's a pain! All the features would work indicators and the transfer of messages between the nodes. You can't network a Rel 1. All software and hardware will need to match on both systems. There is a lot to it, but not that much. Also watch out for the rel 1 to rel 2 conversion...check your database after

Can you let me know the physical equipment needed for this setup?

Each system will need 1 additional TE/PRI card dedicated to network the systems?

What physical cable connection is used to connect both TE/PRI cards? A standard CAT 5 cable?

Does the VOIP method on the Release 2 system use a different interface card than the TE/PRI card?(maybe the SMGI3 card?)

This is for a very large building but everything is local in the same phone room. (This is not linking remote offices across the country but rather 2 systems next to each other)

Thanks for your help!

Convince the customer that IP networking is the way to go. If it is really to be used and made to be one system even though they are not IP networking is going to make it seem that way. With QSIG you will not get things like BLF's between systems and a slue of other normal features. If they are on the cheap side then I guess with QSIG you can get by with cross system dialing.

benb... :bow: is 100% correct. Like everything $$ comes into play. If you do IP then you need MGI cards in both systems and IP's from the network so you will need some idea about the amount of TDM to IP conversion regarding your trunking and if your going to do that, then add in e-gateway too...nice!

Not sure I agree with all the posts here.
IP does have it's advantages but it's going to be costly. You will have to upgrade the 4 processor cards you already have and then start on the other system and buy MGI cards.
Even then you will only have 16 channels of OK quality as opposed to 30 channels of perfect quality.
If you go down the QSIG route then you will use a TEPRI card in each system and link them with a CATV wired with the PRI pairs crossed.
This does work Rev 1 to Rev 2 but maybe that's unsupported in the US?
Feature wise you will have desk to desk dialing, barge-in, call back, centralised voicemail and operator either way. With IP you will have the addition of Page and BLF keys.
There are more pro's and con's but these are the main ones.
If you can go IP then you will have better future proofing and will be able to link other systems and share the MGI channels as well as use them for IP Phones (Local or Remote), Softphone, Wireless IP, SIP and H323.
If Money really isn't an issue then look at installing a 7400. The only thing you will be able to reuse is the phones but you will have one system and the ultimate in future proofing.

Listen to Benb go rel. 2 on your Samsung system and you solve ALL problems and even more. Think chipper … your choice .. .Keep going on Saundance crew listen guys . :bang:

Couple of things to think about:
- If the IP network goes down, IP link is dead
- QSIG uses a T1 to T1 patch cable directly connected
- US only rel 2 to rel 2 and all other software must match in the network (T1, LCP, SCP, MCP)
- Software upgrades. Samsung sometimes messes up and creates problems in their IP code so IP networking could be exposed.
- 7400 WEBMMC is a pig. The switch is really good and the data side is cool! The 64 channels in the main cabinet for multiple MGI64's or 2TEPRI card is a definate plus

Ideal best way is use both. Use IP as 1st choice and if it goes down or needs to overflow you have the T1 QSIG for backup or reverse it. The quality on the IP is cell phone. You now have the ability to test or use either application or remove 1 from the trunk group and only use your choice. Like he said, pro's and con's....
