24 Lines on FXO ?? HELP !!!

[Gezimvatovci]

I have c3945 voice bundle platform, i'm looking to connect 24 lines on Router.

c3945 can support only 3FXO all 12 ports but i need to connect 24 ??

If i want to use E1 card like HWIC-1CE1T1-PRI how to connect all those lines on E1, one side is RJ45 other side ??

do i need to use any converter how to connect all lines ??  what kind of cable to use from E1 module to those lines. ?

Please find me a solution to connect all 24 analog lines on c3945.


 analog lines ----- > c3945 ----- > phones

 Thanks a lot,

GV

You will need to use EM-HDA-6FXO cards. Refer to below post for details:

FXO and FXS use the RJ-11 connector. FXO is used for termintaing lines coming from your Telco. The phones will terminate on switch, connected to the router. If you are asking you want to plug phones as well on same router them you will need switch module (but that may limit the number of FXO ports due to space it will take.
