GVP 7.6 behind switch with 2 dialogic cards DMV-BTEP

hi everyone,

anybody have experience with installing the above with 120 ports (4 E1)? currently I managed only to set 60 ports as below:

EMPS - VCS - - Popgateway1 - Route1
channels: 1:1-30
EMPS - VCS - - Popgateway1 - Route2
channels: 2:1-30

is the above correct?

if need to copy another section for popgateway2, what value should I use for the channels?
because I tried that and EMPS gives validation error.

many thanks in advanced
