Hi all, I have a problem on starting the ISDN PRI T1 line using on Wildcard T400P.It keeps saying the D-Channel of the span is down after T200 timeup and sending SADME and receive DM from network side. How can I start the D-Channel? I have checked with the network side and matched with their framing and coding. # ztcfg -vvv root@voicetest03 log]# ztcfg -vvv Zaptel Configuration ===================== SPAN 1: ESF/B8ZS Build-out: 0 db (CSU)/0-133 feet (DSX-1) Channel map: Channel 01: Individual Clear channel (Default) (Slaves: 01) Channel 02: Individual Clear channel (Default) (Slaves: 02) Channel 03: Individual Clear channel (Default) (Slaves: 03) Channel 04: Individual Clear channel (Default) (Slaves: 04) Channel 05: Individual Clear channel (Default) (Slaves: 05) Channel 06: Individual Clear channel (Default) (Slaves: 06) Channel 07: Individual Clear channel (Default) (Slaves: 07) Channel 08: Individual Clear channel (Default) (Slaves: 08) Channel 09: Individual Clear channel (Default) (Slaves: 09) Channel 10: Individual Clear channel (Default) (Slaves: 10) Channel 11: Individual Clear channel (Default) (Slaves: 11) Channel 12: Individual Clear channel (Default) (Slaves: 12) Channel 13: Individual Clear channel (Default) (Slaves: 13) Channel 14: Individual Clear channel (Default) (Slaves: 14) Channel 15: Individual Clear channel (Default) (Slaves: 15) Channel 16: Individual Clear channel (Default) (Slaves: 16) Channel 17: Individual Clear channel (Default) (Slaves: 17) Channel 18: Individual Clear channel (Default) (Slaves: 18) Channel 19: Individual Clear channel (Default) (Slaves: 19) Channel 20: Individual Clear channel (Default) (Slaves: 20) Channel 21: Individual Clear channel (Default) (Slaves: 21) Channel 22: Individual Clear channel (Default) (Slaves: 22) Channel 23: Individual Clear channel (Default) (Slaves: 23) Channel 24: HDLC with FCS check (Default) (Slaves: 24) 24 channels configured. # dmesg PCI: Found IRQ 10 for device 02:09.0 Detected Tormenta 2 Quad T1/PRI or E1/PRA at 0x40100000/0x40200000 irq 10 fwload: Init and done gone to low fwload: Init went high (clearing done) Now loading... fwload: Transferred 69884 bytes into chip fwload: Loading done!
