Solved: VGC248 - 60+ analogs phones !!!

Fernando_Meza · ‎05-28-2008

Hi netpros,

Here is the scenario. A customer is running CCM on head quarters. One of his satellite locations currently using PABX will me migrated to CCM. The client wants to keep using 60+ analog phones on the satellite location. Am I correct in looking at the VGC 248 gateway for this purpose ..?

Your input is much appreciated !!!

Hi Fernando,

Excellent question here! We use a number of VG248's that supply 48 Analog ports per device, and really like the product.The VG248's are really great to install and they ship with an excellent step by step guide. Have a look at these docs that explain the Hardware and Software components of the install;

The way that they "wire out" with RJ21 25 pair cables really fits nicely into most wiring infrastructures.

You can order most any length of pre-made 25pr cable that will connect to the Front Panel of the VG248 and can be routed right to the existing cross-connect (punch down blocks) or you can terminate (on punch down blocks, Bix,110 Blocks,R266) the VG248 25 pr cables in a Central location and run a new Tie Cable or Cables to the existing cross-connect. The "old" Analog circuits can be traced and new connctions to the VG248 can easily replace them pair for pair, circuit for circuit. This is nice for a "phased" approach :)

We have migrated hundreds of Analog lines from Nortel to the VG248 in just this manner. Using the type of cable listed below;

That being said, many people feel that the VG248 may be announced as EoL sometime in the near future (as yet they have not been EoL'd)

I have not seen an EOS/EOL notice for the VG248;

So the other choice is the newer VG224, they wire out the same way etc. They have half the ports :)

Hope this helps!

Hi Rob,

I really appreciate your detailed explanation. It was exactly what I was looking for .. specially the wiring part as I was not sure how the connections were to be "linked". I will definetely have a look at those documents.

Cheers,
