Environment:CentOS 5.5Attachments:( 0) 0001-dahdi_genconf-Use-dahdi_scan-to-determine-span_type-.patch

Description:I have port 2 jumpered as TE, ports 1,3 and 4 are set to NT.

Here is the system.conf that dahdi_genconf generated, I also have a 2 span PRI card installed so that why the span numbering starts at 3 for the B410P:


# Span 3: B4/0/1 "B4XXP (PCI) Card 0 Span 1" (MASTER) AMI/CCS
span=3,3,0,ccs,ami
# termtype: te
bchan=63-64
hardhdlc=65
echocanceller=mg2,63-64

# Span 4: B4/0/2 "B4XXP (PCI) Card 0 Span 2" AMI/CCS
span=4,4,0,ccs,ami
# termtype: te
bchan=66-67
hardhdlc=68
echocanceller=mg2,66-67

# Span 5: B4/0/3 "B4XXP (PCI) Card 0 Span 3"
span=5,5,0,ccs,ami
# termtype: te
bchan=69-70
hardhdlc=71
echocanceller=mg2,69-70

# Span 6: B4/0/4 "B4XXP (PCI) Card 0 Span 4"
span=6,6,0,ccs,ami
# termtype: te
bchan=72-73
hardhdlc=74
echocanceller=mg2,72-73

This problem can be easily resolved: the wcb4xxp driver must expose NT/TE mode in span.desc (like other drivers do) and _xpp/perl_modules/Dahdi/Span.pm_ must be adapted to read the information from the span description.

See attached patch.

It would break the interface in 2.5 (which the output of /proc/dahdi/x is part of) to add the NT|TE strings the span description.

What about the attached patch "0001-dahdi_genconf-Use-dahdi_scan-to-determine-span_type-.patch" which uses the output from dahdi_scan to determine TE|NT mode for the B410P driver?  Something like this I believe could be released on the 2.5 branch.

I have tested 0001-dahdi_genconf-Use-dahdi_scan-to-determine-span_type-.patch:

dmesg shows the following configuration for the B410P:

wcb4xxp 0000:05:01.0: Identified Wildcard B410P (controller rev 1) at 00011000, IRQ 74
wcb4xxp 0000:05:01.0: VPM 0/1 init: chip ver 33
wcb4xxp 0000:05:01.0: VPM 1/1 init: chip ver 33
wcb4xxp 0000:05:01.0: Hardware echo cancellation enabled.
wcb4xxp 0000:05:01.0: Port 1: NT mode
wcb4xxp 0000:05:01.0: Port 2: TE mode
wcb4xxp 0000:05:01.0: Port 3: TE mode
wcb4xxp 0000:05:01.0: Port 4: NT mode

dahdi_genconf now generates /etc/dahdi/system.conf with correct
span configuration for NT ports:
