BCM50 Expansion

[mrplacid]

I have a BCM50 currently with 1 expansion chassis containing a Digital Trunk Interface. I need additional extensions but also 5 analogue extensions (modems/fax's). If I add another expansion chassis (I believe I am limited to 2?) would it be best to add a digital extension interface and then 5 x ATA or an ASM for the analogue extensions and IP Phones instead of the digital extensions? Any advice would be much appreciated.

There is the availability of 4 analog ext. on the main unit,2 are there already the other 2 ports are unlocked by keycodes. I would use a DTM 16 in another expansion chasis and 1 ATA plus the 4 analog ext.'s that reside on the main unit. If you are using them already,I would use 5 ATA's with a DSM16. I don't see an advatage to using ip sets over digital, unless you have remote users.

Thank You! I can now see from the RJ21 wiring diagram that there are 4 analogue telpehone connections. I have connected an analogue telephone to device 5 (DN 233 Port 413) but it is dead. Am I missing something?

you need a key code to inable it

there are 2 different ones

NTKC0238 BCM50 Analog Station - 2 Port Authorization Code
NTKC0239 BCM50 Analog Station - 4 Port Authorization Code

TIP :

If you have newer generation of fax , you probably would get problem with old ATA so you might want to use the internal analog which can handle faster baud rate than the old ATA .

Do you need CLID or OSI generation? If so then the ATA won't supply those features. The on board ports will and so will the GASM.

I am told that these key codes are only compatible with v2. I believe I have v1? (bcm_m50r1 1.00.2.04.j) Is this correct and if so, is it just a software issue that can be upgraded or is it the physical hardware? Thanks

 

[BombOne]

you can upgrade the software to 2.0. A vendor should be able to tell you if those keycodes are compatable with 1.0, those are the part numbers I've been using for a while, but they have been 2.0 systems.

Also Im sure there are keycodes for the same thing on 1.0

 

[RPMcMurphy]

Are the keycodes different between the 1.0 and 2.0 systems? How would you tell by looking at the keycode? Under the NT part number there is a Release xxx, is that the version the keycode is compatible with? Or does that mean something else?

 

[mrplacid]

I am told by my vendor that the codes are only compatible with v2 and even if I was to upgrade the software to v2, my hardware will not support the built in analogue extensions! They have suggested that I upgrade the software to v2 and then install a digital/analogue extension combi card. Any thoughts on this? Thanks

You need to find a new vendor. First, the keycodes work for either version. There aren't keycodes specific to version 1 or version 2, just bcm50. Second, there isn't a digital/analog combination card for the bcm.
