#Update firmware on Shark model cards to revision 25 or higher. Check out the ((Sangoma Firmware Update Procedure)).
#Edit /etc/wanpipe/wanpipeX.conf for each E1/T1 port. Find the [[wXg1] section where X is the wanpipe number. The MTU variable control the size of the packets in octets delivered to the API. Changing this value also affects the rate of interrupts to the CPU. Less interrupts with more data is a more efficient arrangement for most SMG systems. The values for MTU can be:
**8 corresponding to a 1ms interrupt rate
**16 - 2 ms
**40 - 5 ms
**80 - 10 ms (~~#FF0000:It is recommedend that only the value of 80 be used.~~)
