[Freeswitch-users] TDM400P spans

[Jeremy Johnson]

I'm trying to convert from Asterisk to Freeswitch, and have a question about spans.

I read the freetdm configuration example for TDM400 
and am wondering what exactly is a span.

I have 2 TDM400P cards in my computer, 
one card has 2 FXS modules for connecting analog phones. 
The other card has 3 FXO modules for connecting to  3 PSTN trunk lines.

# lsdahdi 
### Span  1: WCTDM/4 "Wildcard TDM400P REV I Board 5" 
  1 FXS        FXOKS       (In use) (EC: OSLEC - INACTIVE)  
  2 FXS        FXOKS       (In use) (EC: OSLEC - INACTIVE)  
  3 unknown    Reserved     
  4 unknown    Reserved     
### Span  2: WCTDM/4 "Wildcard TDM400P REV I Board 5" (MASTER) 
  5 FXO        FXSKS       (In use) (EC: OSLEC - INACTIVE)  
  6 FXO        FXSKS       (In use) (EC: OSLEC - INACTIVE)  
  7 FXO        FXSKS       (In use) (EC: OSLEC - INACTIVE)  
  8 unknown    Reserved

Do I configure freetdm as in the example for TDM400 
with separate spans for each module like the following?
or should I have just two spans as shown by lsdahsi?
Thanks.


#cat freetdm.conf
