[cisco-voip] Catalyst 6500 switch as Voice Gateway

[Lelio Fulgenzi]

Don't think you're gonna get 60 FXO ports on a 3845. 

http://www.cisco.com/en/US/customer/products/ps5855/products_qanda_item0900aecd8016c487.shtml

2 x EVM-HDs with two 6FXOs give 12 FXOs (plus 8FXS/DID if you can use them).

4 NM-HDs with 4FXOs gives 16 FXO

4 HWIC slots with 4 FXOs gives 16FXO

44 FXO at most from what I can see.


You're better off convincing them to go with digital. Worse comes to worse you can use seperate RTM groups for each LDN coming into the trunk so each line can only accept one call.

    sure, you can use the CMM modules with FXO or PRI ports.

    take a serious look at comparing the cost of the blades with an ISR though.

    you'll be surprised as to how much cheaper it can be.

    and you'll get to use the ISR for all sorts of other stuff like SRST. granted you can use the CMM for SRST but it is limited in memory.
