Can I use multiple T1 and V.35 cards in the same Linux host?

Yes. In order to configure multiple T1/E1 or V.35 WAN cards, you must manually configure the PCI slot and bus configuration of each wanpipe card. You can find out the slot and bus information using the /usr/sbin/wanrouter hwprobe command. 

[root@oakbank wanpipe]# /usr/sbin/wanrouter hwprobe

1. S514-7-PCI : SLOT=8 : BUS=2 : IRQ=10 : CPU=A : PORT=PRI
2. S514-7-PCI : SLOT=8 : BUS=2 : IRQ=10 : CPU=B : PORT=PRI
3. S514-1-PCI : SLOT=7 : BUS=2 : IRQ=11 : CPU=A : PORT=PRI
4. S514-1-PCI : SLOT=7 : BUS=2 : IRQ=11 : CPU=A : PORT=SEC

Using /usr/sbin/wancfg, set the AUTO_PCISLOT setting to no and configure the PCISLOT and PCIBUS settings for you card. Repeat this for each card configuration.
