TE412P as PointoPoint Data link over 4E1 for 8Mb Data Link

Hi,

Trying to configure TE412P as point to point data link over 4E1 for 4x2=8Mb data service combinely . But I am getting only 2Mb data bandwidth with those 4E1.

Here is below config what I did …

/etc/zaptel.conf

span = 1,0,0,ccs,hdb3

span = 2,0,0,ccs,hdb3

span = 3,0,0,ccs,hdb3

span = 4,0,0,ccs,hdb3
nethdlc=1-124:hdlc0

loadzone=us
defaultzone=us

From CommandLine

/sbin/sethdlc-new hdlc0 hdlc-eth
/sbin/ifconfig hdlc0 up

/sbin/ifconfig hdlc0 192.168.15.1 netmask 255.255.255.252 broadcast 192.168.15.3 up

Definitely I am missing something . Can anyone push me to the right direction ?

Regards,
