The Hicom PBXs need to be using a combination of either FXO <--> FXS or E&M <--> E&M. If they are doing digital signaling then T1 CAS (e.g. wink start) will also work. If they are doing ISDN based signaling then this will also work but you would need to use the Transparent CCS feature which is a different configuration.
Are you using Frame Relay on the 3810s serial ports and if so what is the bandwidth? Where are the 4 uncompressed voice channels? Are you talking about logical voice streams across the Frame or are you referring to channels on a fractional E-1 to the PBX (on the POTS side)?
If the 256K to which you are referring is on the Frame Relay link two things are true, first unless you take steps to reserve a portion of the bandwidth for voice all of the link bandwidth is up for grabs, and second if you do reserve 256K for voice the remaining will be available for data.
Yes, I will be using Frame Relay on the serial side.
The leased line is 512k.
The PBX installer wants 4 uncompressed channels from the the E1 at either PBX to be carried across the serial link to allow for full feature transparency so that for example, calls can be handled at either site when the other site is unmanned.
General guidelines for what you need on the Frame side.
1. Use LLQ (Low Latency Queuing) to allocate bandwidth to voice through a priority queue.
2. You will have to identify voice packets for LLQ through either IP/UDP port number or packet precedence.
3. You will need approximately 83K per voice call at G.711. This means that you will have to allocate more than 256K for voice. You might try cRTP (RTP header compression) to pickup some bandwidth. This should reduce bandwidth requirements 40K per call but some Cisco bandwidth charts show 68K as being required (I dont know why).
4. In any event you should not allocate more than 75% of the physical speed of the link in LLQ (a Cisco guideline) to voice and data combined.
5. You will need to specify codecs of G.711 on the dial peers at each side of the Frame connection.
6. The remaining bandwidth on the Frame connection should default to WFQ. You can insure this by specifying it in your LLQ configuration.
I recommend trying G.729. You might want to do a test asking the users which they prefer and not telling them which test uses which codec.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
