Digital extenders

[thenke]

I need to know if anyone has found another supplier then
MCK, to use as a digital extender from main office to remote several blocks away. Or does someone have good solution for connection to offices together.
Thanks Tom Henke

MCK is all I've ever used and it works very well. I've never had any problems with them other than losing the T1 link from Pac Bell, but as you know that's not an MCK issue. The people over at MCK are very helpful also, they will walk you through setting the units up if you need them to.

I recently took a pair of MCK 8 port 6000 series Extenders out of a customers site, and they are for sale if in need anyone. They are in excellent shape and work excellent.....

joey,

I know we're not supposed to do business on here, but email me how much you're asking for them I'm just curious.

Digital extenders are simply to strech the signal farther then the KSU's capabilties.
To hook two systems together I suggest a couple OPX circuits from your Telco and two ATA's and two CO ports on the KSU's...this will enable you to have 2 callers talking between both buildings at the same time.Call comes in on one KSU and person who answered can transfer the call to the ATA which then travels down the OPX out on the street and rings into the CO port. I would have the second OPX setup the same way but in reverse so that the other building could do the same with its calls if needed.
If you need more then 2 callers and use of features then I suggest you get TIE lines from the Telco and purchase E&M cards for the KSU's....much more expensive though.

Thanks for the response.

I have used OPX lines for the past 15 years. However, I was wanting to set up about 20-24 phones at the remote office. 24 persons from Host office moving to remote office.
I like the MCK solution, becasue it allows me to use the same extension numbers, DID numbers, voice mail, paging system, to the outside world, these 25 engineers are still in the corporate office, plus their calls out will still go across the T1 for reduced LD rates.

I have been using single digital extenders from Nortel and
Ascend Communications for about 6 yrs, but it only allows for one phone extension.

I will check into the Tie line issues, since I have a 12 port CO line module that is spare since moving to our T1 several years ago.

Thanks again, good website

Thenke,

You started off this thread asking if there were alternatives to MCK. Was this for informational purposes or are you having some sort of problem with these boxes? ALso, what kind of connection do you have between your main and branch office? If it is a point to point T1 you can configure the MCKs to use VOIP and easily put 24 conversations on with the addition of 2 inexpensive routers (1 at each end). If you do it this way, you bypass the 12 port limit of the 6000's without the use of additional CSU's or channel banks and with QoS routers you can even support data via the same pipe while giving your voice customers top priority. As you will own both ends of the pipe you can assure excellent voice quality at all times.

Do you have Fiber connectivity between the two sites?
If you do you could look at using fiber extenders and remoting two Station Modules (0X16)'s JerryReeve

Anyone know if the multimode fibre can be muxed into fast Ethernet and back again? In other terms a Fibre-over-IP FOIP gateway?

Thanks again for the respone.
Unable to do the fiber extenders from Nortel. Not a campus environment, two offices are about 3 blocks away, including
2 major streets, and LEC has no fiber down our block yet
(LEC quoted $15,000.00 just to install)

I thought about wireless, but it is just as expensive as fiber, I can get a Point to Point T1 from LEC for $221.00
per month, This is less then me installing 5-6 local analog
lines for these users. ($60.00 per line)

I am already doing Voiceover IP with our cisco routers
to 4 remote office in other states.
I understand what salo0920 is stating about VOIP on the
MCK 6000, but I am not sure it will let the users see
date and time, voicemail access, and full fuctionality
that they are getting now when connected to system.

I Do not have any MCK's at this time, so this was an information question only.

Here was what I decided to do

Buy MCK PBX gateway II with T1 wic
But MCK 7000 extender with T1 wic
Both units support 24 ditital phones

At the remote site, there will be no other phone system or
analog lines.

24 7208, 7310 phones will go with users when they move, they will keep same extensions and features, Calls interoffice will be the same for all locations, remote office will use host PBX for local callings, long distance,
etc.
TO all outside persons, it will appear that they are still
located in corpoarate office.


TO: Salo0920.... If you have setup a MCK 6000 with VOIP, and have 24 phones setup on a fract T1, (12lines) then let
me? But since I have a T1 in place for data, and will have
this other for voice, I am leaning toward the 7000 solution

Thanks
Tom

Thenke,

You might want to email me directly about this. You can reach me at harry@mserve.com.

In answer to your questions, with any of the MCK product(s)you will have FULL functionality at the remote end (with IP or non IP connections). This will include full use of the 7310 LCD display, all features including the time and VM and Feature codes. You can reloc your users just as if they were in your main office.

Tom,
Don't forget to consider how 911 emergency calls will be handled. The MCK 6000 has an analog port option.
