Hi,

1. Is there any manual entry about modprobe’s options relative to a given
Dahdi driver (wctdm24xxp, for instance) ?

2. When loading a wctdm24xxp driver, is there any parameter to pass to
modprobe to configure a span in NT/point to point mode ?

3. After running dahdi_cfg -vvvvv , I can read with dmesg :

[ 1986.289277] wctdm24xxp 0000:04:06.0: xhfc: Configuring port 0 span 1 in
TE mode with termination resistance ENABLED
[ 1986.337269] wctdm24xxp 0000:04:06.0: xhfc: Configuring port 2 span 2 in
TE mode with termination resistance ENABLED
[ 1986.385269] wctdm24xxp 0000:04:06.0: xhfc: Configuring port 1 span 3 in
TE mode with termination resistance ENABLED
[ 1986.433269] wctdm24xxp 0000:04:06.0: xhfc: Configuring port 3 span 4 in
TE mode with termination resistance ENABLED

dahdi_cfg itself output is :
# dahdi_cfg -vvvvvvvvvv
DAHDI Tools Version – 2.4.0

DAHDI Version: 2.4.0
Echo Canceller(s): OSLEC
Configuration
======================

SPAN 1: CCS/ AMI Build-out: 0 db (CSU)/0-133 feet (DSX-1)
SPAN 2: CCS/ AMI Build-out: 0 db (CSU)/0-133 feet (DSX-1)
SPAN 3: CCS/ AMI Build-out: 0 db (CSU)/0-133 feet (DSX-1)
SPAN 4: CCS/ AMI Build-out: 0 db (CSU)/0-133 feet (DSX-1)

Channel map:

Channel 01: Clear channel (Default) (Echo Canceler: oslec) (Slaves: 01)
Channel 02: Clear channel (Default) (Echo Canceler: oslec) (Slaves: 02)
Channel 03: Hardware assisted D-channel (Default) (Echo Canceler: none)
(Slaves: 03)

The trouble is before that, I hand edited /etc/dahdi/system.conf with :
# Span 1: WCBRI/0/0 “HA8-0000 Board 1” (MASTER)
span=1,0,0,ccs,ami,term,te
# termtype: te
bchan=1-2
hardhdlc=3
echocanceller=oslec,1-2

What I should I change in system.conf to configure a span in NT mode ?

Regards
