Using T1 WIC with Drop and insert. Correct application??

rodekholm · ‎04-20-2012

I am crossing a couple of platforms and technologies, and I want to understand if I can make something work. Traditionally, in Telecom and more specifically 2-way radio systems, we use a MUX'ing device that takes the individual timeslots (DS0's) and mux them up to a T1/DS1. Well, it's the 21st century, and we want to start moving forward to the IP Systems, as they offer some great features.

So here's my scenario and question. I have 4 sites that all connect in a SPUR type of configuration. Full T1 goes to site A, drops 6 ds0's, then passes the remaining 18 ds0's onto site B. Site B keeps 6 DS0's, and passes the remaining 12 onto 2 other site that spur from it. Can I do this with voice grade, Drop and Insert versions of the T1 WIC?

Here is a picture of what i'm trying to achieve.

Thoughts, ideas, comments or anything else that may help me would be appreciated!!

And thatnk you in advance...

Also, if there is another application/device that will do this, please let me know as well. Our thoughts or hopes were to use either a 2800 series router or possibly a CGR Series.

The best approach would be that you engage a reputable consultant, or UC certified Cisco partner.

Designing and implementing LMR systems is not easy, an the details of doing that are largely ouside the scopt of a mostly practical user forum like this.

While I appreciate the pitch for a cusultants pocket, I want to know if it is possible. I'm not asking for someone to do a config. I'm asking if this scenario is possible, before I go and as our folks to make it happen.

Thank you.

Yes, it's possible. However, it is more efficient, simpler and economical, to full VoIP rather than drop and insert.
