I'm a bit confused on how to setup Zaptel.conf and Zapata.conf when there is a TDM400P and a TE410P installed after upgrade. The TDM400P has 2 FXS in position 1 & 2 and 1 FXO in the fourth position. I see boot, WCT4xxP loading first and WCFXS loading second. According to my understanding, given above, the TE410P should be configured first, then the TDM400P. However, I'm not sure how to show channels numbers for the FXS Ports. This was working properly before I upgraded to TDM400P (was X100P). But now the TE410P LED's are flashing RED Please Help Bart Here is my current Zaptel.conf: # Span 1: TE4/0/1 "TE410P (PCI) Card 0 Span 1" AMI/D4 span=1,0,0,d4,ami e&m=1-24 # Span 2: TE4/0/2 "TE410P (PCI) Card 0 Span 2" AMI/D4 RED span=2,0,0,d4,ami e&m=25-48 # Span 3: TE4/0/3 "TE410P (PCI) Card 0 Span 3" AMI/D4 RED span=3,0,0,d4,ami e&m=49-72 # Span 4 TE4/0/4 "TE410P (PCI) Card 0 Span 4" AMI/D4 RED span=4,0,0,d4,ami e&m=73-96 # Span 5: WCTDM/0 "Wildcard TDM400P REV E/F Board 1" fxoks=97 fxoks=98 # channel 3, WCTDM, inactive. # channel 4, WCTDM, FXO fxsks=99 And Current Zapata.conf: ; Span 1: TE4/0/1 "TE410P (PCI) Card 0 Span 1" ; This T1 is attached to in-house CUST 3 System ; language=en rxwink=300 usecallerid=yes hidecallerid=no callwaiting=no usecallingpres=yes echocancel=yes echocancelwhenbridged=no echotraining=800 rxgain=0.0 txgain=0.0 immediate=no busydetect=no busycount=15 callprogress=no ;relaxdtmf=yes ;callerid=asreceived faxdetect=incoming signalling =>em_w group = 2 channel => 1-24 ; Span 2: TE4/0/2 "TE410P (PCI) Card 0 Span 2" ; This T1 is attached to inhouse CUST 10 System ; language=en rxwink=300 usecallerid=yes hidecallerid=no callwaiting=no usecallingpres=yes echocancel=yes echocancelwhenbridged=no echotraining=800 rxgain=0.0 txgain=0.0 immediate=no busydetect=no busycount=15 callprogress=no ;relaxdtmf=yes ;callerid=asreceived faxdetect=incoming signalling =>em_w group = 3 channel => 25-48 ; Span 3: TE4/0/3 "TE410P (PCI) Card 0 Span 3" ; This T1 is attached to WorldCom Local 714 DID's language=en context=from-localt1 ; <rxwink=300 usecallerid=yes hidecallerid=no callwaiting=no usecallingpres=yes echocancel=yes echocancelwhenbridged=no echotraining=800 rxgain=0.0 txgain=0.0 immediate=no busydetect=no busycount=15 callprogress=no ;relaxdtmf=yes ;callerid=asreceived faxdetect=incoming signalling =>em_w group = 4 channel => 49-72 ; Span 4 TE4/0/4 "TE410P (PCI) Card 0 Span 4" ; GBX inbound & outbound T1 language=en context=from-tollfree ; <rxwink=300 usecallerid=yes hidecallerid=no callwaiting=no usecallingpres=yes echocancel=yes echocancelwhenbridged=no echotraining=800 rxgain=0.0 txgain=0.0 immediate=no busydetect=no busycount=15 callprogress=no ;relaxdtmf=yes ;callerid=asreceived faxdetect=incoming signalling =>em_w group = 5 channel => 73-96 ; Span 5: WCTDM/0 "Wildcard TDM400P REV E/F Board 1" ; ; Note: this is an extension.
