[VoiceOps] question about campus installations

[Matthew S. Crocker]

I've used a Zhone MALC 319 with 48 port POTS cards running MGCP to an M6 for this exact scenario. It worked great for years, this summer I updated the firmware, switch to SIP and moved the customer onto our Broadworks platform. Still working great. The MALC is a bit of a nightmare to configure but it is great. The MALC I have running has 4 - 48 port POTS cards with a bunch of empty slots. We installed it in a weather proof cabinet including batteries & fusing. This came from Zhone already assembled and wired. Everything is in the basement of one of their campus buildings right next to where the old PBX was. 

To cut over we wired up new Krone blocks for the MALC. Ran cross connects from Phone -> MALC block and double punched MALC block -> PBX block. Left the MALC disconnected on the 25 pair. When it was time for the cut we just yanked off all the double punch xconnects to disconnect the PBX and plugged in the MALC 25 pair. The total outage was a couple minutes to cut 150+ extensions over. 

I also use Zhone MALC XP 150A with ADSL2+/POTS running MGCP to my M6. The ADSL2+ is great to push bandwidth out to dorm rooms if they don't have Cat5 anywhere. You can get DSL modems that are embedded in a single gang faceplate to mount in the dorm rooms. Students would see a Cat5 Ethernet jack with 24/2 mb ADSL2+ on the upstream 

The MALC supports P-phones but no other digital phones.

For digital phones you can use a Citel Portico TVA-D. This will convert digital handsets to SIP. I'm not sure about MGCP. It works with Broadworks, not sure about the M6

> Hey all, i have a question that i could use some help on.

> I have a customer that wants to replace a PBX that is shared between
> administration and residences in a campus environment with a VoIP
> solution. PBX currently has a digital phone in each residence
> connected via CAT3/rj11 back to a RJ21x the MDF. There are 238
> units. customer would like to provide POTs service to each residence
> with some class 5 features, VM, CLID, 3WAY, etc. There is not
> Cat5/rj45 connections in any of the units.

> I was thinking of bringing in several Adit600 chassis, with 5x8port
> FXS cards in each, which would give me 40 FXS ports/chassis. meaning
> 6 chassis. i would likely use MGCP, b/c it works well with the Adit.

> I can't seem to find a better/larger device that does more than 40
> FXS ports, besides a PBX. does anyone know of a product/channel bank
> that can handle more? i can do SIP or MGCP.

> oh, i know that i can get a CAT 6500 and populate it with a couple
> CMMs and populate the CMMs with 24 port FXS cards (
> WS-SVC-CMM-24FXS), but the client can't maintain it.

> I'm running an Broadsoft M6.

> thanks!
