How many IP licenses can I add?

[pjevnisek]

I've got a BCM400 with an expansion chassis running release 4.0. Here's how the busses are allocated.

2 - DSM32+
3 - DSM32+
4 - Trunk module (from 4x16)
5 - Station module (from 4x16)
6 - ASM8
7 - DTM

DS30 split is 2/6

We currently have 31 IP client licenses and need to add another 22. Can the system support that as it is?
Your feedback would be appreciated.

This info below could be out of date?.

The BCM400 is a 4-bay system.

Without expansion, this unit is capable of 30 channel Isdn and 96 digital handsets. You can increase the telephony with the use of IP handsets.

If installed with an Expansion module which allows for another 6-bays, with 30 channel Isdn you can have 160 digital handsets. On top of this, you could also have 58 IP handsets (configuration allowing).

All the best

If it's working, then leave it alone!.

In terms of adding additional IP sets, refer to BCM 4.0 Networking Configuration Guide, chapter 5 "Rules for managing the resources", in particular "Signaling channel rules". Adding another 22 sets would increase your signalling channel requirements by 22.

If you have a 2/6 DS30 split, the total number of signaling channels is 64.
If you have a 3/5 DS30 split, the total number of signaling channels is 96.

It all depends on what else you are doing on the BCM, for example Dial-on-Demand ISDN WAN uses 27 signaling channels. So if you are using this, 27 + existing IP 31 + additional 22 IP sets > 64 on a 2/6 split.

Refer to this document and ensure you have sufficient signalling channels, on a 2/6 split. Otherwise a 3/5 split however you won't be able to use bus 7 for DTM. Perhaps you need to bite the bullet and look at a 450 with CEC allowing total of 300 sets (without CEC max 100 sets) otherwise.

Thanks for your guidance pkellow.
