Setup =====
- Running on a Dell Server. - RedHat 8 - Asterisk 1.0 - I have two TE410Ps on that box, card 0 assigned to IRQ 4 and card 1 assigned to IRQ 3. - The rotary switch on both cards is set to 0. - I have tried setting the switch on card 1 to other than 0, but it does not work (what is the switch for??) - Both cards have 3 E1 spans and one T1, both in the same order. - Card 0 has worked well for months, and works well even now that card 1 is installed. - zttool finds the 2 cards.
Interrupts are as follows:
CPU0 0: 1382239 XT-PIC timer 1: 4177 XT-PIC keyboard 2: 0 XT-PIC cascade 3: 2659119 XT-PIC t4xxp 4: 2659098 XT-PIC t4xxp 8: 1 XT-PIC rtc 10: 200713 XT-PIC eth0, eth1 11: 0 XT-PIC ide2 12: 20 XT-PIC PS/2 Mouse 14: 12541 XT-PIC ide0 NMI: 1 ERR: 0
Problems ========
- Choppy voice on calls between channels of card 1. - Even worse on calls between card 0 and card 1. - Card 0 behaves well. - IRQ misses for card 1. Have tried different interrupts. Same thing. - HDLC overrun messages on console for card 1.
Strange fact, may be the cause of the problem =============================================
Configuration for first span on card 1 is:
span=5,1,0,ccs,hdb3 bchan=118-132 dchan=133 bchan=134-148
However, zttool reports card as "Internally Clocked". No matter how I've tried, I cannot get card 1 to clock from the external source:
Sync Source: Internally clocked
First span on card 0 is configured just the same:
span=1,1,0,ccs,hdb3 bchan=1-15 dchan=16 bchan=17-31
This card gets clocked OK: Sync Source: TE410P (PCI) Card 0 Span 1
Thanks in advance
Fernando
