25 IP sets in remote location

[lewmar]

Hi,
I would like to get an advice. What would be a minimum bandwith required to connect 25 i2004 IP sets in remote location to the BCM400 R4.0 in main location? Are 2 BCMs connected via voip trunks better solution? What would be a minimum number of trunks and minimum bandwith required in that case?
Thank you.

I can't answer the specific bandwith ?, but I can assure you, acquire another BCM; if only a BCM50. If for no other reason than local copper backup.

To answer the bandwith question there are several questions that need to be asked.

1. How many concurrent calls would you expect to make on the link.

2. What codec will you be using G.711 or G.729

3. If the allocated bandwith is exceeded would you want the link to be busyed out, reduce the codec or overflow over the pstn ?

Basically, worst case scenario G.711 approx 64Kbs bandwith assuming constant talking.

for 911 and survivability go with a BCM50 at the remote site.

Yes, use a bcm 50 with digital phones. It will be cheaper, more flexible, and more reliable. As previously stated, you will need at least 1 local line connected to it for 911.
